[0054] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] The embodiments of the present application provide embodiments of a refrigeration equipment control method. It should be noted that although a logical sequence is shown in the flow chart, under certain data, the steps shown or described may be completed in an order different from that shown here.

[0056] Combine the following Figures 1 to 4 The present invention describes a refrigeration equipment control method, device, refrigeration equipment and electronic equipment.

[0057] Before introducing the refrigeration equipment control method of the embodiment of the present application, the application scenario of the refrigeration equipment control method is first explained. The refrigeration equipment control method of the present application can be applied to smart terminals such as smart phones, tablets and computers connected to the refrigeration equipment, and can also be applied to servers connected to the refrigeration equipment. It can also be applied to the control components of the refrigeration equipment. The present application is not specifically limited here, as long as it can carry and implement the refrigeration equipment control method of the present application.

[0058] It should be noted that if Figure 4 As shown, the inlet of the regulating valve of the refrigeration equipment of the present application is connected to the condenser, the first outlet of the regulating valve is connected to the inlet of the refrigeration evaporator, the outlet of the refrigeration evaporator is connected to the inlet of the freezing evaporator, and the second outlet of the regulating valve is connected to the inlet of the freezing evaporator.

[0059] The refrigeration evaporator is located in the refrigeration room and is mainly used to cool the refrigeration room. The freezing evaporator is located in the freezer room and is mainly used to cool the freezer room.

[0060] The following description will be given by applying the refrigeration equipment control method to a server side. However, it should be understood that the refrigeration equipment control method is not limited to being applied only to a server side.

[0061] According to the embodiment of the first aspect of the present application, Figure 1 As shown, the refrigeration equipment control method includes:

[0062] Step 101: determine whether the regulating valve has a leakage fault.

[0063] Specifically, during the use of the refrigeration equipment, the server side detects the state of the regulating valve and then determines whether the regulating valve has a leakage failure. When it is determined that the regulating valve has a leakage failure, the control method of the refrigeration equipment of the present application is applied to the refrigeration control of the refrigeration equipment. When the regulating valve has not a leakage failure, the refrigeration control of the refrigeration equipment is not changed.

[0064] Step 102: Control the inlet of the regulating valve to communicate with the first outlet of the regulating valve.

[0065] Specifically, after determining that the regulating valve has a leakage failure, the server side controls the inlet of the regulating valve and the first outlet of the regulating valve to be connected, that is, the condenser and the refrigeration evaporator are connected, so that the refrigeration equipment is in a state of regulating the temperature of the refrigeration room.

[0066] It can be understood that the regulating valve is a valve with regulating function such as a solenoid valve or an electric valve, so that the server side can control the regulating valve to switch between a state in which the inlet is connected to the first outlet and a state in which the inlet is connected to the second outlet.

[0067] It can be understood that when it is determined that a leakage failure has occurred in the regulating valve, the inlet and the first outlet of the regulating valve are directly connected, and the inlet and the second outlet are disconnected, so that the condenser and the refrigerated evaporator are connected, so that the condensing agent at this time directly enters the refrigerated evaporator, and at the same time, corresponding control is performed according to the real-time temperature of the refrigerated room to control the temperature in the refrigerated room within a certain range, which can effectively ensure that the temperature in the refrigerated room will not be too low.

[0068] It can be understood that since the inlet of the regulating valve is connected to the first outlet, the condensing agent directly enters the refrigerated evaporator, and the refrigerated evaporator and the frozen evaporator are connected. Therefore, when the refrigerated chamber is refrigerated, a small amount of condensing agent will also flow to the frozen evaporator, that is, the frozen chamber will also have a certain refrigeration effect at this time, thereby effectively preventing the temperature in the frozen chamber from rising too quickly.

[0069] Step 103, obtaining the real-time temperature in the refrigeration chamber.

[0070] It is understandable that after controlling the inlet of the regulating valve to be connected to the first outlet of the regulating valve, the server side will obtain the real-time temperature in the cold storage room, so as to control the refrigeration equipment accordingly according to the real-time temperature in the cold storage room.

