[0051] Reference Figure 1 As shown, as an optional implementation of the above embodiment, the refrigeration equipment also includes a first pipe 105, a second pipe 106 and a pump 107; the cold storage water tank 104 is connected to the inlet of the heat exchanger 103 through the first pipe 105, and the cold storage water tank 104 is connected to the outlet of the heat exchanger 103 through the second pipe 106; the pump 107 is arranged on the first pipe 105 or the second pipe 106.

[0052] In this embodiment, when it is necessary to provide cooling to the external environment or the cooling capacity of the heat exchanger 103 is insufficient to provide cooling to the environment, the water in the cold storage water tank 104 is pumped into the heat exchanger 103 through the first pipe 105 by the pump 107, and then transported back to the cold storage water tank 104 through the second pipe 106, so as to release cooling to the environment by circulating the cold water in the cold storage water tank 104.

The first ice-making water tank 109 is connected to a water source and placed in the first compartment 101 for precooling water for ice making. In this embodiment, when the water temperature in the cold storage water tank 104 is difficult to provide cold energy to the environment, cold water can be provided to the heat exchanger 103 through the third pipe 108, and the outlet of the heat exchanger 103 discharges water into the cold storage water tank 104 through the second pipe 106, so that the water temperature of the cold storage water tank 104 can be adjusted while providing cold energy to the environment. In some embodiments, when the water level in the cold water tank 104 is insufficient, water can be directed to the heat exchanger 103 through the third pipe 108, and the outlet of the heat exchanger 103 discharges the water to the cold water tank 104 through the second pipe 106, thereby adjusting the water level of the cold water tank 104 while providing cooling to the environment.

[0056] Reference Figure 1 As shown, the first pipe 105 includes a first pipe section and a second pipe section connected to each other; the first pipe section is connected to the cold storage water tank 104, and a first electric valve 117 is provided on the first pipe section; the third pipe 108 is connected to the second pipe section; the third pipe 108 and the first pipe section are connected in parallel and then connected to the second pipe section; the third pipe 108 is provided with a second electric valve 118. In some embodiments, when the water in the cold storage water tank 104 is insufficient, the first electric valve 117 can be closed, the second electric valve 118 can be opened, and the pump 107 can be started, so that the water in the first ice-making water tank 109 can be pumped into the second pipe section through the third pipe 108, and then transported to the cold storage water tank 104 through the heat exchanger 103 and the second pipe 106, so as to replenish the cold storage water tank 104 with water.

[0057] In some embodiments, the cold water tank 104 is connected to a drain pipe 115, and a drain valve is provided on the drain pipe 115; when the water temperature in the cold water tank 104 is not enough to release cold air to the environment, the drain valve can be activated to discharge the cold water in the cold water tank 104; then the first electric valve 117 can be closed, the second electric valve 118 can be opened, and the pump 107 can be started, and the water in the first ice-making water tank 109 can be pumped into the second pipe section through the third pipe 108, and then transported to the cold water tank 104 through the heat exchanger 103 and the second pipe 106 to replenish cold water to the cold water tank 104.

[0058] In some embodiments, the machine body 01 is further provided with a second compartment 111, and the second compartment 111 is used for freezing food. A second ice-making water tank 113 is further provided in the second compartment 111; the first ice-making water tank 109 and the second ice-making water tank 113 are connected by a connecting valve. When ice-making is required, the connecting valve is opened, and the pre-cooled water in the first ice-making water tank 109 is discharged to the second ice-making water tank 113 for ice-making. In some embodiments, the first ice-making water tank 109 is connected with a water supply pipe 116, and a water supply valve is provided on the water supply pipe 116; when the ice-making mode is not turned on, if the water level of the first ice-making water tank 109 is lower than the first preset value, the water supply valve is controlled to open, and water is injected into the first ice-making water tank 109 through the water supply pipe. In some embodiments, when the ice-making mode is turned on, the connecting valve is opened, and when the water level of the first ice-making water tank 109 is 0, the connecting valve is closed. In some embodiments, when the ice-making mode is turned on, if the water level of the first ice-making water tank 109 is higher than the second preset value, the control connecting valve is opened, if not, water is injected into the first ice-making water tank 109 through the water supply pipe.

