Air conditioning system

Technical Field

The utility model relates to the technical field of air conditioners, in particular to an air conditioning system.

Background

In the current air conditioning system, floor heating, wall heating, capillary networks and the like which can play a role in cold radiation can be used for detecting the temperature and the humidity on the cold radiation surface by arranging a temperature and humidity detection device on the cold radiation surface, judging whether the cold radiation surface has condensation risk according to the temperature and humidity detection value, and then a controller of the air conditioning system can be used for controlling whether the cold radiation is operated through a corresponding actuator switch.

Disclosure of utility model

In the actual use process of the air conditioning system, the applicant finds that the following problems exist: the area of the cold radiation surface of the radiation end device in the room can be relatively large, the position of the radiation end device in the room can be completely different, only a few temperature and humidity detectors can be arranged on the radiation surface, and all temperature points can not be detected at all. Moreover, there is a difference in thermal resistance at each place of the cold radiation surface, resulting in a large difference in temperature on the cold radiation surface, and a temperature and humidity detector may not be arranged at a certain local cold radiation surface, and at a certain time, the temperature may be lower than the dew point temperature, so that condensation is generated on the wall surface or the ground of the local cold radiation surface, and the local cold radiation surface may even go moldy for a long time.

Although blind areas can be reduced by increasing the number of temperature and humidity detectors in engineering application, full coverage cannot be achieved, humidity change characteristics of different positions in a room can be completely different, humidity at part of the positions is easy to be greatly increased relative to other positions, and therefore the risk of local condensation still exists in the room.

In order to solve the problem that the temperature of the local cold radiation surface may be lower than the dew point temperature due to the obvious increase of the humidity of the partial area in the first space, so that the wall surface, the ground surface and the like are exposed and moldy, an air conditioning system is provided in the embodiment of the present utility model, fig. 1 is a schematic structural diagram of the air conditioning system in one implementation manner in the embodiment of the present utility model, as shown in fig. 1, the air conditioning system in the present utility model may include: at least two humidity detection units 2 installed at different humidity variation characteristic positions in the first space 1, wherein the humidity detection units 2 are used for respectively detecting the humidity at the different humidity variation characteristic positions in the first space 1; a radiation end device 3 installed in the first space 1, the radiation end device 3 being used for temperature regulation of the first space 1.

In some embodiments, the two humidity detecting units 2 may be installed at positions close to each other in the first space 1, or may be installed at positions far from each other in the first space 1, so long as the installation positions of the two humidity detecting units 2 have different humidity variation characteristics. When two humidity detection units 2 are installed at a position far from the first space 1, and humidity at the two positions far from each other in the first space 1 is detected by the two humidity detection units 2, when a significant increase in the humidity value of a local area in the first space 1 occurs due to external factors or internal factors, at least one of the humidity detection units 2 can detect the increase in the humidity value with a greater probability, so that the air conditioning system can acquire the situation in time and perform a corresponding control operation.

For example, the humidity change characteristics may be specifically understood as that when the humidity value of a local area in the first space 1 is significantly increased due to external factors or internal factors, the change characteristics of the humidity reflected at the different humidity change characteristics are different, for example, the humidity at one location may be significantly increased or significantly decreased, and the humidity at another location may be substantially unchanged or slightly slowly increased or decreased.

In some embodiments, the first space 1 may include a first region 20 and a second region 30, and the humidity change characteristics of the first region 20 and the second region 30 are different.

As a practical matter, the first region 20 may include a region that characterizes user comfort or a location where humidity is prone to abrupt changes, and the second region 30 may include a location that characterizes integrated humidity within the first space. At least one wetness detecting unit 2 is mounted to the first region 20 and at least one wetness detecting unit 2 is mounted to the second region 30. The user comfort zone may be understood as a zone of activity where the user may often be comfortable, or a zone where the space is relatively wide such that the user is in a relatively comfortable zone, rather than some narrow, remote corner zones. The position where the humidity is liable to be suddenly changed is understood as a position where the humidity is greatly raised or lowered in a short time due to external interference or interference of internal self factors. The first spatial integrated humidity is understood to mean the general humidity of the first space 1 as a whole, that is to say the second region 30 is advantageous in such a way that the humidity detected by the humidity detection unit 2 characterizes the integrated humidity in the first space.