[0071] For example, the real-time temperature in the cold storage room may be detected by a temperature sensor, and the server may obtain the real-time temperature in the cold storage room by acquiring the detection data of the temperature sensor.

[0072] Step 104, determining that the real-time temperature is less than a first preset temperature value, and controlling the refrigeration device to enter a cold storage protection mode;

[0073] Wherein, in the cold storage protection mode, the compressor of the refrigeration equipment stops working.

[0074] It can be understood that the server side compares the real-time temperature in the cold storage room with the first preset temperature value. When it is determined that the real-time temperature is less than the first preset temperature value, it means that the temperature in the cold storage room is already in a relatively low state. If it continues to decrease, the temperature in the cold storage room will be too low. The server side then controls the refrigeration equipment to enter the cold storage protection mode, causing the compressor of the refrigeration equipment to stop working to prevent the temperature in the cold storage room from continuing to decrease.

[0075] It is understandable that in the cold storage protection mode, not only the compressor of the refrigeration equipment but also the refrigeration fan of the refrigeration chamber may be turned off.

[0076] Exemplarily, the first preset temperature value is, for example, 0° C. to -10° C. Preferably, the first preset temperature value is -2° C.

[0077] In the refrigeration equipment control method of the embodiment of the present application, after the server determines that the regulating valve has a leakage fault, it first controls the inlet of the regulating valve to be connected to the first outlet, and the inlet and the second outlet are disconnected, so that the condenser is connected to the refrigeration evaporator, that is, the refrigeration room can be refrigerated. Then the server will obtain the real-time temperature in the refrigeration room, and compare the real-time temperature with the first preset temperature value. When it is determined that the real-time temperature is less than the first preset temperature value, it means that the temperature in the refrigeration room is already at the lower limit value at this time, then the server controls the refrigeration equipment to enter the refrigeration protection mode, so that the compressor stops working, and ensures that the temperature in the refrigeration room will not continue to drop. That is, the present application realizes that after determining that a refrigerant leakage fault has occurred, the temperature in the refrigeration room is detected. When the temperature in the refrigeration room is lower than the preset value, the refrigeration equipment is controlled to enter the refrigeration protection mode, thereby effectively avoiding the icing of the inlet of the refrigeration room and the excessively low temperature in the refrigeration room.

[0078] In one embodiment of the present application, after controlling the refrigeration device to enter the cold storage protection mode, the method includes:

[0079] Determining that the temperature in the refrigerating chamber is greater than the startup temperature of the refrigerating chamber;

[0080] The refrigeration device is controlled to exit the cold storage protection mode to cool the cold storage room.

[0081] In this embodiment, after the server controls the refrigeration device to enter the cold storage protection mode, it will continue to obtain the temperature in the cold storage room and compare the temperature in the cold storage room with the startup temperature of the cold storage room. When it is determined that the temperature in the cold storage room is greater than the startup temperature of the cold storage room, it means that the temperature in the cold storage room has risen and the cold storage room needs to be cooled down. Then the server controls the refrigeration device to exit the cold storage protection mode and cool down the cold storage room to avoid the temperature in the cold storage room being too high.

[0082] It can be understood that the startup temperature of the refrigerator compartment refers to the starting refrigeration temperature of the refrigerator compartment, that is, the temperature in the refrigerator compartment reaches the temperature at which the refrigerator compartment needs to be cooled down. At this time, the temperature in the refrigerator compartment has risen and the refrigerator compartment needs to be cooled down.

[0083] It is understandable that after exiting the refrigeration protection mode, the compressor starts to work. At this time, the refrigeration fan of the refrigeration chamber can also start to work, which can speed up the cooling speed in the refrigeration chamber.

[0084] In one embodiment of the present application, after controlling the refrigeration device to enter the cold storage protection mode, the method includes:

[0085] Determining that the temperature in the freezer compartment is higher than a startup temperature of the freezer compartment;

[0086] The refrigeration device is controlled to exit the cold storage protection mode to cool the freezer compartment.