[0059] In the above embodiment, the cold storage water tank 104, the first ice-making water tank 109 and the heat exchanger 103 are combined into a water cold storage and cooling system of the refrigeration equipment, which is used to provide cold air to the environment and realize the basic function of air conditioning.

[0060] As an optional implementation of the above embodiment, the refrigeration equipment further includes: a compressor 201; and a refrigeration evaporator 110, the refrigeration evaporator 110 is configured to provide coldness to the first compartment 101; the compressor 201 is connected to the refrigeration evaporator 110. In this embodiment, the compressor 201 and the refrigeration evaporator 110 are combined into a refrigerant function circulation system of the refrigeration equipment, which is used to provide coldness to the first compartment 101 and has the energy supply function of the refrigerator.

[0061] In an embodiment, after the compressor 201 compresses the refrigerant, it is transported to the refrigeration evaporator 110 after passing through the condenser 202 and the throttling device. The refrigeration evaporator 110 provides cooling to the first chamber 101, and the refrigerant after heat exchange is sent to the compressor 201, thereby realizing the circulation of the refrigerant. In some embodiments, when the cooling capacity in the cold storage water tank 104 is insufficient, the frequency of the compressor 201 can be controlled to increase so that the refrigeration evaporator 110 provides more cooling capacity to the first chamber 101, thereby promoting the rapid cooling of the water in the cold storage water tank 104.

[0062] In some embodiments, reference Figure 1 As shown, the refrigeration equipment includes two parts: an indoor unit and an outdoor unit 02; wherein the machine body 01 is the indoor unit. The outdoor unit 02 is provided with a compressor 201 and a condenser 202. The indoor unit is provided with a first chamber 101, an air duct structure 102 and a refrigeration air duct, and the indoor unit includes a heat exchanger 103, a cold storage water tank 104 and a refrigeration evaporator 110. The refrigeration evaporator 110 is arranged in the refrigeration air duct, and the two ends of the refrigeration air duct are respectively connected to the first chamber 101. The fan 114 of the refrigeration air duct sucks the air in the first chamber 101 into the refrigeration air duct, so that the air is returned to the first chamber 101 after heat exchange with the refrigeration evaporator 110, so as to provide cooling to the first chamber 101.

[0063] In some embodiments, the indoor unit is further provided with a second compartment 111 and a freezing air duct, and the indoor unit further includes a freezing evaporator 112. The freezing evaporator 112 is provided in the freezing air duct, and both ends of the freezing air duct are respectively connected to the second compartment 111. The fan 114 of the freezing air duct draws the air in the second compartment 111 into the freezing air duct, so that the air is returned to the second compartment 111 after heat exchange with the freezing evaporator 112, thereby providing cooling to the second compartment 111. In an embodiment, the freezing evaporator 112 and the refrigeration evaporator 110 are arranged in parallel, and the refrigerant enters the freezing evaporator 112 and the refrigeration evaporator 110 respectively after passing through the condenser 202, and then the refrigerant after heat exchange converges to the inlet of the compressor 201, thereby realizing the refrigerant circulation. In the embodiment, the compressor 201, the condenser 202, the freezing evaporator 112, the refrigerating evaporator 110, and the throttling device are combined into a refrigerant circulation system of the refrigeration equipment, which is used to provide cold air to the first chamber 101 and the second chamber 111 to realize the function of a refrigerator.

[0064] In the technical solution of the above embodiment, a fan 114 is provided in the air duct structure 102, and the fan 114 is used to draw air in the environment into the air duct structure 102 to exchange heat with the heat exchanger 103, reduce the air temperature, and then discharge it to the outside.

