The first ice-making water tank 109 is connected to the water source and arranged in the first chamber 101, and is used for pre-cooling water for ice making. In this embodiment, when the water temperature in the cold storage water tank 104 is difficult to provide cold 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 is arranged to discharge water into the cold storage water tank 104 through the second pipe 106, so as to adjust the water temperature in the cold storage water tank 104 while providing cold to the environment. In some embodiments, when the water level in the cold storage water tank 104 is insufficient, water can also be guided into the heat exchanger 103 through the third pipe 108, and the outlet of the heat exchanger 103 is arranged to discharge water into the cold storage water tank 104 through the second pipe 106, so as to adjust the water level in the cold storage water tank 104 while providing cold to the environment.

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 into the cold storage water tank 104 through the heat exchanger 103 and the second pipe 106, so as to supplement the water in the cold storage water tank 104.
[0057] In some embodiments, the cold storage water tank 104 is connected with a drain pipe 115, and a drain valve is arranged on the drain pipe 115; when the water temperature in the cold storage water tank 104 is insufficient to release cold to the environment, the drain valve can be started to drain the cold storage 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, 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 into the cold storage water tank 104 through the heat exchanger 103 and the second pipe 106, so as to supplement the cold water in the cold storage water tank 104.
[0058] In some embodiments, the machine body 01 further comprises a second chamber 111 for freezing food. The second chamber 111 further comprises a second ice-making water tank 113; the first ice-making water tank 109 and the second ice-making water tank 113 are connected through a communication valve. When ice making is needed, the communication valve is opened, and the pre-cooled water in the first ice-making water tank 109 is discharged into the second ice-making water tank 113 to make ice. In some embodiments, the first ice-making water tank 109 is connected with a water supply pipe 116, and a water supply valve is arranged on the water supply pipe 116; in the case where the ice making mode is not started, if the water level in the first ice-making water tank 109 is lower than a first preset value, the water supply valve is controlled to be opened, 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 started, the communication valve is opened, and when the water level in the first ice-making water tank 109 is 0, the communication valve is closed. In some embodiments, when the ice making mode is started, if the water level in the first ice-making water tank 109 is higher than a second preset value, the communication valve is controlled to be opened, and if not, water is injected into the first ice-making water tank 109 through the water supply pipe.
[0059] In the above embodiments, the cold storage water tank 104, the first ice-making water tank 109 and the heat exchanger 103 are combined as a water storage cooling system of the refrigeration device, which is used to provide cold to the environment, and realizes the basic function of the air conditioner.
[0060] As an optional implementation of the above embodiments, the refrigeration device further comprises a compressor 201 and a refrigeration evaporator 110 configured to provide cold to the first chamber 101; the compressor 201 is connected with the refrigeration evaporator 110. In this embodiment, the compressor 201 and the refrigeration evaporator 110 are combined as a refrigerant function cycle system of the refrigeration device, which is used to provide cold to the first chamber 101, and has the energy supply function of the refrigerator.
[0061] In one embodiment, the compressor 201 compresses the refrigerant and then delivers it to the refrigerated evaporator 110 after passing through the condenser 202 and a throttling device. The refrigerated evaporator 110 provides cooling to the first compartment 101, and the refrigerant after heat exchange is sent back into the compressor 201, thereby achieving refrigerant circulation. In some embodiments, when the cooling capacity in the cold water storage tank 104 is insufficient, the frequency of the compressor 201 can be increased to allow the refrigerated evaporator 110 to provide more cooling to the first compartment 101, thereby promoting rapid cooling of the water in the cold water storage tank 104.
[0062] In some embodiments, refer to Figure 1 As shown, the refrigeration equipment comprises two parts: an indoor unit and an outdoor unit 02; the unit body 01 is the indoor unit. The outdoor unit 02 is equipped with a compressor 201 and a condenser 202. The indoor unit has a first compartment 101, an air duct structure 102, and a refrigerated air duct. The indoor unit includes a heat exchanger 103, a chilled water tank 104, and a refrigerated evaporator 110. The refrigerated evaporator 110 is located inside the refrigerated air duct, with both ends of the refrigerated air duct connected to the first compartment 101. The fan 114 of the refrigerated air duct draws air from the first compartment 101 into the refrigerated air duct, so that the air exchanges heat with the refrigerated evaporator 110 and is then returned to the first compartment 101, thereby providing cooling to the first compartment 101.