[0087] It is understandable that after the server controls the refrigeration equipment to enter the cold protection mode, it will obtain the temperature inside the freezer and compare the temperature inside the freezer with the startup temperature of the freezer. When it is determined that the temperature inside the freezer is greater than the startup temperature of the freezer, the server will control the refrigeration equipment to exit the cold protection mode and cool down the freezer to avoid the temperature inside the freezer being too high.

[0088] It can be understood that the start-up temperature of the freezer refers to the starting refrigeration temperature of the freezer, that is, the temperature in the freezer reaches the temperature at which the freezer needs to be cooled down. At this time, the temperature of the freezer has risen and the freezer needs to be cooled down.

[0089] It is understandable that after exiting the refrigeration protection mode, the compressor starts working, and some condensing agent will enter the freezing evaporator, which can play a certain role in cooling the freezing chamber. The freezing chamber can also be cooled directly, that is, the condenser is directly connected to the freezing evaporator to achieve rapid cooling of the freezing chamber. It should be noted that the freezing chamber can also be cooled by any other suitable method.

[0090] In an embodiment of the present application, controlling the refrigeration device to exit the cold storage protection mode to cool the freezing chamber includes:

[0091] Determining that the temperature in the freezing chamber is less than a second preset temperature value;

[0092] Determining that the temperature in the refrigerating chamber is greater than or equal to the first preset temperature value;

[0093] Controlling the cooling operation of the refrigerating chamber.

[0094] It is understandable that after the server determines that the temperature in the freezer is higher than the startup temperature of the freezer, it means that the freezer needs to be cooled down, and the server will control the refrigeration equipment to exit the cold storage protection mode. The server will also compare the temperature in the freezer with the second preset temperature value. When it is determined that the temperature in the freezer is less than the second preset temperature value, it means that the temperature in the freezer has risen, but has not reached the upper limit. At the same time, the server will also compare the temperature in the refrigerator with the first preset temperature value. When it is determined that the temperature in the refrigerator is greater than or equal to the first preset temperature value, it means that the temperature in the refrigerator has not reached the lower limit and can continue to cool down. Then the server controls the refrigerator to cool down. Since the refrigeration evaporator and the freezing evaporator are connected, when the refrigerator is cooled down, the temperature in the freezer will also drop, which can have a cooling effect on the freezer.

[0095] It is understandable that when the temperature in the freezer is less than the second preset temperature value, that is, when it has not reached the upper limit value, it means that the freezer does not need to be cooled quickly at this time, and slow cooling is also possible. At the same time, when the temperature in the refrigerator has not reached the lower limit value, it means that the refrigerator can still be cooled at this time, and the refrigerator can be cooled to achieve the effect of indirect cooling of the freezer. That is, when the temperature in the freezer is not too high and the temperature in the refrigerator is not too low, the refrigerator can be cooled to achieve indirect cooling of the freezer.

[0096] In an embodiment of the present application, controlling the refrigeration device to exit the cold storage protection mode to cool the freezing chamber includes:

[0097] Determining that the temperature in the freezing chamber is less than a second preset temperature value;

[0098] Determining that the temperature in the refrigerating chamber is greater than or equal to the first preset temperature value;

[0099] The regulating valve inlet is controlled to be connected to the second outlet, the freezing fan of the freezing chamber is controlled to work, and the refrigerating fan of the refrigerating chamber is controlled to stop working.

[0100] It is understandable that when the server determines that the temperature in the freezer is less than the second preset temperature value, and the temperature in the refrigerator is greater than or equal to the first preset temperature value, it means that the temperature in the freezer has risen, but has not reached the upper limit, and the temperature in the refrigerator has not reached the lower limit, and can continue to cool down. The server controls the inlet of the regulating valve to be connected to the second outlet, so that the condenser is connected to the freezing evaporator, and at the same time controls the freezing fan in the freezer to start working, so as to achieve rapid cooling of the freezer. At the same time, the server will control the refrigeration fan in the refrigerator to stop working, thereby reducing the temperature change rate in the refrigerator, that is, even if the condensing agent leaks to the refrigeration evaporator, the temperature in the refrigerator has not reached the lower limit of the first preset temperature value, so it will not cause the temperature in the refrigerator to be too low.

