In the prior art, in order to prevent the water system pipes from freezing, the heat pump can be started for heating when the ambient temperature is low to increase the water temperature in the pipe to achieve the purpose of anti-freezing. However, heating will cause the temperature control equipment to be frequently started, which consumes a lot of electricity. It is necessary to provide a more convenient and lower energy consumption anti-freezing method. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Heat pump units are used in temperature control equipment such as water heating and air conditioning. Heat pump units are devices that transfer heat from low-temperature heat sources to high-temperature heat sources by circulating refrigerant in components such as evaporators, compressors, condensers and expansion valves. For example, when the temperature control equipment is a heat pump air conditioner, it can be used for cooling in summer and heating in winter. In cooling mode, the heat pump air conditioner can transfer indoor heat to outdoor, and in heating mode, the heat pump air conditioner transfers outdoor heat to indoor, providing heating even in cold weather. The water system pipes that come with the heat pump unit play a vital role in its operation, and are mainly responsible for the transfer and circulation of heat. They can also play a role in cold and heat source exchange, temperature stabilization and energy efficiency optimization. The circulating medium in the water system pipes can be liquids such as water or antifreeze. When the temperature is low, such as in winter, the liquid in the pipeline is easy to freeze, which may cause the water system pipeline of the heat pump unit to rupture and generate reliability risks. The embodiment of the present application provides a heat pump antifreeze device, which can be applied to the temperature control equipment to prevent the water system pipeline of the heat pump unit from freezing. The heat pump antifreeze method provided in the embodiment of the present application can be implemented by relying on a computer program and can be run on a heat pump antifreeze device based on the von Neumann system. The computer program can be integrated in the application or run as an independent tool application. The heat pump antifreeze device can be a temperature control device or a module in the temperature control device for implementing the heat pump antifreeze method.

[0025] Please also see Figure 1, a system architecture diagram of a temperature control device is provided for an embodiment of the present application. The temperature control device can be used to control the temperature in a target area, wherein the target area can be a house, a room, etc. The temperature control device can include a heat pump unit, a pipe outside the target area, and a pipe inside the target area. The pipe outside the target area and the pipe inside the target area are water system pipes for heat transfer and circulation for the target area, wherein the heat pump unit and the pipe outside the target area are arranged outside the target area, the pipe inside the target area is arranged inside the target area, and the pipe outside the target area connects the heat pump unit and the pipe inside the target area, thereby realizing heat transfer and circulation. For example, if the temperature control device is an air conditioner, and the target area is the room where the user lives, the heat pump unit can be an outdoor air conditioner outdoor unit, the pipe outside the target area is an outdoor air conditioning pipe, and the pipe inside the target area is an indoor air conditioning pipe. If the temperature control device is water heating, and the target area is the room where the user lives, the outdoor heat pump unit is used to heat the liquid in the pipe, the pipe inside the target area is a water pipe laid in the room for heating, and the pipe outside the target area is used to connect the heat pump unit and the pipe inside the target area. The temperature control device also includes a regional pipeline valve, which is used to control the flow of liquid between the pipeline in the target area and the pipeline outside the target area. The regional pipeline valve can be a solenoid valve. The regional pipeline valve can help the temperature control device and the user to adjust the water flow in the water system pipeline as needed, thereby controlling the heat distribution and system operation status, thereby avoiding unnecessary energy consumption and improving the energy efficiency of the system. When the temperature control device is in standby mode, in order to avoid heat loss caused by the flow of liquid in the pipeline, the regional pipeline valve can be in a closed state, so that the liquid between the pipeline in the target area and the pipeline outside the target area does not flow, wherein the standby state is a state where the temperature control device is powered on but has not been started by the user.

[0026] The target area is often the room where the user lives and works, usually an indoor scene, so the temperature in the target area will be higher than the temperature outside the target area, so the water temperature in the pipes in the target area will be higher than the water temperature in the pipes outside the target area, so the heat pump anti-freeze device can switch the temperature control equipment from standby mode to anti-freeze mode when the temperature is low and liquid in the water system pipes is prone to freezing. In the anti-freeze mode, the heat pump anti-freeze device can perform anti-freeze operations on the temperature control equipment, for example, it can open the regional pipe valve to allow liquid to circulate between the pipes in the target area and the pipes outside the target area, thereby balancing the water temperature in the water system pipes, thereby achieving the purpose of anti-freezing.