[0065] The refrigeration equipment provided in the above embodiments may have air conditioning function and refrigerator function; in some embodiments, the air conditioning function mainly includes air supply refrigeration function (only the internal fan 114 is turned on) and cold storage refrigeration function (the internal fan 114 is turned on and the pump 107 is turned on); in some embodiments, the refrigerator function includes ice making function, refrigeration function and freezing function.

[0066] The present application also proposes a control method for controlling a refrigerator-air conditioner integrated refrigeration device. The refrigerator-air conditioner integrated refrigeration device adopts part or all of the above embodiments. Figure 2 As shown, the refrigeration device includes a cold storage stage S100 and a refrigeration stage S200.

[0067] like Figure 3 As shown, the control method includes:

[0068] S201, obtaining the ambient temperature;

[0069] S202, if the ambient temperature is greater than a first preset temperature, the refrigeration device is controlled to enter a first mode; in the first mode, the cold storage water tank 104 provides cold water to the heat exchanger 103, and the fan 114 in the air duct structure 102 is started.

[0070] In an embodiment, when the ambient temperature needs to be adjusted, the user issues a command to turn on the air conditioning function. At this time, the refrigeration equipment enters the cold storage stage S200, obtains the ambient temperature, and when the ambient temperature is greater than the first preset temperature, the refrigeration equipment enters the first mode. At this time, the cold storage water tank 104 provides cold water to the heat exchanger 103, and controls the fan 114 in the air duct structure 102 to start; the cold storage water tank 104 directly provides cold water to the heat exchanger 103, and the cold water enters the heat exchanger 103 to exchange heat with the flowing air and release cold energy to the environment, so that the ambient temperature can be quickly cooled down.

[0071] In an embodiment, the first preset temperature is set by the system, and the user can modify and revise it. In some embodiments, after the user sends an instruction of the air conditioning function to the air conditioner, the refrigeration device enters a default mode, such as adjusting the fan 114, the pump 107 and the compressor 201 to operate under preset parameters.

[0072] As an optional implementation of the above embodiment, if the ambient temperature is greater than the first preset temperature, before controlling the refrigeration device to enter the first mode, Figure 4 As shown, the control method also includes:

[0073] S103, obtaining the water temperature of the cold storage water tank 104;

[0074] S104, if the water temperature is greater than a second preset temperature, controlling the refrigeration device to enter a second mode; in the second mode, the temperature of the first chamber 101 is reduced;

[0075] S105, if the water temperature is lower than the second preset temperature, the refrigeration device is controlled to enter the third mode; in the third mode, the cold storage water tank 104 is connected to the heat exchanger 103, and the return water temperature of the cold storage water tank 104 is obtained;

[0076] S106, when the temperature difference between the return water temperature and the water temperature is lower than a third preset temperature, the refrigeration device is controlled to enter a fourth mode; in the fourth mode, the cold storage water tank 104 is disconnected from the heat exchanger 103.

[0077] In this embodiment, the water temperature of the cold storage water tank 104 determines how much cooling capacity the cold storage water tank 104 can provide; when releasing cooling capacity to the environment, it is necessary to ensure that the cooling capacity of the cold storage water tank 104 is sufficient; therefore, before the ambient temperature needs to be adjusted, the device needs to enter the cooling stage S100 to adjust the water temperature of the cold storage water tank 104 to be lower than a certain set value.

[0078] Therefore, in the embodiment, when the water temperature is greater than the second preset temperature, the refrigeration device enters the second mode, and the temperature in the first chamber 101 is reduced. For example, the temperature of the first chamber 101 can be reduced by increasing the frequency of the compressor 201, and the opening of the throttling device can be adjusted to reduce the temperature of the first chamber 101. That is, in the embodiment, when the water temperature of the cold storage water tank 104 is high, the water in the cold storage water tank 104 is quickly cooled by reducing the temperature of the first chamber 101 through the refrigerant circulation system until the water temperature is lower than the second preset temperature.

