Technical Field

The present disclosure relates to the field of defrosting of a household air conditioner, and in particular, to a defrosting device, a heating apparatus, an automatic defrosting control method, and a storage medium.

Background

With the improvement of living standard, the air conditioner with heating function becomes an important household appliance when people get warm at home. The air conditioner provides a heating effect by absorbing heat in the fins of the outdoor unit and releasing heat in the indoor unit. When the air conditioner operates a heating function, the fins of the outdoor unit have a significantly lower temperature than the outdoor air because the fins of the outdoor unit absorb a large amount of heat by the heat exchange system. This makes moisture in the air easily solidify into frost crystals on the fins of the outdoor unit. The frost crystals affect the contact between the fins of the outdoor unit and the air, and further affect the heat exchange capacity of the fins of the outdoor unit, thereby affecting the normal operation of the air conditioning system.

Therefore, the frost on the fins of the outdoor unit of the air conditioner needs to be removed, the outdoor unit can be ensured to continuously exchange heat with outdoor air, and the normal operation of the air conditioner is ensured.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In the related art, there are four methods of defrosting fins of an outdoor unit of an air conditioner.

A reverse refrigeration method: the air conditioner is switched to a refrigeration mode, so that an internal heat exchange system releases heat to fins of an outdoor unit of the air conditioner, and frost crystals on the fins are melted. This method requires stopping the operation of the outdoor unit, which causes a decrease in the indoor temperature, so that the comfort of the indoor temperature during defrosting is poor.

Electric heating defrosting: an electric heater is additionally arranged in a heat exchanger of the air conditioner and is connected into a control system. Although easy to implement, the electrical heating consumes high energy, consumes a large amount of electric energy, and causes the related electric charge of the air conditioner to rise, and the economy is poor.

Hot gas bypass defrosting: the hot gas bypass pipelines are arranged on two sides of the indoor unit of the air conditioner, and liquid in the heat exchange system absorbs heat from the hot gas bypass pipelines during defrosting, does not flow through an evaporator of the indoor unit any more, does not absorb heat from the indoor space, and maintains the indoor temperature. However, the hot gas bypass passage needs to be separately arranged and is complex to control, and the compressor is easy to be in protective shutdown or break down due to liquid impact.

Heat storage and defrosting: a heat accumulator is additionally arranged in a heat exchanger of the air conditioner, the heat accumulator accumulates heat through a cylinder body of a compressor or an exhaust pipeline during heating, and when the defrosting mode is started, the heat exchanger absorbs heat from the heat accumulator and releases the heat to fins of an outdoor unit to defrost. The method needs to additionally add a heat storage module and is high in cost.

As described above, in the related art, there is no defrosting technique, which is very economical and energy-saving, and provides a user with good comfort.

Therefore, the present disclosure is made in view of the above problems, and provides an apparatus and a method for ensuring that there is no influence on continuous and stable heating of a heating device system during defrosting, so as to avoid a fault problem caused by frosting of an external unit, and simultaneously avoid an influence on indoor temperature during defrosting, thereby improving indoor comfort.

FIG. 1 is a schematic circuit diagram illustrating a defroster, according to one embodiment.

In one embodiment, as shown in fig. 1, a defrosting apparatus for defrosting fins of an outdoor unit of a heating device includes: a power supply P; a pulse capacitor 30, wherein the pulse capacitor 30 is connected with the power supply P; a coil 20, the coil 20 being connected in parallel with the pulse capacitor 30, and the coil 20 being in contact with the fin; a first switch S1, the first switch S1 being in series with the pulse capacitor 30, the first switch S1 also being in series with the coil 20; and a second switch S2, the second switch S2 being connected in series with the coil 20 and the second switch S2 being connected in parallel with the pulse capacitor 30.

In the embodiment of the present disclosure, the heating device may be any heat exchange device, and any device having a heat exchange function and fins for heat exchange may be an object of the present disclosure. In the following description, an electric appliance such as an air conditioner is exemplified. The heating apparatus described in the present disclosure may have only a heating function, and may also have a cooling function together with the heating function.