[0101] In an embodiment of the present application, controlling the refrigeration device to exit the cold storage protection mode to cool the freezing chamber includes:

[0102] Determining that the temperature in the freezing chamber is greater than or equal to a second preset temperature value;

[0103] Controlling the refrigeration equipment to enter a freezing protection mode;

[0104] In the freezing protection mode, the refrigeration fan of the refrigeration chamber is in a non-operating state, and the inlet of the regulating valve is communicated with the second outlet of the regulating valve.

[0105] It is understandable that after the server determines that the temperature in the freezer is higher than the startup temperature of the freezer, it means that the freezer needs to be cooled down, and the server will control the refrigeration equipment to exit the cold storage protection mode. The server will also compare the temperature in the freezer with the second preset temperature value. When it is determined that the temperature in the freezer is greater than or equal to the second preset temperature value, it means that the temperature in the freezer has reached the upper limit and the freezer needs to be cooled down quickly. The server will control the refrigeration equipment to enter the freezing protection mode, connect the inlet and the second outlet of the regulating valve, so that the condenser is directly connected to the freezing evaporator, so that the refrigerant can directly enter the freezing evaporator, and directly cool the freezer, so that the temperature in the freezer drops quickly, and the temperature in the freezer is prevented from being too high for a long time.

[0106] It is understandable that in the freezing protection mode, the refrigeration fan of the refrigeration chamber is in a non-operating state, which can reduce the temperature change rate in the refrigeration chamber and keep the temperature in the refrigeration chamber stable.

[0107] It is understandable that in the freezing protection mode, the freezing fan of the freezing chamber can also be controlled to operate to speed up the temperature drop rate in the freezing chamber.

[0108] In the embodiment of the present application, the second preset temperature value is, for example, in the range of -5°C to -40°C, preferably -12°C.

[0109] In an embodiment of the present application, after controlling the refrigeration device to enter the freezing protection mode, the method includes:

[0110] Determining that the temperature of the freezing chamber is less than or equal to the target temperature, and controlling the refrigeration device to exit the freezing protection mode;

[0111] The target temperature includes one of a shutdown temperature of the freezing chamber and the second preset temperature value.

[0112] It is understandable that after the server controls the refrigeration equipment to enter the freezing protection mode, it will continue to obtain the temperature in the freezer and compare the temperature in the freezer with the target temperature. When it is determined that the temperature in the freezer is less than or equal to the target temperature, it means that the temperature in the freezer has dropped. The refrigeration equipment is then controlled to exit the freezing protection mode to avoid the refrigeration equipment being in the freezing protection mode for a long time, which may cause the temperature of the refrigerator room to be too low.

[0113] It can be understood that the shutdown temperature of the freezer compartment refers to the temperature at which the freezer compartment stops refrigerating, that is, the temperature in the freezer compartment has dropped to a specified temperature and there is no need to refrigerate the freezer compartment any more.

[0114] In one embodiment of the present application, after obtaining the real-time temperature in the refrigerating chamber, the method includes:

[0115] Determine that the real-time temperature in the refrigerating chamber is greater than or equal to the startup temperature of the refrigerating chamber, and control the refrigerating fan of the refrigerating chamber to be in a working state,

[0116] Wherein, the startup temperature of the refrigerating chamber is greater than the first preset temperature value.

[0117] It is understandable that after determining that the regulating valve has a leakage fault, the server side will control the inlet of the regulating valve to be connected to the first outlet, and then the server side will obtain the real-time temperature in the cold storage room. After the server side obtains the real-time temperature in the cold storage room, the server side will compare the real-time temperature in the cold storage room with the startup temperature of the cold storage room. When it is determined that the real-time temperature in the cold storage room is greater than or equal to the startup temperature of the cold storage room, it means that the temperature in the cold storage room is high at this time and the cold storage room needs to be cooled down. Then, the cold storage fan of the cold storage room is controlled to be in working state to quickly cool down the cold storage room.

