[0033] In the embodiment of the present disclosure, the execution subject of the defrosting method is an electronic device, and the electronic device is a server, a computer, 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 for communication via the Internet. The air conditioner includes a compressor, a first heat exchange device connected to the compressor via a regulating valve, a second heat exchange device connected to the first heat exchange device via a pipeline, the second heat exchange device is arranged on the heat exchanger, and the intermediate medium is stored in the second heat exchange device. The server or 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 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 an intermediate medium is stored in the second heat exchange device. The air conditioner controls the opening or closing of the regulating valve to heat the heat exchanger to defrost the heat exchanger.

[0036] Combination Figure 1 As shown, an embodiment of the present disclosure provides an air conditioner, comprising 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 and the second heat exchange device are connected through a pipeline, the second heat exchange device is arranged on the heat exchanger, and an intermediate medium is stored in the second heat exchange device.

[0037] Combination Figure 2 As shown, an embodiment of the present disclosure provides a method for defrosting, which is applied to an air conditioner, wherein the air conditioner includes a compressor, a first heat exchange device connected to the compressor through a regulating valve, and a second heat exchange device connected to the first heat exchange device through a pipeline, wherein the second heat exchange device is arranged on a heat exchanger, and an intermediate medium is stored in the second heat exchange device, and the method includes:

[0038] Step S201: the electronic device obtains the frosting condition of the heat exchanger, where the frosting condition is used to indicate whether the heat exchanger is frosted or not.

[0039] Step S202, when the heat exchanger is frosted, the electronic device determines the operating state of the air conditioner, wherein the operating state indicates whether the air conditioner is operating or not operating;

[0040] Step S203: When 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.

[0041] The defrosting method provided by the embodiment of the present disclosure is adopted. When the air conditioner is running and defrosting is required, the regulating valve is directly triggered 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. 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, when 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 accordingly, 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 operating state of the air conditioner, thereby reducing the fluctuation of the indoor temperature and improving the user's experience of using the air conditioner.

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

[0043] Optionally, a flow valve is provided on the second heat exchange device, and after the regulating valve is triggered to open, the method further includes: obtaining the frost thickness of the heat exchanger; determining the target temperature according to the frost thickness; and triggering the flow valve to open when the temperature of the intermediate medium after heat exchange is greater than the target temperature. In this way, part of the intermediate medium can be heated intensively, so that the intermediate medium reaches the target temperature more quickly. At the same time, by using the intermediate medium that reaches the target temperature to heat the surface of the heat exchanger, the frost can be defrosted more quickly.

[0044] Combination Figure 3 As shown, an embodiment of the present disclosure provides a method for defrosting, which is applied to an air conditioner. The air conditioner includes a compressor, a first heat exchange device connected to the compressor through a regulating valve, and 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 an intermediate medium is stored in the second heat exchange device. A flow valve is arranged on the second heat exchange device. The method includes:

[0045] Step S301: the electronic device obtains the frosting condition of the heat exchanger, where the frosting condition is used to indicate whether the heat exchanger is frosted or not.

[0046] Step S302: When the heat exchanger is frosted, the electronic device determines the operating state of the air conditioner, wherein the operating state indicates whether the air conditioner is operating or not operating.

[0047] Step S303: When 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.

[0048] Step S304: the electronic device obtains the frost thickness of the heat exchanger.

[0049] Step S305: the electronic device determines a target temperature according to the frost thickness.

[0050] Step S306: When the temperature of the intermediate medium after heat exchange is greater than the target temperature, the electronic device triggers the flow valve to open.

[0051] The defrosting method provided by the embodiment of the present disclosure is adopted. When the air conditioner is running and defrosting is required, the regulating valve is directly triggered 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. 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, when 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 accordingly, 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 the heating state, it is not necessary to switch the air conditioner to the cooling state to achieve the defrosting effect, thereby reducing the fluctuation of the indoor temperature and improving the user's experience of using the air conditioner. In addition, by obtaining the frost thickness of the heat exchanger, the target temperature is determined according to the frost thickness. Then, when the temperature of the intermediate medium after heat exchange is greater than the target temperature, the flow valve is triggered to open. Part of the intermediate medium can be heated intensively, so that the part of the intermediate medium reaches the target temperature more quickly. At the same time, by using the intermediate medium that reaches the target temperature to heat the surface of the heat exchanger, the frost can be defrosted more quickly.

[0052] Further, determining the target temperature according to the frosting thickness includes: matching the target temperature corresponding to the frosting thickness in a preset first database. The first database stores the corresponding relationship between the frosting thickness and the target temperature. The higher the target temperature, the greater the corresponding frosting thickness.

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

[0054] Optionally, triggering the flow valve to open includes: determining a target valve opening according to the thickness of the frost. The flow valve is triggered to open according to the target valve opening. Since the opening 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 heat exchanger by the second heat exchange device. Therefore, by determining the target valve opening according to the thickness of the frost, the target valve opening can be changed with the change of the frost thickness, so that defrosting can be completed more quickly.

[0055] Further, determining the target valve opening according to the frosting thickness includes: matching the target valve opening corresponding to the frosting thickness in a preset second database. The second database stores the corresponding relationship between the frosting thickness and the target valve opening.

[0056] In some embodiments, when the frosting thickness is less than or equal to 1 mm, the target valve opening corresponding to the frosting thickness is half open. When the frosting thickness is greater than 1 mm, the target valve opening corresponding to the frosting thickness is fully open.