In the application, at least two humidity detection units 2 are arranged at different humidity change characteristic positions in the first space 1 to respectively detect the humidity at the different humidity change characteristic positions in the first space 1, so when the humidity of a local area in the first space 1 obviously rises, the humidity detection unit 2 timely detects that the humidity obviously rises, the radiation end equipment 3 in the first space 1 can be timely controlled to stop running, and the possibility of condensation on a cold radiation surface corresponding to the radiation end equipment 3 in the local area in the first space 1 can be effectively reduced or avoided, thereby reducing the possibility of condensation and mildew on a wall surface, a ground surface and the like, and further improving the experience of users.

For example, locations where humidity is subject to abrupt changes may include locations near the door 10 or window or humidifier, and so forth. Once the door 10 or window or humidifier 11 is opened. The humidity at a location near the door 10 or window or humidifier 11 is intended to be prone to abrupt changes, such as an increase in humidity and an increase in rate of change. The location characterizing the integrated humidity of the first space may comprise an air return or air outlet of the convection end-device 4 located in the first space 1 or in an air flow channel inside the convection end-device 4 or in an outer wall of the housing of the convection end-device 4, etc. The air at the above location flows more and its humidity is relatively easily accessible or equal to the first spatial integrated humidity.

In other possible embodiments, the humidity of the first region 20 may fluctuate more than the humidity of the second region 30. At least one wetness detecting unit 2 is disposed in the first region 20 and at least one wetness detecting unit 2 is disposed in the second region 30.

In the above manner, when the humidity value of the local area in the first space 1 is significantly increased due to external factors or internal factors, the at least one humidity detection unit 2 located in the first area 20 can detect the increase in the humidity value with a greater probability and increase the rate of change, so that the air conditioning system can acquire the situation in time and perform a corresponding control operation.

The radiation end device 3 is an end device for adjusting the temperature and humidity of the gas in the first space 1 mainly by means of radiation heat exchange. In some embodiments, the radiation end device 3 may include at least one of, but not limited to: floor heating, wall heating, capillary networks, radiators, and the like. The radiation surface of the radiation end device 3 corresponding to the heat exchange with the air may include at least one of, but not limited to: wall surfaces, ground surfaces, outer wall surfaces of heat exchange equipment, and the like.

For example, when the radiation end device 3 is a floor heating, the cold radiation surface is the floor; when the radiation end equipment 3 is a wall, the cold radiation surface is a wall surface; when the radiation end device 3 is a capillary network, the cold radiation surface can be a wall surface at the position of the capillary network according to the specific laying arrangement of the capillary network; when the radiation end device 3 is a radiator, the cold radiation surface may be an outer wall surface of a heat exchange device (radiator). When cold radiation face is the wall, at a certain time its temperature can be less than dew point temperature and lead to the wall that this local cold radiation face corresponds to appear the condensation, and the wall just appears moldy easily for a long time, if the condensation is serious, the water on the wall can flow down the ground of whereabouts below for the water stain appears on ground, influences user experience and feels. If the cold radiation surface is the wall surface of the radiator, the temperature of the cold radiation surface is lower than the dew point temperature at a certain time, so that the wall surface corresponding to the local cold radiation surface is exposed, and the exposed on the radiator can drop to the ground below in a large amount, so that water stains appear on the ground, and the user experience is influenced.

In some embodiments, as shown in fig. 1, the air conditioning system may further include: a heat convection end device 4, at least one heat convection end device 4 being mounted in the first space 1 for temperature and humidity conditioning of the first space 1. The heat convection end device 4 is an end device for adjusting the temperature and humidity of the gas in the first space 1 mainly by means of heat convection. As applicable, the convective heat transfer end device 4 may include at least one of, but not limited to: fan coils, chilled beams, air conditioning internals, and the like. The air conditioner indoor unit is provided with a heat exchanger for flowing through a refrigerant and is used for adjusting the temperature and the humidity of the air in the first space 1, such as a wall-mounted air conditioner indoor unit, a vertical air conditioner indoor unit and the like.