[0079] When the water temperature is lower than the second preset temperature, the water temperature of the cold storage water tank 104 is relatively lowered, and since there is residual cold water in the heat exchanger 103, the refrigeration device enters the third mode, the cold storage water tank 104 is connected to the heat exchanger 103, and water circulates in the cold storage water tank 104 and the heat exchanger 103. At this time, the temperature difference between the return water temperature and the water temperature is used to determine whether the refrigeration device enters the fourth mode; when the temperature difference between the return water temperature and the water temperature is lower than the third preset temperature, it means that the water temperature in the water tank is close to the water temperature of the heat exchanger 103, and the fourth mode can be entered at this time, and the cold storage mode is disconnected from the heat exchanger 103. At this time, wait for the instruction to turn on the air conditioning function.

[0080] In some embodiments, when the user issues a signal to start the air conditioning function, the pump 107, the compressor 201, and the fan 114 maintain the initially set parameters for operation, and the parameters are adjusted by obtaining the ambient temperature. As an optional implementation of the above embodiment, if the ambient temperature is greater than the first preset temperature, the refrigeration device is controlled to enter the first mode, such as Figure 5 As shown, the control method also includes:

[0081] S203, if the ambient temperature is greater than a fourth preset temperature, controlling the speed of the fan 114 in the air duct structure 102 to increase, wherein the fourth preset temperature is greater than the first preset temperature.

[0082] In an embodiment, after the user starts the air conditioning function, the pump 107, compressor 201 and fan 114 are defaulted to operate at the initial set parameters. When the ambient temperature is greater than the first preset temperature, and even higher than the fourth preset temperature, the speed of the fan 114 is controlled to increase to increase the heat exchange intensity and quickly cool down.

[0083] In some embodiments, Figure 6 As shown, if the ambient temperature is greater than the first preset temperature, after controlling the refrigeration device to enter the first mode, the control method further includes:

[0084] S205, obtaining the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104;

[0085] S206, if the temperature difference between the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104 is less than the fifth preset temperature, the cold storage water tank 104 is controlled to reduce the amount of cold water provided to the heat exchanger 103; in this case, if the temperature difference between the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104 is less than the fifth preset temperature, it indicates that the cooling capacity of the water cold storage system far exceeds the required cooling capacity of the environment. At this time, the speed of the water pump 107 is reduced to reduce the amount of cold water provided to the heat exchanger 103 and thereby reduce the cooling supply.

[0086] S207, if the temperature difference between the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104 is greater than the sixth preset temperature, the cold storage water tank 104 is controlled to increase the amount of cold water provided to the heat exchanger 103 and / or reduce the temperature of the first compartment 101. In this case, if the temperature difference between the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104 is greater than the sixth preset temperature, it means that the heat load of the environment is large and the cooling capacity is insufficient. At this time, a larger amount of water can be provided to the heat exchanger 103 and / or the temperature of the first compartment 101 can be reduced to ensure that the cold storage water tank 104 can provide more cooling capacity. In some embodiments, if the pump 107 is already running at the maximum speed, the frequency of the compressor 201 can be increased to reduce the temperature of the first compartment 101; in some embodiments, if the pump 107 is not running at the maximum speed, the speed of the pump 107 can be increased to the maximum. In some embodiments, the frequency of the compressor 201 can be increased while the speed of the pump 107 is increased.

[0087] In an embodiment, when the speed of the compressor 201 or the pump 107 is increased, in order to avoid the outlet air temperature from being too cold, if the outlet air temperature is lower than a lower value and causes discomfort to the user, the outlet air temperature of the air outlet is obtained and compared with the ninth preset temperature. If the outlet air temperature of the air outlet is lower than the ninth preset temperature, it means that the outlet air temperature is relatively low. At this time, the rotation speed of the internal fan 114 can be reduced to reduce the air volume in the air duct structure 102, thereby increasing the outlet air temperature.

[0088] In the above embodiment, the water temperature of the cold water tank 104 refers to the water temperature inside it, and the return water temperature of the cold water tank 104 refers to the water temperature of the water before entering the cold water tank 104 after passing through the heat exchanger 103 (which can be measured by setting a temperature sensor on the second pipe 106).