[0118] It can be understood that the startup temperature of the cold storage room is greater than the first preset temperature value, that is, after the server obtains the real-time temperature in the cold storage room, if the real-time temperature is greater than or equal to the startup temperature of the cold storage room, the refrigeration fan will be controlled to be in a working state first, and then when the real-time temperature in the cold storage room drops to less than the first preset temperature value, the refrigeration equipment will be controlled to enter the cold protection mode; if the real-time temperature is less than the first preset temperature value, the refrigeration equipment will be directly controlled to enter the cold protection mode.

[0119] In an embodiment of the present application, after controlling the refrigeration fan of the refrigeration chamber to be in a working state, the method includes:

[0120] Determine that the real-time temperature in the refrigerating chamber is lower than the shutdown temperature of the refrigerating chamber, and control the refrigerating fan to stop working.

[0121] It is understandable that after the server controls the refrigeration fan of the cold storage room to be in working state, the server will continue to obtain the real-time temperature of the cold storage room, and compare the real-time temperature of the cold storage room with the shutdown temperature of the cold storage room. When it is determined that the real-time temperature of the cold storage room is lower than the shutdown temperature of the cold storage room, it means that the temperature in the cold storage room has dropped. Then the refrigeration fan is controlled to stop working to avoid the temperature in the cold storage room from dropping too quickly.

[0122] It can be understood that the shutdown temperature of the refrigerating chamber refers to the temperature at which the refrigerating chamber stops cooling, that is, the temperature in the refrigerating chamber has dropped to a specified temperature and there is no need to refrigerate the refrigerating chamber any more.

[0123] In one embodiment of the present application, determining that a leakage fault occurs in the regulating valve includes:

[0124] Determining that the inlet of the regulating valve is in communication with the second outlet of the regulating valve;

[0125] Determining that the temperature of the defrost sensor of the refrigerating chamber is lower than a third preset value;

[0126] It is determined that a leakage failure occurs in the regulating valve.

[0127] It is understandable that when the server determines whether a regulating valve has a leakage fault, it will first determine whether the inlet of the regulating valve is connected to the second outlet of the regulating valve, that is, whether the condenser is directly connected to the freezing evaporator. If so, the temperature of the defrost sensor in the cold storage room is obtained, and the temperature of the defrost sensor is compared with the third preset value. When it is determined that the temperature of the defrost sensor is lower than the third preset value, it means that the temperature in the cold storage room has dropped abnormally at this time, and it is determined that a leakage fault has occurred in the regulating valve.

[0128] It can be understood that the third preset value is, for example, in the range of -5°C to -30°C, preferably -12°C.

[0129] According to the embodiment of the second aspect of the present application, the refrigeration equipment control device and the refrigeration equipment control method correspond to each other. Figure 2 As shown, the refrigeration equipment control device includes:

[0130] A determination module 201 is used to determine whether the regulating valve has a leakage fault;

[0131] A first control module 202, used to control the inlet of the regulating valve to communicate with the first outlet of the regulating valve;

[0132] The acquisition module 203 is used to obtain the real-time temperature in the refrigeration room;

[0133] The second control module 204 is used to control the refrigeration device to enter a cold storage protection mode when the real-time temperature is less than a first preset temperature value;

[0134] Wherein, in the cold storage protection mode, the compressor of the refrigeration equipment stops working.

[0135] In one embodiment of the present application, the refrigeration equipment control device is further used for:

[0136] Determining that the temperature in the refrigerating chamber is greater than the startup temperature of the refrigerating chamber;

[0137] The refrigeration device is controlled to exit the cold storage protection mode to cool the cold storage room.

[0138] In one embodiment of the present application, the refrigeration equipment control device is further used for:

[0139] Determining that the temperature in the freezer compartment is higher than a startup temperature of the freezer compartment;

[0140] The refrigeration device is controlled to exit the cold storage protection mode to cool the freezer compartment.

[0141] In one embodiment of the present application, the refrigeration equipment control device is further used for:

[0142] Determining that the temperature in the freezing chamber is less than a second preset temperature value;

[0143] Determining that the temperature in the refrigerating chamber is greater than or equal to the first preset temperature value;
