[0002] When an air conditioner is in heating operation in winter, the temperature around the outdoor heat exchanger is low because the air conditioner outdoor unit absorbs heat from outdoor air, and the water vapor in the air will condense into frost and adhere to the surface of the outdoor heat exchanger. Thick frost will reduce the heat exchange capacity of the air conditioner outdoor unit, thereby reducing the heating efficiency of the air conditioner. The existing technology is to switch the operation state of the air conditioner to the refrigeration cycle mode, so that the high-temperature and high-pressure refrigerant discharged by the compressor is discharged into the air conditioner outdoor unit through the four-way valve to melt the frost layer on the air conditioner outdoor unit.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0033] In the embodiments of the present disclosure, the execution subject of the defrosting method is an electronic device, and the electronic device is a server, a computer, or an air conditioner, etc.

[0034] In some embodiments, when the electronic device is a server or a computer, the server or the computer is connected to the air conditioner through the Internet. The air conditioner includes a compressor, a first heat exchange device connected to the compressor through a regulating valve, a second heat exchange device connected to the first heat exchange device through a pipeline, the second heat exchange device is arranged on a heat exchanger, and the second heat exchange device stores an intermediate medium. The server or the computer heats the heat exchanger by controlling the opening or closing of the regulating valve, thereby defrosting the heat exchanger.

[0035] In some embodiments, the electronic device is an air conditioner. The air conditioner comprises a compressor, a first heat exchange device connected to the compressor through a regulating valve, a second heat exchange device connected to the first heat exchange device through a pipeline, the second heat exchange device is arranged on a heat exchanger, and the second heat exchange device stores intermediate medium. The air conditioner controls the opening or closing of the regulating valve to heat the heat exchanger to defrost the heat exchanger.

[0036] In combination Figure 1 As shown in the drawings, the air conditioner provided by the embodiments of the present disclosure comprises a compressor 1, a first heat exchange device 2, a second heat exchange device 3, and a heat exchanger 4. The first heat exchange device is connected to the compressor through a regulating valve, the first heat exchange device is connected to the second heat exchange device through a pipeline, the second heat exchange device is arranged on the heat exchanger, and the second heat exchange device stores intermediate medium.

[0037] In combination Figure 2 As shown in the drawings, the air conditioner provided by the embodiments of the present disclosure comprises a compressor 1, a first heat exchange device 2, a second heat exchange device 3, and a heat exchanger 4. The first heat exchange device is connected to the compressor through a regulating valve, the first heat exchange device is connected to the second heat exchange device through a pipeline, the second heat exchange device is arranged on the heat exchanger, and the second heat exchange device stores intermediate medium.

[0038] In step S201, the electronic device obtains the frosting condition of the heat exchanger, and the frosting condition is used to represent whether the heat exchanger is frosted or not.

[0039] In step S202, in the case that the heat exchanger is frosted, the electronic device determines the running state of the air conditioner, wherein the running state represents whether the air conditioner is running or not.

[0040] In step S203, in the case that the air conditioner is running, the electronic device triggers the regulating valve to open, so that the refrigerant flows from the compressor into the first heat exchange device to heat the intermediate medium in the second heat exchange device.

[0041] By using the method for defrosting provided by the embodiments of the present disclosure, in the case that the air conditioner is running and needs to be defrosted, the regulating valve is directly triggered to open, so that the refrigerant flows from the compressor into the first heat exchange device to heat the intermediate medium in the second heat exchange device. Since the second heat exchange device is arranged on the heat exchanger, and the refrigerant flowing out of the compressor is a high-temperature and high-pressure gas, in the case that the refrigerant flows from the compressor into the first heat exchange device, the temperature of the intermediate medium in the second heat exchange device will rise, thereby achieving the effect of heating and defrosting the surface of the heat exchanger. In this process, the defrosting effect can be achieved without switching the running state of the air conditioner, thereby reducing the fluctuation of the indoor temperature and improving the user experience of using the air conditioner.

[0042] In some embodiments, the intermediate medium is water.