[0027] The heat pump anti-freezing method provided in the present application is described in detail below in conjunction with specific embodiments.

[0028] See also Figure 2 , which is a schematic diagram of a heat pump antifreeze method according to an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101-S103.

[0029] S101, when the temperature control device is in a standby state, the ambient temperature and the pipe water temperature are obtained.

[0030] Specifically, when the temperature control equipment is in standby mode, the heat pump anti-freeze device can continuously obtain the ambient temperature and the pipe water temperature. The ambient temperature can be the ambient temperature of the heat pump unit of the temperature control equipment and the pipe outside the target area, that is, the ambient temperature outside the target area. The pipe water temperature can be the water temperature in the water system pipe of the heat pump unit. The ambient temperature and the pipe water temperature can be used to determine whether the pipe is at risk of freezing.

[0031] S102: If the ambient temperature is greater than the first preset ambient temperature and the pipeline water temperature is less than the first preset water temperature, switch to the anti-freezing state and open the regional pipeline valve.

[0032] Specifically, if the heat pump anti-freeze device detects that the ambient temperature is greater than the first preset ambient temperature, and the pipe water temperature is less than the preset water temperature, it can be determined that the water system pipe is in a state where there is a risk of freezing and anti-freeze treatment is required. The heat pump anti-freeze device can control the temperature control device to switch from the standby state to the anti-freeze state. In the anti-freeze state, the heat pump anti-freeze device can use water circulation, heat pump units or auxiliary heat sources to avoid pipe freezing according to the specific situation of the temperature control device. Since the temperature in the target area will be higher than the temperature outside the target area, the water temperature in the pipe in the target area will also be higher than the water temperature in the pipe outside the target area. Therefore, the heat pump anti-freeze device can open the regional pipe valve to allow liquid to circulate between the pipe in the target area and the pipe outside the target area, and use the water temperature in the pipe in the target area to balance the water temperature in the pipe outside the target area.

[0033] Among them, the first preset ambient temperature and the first preset water temperature are used to determine whether the water system pipeline is in a state of freezing risk. It can be the initial setting of the heat pump anti-freeze device, and can also be set by the user or relevant staff according to the local environment and needs. For example, the first preset ambient temperature can be 3°C, and the first preset water temperature can be 4°C.

[0034] S103: If the pipeline water temperature is greater than the first standby water temperature after the first operating time, the regional pipeline valve is closed and switched back to the standby state.

[0035] Specifically, after the first operating time after the regional pipeline valve is opened, the heat pump anti-freeze device can detect the pipeline water temperature again. If the pipeline water temperature is greater than the first standby water temperature after the first operating time, it is determined that the water system pipeline is not at risk of freezing, and the regional pipeline valve can be closed and the temperature control device can be switched from the anti-freeze state back to the standby state. Anti-freeze treatment is performed by balancing the water temperature inside and outside the target area to avoid frequent starting of the heat pump unit of the temperature control device for heating. The first standby water temperature can be the initial setting of the heat pump anti-freeze device, and can also be set by the user or relevant staff according to the local environment and needs. For example, the first standby water temperature can be 8°C.

[0036] In an embodiment of the present application, when the temperature control device is in standby mode, the ambient temperature and the pipe water temperature are obtained. If the ambient temperature is greater than the first preset ambient temperature, and the pipe water temperature is less than the first preset water temperature, the regional pipe valve is opened, and the regional pipe valve is used to control the liquid flow between the pipe in the target area and the pipe outside the target area. If the pipe water temperature is greater than the first standby water temperature after the first operating time, the regional pipe valve is closed and switched back to the standby mode. The ambient temperature and the pipe water temperature are used to determine whether there is a risk of freezing. If there is a risk of freezing, liquid is circulated in the pipes inside and outside the target area to increase the pipe water temperature, thereby avoiding frequent heating startup of the equipment and making anti-freezing more convenient and less energy-consuming.

[0037] See also Figure 3 , which is a schematic diagram of a heat pump antifreeze method according to an embodiment of the present application. Figure 3 As shown, the method of the embodiment of the present application may include the following steps S201-S209.

