Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
An air conditioning system, a control method and apparatus thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioning system according to an embodiment of the present invention. As shown in fig. 1, the control method of the air conditioning system according to the embodiment of the present invention includes the following steps:
s101: and acquiring the current return air temperature of the indoor unit, and updating the target working temperature of the indoor unit in real time by using the current return air temperature.
It should be noted that, in an inverter air conditioning system, in order to achieve the effect that cooling at startup can be rapidly reduced or heating at startup can be rapidly increased, the target operating temperature (the evaporation temperature during cooling operation and the condensation temperature during heating operation) of the indoor unit needs to be adjusted.
The returnable air temperature can be detected by a return air temperature sensor, and the return air temperature sensor can be arranged at a return air inlet of the indoor unit.
As a possible embodiment, the target operating temperature may be determined according to a mapping relationship between the return air temperature and the target operating temperature.
Specifically, the working mode of the air conditioning system can be identified, and the target working temperature of the indoor unit can be updated in real time according to the working mode and the return air temperature.
For example, as shown in fig. 2, in the embodiment of the present invention, when the air conditioning system performs a cooling operation, the target operating temperature (evaporating temperature) of the indoor unit is inversely proportional to the return air temperature, that is, the higher the return air temperature is, the lower the target evaporating temperature is, and the lower the return air temperature is, the higher the target evaporating temperature is; similarly, as shown in fig. 3, when the air conditioning system is in heating operation, the target operating temperature (condensing temperature) of the indoor unit is also in inverse proportion to the return air temperature.
According to one embodiment of the invention, the air conditioning system can comprise at least one indoor unit, and specifically, the current return air temperature of the at least one indoor unit can be obtained, and the average value of the at least one return air temperature can be calculated.
That is to say, when a plurality of indoor units participate in temperature regulation in the air conditioning system, the current return air temperature of the indoor units participating in temperature regulation can be collected in real time, the average value of the current return air temperatures is used as the return air temperature of the current air conditioning system, and then the target working temperature of the indoor unit is determined according to the return air temperature of the current air conditioning system.
Therefore, the control method provided by the embodiment of the invention can adjust the target working temperature of the indoor unit according to the return air temperature acquired in real time, so as to control the power of the compressor according to the changed target working temperature.
S102: and detecting the current actual working temperature of the indoor unit.
The indoor unit can be provided with an actual working temperature detection device so as to detect the actual evaporation temperature when the air conditioning system works in a refrigerating mode and detect the actual condensation temperature when the air conditioning system works in a heating mode.
S103: and controlling the power of the compressor according to the target working temperature and the actual working temperature.
That is, when the air conditioning system is in operation, the actual operating temperature of the indoor unit is made to approach the target operating temperature as much as possible by controlling the operating power of the compressor, so that the indoor temperature can meet the user's demand as soon as possible.
As a possible embodiment, as shown in fig. 4, step S103 may specifically include:
s201: and acquiring deviation amount of the target working temperature and the actual working temperature.
S202: and determining the power adjustment amount of the compressor according to the deviation amount.
That is, the deviation amount may be calculated according to the target operating temperature and the actual operating temperature of the indoor unit, and then the power adjustment amount of the compressor may be determined according to the deviation amount, so that the actual operating temperature may reach the target operating temperature by adjusting the operating power of the compressor according to the power adjustment amount.
Specifically, when the operation mode is the cooling mode, as shown in fig. 5, step S103 specifically includes:
s311: and judging whether the actual working temperature is higher than the target working temperature.
S312: if yes, the power of the compressor is increased according to the power adjustment amount.
S313: if not, the power of the compressor is reduced according to the power adjustment amount.
Specifically, when the operation mode is the heating mode, as shown in fig. 6, step S103 specifically includes:
s321: and judging whether the actual working temperature is higher than the target working temperature.
S322: if so, the power of the compressor is reduced according to the power adjustment amount.
S323: if not, the power of the compressor is increased according to the power adjustment amount.
Further, when the actual operating temperature is equal to the target operating temperature, the compressor is controlled to maintain the current power.
That is, in the refrigeration mode of the air conditioning system, the higher the return air temperature is, the lower the target evaporation temperature is, the higher the output power of the compressor is, the better the refrigeration effect of the indoor unit is, so as to realize the rapid cooling of the indoor side, the target evaporation temperature is gradually increased along with the reduction of the return air temperature, the output power of the compressor is reduced, and finally, when the actual evaporation temperature is equal to the target evaporation temperature, the output power of the compressor is kept unchanged; the air conditioning system is under the heating mode, and the return air temperature is lower, and the target condensing temperature is higher, and compressor output is bigger, and indoor set heating effect is better to realize indoor side's rapid heating up, along with the rising of return air temperature, the target condensing temperature reduces gradually, and compressor output reduces, and finally when actual condensing temperature equals the target condensing temperature, compressor output maintains unchangeably.
Therefore, the control method provided by the embodiment of the invention can adjust the compressor in real time according to the target working temperature and the actual working temperature, so that the indoor temperature can be rapidly cooled or heated to meet the temperature requirement of a user, and finally the indoor temperature is maintained in a comfortable temperature range, thereby improving the user experience.
According to an embodiment of the present invention, as shown in fig. 7, when the air conditioning system performs a cooling operation, the control method specifically includes:
s411: and (5) refrigerating and starting the air conditioning system.
S412: and acquiring the return air temperature of at least one indoor unit, and calculating the average value of the return air temperature.
S413: and acquiring the target evaporation temperature according to the refrigeration control logic.
S414: and judging whether the actual evaporation temperature is greater than the target evaporation temperature.
If so, go to step S415; if so, go to step S416; if so, step S417 is performed.
S415: the control increases the output power of the compressor and returns to step S414.
S416: the control reduces the output power of the compressor and returns to step S414.
S417: the current compressor output is maintained.
According to an embodiment of the present invention, as shown in fig. 8, when the air conditioning system is in heating operation, the control method specifically includes:
s421: and the air conditioning system is started up by heating.
S422: and acquiring the return air temperature of at least one indoor unit, and calculating the average value of the return air temperature.
S423: and acquiring the target condensation temperature according to the heating control logic.
S424: and judging whether the actual condensation temperature is greater than the target condensation temperature.
If so, go to step S415; if so, go to step S416; if so, step S417 is performed.
S425: the control reduces the output power of the compressor and returns to step S424.
S426: the control increases the output power of the compressor and returns to step S424.
S427: the current compressor output is maintained.
In summary, according to the control method of the air conditioning system in the embodiment of the present invention, the current return air temperature of the indoor unit is obtained in real time, the target working temperature of the indoor unit is updated in real time by using the current return air temperature, and then the power of the compressor is controlled according to the target working temperature and the actual working temperature, so that the power of the compressor is dynamically adjusted while the target working temperature is changed according to the return air temperature, so that the indoor temperature can meet the user requirement as soon as possible, and finally, the indoor temperature is maintained within a comfortable range.