[0043] Optionally, the second heat exchange device is provided with a flow valve, and after triggering the adjusting valve to open, the method further comprises: acquiring the frost thickness of the heat exchanger; determining a target temperature according to the frost thickness; and triggering the flow valve to open in a case where the temperature of the heat-exchanged intermediate medium is greater than the target temperature. In this way, part of the intermediate medium can be heated to reach the target temperature more quickly. Meanwhile, the heat exchanger surface can be heated by using the intermediate medium reaching the target temperature, so that the frost can be melted more quickly.

[0044] In combination with Figure 3 The embodiments of the present disclosure provide a method for defrosting, applied to an air conditioner, the air conditioner comprising a compressor, a first heat exchange device connected to the compressor through an adjusting valve, a second heat exchange device connected to the first heat exchange device through a pipeline, the second heat exchange device being arranged on a heat exchanger, and the second heat exchange device storing an intermediate medium, and the second heat exchange device being provided with a flow valve, the method comprising:

[0045] In step S301, the electronic device acquires the frost condition of the heat exchanger, and the frost condition is used to represent whether the heat exchanger is frosted or not.

[0046] In step S302, in a case where the heat exchanger is frosted, the electronic device determines the running state of the air conditioner, wherein the running state represents whether the air conditioner is running or not.

[0047] In step S303, in a case where the air conditioner is running, the electronic device triggers the adjusting valve to open, so that the refrigerant flows from the compressor into the first heat exchange device to heat the intermediate medium in the second heat exchange device.

[0048] In step S304, the electronic device acquires the frost thickness of the heat exchanger.

[0049] In step S305, the electronic device determines a target temperature according to the frost thickness.

[0050] In step S306, in a case where the temperature of the heat-exchanged intermediate medium is greater than the target temperature, the electronic device triggers the flow valve to open.

[0051] The method for defrosting provided by the embodiment of the present disclosure can directly trigger the regulating valve to open when the air conditioner is running and defrosting is needed, so that the refrigerant flows from the compressor to the first heat exchange device to exchange heat with the intermediate medium in the second heat exchange device. Since the second heat exchange device is arranged on the heat exchanger and the refrigerant flowing from the compressor is a high-temperature and high-pressure gas, the temperature of the intermediate medium in the second heat exchange device will rise when the refrigerant flows from the compressor to the first heat exchange device, thereby achieving the effect of heating and defrosting the surface of the heat exchanger. In this process, even if the air conditioner is running in a heating state, it is not necessary to switch the air conditioner to a cooling state to achieve the defrosting effect, thereby reducing the fluctuation of the indoor temperature and improving the user experience of using the air conditioner. Moreover, the frost thickness of the heat exchanger is obtained, and the target temperature is determined according to the frost thickness. Then, the flow valve is triggered to open when the temperature of the intermediate medium after heat exchange is greater than the target temperature. The part of the intermediate medium can be heated to reach the target temperature more quickly. At the same time, the surface of the heat exchanger can be heated more quickly by using the intermediate medium reaching the target temperature.

[0052] Further, the target temperature is determined according to the frost thickness, including: matching the target temperature corresponding to the frost thickness in a preset first database. The first database stores the corresponding relationship between the frost thickness and the target temperature. The higher the target temperature is, the greater the corresponding frost thickness is.

[0053] In some embodiments, when the frost thickness is less than or equal to 1 millimeter, the target temperature corresponding to the frost thickness is 40 degrees Celsius. When the frost thickness is greater than 1 millimeter and less than or equal to 5 millimeters, the target temperature corresponding to the frost thickness is 70 degrees Celsius. When the frost thickness is greater than 5 millimeters, the target temperature corresponding to the frost thickness is 90 degrees Celsius.

[0054] Optionally, triggering the flow valve to open includes: determining a target valve opening degree according to the frost thickness. The flow valve is triggered to open at the target valve opening degree. Since the opening degree of the flow valve affects the flow speed of the intermediate medium in the second heat exchange device, thereby affecting the heating speed of the second heat exchange device to the heat exchanger. Therefore, by determining the target valve opening degree according to the frost thickness, the target valve opening degree can change with the change of the frost thickness, thereby enabling the defrosting to be completed more quickly.

[0055] Further, the target valve opening degree is determined according to the frost thickness, including: matching the target valve opening degree corresponding to the frost thickness in a preset second database. The second database stores the corresponding relationship between the frost thickness and the target valve opening degree.