[0038] S201, when the temperature control device is in a standby state, obtain the ambient temperature and the pipe water temperature.

[0039] Specifically, when the temperature control equipment is in standby mode, the heat pump anti-freeze device can continuously obtain the ambient temperature and the pipe water temperature. The ambient temperature can be the ambient temperature of the heat pump unit of the temperature control equipment and the pipe outside the target area, that is, the ambient temperature outside the target area. The pipe water temperature can be the water temperature in the water system pipe of the heat pump unit. The ambient temperature and the pipe water temperature can be used to determine whether the pipe is at risk of freezing.

[0040] Optionally, the heat pump anti-freezing device can obtain the ambient temperature outside the target area. For example, a temperature sensor can be installed at the heat pump unit to obtain the ambient temperature according to the temperature sensor.

[0041] In order to further improve the accuracy of the pipe water temperature, the heat pump anti-freezing device can obtain the inlet and outlet water temperatures between the heat pump unit and the pipe outside the target area. Since the water system pipe is circulated, the pipe outside the target area and the heat pump unit are connected by an inlet pipe and an outlet pipe. The pipe outside the target area inputs the liquid into the heat pump unit through the inlet pipe. The heat pump unit can heat or cool the liquid. Then the heat pump unit can output the liquid to the pipe outside the target area through the outlet pipe. Therefore, the inlet water temperature can be the water temperature at the inlet pipe, and the outlet water temperature is the water temperature at the outlet pipe. Since the heat pump unit can include an auxiliary heat source and a compressor, the main function of the compressor is to compress the refrigerant gas to increase its pressure and temperature. After absorbing heat, the refrigerant becomes a low-temperature and low-pressure gas and is then sucked and compressed by the compressor, so that its temperature and pressure increase, and promote the transfer of heat from the low-temperature heat source to the high-temperature heat source, thereby achieving the effect of heating or cooling. The auxiliary heat source can be used to heat the liquid in the water system pipeline, and can also be used to assist the compressor to heat when the heating effect of the compressor is not enough. It is understandable that the power and heating effect of the auxiliary heat source are less than that of the compressor. The heat pump anti-freeze device can also obtain the heat source outlet temperature at the auxiliary heat source. Then, the minimum temperature among the water inlet temperature, water outlet temperature and heat source outlet temperature is obtained, and the minimum temperature is determined as the pipeline water temperature, thereby improving the accuracy of the pipeline water temperature and avoiding missed detection and pipeline freezing.

[0042] S202: If the ambient temperature is greater than the first preset ambient temperature and the pipeline water temperature is less than the first preset water temperature, switch to the anti-freeze state and open the regional pipeline valve.

[0043] Specifically, if the heat pump antifreeze device detects that the ambient temperature is greater than the first preset ambient temperature and the pipe water temperature is less than the preset water temperature, it can be determined that the water system pipe is in a state where there is a risk of freezing and antifreeze treatment is required. The heat pump antifreeze device can control the temperature control device to switch from the standby state to the antifreeze state. In the antifreeze state, the heat pump antifreeze device can use water circulation, heat pump units or auxiliary heat sources to avoid pipe freezing according to the specific situation of the temperature control device. Since the temperature in the target area will be higher than the temperature outside the target area, the water temperature in the pipe in the target area will also be higher than the water temperature in the pipe outside the target area. Therefore, the heat pump antifreeze device can open the regional pipe valve to allow the liquid to flow between the pipe in the target area and the pipe outside the target area, and use the water temperature in the pipe in the target area to balance the water temperature in the pipe outside the target area. Among them, the first preset ambient temperature and the first preset water temperature are used to determine whether the water system pipe is in a state where there is a risk of freezing. They can be the initial settings of the heat pump antifreeze device, or they can be set by the user or relevant staff according to the local environment and needs. For example, the first preset ambient temperature can be 3°C, and the first preset water temperature can be 4°C.