In some embodiments, as shown in fig. 1, an air conditioning system may include: an air conditioner external unit 6 and a throttle unit for throttling the refrigerant compressed by the compressor. The air conditioner external unit 6 may include a compressor, a first heat exchange unit. When the convection heat exchange terminal device 4 includes an air conditioner indoor unit, a heat exchanger in the air conditioner indoor unit may be combined with the throttling unit, the first heat exchange unit and the compressor to form an air conditioning system, so as to realize a refrigerating function. The refrigerating function and the heating function of the air conditioner indoor unit can be respectively realized by changing the sequence of the refrigerant compressed by the compressor flowing through the first heat exchange unit and the heat exchanger in the air conditioner indoor unit.

In some embodiments, as shown in fig. 1, an air conditioning system may include: and an energy supply device 7. The power supply means 7 may include: and the second heat exchange unit is provided with a first heat exchange flow passage and a second heat exchange flow passage which can exchange heat, and two ends of the first heat exchange flow passage exchange refrigerant with the compressor and the first heat exchange unit in the air conditioner external unit 6 respectively. When the energy supply device 7 is in the cooling operation, the refrigerant flowing out of the outlet of the compressor passes through the first heat exchange unit and the throttling unit, enters the second heat exchange unit, and then returns to the inlet of the compressor. When the energy supply device 7 is in heating operation, the refrigerant flowing out of the outlet of the compressor passes through the second heat exchange unit and the throttling unit, enters the first heat exchange unit, and then returns to the inlet of the compressor. The two ends of the second heat exchange flow channel can be communicated with the radiation end device 3 and the convection end device 4. Water can be introduced into the second heat exchange flow passage. The second heat exchange flow passage may be driven by driving a pump to supply water subjected to heat exchange with the refrigerant in the first heat exchange flow passage to the radiation end device 3, the convection end device 4.

In some embodiments, the energy supply device 7 may be a separate device from the air conditioner external unit 6, and the energy supply device 7 may be installed in the air conditioner external unit 6.

In some embodiments, as shown in fig. 1, an air conditioning system may include: a temperature detection unit 5, at least one temperature detection unit 5 being arranged to detect the temperature in the first space 1. Further, the temperature detecting unit 5 is disposed at a position where the average temperature of the first space 1 can be detected as much as possible, and is prevented from being disposed at the air outlet of the heat convection end device 4 or close to or near the radiation end device 3, thereby preventing the detected temperature from being lower than the true average temperature of the first space 1.

As a possibility, the temperature detection unit 5 may be provided at least at one of: an air conditioning system controller 8, a convection end-unit 4, an air detection device 9, and so on. The air detection means 9 may detect a state parameter of the air, which may be arranged at a certain position within the first space 1. As a practical matter, the air detection means 9 may be movable. For example, the air detection device 9 may communicate with the air conditioning system by wireless communication, or may communicate with the air conditioning system by power line communication. The air conditioning system controller 8 may be a controller for implementing functions of controlling the operation or stop of the corresponding terminal device of the first space 1, changing the set temperature of the first space 1, setting a mode, displaying the current temperature of the first space 1, and the like.

As a possibility, the position of the humidity detection unit 2 may be installed at least at one of: a convection heat transfer end equipment 4, an air conditioning system controller 8, an air detection device 9, and so forth. When the humidity detection unit 2 is disposed at the convection end device 4, the humidity detection unit 2 may be away from the air outlet of the convection end device 4, so that the humidity detection unit 2 obtains accurate humidity at the installation position of the convection end device 4. The humidity detection unit 2 may be specifically located at an air return opening or an air outlet of the heat convection end device 4 or an air flow channel inside the heat convection end device 4 or at an outer wall of a casing of the heat convection end device.