[0056] In some embodiments, when the frost thickness is less than or equal to 1 millimeter, the target valve opening degree corresponding to the frost thickness is half opening. When the frost thickness is greater than 1 millimeter, the target valve opening degree corresponding to the frost thickness is full opening.

[0057] Optionally, the frost thickness of the heat exchanger is obtained by: obtaining image information of the heat exchanger; and inputting the image information into a preset frost thickness identification model to obtain the frost thickness of the heat exchanger.

[0058] Optionally, the frost thickness detection device is arranged on the heat exchanger, and the frost thickness on the heat exchanger is obtained by: sending a thickness detection instruction to the frost thickness detection device to trigger the frost thickness detection device to feed back the detected frost thickness.

[0059] Optionally, the frost condition of the heat exchanger is obtained by: obtaining the frost condition of the heat exchanger when the outdoor environment temperature is less than a preset temperature and the outdoor environment humidity is less than a preset humidity.

[0060] Optionally, the heat exchanger is arranged in an air conditioner outdoor unit. When the air conditioner operates in a heating mode, the outdoor heat exchanger of the air conditioner absorbs heat in the air to reduce the surface temperature of the outdoor heat exchanger. At this time, if the outdoor environment temperature is low and the outdoor environment humidity is large, the surface of the outdoor heat exchanger is prone to frost. Therefore, by obtaining the frost condition of the heat exchanger when the outdoor environment temperature is less than a preset temperature and the outdoor environment humidity is less than a preset humidity, unnecessary detection steps can be reduced.

[0061] Optionally, after determining the operating state of the air conditioner, the method further comprises: controlling the air conditioner to operate in a cooling mode when the air conditioner is in a non-operating state. In this way, the high-temperature and high-pressure refrigerant discharged by the compressor can be discharged into the air conditioner outdoor unit through the four-way reversing valve, thereby melting the frost layer on the heat exchanger.

[0062] In some embodiments, the outdoor environment temperature is the temperature of the area where the air conditioner outdoor unit is located. The outdoor environment humidity is the humidity of the area where the air conditioner outdoor unit is located.

[0063] Further, a temperature sensor is arranged on the surface of the heat exchanger. The outdoor environment temperature is obtained by: sending a temperature acquisition instruction to the temperature sensor to trigger the temperature sensor to feed back the detected temperature.

[0064] Further, a humidity sensor is arranged on the surface of the heat exchanger. The outdoor environment humidity is obtained by: sending a humidity acquisition instruction to the humidity sensor to trigger the humidity sensor to feed back the detected humidity.

[0065] Optionally, after triggering the flow valve to open, the method further comprises: monitoring the frost condition of the heat exchanger in real time, and controlling the regulating valve and the flow valve to close when the heat exchanger is not frosted.

[0066] Optionally, after triggering the flow valve to open, the method further comprises: determining an interval time according to the frost thickness, monitoring the frost condition of the heat exchanger in real time after the interval time is reached, and controlling the regulating valve and the flow valve to close in the case that the heat exchanger is not frosted. Since the greater the frost thickness is, the longer the defrosting time is generally, in the case that it is known that the frost thickness on the heat exchanger is large, the frost thickness does not need to be detected. Therefore, by determining the interval time according to the frost thickness and monitoring the frost condition of the heat exchanger only after the interval time is reached, unnecessary detection steps can be reduced, thereby saving energy.

[0067] In combination with Figure 4 As shown in the drawings, the embodiment of the present disclosure provides a method for defrosting, applied to an air conditioner, the air conditioner comprising a compressor, a first heat exchange device connected to the compressor through a regulating valve, a second heat exchange device connected to the first heat exchange device through a pipeline, the second heat exchange device being arranged on a heat exchanger, and the second heat exchange device storing an intermediate medium, and the second heat exchange device being provided with a flow valve, the method comprising:

[0068] Step S401, an electronic device acquires a frost condition of a heat exchanger, the frost condition being used to represent whether the heat exchanger is frosted or not.

[0069] Step S402, in the case that the heat exchanger is frosted, the electronic device determines a running state of the air conditioner, wherein the running state represents whether the air conditioner is running or not.