[0044] Optionally, if the heat pump antifreeze device detects that the ambient temperature is lower than the second preset ambient temperature, and the pipe water temperature is lower than the second preset water temperature, it can also be determined that the water system pipe is in a state where there is a risk of freezing, and antifreeze treatment is required. The heat pump antifreeze device can open the regional pipe valve to allow liquid to circulate between the pipe in the target area and the pipe outside the target area. Among them, the first preset ambient temperature is greater than or equal to the second preset ambient temperature, and the first preset water temperature is greater than the second preset water temperature. For example, if the first preset ambient temperature can be 3°C and the first preset water temperature can be 4°C, then the second preset ambient temperature can also be 3°C and the second preset water temperature can be 2°C. It can be understood that when the ambient temperature is high and the pipe water temperature is low, there may be abnormal problems such as local temperature reduction, and there may be a risk of freezing. However, when the ambient temperature is low, the pipe water temperature will be lower under normal circumstances. Therefore, setting the second preset water temperature lower than the first preset water temperature can prevent the wrong judgment of the risk of freezing, further avoid frequent startup of the temperature control equipment, and achieve the purpose of reducing energy consumption.

[0045] S203, determining whether the pipeline water temperature after the first operating time is greater than the first standby water temperature.

[0046] Specifically, after the first operation time after the regional pipeline valve is opened, the heat pump anti-freezing device can detect the pipeline water temperature again, and determine whether the pipeline water temperature after the first operation time is greater than the first standby water temperature. If so, step S204 is executed, otherwise, step S205 is executed. The first standby water temperature and the first operation time can be the initial settings of the heat pump anti-freezing device, and can also be set by the user or relevant staff according to the local environment and needs. For example, the first standby water temperature can be 8°C, and the first operation time can be 5 minutes.

[0047] S204, close the regional pipeline valve and switch back to standby mode.

[0048] Specifically, if the water temperature in the pipeline is greater than the first standby water temperature after the first operating time, it is determined that the water system pipeline is not at risk of freezing, and the regional pipeline valve can be closed and the temperature control device can be switched from the anti-freeze state back to the standby state. Anti-freeze treatment is performed by balancing the water temperature inside and outside the target area, avoiding frequent starting of the heat pump unit of the temperature control device for heating.

[0049] It is understandable that, after the temperature control device is switched back to the standby state, the heat pump anti-freezing device can continue to execute step S201.

[0050] S205, starting the auxiliary heat source for heating.

[0051] Specifically, if the pipe water temperature is lower than the first standby water temperature after the first operation time, it means that the water temperature inside and outside the balanced target area can no longer prevent freezing, and the water system pipes are still at risk of freezing. The heat pump anti-freezing device can start the auxiliary heat source for heating to increase the liquid temperature in the water system pipes. Since the heating temperature required for anti-freezing is much lower than the temperature required for heating the target area, starting the compressor for heating at this time will waste energy, and the power of the auxiliary heat source is lower than that of the compressor, the auxiliary heat source can be started first for heating to further reduce energy consumption.

[0052] Optionally, there is often a four-way valve in the temperature control device. The four-way valve is an electromagnetic control valve used in the heat pump unit. Its main function is to switch between cooling mode, heating mode or defrosting mode by changing the flow direction of the refrigerant. In order to reduce the pressure shock when the four-way valve is switched and avoid damage to the four-way valve, the heat pump anti-freeze device can set the four-way valve to switch after the compressor stops for a preset time threshold, so that the four-way valve switches under the state of high and low pressure balance, thereby reducing the wear or damage of the four-way valve caused by excessive pressure difference and extending the service life of the four-way valve. Therefore, when it is detected that the pipeline water temperature is greater than the first standby water temperature after the first operating time, the heat pump anti-freeze device can obtain the shutdown time of the compressor. If the pipeline water temperature is less than the first standby water temperature after the first operating time, and the shutdown time is greater than the preset time threshold, the auxiliary heat source is started, thereby avoiding the situation where the four-way valve cannot turn normally and the heating cannot be turned on normally, further improving the reliability of the heat pump anti-freeze.

[0053] S206, determining whether the pipeline water temperature during the second operating time is greater than the second standby water temperature.

[0054] Specifically, during the second operation time after the auxiliary heat source is turned on, the heat pump antifreeze device can continuously obtain the pipe water temperature and determine whether the pipe water temperature is greater than the second standby water temperature. If so, step S207 is executed, otherwise, step S208 is executed. The second standby water temperature and the second operation time can be the initial settings of the heat pump antifreeze device, or can be set by the user or relevant staff according to the local environment and needs. For example, the second standby water temperature can be 10°C and the second operation time can be 5 minutes.