When the first switch S1 and the second switch S2 are both closed, the pulse capacitor 30 and the power source P form a path, the coil 20 and the power source P form a path, and the pulse capacitor 30 starts to provide a pulse current to the coil 20, so that the coil 20 generates a pulse magnetic field.

The pulsed magnetic field generated by the coil 20 can make the fins of the outdoor unit of the heating device receive the continuously changing magnetic force, so that the fins vibrate and the frost crystals fall off.

In one embodiment, when the first switch S1 fails to open due to a fault, the second switch S2 may open the path relationship between the coil 20 and the power source P, thereby functioning as a shutdown state and protecting the circuit.

In one embodiment, the coil 20 may be a plate coil.

In one embodiment, the first switch S1 and the second switch S2 may be relay switches.

In one embodiment, a heating apparatus includes an outdoor unit and an indoor unit, wherein the outdoor unit includes: a fin; the electromagnetic pulse device comprises a pulse capacitor and a coil, and the coil is in contact with the fin; and the control unit is used for controlling the electromagnetic pulse device to provide pulse vibration to the fins to defrost when the heating equipment meets defrosting conditions.

The electromagnetic pulse device comprises a power supply P for supplying power to said coil 20; and the switch S is arranged between the power supply and the coil and controls whether the coil is electrified or not through the opening and closing of the switch.

In one embodiment, the switches S include a first switch S1 and a second switch S2; controlling the on and off of the electromagnetic pulse device by the on and off of the first switch S1; when the first switch S1 fails, the power to the coil is turned off by closing the second switch S2.

The fins are used for contacting with air in a large area, and further the heat exchange efficiency of the heating equipment is improved.

When the heating equipment meets the defrosting condition, the control unit opens the first switch to enable the electromagnetic pulse device to be started, the coil 20 of the electromagnetic pulse device generates pulse vibration on the fin contacted with the coil 20, and the fin vibration enables frost crystals on the fin to fall off.

When the heating apparatus satisfies the exit condition, the control unit turns on the second switch S2 to stop the operation of the electromagnetic pulse device, and the defrosting operation is stopped.

In one embodiment, as shown in fig. 2, the heating apparatus includes: outdoor unit 100 and indoor unit 200. Wherein, indoor set 200 includes: an evaporator 201. The outdoor unit 100 includes: a four-way valve V1; an electromagnetic pulse device 101; a compressor 102; a condenser 103.

Refrigerant flows through the evaporator 201, the four-way valve V1, the compressor 102, and the condenser 103.

The evaporator 201 is used to vaporize a liquid refrigerant and absorb heat. The condenser 103 is used for liquefying gaseous refrigerant and releasing heat, and the condenser 103 comprises fins which can enlarge the contact area between the condenser 103 and air and strengthen the heat exchange effect of the condenser.

The compressor 102 is used to pressurize and liquefy a gaseous refrigerant to release heat or decompress and gasify a liquid refrigerant to absorb heat. The four-way valve V1 is used for controlling the flow direction of the refrigerant.

After the electromagnetic pulse device 101 is started, the coil of the electromagnetic pulse device generates pulse vibration to the fin in contact with the coil, and the fin vibration causes the frost crystals on the fin to fall off.

Based on the same conception, the invention also provides an automatic defrosting control method.

The second time threshold is a time for the heating equipment to enter the normal operating state after the overload protection is stopped and restarted, and the second time threshold may be set according to a speed for the heating equipment to enter the normal operating state again, for example, the second time threshold may be 15 minutes, 20 minutes, or 25 minutes. The third temperature threshold may be set according to a temperature of the heating device in a normal operating state, and the third temperature threshold may be 40 ℃, 42 ℃, or 45 ℃.

In one embodiment, when the compressor of the outdoor unit is operated for more than 5 minutes, the change rate of the pipe temperature of the indoor unit is lower than 1 ℃/6 minutes, and the pipe temperature of the indoor unit is lower than 42 ℃, the heating device starts the electromagnetic pulse device to enter a defrosting mode.