[0057] Optionally, obtaining the frosting thickness of the heat exchanger includes: obtaining image information of the heat exchanger and inputting the image information into a preset frosting thickness recognition model to obtain the frosting thickness of the heat exchanger.

[0058] Optionally, a frost thickness detection device is provided on the heat exchanger, and obtaining the frost thickness on the heat exchanger includes: sending a thickness detection instruction to the frost thickness detection device, triggering the frost thickness detection device to feed back the detected frost thickness.

[0059] Optionally, obtaining the frosting condition of the heat exchanger includes: obtaining the frosting condition of the heat exchanger when the outdoor ambient temperature is lower than a preset temperature and the outdoor ambient humidity is lower than a preset humidity.

[0060] The heat exchanger is arranged in the outdoor unit of the air conditioner. When the air conditioner is running in the heating mode, the outdoor heat exchanger of the air conditioner absorbs the heat in the air and reduces the surface temperature of the outdoor heat exchanger. At this time, if the outdoor ambient temperature is low and the outdoor ambient humidity is high, then frost is likely to appear on the surface of the outdoor heat exchanger. Therefore, by obtaining the frost condition of the heat exchanger only when the outdoor ambient temperature is lower than the preset temperature and the outdoor ambient humidity is lower than the preset humidity, unnecessary detection steps can be reduced.

[0061] Optionally, after determining the operating state of the air conditioner, the method further includes: when the air conditioner is not in operation, controlling the air conditioner to operate in a cooling mode, so that the high-temperature and high-pressure refrigerant discharged from 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 ambient temperature is the temperature of the area where the air conditioner outdoor unit is located. The outdoor ambient humidity is the humidity of the area where the air conditioner outdoor unit is located.

[0063] Furthermore, a temperature sensor is provided on the surface of the heat exchanger. The outdoor environment temperature is obtained in the following manner: a temperature acquisition instruction is sent to the temperature sensor, and the temperature sensor is triggered to feedback the detected temperature.

[0064] Furthermore, a humidity sensor is provided on the surface of the heat exchanger to obtain the outdoor environment humidity in the following manner: a humidity acquisition instruction is sent to the humidity sensor, and the humidity sensor is triggered to feedback the detected humidity.

[0065] Optionally, after the flow valve is triggered to open, the method further includes: real-time monitoring of the frosting condition of the heat exchanger, and when the heat exchanger is not frosted, controlling the regulating valve and the flow valve to close.

[0066] Optionally, after the flow valve is triggered to open, it also includes: determining an interval time according to the frosting thickness, monitoring the frosting 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 when the heat exchanger is not frosted. Since the greater the frosting thickness, the longer the corresponding defrosting time is usually, therefore, if it is known that the frosting thickness on the heat exchanger is large, it is not necessary to detect the frosting thickness. Therefore, by determining the interval time according to the frosting thickness and monitoring the frosting condition of the heat exchanger after the interval time is reached, unnecessary detection steps can be reduced, thereby saving energy.

[0067] Combination Figure 4 As shown, an embodiment of the present disclosure provides a method for defrosting, which is applied to an air conditioner. The air conditioner includes a compressor, a first heat exchange device connected to the compressor through a regulating valve, and 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 an intermediate medium is stored in the second heat exchange device. A flow valve is arranged on the second heat exchange device. The method includes:

[0068] Step S401: the electronic device obtains the frosting condition of the heat exchanger, where the frosting condition is used to indicate whether the heat exchanger is frosted or not.

[0069] Step S402, when the heat exchanger is frosted, the electronic device determines the operating state of the air conditioner, wherein the operating state indicates whether the air conditioner is operating or not operating;

[0070] Step S403: When 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 obtains the frost thickness of the heat exchanger.

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

[0073] Step S406: When the temperature of the intermediate medium after heat exchange 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 frosting condition of the heat exchanger in real time.

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

[0076] The defrosting method provided by the embodiment of the present disclosure is adopted. When the air conditioner is running and defrosting is required, the regulating valve is directly triggered 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. 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, when 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 accordingly, 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 the heating state, it is not necessary to switch the air conditioner to the cooling state to achieve the defrosting effect, thereby reducing the fluctuation of the indoor temperature and improving the user's experience of using the air conditioner. In addition, by obtaining the frost thickness of the heat exchanger, the target temperature is determined according to the frost thickness. Then, when the temperature of the intermediate medium after heat exchange is greater than the target temperature, the flow valve is triggered to open. Part of the intermediate medium can be heated intensively, so that the part of the intermediate medium reaches the target temperature more quickly. At the same time, by using the intermediate medium that reaches the target temperature to heat the surface of the heat exchanger, the frost can be defrosted more quickly.

[0077] Optionally, determining the interval time according to the frosting thickness includes: matching the interval time corresponding to the frosting thickness in a preset third database. The third database stores the corresponding relationship between the frosting thickness and the interval time.

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

The frosting condition is used to characterize whether the heat exchanger is frosted or not frosted. The first determination module 502 is configured to determine the operating state of the air conditioner when the heat exchanger is frosted. Among them, the operating state characterizes whether the air conditioner is running or not running. The control module 503 is configured to trigger the opening of the regulating valve when the air conditioner is running, 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.

[0080] The defrosting device provided by the embodiment of the present disclosure is used. When the air conditioner is running and defrosting is required, the regulating valve is directly triggered 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. 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, when 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 accordingly, 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 operating state of the air conditioner, thereby reducing the fluctuation of the indoor temperature and improving the user's experience of using the air conditioner.

[0081] Optionally, a flow valve is provided on the second heat exchange device, and the defrosting device 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.