[0055] S207, close the regional pipeline valves and auxiliary heat sources, and switch back to standby mode.

[0056] Specifically, if the water temperature in the pipeline during the second operating time is greater than the second standby water temperature, it is determined that the water system pipeline is not at risk of freezing. The regional pipeline valve and the auxiliary heat source can be closed, and the temperature control equipment can be switched from the anti-freeze state back to the standby state. Anti-freeze treatment is performed through the auxiliary heat source to avoid energy loss caused by starting the compressor.

[0057] S208, turning off the auxiliary heat source and starting the compressor for heating.

[0058] Specifically, if the water temperature in the pipeline is lower than the second standby water temperature, and the operating time of the auxiliary heat source is greater than the second operating time, it means that the auxiliary heat source cannot be used for heating to prevent freezing, and the water system pipeline is still at risk of freezing, indicating that the power of the auxiliary heat source is insufficient to prevent freezing, or the auxiliary heat source has partial or complete failure. If the auxiliary heat source continues to be used, incomplete freeze dissolution or insufficient antifreeze capacity may occur, resulting in rupture of the water system pipeline of the unit. The heat pump anti-freeze device can turn off the auxiliary heat source and start the compressor for heating to achieve the purpose of anti-freezing.

[0059] Optionally, if the water temperature in the pipeline is lower than the second standby water temperature, and the operating time of the auxiliary heat source is greater than the second operating time, the heat pump anti-freeze device can obtain the operating power of the auxiliary heat source during the second operating time. If the operating power is lower than the standard power of the auxiliary heat source, it can be determined that the auxiliary heat source has failed. The heat pump anti-freeze device can output an auxiliary heat source failure warning to the user or relevant staff, so as to facilitate the user or relevant staff to inspect and repair the auxiliary heat source, and further ensure the stability of the anti-freeze capability.

[0060] S209: If the pipeline water temperature is greater than the third standby water temperature, close the regional pipeline valve and the compressor, and switch back to the standby state.

[0061] Specifically, after the compressor is turned on, the heat pump anti-freeze device can continuously obtain the pipe water temperature. If the pipe water temperature is greater than the third standby water temperature, it is determined that the water system pipe is not at risk of freezing, and the regional pipe valve and compressor can be closed, and the temperature control device is switched from the anti-freeze state back to the standby state, and the compressor is combined with the anti-freeze treatment to avoid the situation where the unit water system pipe breaks due to insufficient anti-freeze capacity of the auxiliary heat source. Among them, the third standby water temperature can be the initial setting of the heat pump anti-freeze device, and can also be set by the user or relevant staff according to the local environment and needs. For example, the third standby water temperature can be 15°C.

[0062] Optionally, the first standby water temperature, the second standby water temperature and the third standby water temperature are all used to determine whether the water system pipes are at risk of freezing. The first standby water temperature, the second standby water temperature and the third standby water temperature may be the same or different. Since the power and energy consumption of the compressor are greater than the power and energy consumption of the auxiliary heat source, the third standby water temperature may be greater than the second standby water temperature. The energy consumption of starting the auxiliary heat source is also greater than the energy consumption of opening the regional pipeline valve, so the second standby water temperature may be greater than the first standby water temperature.

[0063] Optionally, since the compressor has a large power, continuously turning on the compressor will consume a lot of energy, so the heat pump anti-freeze device can control the time the compressor is used for anti-freeze treatment. If the compressor running time is greater than the third running time, the regional pipeline valve and the compressor are closed, and switched back to standby mode.