[0063] In some embodiments, the indoor unit further includes a second compartment 111 and a refrigeration duct, and also includes a refrigeration evaporator 112. The refrigeration evaporator 112 is disposed within the refrigeration duct, with both ends of the refrigeration duct connected to the second compartment 111. A fan 114 in the refrigeration duct draws air from the second compartment 111 into the refrigeration duct, so that the air exchanges heat with the refrigeration evaporator 112 and is then returned to the second compartment 111, thereby providing cooling to the second compartment 111. In an embodiment, the refrigeration evaporator 112 and the refrigeration evaporator 110 are configured in parallel. After passing through the condenser 202, the refrigerant enters the refrigeration evaporator 112 and the refrigeration evaporator 110 respectively, and then the refrigerant after heat exchange flows to the inlet of the compressor 201, realizing refrigerant circulation. In this embodiment, the compressor 201, condenser 202, freezer evaporator 112, refrigerator evaporator 110, and throttling device are combined to form the refrigerant circulation system of the refrigeration equipment, which is used to provide cooling capacity to the first compartment 101 and the second compartment 111 to realize the function of a refrigerator.
[0064] In the above embodiment, a fan 114 is provided inside the air duct structure 102. The fan 114 is used to draw air from 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 device provided by the above embodiments can have air conditioning function and refrigerator function; in some embodiments, the air conditioning function mainly includes air supply refrigeration function (only the inner fan 114 is turned on) and cold storage refrigeration function (the inner 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 application also provides a control method for controlling the refrigerator-air conditioner integrated refrigeration device. The refrigerator-air conditioner integrated refrigeration device adopts part or all of the above embodiments. As shown in the figure, the refrigeration device includes a cold storage phase S100 and a refrigeration phase S200. Figure 2
[0067] As shown in the figure, the control method includes: Figure 3
[0068] S201, obtaining an ambient temperature;
[0069] S202, if the ambient temperature is greater than a first preset temperature, controlling the refrigeration device 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 an air conditioning function opening instruction, at this time, the refrigeration device enters the cold storage phase S200, obtains the ambient temperature, and when the ambient temperature is greater than the first preset temperature, the refrigeration device enters the first mode, at this time, 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 controlled 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.
[0071] In an embodiment, the first preset temperature is set by the system and can be corrected and modified by the user. In some embodiments, after the user sends an air conditioning function instruction 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 run at a preset parameter.
[0072] As an optional implementation of the above embodiments, before the control method controls the refrigeration device to enter the first mode if the ambient temperature is greater than the first preset temperature, as shown in the figure, the control method further includes: Figure 4
[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 less than the second preset temperature, controlling the refrigeration device to enter a third mode; in the third mode, the cold storage water tank 104 is in communication with 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 less than a third preset temperature, controlling the refrigeration device 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 cold energy the cold storage water tank 104 can provide; when releasing cold energy to the environment, it is necessary to ensure that the cold storage capacity of the cold storage water tank 104 is sufficient; therefore, before the environmental temperature needs to be adjusted, the device needs to enter the cold storage stage S100 to adjust the water temperature of the cold storage water tank 104 to below 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, at which time the temperature in the first chamber 101 is reduced, such as by increasing the frequency of the compressor 201 to reduce the temperature in the first chamber 101, adjusting the opening of the throttling device to reduce the temperature in 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 rapidly cooled by the refrigerant circulation system to reduce the temperature in the first chamber 101 until the water temperature is below the second preset temperature.
[0079] When the water temperature is less than the second preset temperature, the water temperature of the cold storage water tank 104 is relatively reduced, and because there is residual cold water in the heat exchanger 103, the refrigeration device enters the third mode at this time, the cold storage water tank 104 is in communication with the heat exchanger 103, and the water circulates in the cold storage water tank 104 and the heat exchanger 103. At this time, whether the refrigeration device enters the fourth mode is determined by the temperature difference between the return water temperature and the water temperature; when the temperature difference between the return water temperature and the water temperature is less 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, at which time the fourth mode can be entered, and the cold storage mode is in a disconnected state with the heat exchanger 103. At this time, wait for the instruction to start the air conditioning function.
[0080] In some embodiments, when the user initiates the air conditioning function, the pump 107, the compressor 201 and the fan 114 keep running at the initial set parameters, and the parameters are adjusted by obtaining the ambient temperature. As an alternative embodiment of the above embodiment, if the ambient temperature is greater than the first preset temperature, the control method further comprises: Figure 5 As shown in the above embodiment, the control method further comprises:
[0081] S203, if the ambient temperature is greater than the fourth preset temperature, the speed of the fan 114 in the air duct structure 102 is increased, wherein the fourth preset temperature is greater than the first preset temperature.
[0082] In an embodiment, after the user initiates the air conditioning function, the pump 107, the compressor 201 and the fan 114 keep running at the initial set parameters, and when the ambient temperature is greater than the first preset temperature and higher than the fourth preset temperature, the speed of the fan 114 is increased to increase the heat exchange intensity and quickly reduce the temperature.