[0089] In some embodiments, when the user issues a command to start the air conditioning function, the pump 107, the compressor 201, and the fan 114 maintain the initially set parameters for operation, and the parameters are adjusted by obtaining the ambient temperature. As an optional implementation of the above embodiment, if the ambient temperature is less than the first preset temperature, the refrigeration device is controlled to enter the fifth mode; in the fifth mode, the cold storage water tank 104 is disconnected from the heat exchanger 103, and the fan 114 in the air duct structure 102 is started. In this embodiment, after the air conditioning function is turned on, if the ambient temperature is less than the first preset temperature, the ambient temperature meets the user's comfort requirements, and the refrigeration device enters the fifth mode. At this time, the pump 107 is turned off. When the cold storage water tank 104 does not provide cold water to the heat exchanger 103, the air only exchanges heat with the cold water remaining in the heat exchanger 103, avoiding blowing out too cold wind to cause discomfort to the user.

[0090] As an optional implementation of the above embodiment, Figure 7 As shown, if the ambient temperature is less than the first preset temperature, after controlling the refrigeration device to enter the fifth mode, the method further includes:

[0091] S208, obtaining the air outlet temperature of the air outlet;

[0092] S209: If the air outlet temperature of the air outlet is lower than the seventh preset temperature, the rotation speed of the fan 114 in the air duct structure 102 is reduced.

[0093] In an embodiment, when the ambient temperature is lower than the first preset temperature, the cold air blown out may make the user feel cold, so an outlet air temperature judgment is added: by obtaining the outlet air temperature of the air outlet and comparing it with the seventh preset temperature, if the outlet air temperature of the air outlet is lower than the seventh preset temperature, it means that the outlet air temperature is relatively low. At this time, the rotation speed of the internal fan 114 can be reduced to reduce the air volume in the air duct structure 102, thereby increasing the outlet air temperature; subsequently, the remaining cold amount in the heat exchanger 103 becomes less and less, and the outlet air temperature increases, until the ambient temperature rises to the first preset temperature, and then the first mode of operation is re-entered.

[0094] In some embodiments, if the outlet air temperature is higher than the eighth preset temperature, the speed of the internal fan 114 is reduced to the lowest wind speed to reduce the outlet air temperature.

[0095] As an optional implementation of the above embodiment, Figure 8 As shown, if the ambient temperature is greater than the first preset temperature, before controlling the refrigeration device to enter the first mode, the control method further includes:

[0096] S101, obtaining the water level of the cold storage water tank 104;

[0097] S102, if the water level is lower than a preset water level, control the injection of water into the cold storage water tank 104.

[0098] In the embodiment, when releasing cold energy to the outside of the environment, it is necessary to ensure that the water level of the cold storage water tank 104 is above the preset water level so that the cold energy is sufficient when the cold energy needs to be released. To this end, in the embodiment, it is pre-determined whether the water level of the cold storage water tank 104 is lower than the preset water level, and if so, water is added to the cold storage water tank 104.

[0099] In some embodiments, the cold storage water tank 104 can be connected to a water source. In some embodiments, the refrigeration device further includes a first ice-making water tank 109 and a third pipe 108; the first ice-making water tank 109 is disposed in the first compartment 101; the first ice-making water tank 109 is connected to the first pipe 105 through the third pipe 108; the first ice-making water tank 109 is connected to a water source. The first ice-making water tank 109 is connected to a water source and is placed in the first compartment 101 for precooling ice-making water. When the water level in the cold storage water tank 104 is insufficient, water can be guided to the heat exchanger 103 through the third pipe 108, and the outlet of the heat exchanger 103 discharges water to the cold storage water tank 104 through the second pipe 106, thereby increasing the water level in the cold storage water tank 104 while providing cooling to the environment.

[0100] In some embodiments, the cold storage phase S100 includes steps S101 to S106, and the cold supply phase S200 includes steps S201 to S209. In some embodiments, the cold supply phase is performed after the cold storage phase is completed.

All equivalent structural changes made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present application.