[0064] In the embodiment of the present application, when the temperature control device is in the standby state, the ambient temperature and the pipe water temperature are obtained. The pipe water temperature is the minimum temperature among the water inlet temperature, the water outlet temperature and the heat source outlet temperature, which further improves the accuracy of the pipe water temperature and avoids missing detection and causing pipe freezing. If the ambient temperature is greater than the first preset ambient temperature, and the pipe water temperature is less than the first preset water temperature, it is switched to the anti-freezing state and the regional pipe valve is opened. If the heat pump anti-freezing device detects that the ambient temperature is less than the second preset ambient temperature, and the pipe water temperature is less than the second preset water temperature, it is switched to the anti-freezing state and the regional pipe valve is opened. The second preset water temperature is lower than the first preset water temperature, which can prevent the wrong judgment of the existence of freezing risk, further avoid the frequent start-up of the temperature control device, and achieve the purpose of reducing energy consumption. If the pipe water temperature is greater than the first standby water temperature after the first running time, the regional pipe valve is closed and switched back to the standby state. It is judged whether there is a freezing risk by the ambient temperature and the pipe water temperature. If there is a freezing risk, the pipes inside and outside the target area are circulated with liquid to increase the pipe water temperature, which avoids the frequent start-up of the equipment for heating, making anti-freezing more convenient and lower energy consumption. If the pipeline water temperature is lower than the first standby water temperature after the first operating time, the auxiliary heat source is started for heating, and anti-freezing treatment is performed through the auxiliary heat source to avoid energy loss caused by starting the compressor. And the auxiliary heat source can be started only when the compressor shutdown time is longer than the preset time threshold, thereby avoiding the situation where the four-way valve cannot turn normally and the heating cannot be turned on normally, further improving the reliability of the heat pump anti-freezing. If the pipeline water temperature is higher than the second standby water temperature during the second operating time, the regional pipeline valve and the auxiliary heat source are closed, and the system is switched back to the standby state. If the pipeline water temperature is lower than the second standby water temperature, the auxiliary heat source is turned off, and the compressor is started for heating. If the pipeline water temperature is higher than the third standby water temperature, the regional pipeline valve and the compressor are closed and switched back to the standby state. The compressor is combined with the anti-freezing treatment to avoid the situation where the unit water system pipeline is broken due to insufficient anti-freezing capacity of the auxiliary heat source.

[0066] See also Figure 4 , which shows a schematic diagram of the structure of a heat pump antifreeze device provided by an exemplary embodiment of the present application. The heat pump antifreeze device can be implemented as all or part of the device through software, hardware or a combination of both. The device 1 includes a temperature acquisition unit 11, a first valve control unit 12 and a second valve control unit 13.

[0067] The temperature acquisition unit 11 is used to acquire the ambient temperature and the pipe water temperature when the temperature control device is in a standby state;

[0068] A first valve control unit 12, configured to switch to an anti-freezing state and open a regional pipeline valve when the ambient temperature is greater than a first preset ambient temperature and the pipeline water temperature is less than the first preset water temperature, wherein the regional pipeline valve is configured to control the flow of liquid between the pipeline in the target area and the pipeline outside the target area;

[0069] The second valve control unit 13 is used to close the regional pipeline valve and switch back to the standby state if the pipeline water temperature is greater than the first standby water temperature after the first operating time.

[0070] In this embodiment, when the temperature control device is in standby mode, the ambient temperature and the pipe water temperature are obtained. If the ambient temperature is greater than the first preset ambient temperature and the pipe water temperature is less than the first preset water temperature, the device switches to the anti-freezing mode and opens the regional pipe valve, which is used to control the liquid flow between the pipe in the target area and the pipe outside the target area. If the pipe water temperature is greater than the first standby water temperature after the first operating time, the regional pipe valve is closed and the device switches back to the standby mode. The ambient temperature and the pipe water temperature are used to determine whether there is a risk of freezing. If there is a risk of freezing, the pipes inside and outside the target area are allowed to circulate liquid to increase the pipe water temperature, thereby avoiding the frequent start-up of the device for heating and making anti-freezing more convenient and less energy-consuming.

[0072] The temperature acquisition unit 11 is used to acquire the ambient temperature and the pipe water temperature when the temperature control device is in a standby state;

[0073] For details, please refer to Figure 6 , is a schematic diagram of the structure of a temperature acquisition unit provided in an embodiment of the present application. Figure 6 As shown, the temperature acquisition unit 11 may include:

[0074] An ambient temperature acquisition subunit 111 is used to acquire the ambient temperature outside the target area;

[0075] The pipe temperature acquisition subunit 112 is used to acquire the water inlet temperature and water outlet temperature between the heat pump unit and the pipe outside the target area, and acquire the heat source outlet temperature at the auxiliary heat source;

[0076] The minimum value determination subunit 113 is used to obtain the minimum temperature value among the water inlet temperature, the water outlet temperature and the heat source outlet temperature, and determine the minimum temperature value as the pipeline water temperature.