The third time period threshold is the time from the start of the compressor to the normal operation state, and the third time period threshold may be set according to the speed of the compressor entering the normal operation state, for example, the first time period threshold is 3 minutes or 8 minutes. The speed threshold is the temperature change rate of the pipe of the indoor unit, and can be set according to the change rate in normal operation, for example, the speed threshold can be 1.2 ℃/6 minutes or 0.8 ℃/6 minutes. The fourth temperature threshold may be set according to the temperature of the heating device in the normal operating state, and the third temperature threshold may be 40 ℃, 42 ℃ or 45 ℃.

In one embodiment, when the compressor of the outdoor unit is operated for more than 3 hours and the pipe temperature of the indoor unit is lower than 42 ℃, the heating device starts the electromagnetic pulse device to enter the defrosting mode.

The fourth time threshold is a time after the compressor enters the steady state after the compressor is operated for a long time, and the fourth time threshold may be set according to the time when the compressor enters the steady state, for example, the fourth time threshold may be 2 hours or 4 hours.

The fifth time period threshold and the sixth time period threshold may be set according to a time period for the compressor of the heating apparatus to enter the normal operation state, for example, the fifth time period threshold may be 40 minutes or 50 minutes, and the sixth time period threshold may be 15 minutes or 25 minutes. The sixth temperature threshold may be set according to a temperature of the heating device in a normal operating state, and the sixth temperature threshold may be 40 ℃, 42 ℃, or 45 ℃.

In one embodiment, said turning on said electromagnetic pulse device to enter a defrost mode when said detected operating parameter satisfies a defrost condition comprises: and manually opened through a function key. That is, the defrosting mode shown in the present disclosure may be automatically turned on or may be manually turned on, for example, an on button is provided in an air conditioner remote controller, and the defrosting mode may be turned on by turning on the button.

In the heating mode, firstly, the heating equipment is enabled to work for a certain time, the pipeline of the indoor unit and the pipeline of the outdoor unit of the heating equipment are enabled to enter working states, and then the temperatures of the two pipelines are detected, so that the condition judgment caused by the temperature in the non-working state when the equipment is started is avoided. When the temperature of the indoor unit and the temperature of the outdoor unit are both lower than the preset temperature threshold, it indicates that the operation of the heating equipment is in a low-efficiency condition, the internal heat exchange efficiency is reduced, and at this time, the defrosting mode needs to be entered.

In one embodiment, the first temperature threshold may be 0 ℃, below which moisture in the air may solidify and thereby easily frost on the fins of the heating apparatus.

After the heating equipment is shut down due to overload protection caused by excessive operation, the heating equipment is restarted, the outdoor fan and the compressor operate for a certain time, so that a pipeline of an indoor unit of the heating equipment enters a working state, and the temperature of the pipeline of the indoor unit is detected, so that the condition that the temperature of the indoor unit is influenced by the temperature of a non-working state when the equipment is started is avoided. When the temperature of the pipeline of the indoor unit is lower than the preset temperature threshold, the operation of the heating equipment is in a low-efficiency condition, the internal heat exchange efficiency is reduced, and at this time, a defrosting mode needs to be entered.

After the running time of the compressor of the outdoor unit is longer than a certain time, the change rate of the pipeline temperature of the indoor unit is lower than a preset rate threshold, and the pipeline temperature of the indoor unit is lower than a preset temperature threshold, which indicates that the temperature of the pipeline of the indoor unit is slowly raised and cannot reach a specified temperature during the normal operation of the heating equipment, indicates that the operation of the heating equipment is in a low-efficiency condition, the internal heat exchange efficiency is reduced, and at this time, the defrosting mode needs to be entered.

The temperature difference between the pipeline of the indoor unit and the pipeline of the outdoor unit is smaller than a preset temperature difference threshold value, the accumulated running time of the compressor of the outdoor unit reaches a certain time, and the temperature of the pipeline of the indoor unit is lower than the preset temperature threshold value, which indicates that the heating equipment enters a working state, but the heat exchange system cannot efficiently exchange heat, so that the pipeline of the indoor unit and the pipeline of the outdoor unit cannot be pulled apart by the preset temperature difference, the pipeline of the indoor unit also cannot reach a temperature due to the heating working state, which indicates that the heating equipment works in a low-efficiency condition, the internal heat exchange efficiency is reduced, and at this time, a defrosting mode needs to be entered.

