The refrigerating compartment 103, the freezing compartment 104, and the air-conditioning/cooling compartment 102 may be provided in this order from the bottom up.

The plate heat exchanger 107 may be a liquid-liquid heat exchanger such as a tube heat exchanger, or any heat exchanger that can exchange heat between liquid and liquid.

Referring to fig. 1, it can be understood that the first evaporator 109 is located in the air-conditioning refrigeration chamber 102 for reducing the air temperature in the air-conditioning refrigeration chamber 102; the second evaporator 113 is provided at the refrigerating compartment 103 for achieving refrigeration of the refrigerating compartment 103 of the refrigerator; the third evaporator 115 is provided at the freezing chamber 104 for achieving refrigeration of the freezing chamber 104 of the refrigerator.

The air-conditioning loop, the refrigerating loop and the freezing loop of the embodiment of the utility model share one compressor 105, three circulation loops are formed by the switch valve 106 and the three-way valve 111, the air-conditioning refrigeration, the refrigerating chamber 103 and the freezing chamber 104 are adjusted and controlled, the temperature of each chamber is convenient to control, the cost is saved, and meanwhile, the occupied space can be reduced.

The refrigerator and air conditioner all-in-one machine enables a user to have a comfortable kitchen cooking environment, and meanwhile, the refrigerator and air conditioner all-in-one machine does not need an air conditioner external unit and only needs one compressor 105, so that the refrigerator and air conditioner all-in-one machine is more efficient and energy-saving, saves space and reduces material cost; and the installation is carried out without an external machine, so that a professional is not required to go to the door for installation, and the installation cost is saved.

Referring to fig. 2, it can be understood that the integrated refrigerator-air conditioner further comprises a water tank 201 and a water pump 202, the water pump 202 is located in the water tank 201, the water tank 201 is placed in a small chamber of the refrigerating chamber 103, water in the water tank 201 can be cooled and stored in the small chamber under the low-temperature environment of the refrigerating chamber 103, and when the water tank exchanges heat with a refrigerant, the temperature difference is larger, the heat exchange efficiency is higher, and the cooling effect of the integrated refrigerator-air conditioner is better.

Referring to fig. 2, it can be understood that the plate heat exchanger 107 is located in the air-conditioning refrigeration chamber 102, and the plate heat exchanger 107 includes four interfaces a, b, c, and d, and the four interfaces a, b, c, and d are respectively and correspondingly connected to the water inlet pipe 203, the refrigerant outlet pipe 204, the water outlet pipe 205, and the refrigerant inlet pipe 206.

It should be noted that, because the air conditioning circuit does not share one condenser 110 with the refrigeration circuit and the freezing circuit, but only uses one plate heat exchanger 107, the load of the condenser 110 can be reduced, so that when the air conditioning function of the refrigerator-air conditioner all-in-one machine is turned on, the influence on the refrigerator function is reduced, and the refrigeration effect of the air conditioning function is better. When the air conditioning circuit, the refrigerating circuit and the freezing circuit share one condenser 110, the heat dissipation capacity of the condenser 110 is constant, and the refrigerator and the air conditioning function are simultaneously started, the heat dissipation capacity of the condenser 110 is insufficient, so that the refrigeration effect is reduced. Moreover, the condenser 110 is generally only arranged on the back of the integrated refrigerator-air conditioner, and if the heat dissipation capability of the condenser 110 is to be improved, the condenser 110 may be arranged on the side of the integrated refrigerator-air conditioner, so that a sufficiently large heat dissipation space needs to be reserved on the peripheral side of the integrated refrigerator-air conditioner, and the requirement on the living space of a user becomes high.