[0077] A first valve control unit 12, configured to switch to an anti-freezing state and open a regional pipeline valve when the ambient temperature is greater than a first preset ambient temperature and the pipeline water temperature is less than the first preset water temperature, wherein the regional pipeline valve is configured to control the flow of liquid between the pipeline in the target area and the pipeline outside the target area;

[0078] A third valve control unit 14 is used to switch to an anti-freezing state and open a regional pipeline valve if the ambient temperature is lower than a second preset ambient temperature and the pipeline water temperature is lower than the second preset water temperature;

[0079] Among them, the first preset ambient temperature is greater than or equal to the second preset ambient temperature, and the first preset water temperature is greater than the second preset water temperature.

[0080] The second valve control unit 13 is used to close the regional pipeline valve and switch back to the standby state if the pipeline water temperature is greater than the first standby water temperature after the first operating time.

[0081] The auxiliary heat source control unit 15 is used to start the auxiliary heat source for heating if the pipe water temperature is lower than the first standby water temperature after the first operation time;

[0082] If the pipeline water temperature during the second operating time is greater than the second standby water temperature, the regional pipeline valve and the auxiliary heat source are closed, and the system is switched back to the standby state.

[0083] Optionally, the auxiliary heat source control unit 15 is specifically used to obtain the shutdown time of the compressor;

[0084] If the pipeline water temperature is lower than the first standby water temperature after the first operating time, and the shutdown time is longer than a preset time threshold, the auxiliary heat source is started.

[0085] a first compressor control unit 16, configured to shut down the auxiliary heat source and start the compressor for heating if the pipe water temperature is lower than the second standby water temperature and the auxiliary heat source operation time is longer than the second operation time;

[0086] If the pipeline water temperature is greater than the third standby water temperature, the regional pipeline valve and the compressor are closed, and the system is switched back to the standby state.

[0087] The second compressor control unit 17 is used to close the regional pipeline valve and the compressor and switch back to the standby state if the compressor running time is greater than the third running time.

[0088] In this embodiment, when the temperature control device is in standby mode, the ambient temperature and the pipe water temperature are obtained. The pipe water temperature is the minimum temperature among the water inlet temperature, the water outlet temperature and the heat source outlet temperature, which further improves the accuracy of the pipe water temperature and avoids missing detection and causing pipe freezing. If the ambient temperature is greater than the first preset ambient temperature and the pipe water temperature is less than the first preset water temperature, it is switched to the anti-freezing state and the regional pipe valve is opened. If the heat pump anti-freezing device detects that the ambient temperature is less than the second preset ambient temperature and the pipe water temperature is less than the second preset water temperature, it is switched to the anti-freezing state and the regional pipe valve is opened. The second preset water temperature is lower than the first preset water temperature, which can prevent the wrong judgment of the existence of freezing risk, further avoid the frequent startup of the temperature control device, and achieve the purpose of reducing energy consumption. If the pipe water temperature is greater than the first standby water temperature after the first running time, the regional pipe valve is closed and switched back to the standby state. Whether there is a freezing risk is determined by the ambient temperature and the pipe water temperature. If there is a freezing risk, the pipes inside and outside the target area are circulated with liquid to increase the pipe water temperature, which avoids the frequent startup of the equipment for heating, making anti-freezing more convenient and lower energy consumption. If the pipeline water temperature is lower than the first standby water temperature after the first operating time, the auxiliary heat source is started for heating, and anti-freezing treatment is performed through the auxiliary heat source to avoid energy loss caused by starting the compressor. And the auxiliary heat source can be started only when the compressor shutdown time is longer than the preset time threshold, thereby avoiding the situation where the four-way valve cannot turn normally and the heating cannot be turned on normally, further improving the reliability of the heat pump anti-freezing. If the pipeline water temperature is higher than the second standby water temperature during the second operating time, the regional pipeline valve and the auxiliary heat source are closed, and the system is switched back to the standby state. If the pipeline water temperature is lower than the second standby water temperature, the auxiliary heat source is turned off, and the compressor is started for heating. If the pipeline water temperature is higher than the third standby water temperature, the regional pipeline valve and the compressor are closed and switched back to the standby state. The compressor is combined with the anti-freezing treatment to avoid the situation where the unit water system pipeline is broken due to insufficient anti-freezing capacity of the auxiliary heat source.