The first temperature threshold is a preset temperature threshold of a pipeline of the outdoor unit, and the second, third, fourth, fifth and sixth temperature thresholds are preset temperature thresholds of a pipeline of the indoor unit. When the heating device works, the temperature of the pipeline of the outdoor unit is low, and the temperature of the pipeline of the indoor unit is high, so the first temperature threshold value is different from the second temperature threshold value, the third temperature threshold value, the fourth temperature threshold value, the fifth temperature threshold value and the sixth temperature threshold value.

In one embodiment, the second temperature threshold, the third temperature threshold, the fourth temperature threshold, the fifth temperature threshold, and the sixth temperature threshold may be the same or different. However, the present disclosure is not limited thereto, and the first to sixth temperature thresholds may be set according to an external environment in which the air conditioner is located.

Fig. 5 is a flow diagram illustrating an automatic defrost control method according to an exemplary embodiment. FIG. 6 is a flow diagram illustrating compressor frequency control according to an exemplary embodiment.

In one embodiment, as shown in fig. 5, the turning on the electromagnetic pulse device to enter the defrost mode includes:

s21: controlling a frequency of the compressor of the heating apparatus below a threshold frequency;

s22: starting the electromagnetic pulse device to provide vibration for fins of an outdoor unit of the heating equipment;

s23: detecting the temperature of a pipeline of an outdoor unit and the temperature of a pipeline of an indoor unit of the heating equipment;

s24: adjusting a fan gear of an indoor unit of the heating equipment to a defrosting gear;

s25: and adjusting the rotating speed of a fan of an outdoor unit of the heating equipment according to the gear of the fan of the indoor unit.

As shown in fig. 6, the controlling the frequency of the compressor of the heating device to be below a threshold frequency may include:

s211: detecting a frequency of the compressor;

s212: when the detected frequency of the compressor is greater than a frequency threshold, reducing the frequency of the compressor to the frequency threshold;

s213: maintaining the frequency of the compressor at a current frequency when the detected frequency of the compressor is less than or equal to the frequency threshold.

When the heating equipment enters a defrosting mode, the frequency of the compressor is limited to be below a threshold frequency, the compressor is prevented from working at a high frequency, and heat on a large number of fins is taken away by a refrigerant, so that the defrosting effect of the fins is influenced.

When the frequency of the compressor is lower than the threshold frequency, the compressor is controlled to maintain the current frequency.

For example, when the threshold frequency of the compressor is set to 45 hz, and when the frequency of the compressor is above 45 hz, for example, the frequency of the compressor is 60 hz, the heating device may down-convert the frequency of the compressor to 45 hz. When the frequency of the compressor is below 45 hz, for example, the frequency of the compressor is 25 hz, the heating device can maintain the frequency of the compressor at 25 hz.

And then starting the electromagnetic pulse device, wherein a coil of the electromagnetic pulse device can perform pulse vibration on the fins of the outdoor unit, so that the fins of the outdoor unit vibrate, and frost crystals are further vibrated.

In the defrosting mode, the temperature of the outdoor unit's pipe and the indoor unit's pipe is detected so that the defrosting mode can be stopped in time when the heating device breaks down. The temperature detection of the outdoor unit pipes and the indoor unit pipes may be performed in real time or periodically at regular intervals. For example, the temperature of the outdoor unit duct and the indoor unit duct may be detected every 3 seconds. However, the present disclosure is not limited thereto, and the temperature of the outdoor unit pipes and the indoor unit pipes may be detected every 5 seconds, 10 seconds, or 1 minute. The setting may be made according to the environment in which the heating apparatus is located.