In some embodiments, an air conditioning system may include: and a control unit. The control unit can be electrically connected with the humidity detection unit and the radiation end equipment, and is used for controlling the radiation end equipment according to the humidity value detected by the humidity detection unit so as to control the opening or closing of the radiation end equipment. Further, the air conditioning system may have a first state. In the first state, the air conditioning system is in an operating state, and all humidity values detected by the humidity detection units in the first space are in a stable state. The steady state may be that the rate of change of the humidity detected by the humidity detecting units tends to be stable, for example, the fluctuation per hour of the humidity detected by all the humidity detecting units 2 in the first space 1, respectively, is within 5%.

Further, the control unit can be electrically connected with the temperature detection unit, and the control unit is used for controlling the radiation end equipment according to the humidity value detected by the humidity detection unit and the temperature detected by the temperature detection unit. In the first state, the temperature of the fluid in the radiation end device 3 or the temperature of the wall of the radiation end device 3 corresponding to the heat exchange with air is higher than the dew point temperature corresponding to the temperature of the first space 1 and the humidity value of the first space 1. By the method, the problem that condensation occurs on the cold radiation surface corresponding to the radiation end device 3 in the first space 1 when the humidity in the first space 1 is slowly increased and exceeds the early warning value humidity can be solved.

In some embodiments, when the humidity values respectively detected by the humidity detection units 2 corresponding to the first space 1 are not completely equal, the dew point temperature may be obtained from the maximum value among the temperature of the first space 1 and the humidity values detected by all the humidity detection units 2. By the above manner, even if the humidity values detected by different humidity detection units 2 have precision deviation or one or more humidity detection units 2 are damaged to cause distortion, the maximum value in the detected humidity values of the first space 1 is used for calculating the dew point temperature, so that the radiation end device 3 can be effectively prevented from being started or restored to operate prematurely, and the corresponding cold radiation surface of the radiation end device 3 is ensured not to be exposed.

As a possibility, in the first state, the convective heat transfer end device 4 may be in an operating state or in a closed state, as is true in the present application.

In some embodiments, fig. 3 is a schematic diagram of a difference value of humidity values detected by the humidity detecting unit in an embodiment of the present utility model exceeding a preset deviation range in one case, and fig. 4 is a schematic diagram of a difference value of humidity values detected by the humidity detecting unit in another case exceeding a preset deviation range in another case, as shown in fig. 3 and fig. 4, in a first state, all humidity values detected by the humidity detecting units 2 are stable and the difference value exceeds the preset deviation range, and a dew point temperature may be obtained according to a temperature of the first space 1 and a maximum humidity value detected by all the humidity detecting units 2.

When the difference between the humidity values detected by the humidity detecting units 2 exceeds the preset deviation range, for example, two humidity values detected by the two humidity detecting units 2 exceed the preset deviation range, it may occur that the humidity value detected by one humidity detecting unit 2 is accurate and the other humidity detecting unit 2 is abnormal, and the detected humidity value is not accurate at all, so that the difference between the two humidity values exceeds the preset deviation range. In this case, since the air conditioning system cannot determine which is abnormal, in order to ensure that condensation does not occur on the cold radiation surface corresponding to the radiation end device 3, the humidity value of the first space 1 is always obtained from the maximum humidity values detected by all the humidity detection units 2 corresponding to the first space 1. Even if the maximum humidity value is abnormally erroneous, taking the abnormally erroneous maximum humidity value as the humidity value of the first space 1 only contributes to the fact that no condensation occurs on the cold radiation surface corresponding to the radiation end device 3.

In some embodiments, the control unit may also be electrically connected to the convective heat transfer end device 4. The control unit may be configured to control the radiation end device 3 and the convection end device 4 according to the humidity value detected by the humidity detection unit 2, so as to control the opening or closing of the radiation end device and the opening or closing of the convection end device. Further, the air conditioning system may have a second state. In the second state of the air conditioning system, the radiation end equipment is in a closed state, and the convection heat exchange end equipment 4 is in an operating state; the humidity value detected by at least one humidity detecting unit 2 is in a continuously rising state, or the humidity value detected by at least one humidity detecting unit 2 is larger than the humidity value detected by all the humidity detecting units 2 in the first state to be in a stable state.

