Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to a refrigerant-to-water air source heat pump system. Background Art
[0002] At present, for the refrigerant-to-water units on the market, a water-side heat exchanger is added to the multi-connected system. As one of the indoor units, when there is a demand for making hot water, the water-side heat exchanger acts as a condenser to make hot water, realizing the function of making hot water by the unit. The main problems existing in the above scheme are as follows: As a part of the unit system, the water-side heat exchanger will store a certain amount of refrigerant, which affects the air-conditioning cooling and heating performance of the unit; in the selection of the refrigerant amount, only a compromise is made among the three functions of air-conditioning cooling, heating, and making hot water, and the refrigerant demand for each part function cannot be optimized. Content of the Utility Model
[0003] The utility model provides a refrigerant-to-water air source heat pump system, which solves the problem of low performance caused by the inability to optimize the refrigerant amount in the three functional blocks of refrigeration, heating, and making hot water of the existing refrigerant-to-water air source heat pump system.
[0004] To achieve the above object, the utility model provides the following technical solution: A refrigerant-to-water air source heat pump system includes a compressor, a four-way reversing valve, a water-side solenoid valve, a water-side heat exchanger, a liquid receiver, a water-side electronic expansion valve, an outdoor-side electronic expansion valve, an outdoor-side heat exchanger, a gas-liquid separator, an air-side solenoid valve, and an indoor unit assembly. The compressor is connected to the four-way reversing valve and the gas-liquid separator. The four-way reversing valve is also connected to the gas-liquid separator, the outdoor-side heat exchanger, the water-side solenoid valve, and the air-side solenoid valve. The water-side solenoid valve is connected to the water-side heat exchanger. The water-side heat exchanger is also connected to the liquid receiver. The liquid receiver is also connected to the water-side electronic expansion valve. The water-side electronic expansion valve is also connected to the outdoor-side electronic expansion valve and the indoor unit assembly. The indoor unit assembly is also connected to the air-side solenoid valve.
[0005] Preferably, the indoor unit assembly includes a plurality of parallel-connected indoor units. Each indoor unit includes an indoor-side heat exchanger and an indoor-side electronic expansion valve connected to the indoor-side heat exchanger.
[0006] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0007] When making hot water, the refrigerant supply to the indoor unit assembly is cut off through the indoor-side solenoid valve and the indoor-side electronic expansion valve. The liquid receiver is included in the function of making hot water and is used to adjust the excess refrigerant amount, avoiding the low performance caused by too much refrigerant in the system.
[0008] When the air conditioner is cooling or heating, the refrigerant supply to the water-side heat exchanger and the accumulator is cut off by the water-side electronic expansion valve and the water-side solenoid valve, reducing the refrigerant in the water-side heat exchanger and the accumulator and avoiding low performance of the system caused by too little refrigerant.

[0017] As Figure 2 shown, the hot water heating operation principle of the Tianfu-Dishui air source heat pump system in this embodiment: The refrigerant is compressed by the compressor 1 into a high-temperature and high-pressure refrigerant gas, passes through the four-way reversing valve 2 and the water-side solenoid valve 3 and enters the water-side heat exchanger, exchanges heat with water in the water-side heat exchanger 4 and becomes a medium-temperature and high-pressure refrigerant liquid, then passes through the liquid receiver 5 to store the excess refrigerant in the system, and then the refrigerant liquid sequentially passes through the water-side electronic expansion valve 6 and the outdoor-side electronic expansion valve 7, becomes a low-temperature and low-pressure refrigerant liquid. The low-temperature and low-pressure refrigerant liquid exchanges heat with air through the outdoor-side heat exchanger 8 and becomes a low-temperature and low-pressure refrigerant gas.