The fan of the indoor unit is adjusted to a defrosting gear with a lower rotating speed in order to avoid blowing air into the room as much as possible during defrosting, but in order to avoid that a user thinks that the heating equipment is stopped.

The fan of the outdoor unit reduces the rotating speed to a gear corresponding to the fan of the indoor unit in the defrosting process so as to avoid influencing the defrosting effect.

Fig. 7 is a flow diagram illustrating an automatic defrost control method according to an exemplary embodiment. Fig. 8A to 8E are flow charts illustrating an automatic defrost control method according to an exemplary embodiment.

In one embodiment, as shown in fig. 7, the automatic defrost control method further includes:

s30: exiting the defrost mode when the detected operating parameter satisfies an exit condition.

In one embodiment, as shown in fig. 8A to 8E, the exiting the defrost mode when the detected operating parameter satisfies an exit condition includes:

exiting the defrost mode when the detected operating parameter satisfies one of the following conditions,

s31: the running time of the defrosting mode is longer than a seventh time threshold;

s32: the current value of a current detector of the heating equipment is greater than a current threshold value;

s33: after a compressor of the heating equipment is started for a first preset time, detecting that the compressor fails;

s34: after the defrosting mode is operated for a second preset time, a temperature sensor of the heating equipment breaks down;

s35: a duct temperature of an indoor unit of the heating apparatus is greater than a seventh temperature threshold, and a duct temperature of an outdoor unit of the heating apparatus is greater than an eighth temperature threshold, wherein the seventh temperature threshold and the eighth temperature threshold are different.

When the running time of the defrosting mode is longer than the seventh time threshold, the defrosting mode can meet the defrosting requirement of the fins of the outdoor unit, so the heating equipment exits the defrosting mode. In one embodiment, the seventh time period threshold may be set to 12 minutes, and the seventh time period threshold may also be set according to the defrosting speed of the heating equipment in the normal condition, for example, the seventh time period threshold may be set to 10 minutes or 15 minutes.

When the current value of the current detector of the heating equipment is larger than the current threshold value, the circuit fault occurs in the heating equipment, and the defrosting mode needs to be exited immediately to prevent the fault influence from being enlarged. The current threshold may be set according to the model of the heating apparatus.

When the compressor of the heating equipment is started for a first preset time, the compressor enters a working state, the working state of the compressor is detected, and when the compressor fails, the defrosting mode needs to be exited immediately to prevent the failure from influencing expansion. In one embodiment, the first preset time may be set to 60 seconds, and the first preset time may also be set according to a specific time when the compressor enters the working state, for example, the first preset time may be set to 45 seconds or 75 seconds.

When the defrosting mode is just operated, the temperature of each device in the heating mode does not reach the corresponding temperature, so the temperature sensor does not detect or judge the temperature data detected by the temperature sensor. After the defrosting mode is operated for the second preset time, if the parameter detected by the temperature sensor is seriously abnormal or has no parameter, the temperature sensor is indicated to have a fault, and the defrosting mode needs to be exited immediately to prevent the influence of the fault from being enlarged. In one embodiment, the second preset time may be set to 2 minutes, and the second preset time may also be set according to the specific detected temperature of the defrost mode, for example, the second preset time may be set to 100 seconds or 140 seconds.

When the pipeline temperature of the indoor unit of the heating device is greater than the seventh temperature threshold value and the pipeline temperature of the outdoor unit of the heating device is greater than the eighth temperature threshold value, it is indicated that the indoor unit and the outdoor unit of the heating device have recovered to normal working temperatures, the heat exchange function of the heating device has recovered to normal, frost crystals on fins of the outdoor unit have fallen off, and the defrosting operation is completed, so that the defrosting mode can be exited. In one embodiment, the seventh temperature threshold may be set to 18 ℃, the eighth temperature threshold may be set to 45 ℃, and the seventh temperature threshold and the eighth temperature threshold may also be set according to the specific corresponding temperatures after the defrosting of the heating device is completed, for example, the seventh temperature threshold may be 16 ℃ or 20 ℃, and the eighth temperature threshold may be 42 ℃ or 48 DEG C