As a possibility, when the humidity value detected by the at least one humidity detecting unit is in a continuously rising state, the humidity value being in a continuously rising state may be a rise in the rate of change of the humidity detected by the humidity detecting unit 2 up to 10% per hour or more. With this embodiment, the air conditioning system can determine that the rise in humidity occurs and that the rate of change is significantly increased. Further, when the rate of change of the rise in humidity reaches 10% per hour, it is considered that the rate of change of the rise may cause dew generation on the local cold radiation surface.

As a possibility, the humidity values detected by the at least one humidity detection unit 2 being greater than the humidity values detected by all humidity detection units 2 in the first state in the steady state may be that the humidity in at least a partial area of the first space 1 has increased significantly and the increase has ended, so that in the second state the humidity has not increased continuously.

When the humidity of the local area in the first space 1 is obviously increased or the obvious increase is finished, the air conditioning system can be switched to be in a second state, and the possibility of condensation on the cold radiation surface corresponding to the radiation end equipment 3 of the local area in the first space 1 can be effectively reduced or avoided through the second state, so that the possibility of condensation and mildew on the wall surface, the ground surface and the like is reduced.

When the air conditioning system is in the second state, a local area in the first space 1 may have moisture entering or generating, for example, the outside of the first space 1 is relatively wet, a window or door portion of the first space 1 is opened, and the moisture entering the first space 1 may not cause the humidity of the whole space to rise, but may raise the humidity of the first area 20 near the entry of the moisture. For another example, when the humidifier is turned on, the humidity of the entire first space 1 may not be greatly increased in a short time, but the humidity of the first area 20 where the humidifier is located, particularly, a small part of the area around the outlet of the air humidifier, is inevitably greatly increased.

At this time, there may occur two cases where at least one humidity detecting unit 2 may be located at a position where the humidity value significantly increases, and the humidity value detected by the humidity detecting unit 2 may be the position where the humidity value is maximum in the first space 1. In another case, at least one humidity detection unit 2 may be located at another position apart from the position where the humidity value significantly increases, the humidity detection unit 2 being able to detect only a small increase in the humidity at the other position due to the influence of the position where the humidity value significantly increases, but being unable to detect the humidity value at the position where the humidity value significantly increases in the first space 1.

In the prior art, fig. 2a is a schematic diagram of a humidity detection unit in the prior art, which controls a radiation end device by comparing a maximum value or an average value with an early warning value, as shown in fig. 2a, an air conditioning system collects a plurality of humidity values detected by a plurality of humidity detection units 2 located in a first space 1, and controls a radiation end device 3 in the first space 1 to stop running when the maximum value or the average value in the plurality of humidity values reaches the early warning value humidity corresponding to the temperature of the first space 1 at the moment, so as to avoid the problems of condensation and the like on a cold radiation surface of the radiation end device 3. However, the above solution has a problem that when the humidity of only a local area in the first space 1 increases substantially, the average value of the plurality of humidity values detected by the plurality of humidity detection units 2 distributed at different positions in the first space 1 may not reach the early warning value humidity, which may cause the radiation end device 3 in the first space 1 to stop operating all the time. If the radiation end device 3 is installed at a local area where the humidity is greatly increased, condensation occurs on a cold radiation surface corresponding to the radiation end device 3 of the local area, but the existing air conditioning system cannot avoid the occurrence of condensation in the above-mentioned scene. When the humidity of only a local area in the first space 1 increases substantially, even if the maximum value among the plurality of humidity values detected by the plurality of humidity detecting units 2 distributed at different positions in the first space 1 is used to control whether the radiation end device 3 in the first space 1 stops operating, the problem of condensation of the local area still exists. The specific scene is as follows, humidity of a local area in the first space 1 rises greatly, and the maximum humidity of the local area exceeds the early warning value humidity. However, the humidity detection unit 2 may not be provided at the local area, the humidity detection unit 2 closest to the local area is located at another area at a distance from the local area, the humidity detection unit 2 of the other area is capable of detecting a rise in humidity, but the value after the rise in humidity is detected by the other area is far less than the maximum humidity of the local area due to the distance, the value after the rise in humidity is detected by the other area is less than the early warning value humidity, and in the above case, the air conditioning system still does not control the radiation end device 3 in the first space 1 to stop operation. However, if the radiation end device 3 is installed in a local area where the humidity greatly increases, dew appears on the cold radiation surface corresponding to the radiation end device 3 in the local area, and the existing air conditioning system cannot avoid the dew generation in the above-mentioned scene.