[0070] Step S403, in the case that the air conditioner is running, the electronic device triggers the regulating valve to open, so that the refrigerant flows from the compressor into the first heat exchange device to exchange heat with the intermediate medium in the second heat exchange device.

[0071] Step S404, the electronic device acquires a frost thickness of the heat exchanger.

[0072] Step S405, the electronic device determines a target temperature and an interval time according to the frost thickness.

[0073] Step S406, in the case that the temperature of the heat-exchanged intermediate medium is greater than the target temperature, the electronic device triggers the flow valve to open.

[0074] Step S407, after the interval time is reached, the electronic device monitors the frost condition of the heat exchanger in real time.

[0075] Step S408, in the case that the heat exchanger is not frosted, the electronic device controls the regulating valve and the flow valve to close.

[0076] The method for defrosting provided by the embodiment of the present disclosure can directly trigger the regulating valve to open when the air conditioner is running and defrosting is needed, so that the refrigerant flows from the compressor to the first heat exchange device to exchange heat with the intermediate medium in the second heat exchange device. Since the second heat exchange device is arranged on the heat exchanger and the refrigerant flowing from the compressor is a high-temperature and high-pressure gas, the temperature of the intermediate medium in the second heat exchange device will rise when the refrigerant flows from the compressor to the first heat exchange device, thereby achieving the effect of heating and defrosting the surface of the heat exchanger. In this process, even if the air conditioner is running in a heating state, it is not necessary to switch the air conditioner to a cooling state to achieve the defrosting effect, thereby reducing the fluctuation of the indoor temperature and improving the user experience of using the air conditioner. Moreover, the frost thickness of the heat exchanger is obtained, and the target temperature is determined according to the frost thickness. Then, the flow valve is triggered to open when the temperature of the heat-exchanged intermediate medium is greater than the target temperature. The part of the intermediate medium can be heated to reach the target temperature more quickly. At the same time, the surface of the heat exchanger can be heated by the intermediate medium reaching the target temperature to melt the frost more quickly.

[0077] Optionally, the interval time is determined according to the frost thickness, including: matching the interval time corresponding to the frost thickness in a preset third database. The third database stores the corresponding relationship between the frost thickness and the interval time.

[0078] In some embodiments, when the frost thickness is less than or equal to 1 mm, the interval time corresponding to the frost thickness is 20 minutes. When the frost thickness is greater than 1 mm and less than or equal to 5 mm, the interval time corresponding to the frost thickness is 30 minutes. When the frost thickness is greater than 5 mm, the interval time corresponding to the frost thickness is 30 minutes.

The running state represents whether the air conditioner is running or not. The control module 503 is configured to trigger the regulating valve to open when the air conditioner is running, so that the refrigerant flows from the compressor to the first heat exchange device to exchange heat with the intermediate medium in the second heat exchange device.

[0080] The device for defrosting provided by the embodiment of the present disclosure can directly trigger the regulating valve to open when the air conditioner is running and defrosting is needed, so that the refrigerant flows from the compressor to the first heat exchange device to exchange heat with the intermediate medium in the second heat exchange device. Since the second heat exchange device is arranged on the heat exchanger and the refrigerant flowing from the compressor is a high-temperature and high-pressure gas, the temperature of the intermediate medium in the second heat exchange device will rise when the refrigerant flows from the compressor to the first heat exchange device, thereby achieving the effect of heating and defrosting the surface of the heat exchanger. In this process, the defrosting effect can be achieved without switching the running state of the air conditioner, thereby reducing the fluctuation of the indoor temperature and improving the user experience of using the air conditioner.

[0081] Optionally, the second heat exchange device is provided with a flow valve, and the device for defrosting further comprises a second acquisition module and a second determination module. The second acquisition module is configured to acquire the frost thickness of the heat exchanger.

Since the second heat exchange device is arranged on the heat exchanger, and the refrigerant flowing out of the compressor is a high-temperature and high-pressure gas, in the case that the refrigerant flows from the compressor to the first heat exchange device, the temperature of the intermediate medium in the second heat exchange device will rise, thereby achieving the effect of heating and defrosting the surface of the heat exchanger.