[0083] In some embodiments, as shown in the above embodiment, if the ambient temperature is greater than the first preset temperature, the control method further comprises: Figure 6
[0084] S205, the water temperature of the cold storage water tank 104 and the return water temperature of the cold storage water tank 104 are obtained.
[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 water amount 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 storage system far exceeds the required cooling capacity of the environment, and at this time, the speed of the water pump 107 is reduced, and the water amount provided to the heat exchanger 103 is reduced to reduce the cooling capacity.
[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 a sixth preset temperature, the cold storage water tank 104 is controlled to increase the water amount provided to the heat exchanger 103 and / or reduce the temperature of the first chamber 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 indicates that the heat load of the environment is large, and the cooling capacity is insufficient, at this time, the heat exchanger 103 can be provided with a larger water amount and / or the temperature of the first chamber 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 has been running at the maximum speed, the frequency of the compressor 201 can be increased, and the temperature of the first chamber 101 can be reduced; 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, after the speed of the compressor 201 or the pump 107 is increased, in order to avoid the outlet air temperature of the air outlet being too cold, if the outlet air temperature is lower than the lower temperature that causes user discomfort, the outlet air temperature of the air outlet is obtained, and compared with a ninth preset temperature, if the outlet air temperature of the air outlet is less than the ninth preset temperature, it indicates that the outlet air temperature is low, at this time, the speed of the inner fan 114 can be reduced, so as to reduce the air amount in the air duct structure 102, so as to increase the outlet air temperature.
[0088] In the above-mentioned embodiments, the water temperature of the cold storage water tank 104 refers to the internal water temperature, and the return water temperature of the cold storage water tank 104 refers to the water temperature of the water entering the cold storage water tank 104 after passing through the heat exchanger 103 (which can be measured by arranging a temperature sensor on the second pipeline 106).
[0089] In some embodiments, when the user issues a start air conditioning function, the pump 107, the compressor 201 and the fan 114 remain at the initial set parameters for operation, at this time, the environmental temperature is obtained to adjust the parameters. As an optional implementation manner of the above-mentioned embodiment, if the environmental temperature is less than the first preset temperature, the refrigeration equipment is controlled to enter a fifth mode; in the fifth mode, the cold storage water tank 104 is cut off 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 started, if the environmental temperature is less than the first preset temperature, the environmental temperature meets the comfort requirement of the user, at this time, the refrigeration equipment enters the fifth mode, at this time, the pump 107 is closed, and in the case that the cold storage water tank 104 does not provide cold water to the heat exchanger 103, the air only exchanges heat with the residual cold water in the heat exchanger 103, so as to avoid blowing out the over-cooled air to cause user discomfort.
[0090] As an optional implementation of the above embodiment, as shown in Figure 7 After the control of the refrigeration device into 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 less than the seventh preset temperature, reducing the rotating speed of the fan 114 in the air duct structure 102.
[0093] In the embodiment, when the ambient temperature is less than the first preset temperature, the blown cold air can make the user feel cold, so the air outlet temperature judgment is added: by obtaining the air outlet temperature of the air outlet, the air outlet temperature is compared with the seventh preset temperature, if the air outlet temperature of the air outlet is less than the seventh preset temperature, it means that the air outlet temperature is low, at this time the rotating speed of the fan 114 can be reduced to reduce the air volume in the air duct structure 102, so as to increase the air outlet temperature; the residual cold quantity of the heat exchanger 103 is less and less, the air outlet temperature is increased, until the ambient temperature rises to the first preset temperature, and the first mode is re-entered to run.
[0094] In some embodiments, if the air outlet temperature is higher than the eighth preset temperature, the rotating speed of the fan 114 is reduced to the lowest wind stop to reduce the air outlet temperature.
[0095] As an optional implementation of the above embodiment, as shown in Figure 8 Before the control of the refrigeration device into 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 the preset water level, controlling to inject water into the cold storage water tank 104.
[0098] In the embodiment, when the cold quantity is released to the environment outside, 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 quantity is sufficient when it is needed to release the cold quantity. Therefore, in the embodiment, it is judged in advance whether the water level of the cold storage water tank 104 is lower than the preset water level, if yes, water is injected into 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 comprises a first ice-making water tank 109 and a third pipe 108; the first ice-making water tank 109 is arranged in the first chamber 101; the first ice-making water tank 109 is connected to the first pipe 105 through the third pipe 108; and 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 arranged in the first chamber 101, and is used for pre-cooling water for ice making. When the water level in the cold storage water tank 104 is insufficient, water can be guided into 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 as to increase the water level in the cold storage water tank 104 while providing cold energy to the environment.
[0100] In some embodiments, the cold storage stage S100 comprises steps S101-S106, and the cooling supply stage S200 comprises steps S201-S209. In some embodiments, the cooling supply stage is performed after the completion of the cold storage stage.