FIG. 2b is a schematic diagram of the humidity detecting unit detecting an increase in the humidity value to control the radiation end device according to the embodiment of the present application, as shown in FIG. 2b, since the air conditioning system according to the present application has the second state, in which the radiation end device 3 is in the closed state and the convection end device 4 is in the operating state; the humidity value detected by at least one humidity detecting unit 2 is in a continuously rising state, or the humidity value detected by at least one humidity detecting unit 2 is larger than the humidity value detected by all the humidity detecting units 2 in the first state to be in a stable state. Therefore, when the humidity rises above the early warning value humidity in the local area in the first space 1, it can be avoided that the humidity detection unit 2 in the first space 1 cannot detect the humidity value exceeding the early warning value humidity without controlling the radiation end device 3 in the first space 1 to stop operation.

In some embodiments, the probability of the first region 20 is greater than the probability of the second region 30 when a significant increase in the humidity value occurs in a localized region within the first space 1. Of course, a significant increase in the humidity value of both the first region 20 and the second region 30 may also occur.

When there is no significant increase in the local area humidity value in the first space 1 and the humidity value in the first space 1 drops to a steady state, the air conditioning system may be switched to be in the first state again.

In some embodiments, the air conditioning system further has a third state, in which the temperature of the first space 1 reaches the user set temperature, the humidity values detected by all the humidity detection units 2 are stable, the difference is stable within a preset deviation range, and the convective heat transfer terminal device is in a low-gear operation state. The air output of the convection heat exchange terminal equipment 4 is in low-grade operation, so that the air output of the convection heat exchange terminal equipment 4 always exists, and the air in the first space 1 can be promoted to generate certain flow by utilizing the air output, on one hand, the humidity of each different area in the first space 1 can be enabled to approach, the excessively high or excessively low humidity of the local area in the first space 1 is avoided, and the possibility of condensation on the cold radiation surface corresponding to the radiation terminal equipment 3 in the local area in the first space 1 can be reduced as much as possible; on the other hand, the humidity values detected by the humidity detecting unit 2 at different humidity variation characteristic positions in the first space 1 can be made to more reflect the average humidity value in the first space 1.

In some embodiments, an air conditioning system may include: and at least one humidity detection unit installed in the second space, the humidity detection unit being used for detecting the temperature in the second space. The radiation end device for temperature conditioning the first space also passes through the second space for temperature conditioning the second space. The control unit is also electrically connected with the humidity detection unit in the second space. The control unit is used for controlling the radiation end equipment according to the humidity values detected by the humidity detection unit in the first space and the humidity detection unit in the second space. The air conditioning system may have a fourth state. In the fourth state, the radiation end equipment is in a closed state; the humidity value detected by the humidity detecting unit in at least one first space or the humidity value detected by the humidity detecting unit in at least one second space is in a continuously rising state, or the humidity value detected by the humidity detecting unit in at least one first space is larger than the humidity value detected by all the humidity detecting units in the first space in a stable state, or the humidity value detected by the humidity detecting unit in at least one second space is larger than the humidity value detected by all the humidity detecting units in the second space in a previous state.

Through the fourth state of the air conditioning system, the possibility that the radiation end device 3 for adjusting the temperature of the first space 1 is exposed to the cold radiation surface corresponding to the second space can be effectively reduced or avoided, and the possibility that the wall surface, the ground and the like of the second space are exposed to the mold is reduced.
