Under the mixed operating mode of air conditioner refrigeration and domestic hot water preparation, when refrigeration load is great, the hot water preparation volume meets the requirements, can switch to independent refrigeration mode, and unnecessary heat of condensation is discharged to outdoor. When the refrigeration load is smaller, the redundant cold energy is discharged to the outside through the condenser 3 by switching the valve bank.
In this embodiment, after the auxiliary circulation loop for producing hot water is added, when the air-conditioning refrigeration and domestic hot water production are combined, as the temperature of the water in the water storage tank 6 rises, the heat exchange effect of the refrigerant and water can be weakened, and the refrigeration effect of the air-conditioning system is affected, heat exchange is performed between the first heat exchange pipeline 4 and the second heat exchange pipeline 11, the refrigerant in the first heat exchange pipeline 4 is cooled by using the low-temperature medium in the second heat exchange pipeline 11, the first heat exchange pipeline 4 and the second heat exchange pipeline 11 form an intermediate heat exchanger, and the heat exchange effect of the intermediate heat exchanger is utilized, so that the refrigeration capacity of the air conditioner is not affected, and the domestic hot water production efficiency is ensured.
In addition to the integrated circulation pipeline system, the utility model also provides an air conditioner including this integrated circulation pipeline system, this air conditioner is wall-hanging air conditioner or cabinet air conditioner.