In addition, the heat pump antifreeze device provided in the above embodiment and the heat pump antifreeze method embodiment belong to the same concept, and the embodiment and implementation process thereof are detailed in the method embodiment, which will not be repeated here.

[0091] The present application also provides a computer storage medium, which can store multiple instructions, and the instructions are suitable for being loaded and executed by a processor as described above. Figure 1-Figure 3 The heat pump anti-freezing method of the embodiment shown in the figure can be specifically implemented by referring to Figure 1-Figure 3 The specific description of the illustrated embodiment will not be repeated here.

[0092] The present application also provides a computer program product, which stores at least one instruction, and the at least one instruction is loaded and executed by the processor as described above. Figure 1-Figure 3 The heat pump anti-freezing method of the embodiment shown in the figure can be specifically implemented by referring to Figure 1-Figure 3 The specific description of the illustrated embodiment will not be repeated here.

[0093] Please refer to Figure 7 , which shows a block diagram of the structure of an electronic device provided by an exemplary embodiment of the present application. The electronic device in the present application may include one or more of the following components: a processor 110, a memory 120, an input device 130, an output device 140, and a bus 150. The processor 110, the memory 120, the input device 130, and the output device 140 may be connected via the bus 150.

[0094] The processor 110 may include one or more processing cores. The processor 110 uses various interfaces and lines to connect various parts of the entire electronic device, and executes various functions and processes data of the terminal 100 by running or executing instructions, programs, code sets or instruction sets stored in the memory 120, and calling data stored in the memory 120. Optionally, the processor 110 can be implemented in at least one hardware form of digital signal processing (DSP), field-programmable gate array (FPGA), and programmable logic array (PLA). The processor 110 can integrate one or a combination of a central processing unit (CPU), a graphics processing unit (GPU), and a modem. Among them, the CPU mainly processes the operating system, user pages, and applications; the GPU is responsible for rendering and drawing display content; and the modem is used to process wireless communications. It can be understood that the above-mentioned modem may not be integrated into the processor 110, but may be implemented separately through a communication chip.

[0095] The memory 120 may include a random access memory (RAM) or a read-only memory (ROM). Optionally, the memory 120 includes a non-transitory computer-readable medium (Non-Transitory Computer-Readable Storage Medium). The memory 120 may be used to store instructions, programs, codes, code sets or instruction sets. The memory 120 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for implementing at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the above-mentioned various method embodiments, etc. The operating system may be an Android system, including a system deeply developed based on the Android system, an IOS system developed by Apple, including a system deeply developed based on the IOS system or other systems.

[0096] The memory 120 can be divided into an operating system space and a user space. The operating system runs in the operating system space, and native and third-party applications run in the user space. In order to ensure that different third-party applications can achieve good operating results, the operating system allocates corresponding system resources to different third-party applications. However, the requirements for system resources in different application scenarios in the same third-party application are also different. For example, in the local resource loading scenario, the third-party application has higher requirements for disk reading speed; in the animation rendering scenario, the third-party application has higher requirements for GPU performance. The operating system and third-party applications are independent of each other, and the operating system often cannot perceive the current application scenario of the third-party application in a timely manner, resulting in the operating system being unable to perform targeted system resource adaptation according to the specific application scenario of the third-party application.

[0097] In order for the operating system to distinguish the specific application scenarios of third-party applications, it is necessary to open up data communication between third-party applications and the operating system so that the operating system can obtain the current scenario information of third-party applications at any time, and then perform targeted system resource adaptation based on the current scenario.

[0098] The input device 130 is used to receive input commands or data, and includes but is not limited to a keyboard, a mouse, a camera, a microphone, or a touch device. The output device 140 is used to output commands or data, and includes but is not limited to a display device and a speaker. In one example, the input device 130 and the output device 140 can be combined, and the input device 130 and the output device 140 are touch screen displays.

[0099] The touch display screen can be designed as a full screen, a curved screen or a special-shaped screen. The touch display screen can also be designed as a combination of a full screen and a curved screen, or a combination of a special-shaped screen and a curved screen, which is not limited in the embodiments of the present application.
