Embodiment 1
[0072] Embodiment 1 and Embodiment 2 are cooling-only structures, and Embodiment 3 and Embodiment 4 can both cool and heat. Now take Embodiment 4 as an example to illustrate the working process, and the working process and implementation of other embodiments Example 4 is the same, or part of Example 4.
[0073] In the actual application process, during refrigeration, the high-temperature and high-pressure superheated gaseous refrigerant discharged from the compressor 2 first passes through the hot water side heat exchanger 1 for sensible heat exchange, and the refrigerant coming out of the hot water side heat exchanger 1 passes through the high pressure side gas After the liquid separator 7, the gaseous refrigerant is discharged into the four-way reversing valve 6 from the upper side, and the liquid refrigerant is discharged from the lower side through the first electromagnetic valve 8 and enters the high-pressure side liquid reservoir 11, and the gaseous refrigerant coming out...

The invention provides a heat recovery unit system for an air-cooled part and a control mode and belongs to the field of air conditioning systems. The system comprises a compressor, a hot water side heat exchanger, a high pressure side gas-liquid separator, an air side heat exchanger and an air-conditioning water side heat exchanger, a first branch, a second branch and a fifth branch, wherein a medium flows to the air-conditioning water side heat exchanger from the compressor by successively passing through the hot water side heat exchanger, the high pressure side gas-liquid separator and an electronic expansion valve, and a first electromagnetic valve is arranged on the first branch; the medium flows to the air-conditioning water side heat exchanger from the compressor by successively passing through the hot water side heat exchanger, the high pressure side gas-liquid separator, the air side heat exchanger and the electronic expansion valve, a throttling capillary tube is arranged inparallel to the electronic expansion valve, and a second electromagnetic valve is arranged on the branch where the throttling capillary tube is arranged; and a medium flows from the air-conditioning water side heat exchanger back to the compressor. According to the heat recovery unit system, the compressor is stable, and a problem of low voltage trip is unlikely to happen.
Description
technical field [0001] The invention belongs to the field of air-conditioning systems, and relates to a heat recovery unit system of an air-cooled part and a control method. Background technique [0002] At present, some heat recovery units of air-cooled modular units will have various problems during actual operation, mainly including the following situations: (1) During cooling operation, 1. When the ambient temperature is high and the heat recovery water temperature is low, it will cause The heat exchange capacity of the finned tube heat exchanger (condenser) is weakened, but the heat exchange capacity of the heat recovery heat exchanger is improved. It is overcooled to the wet saturation area, so the refrigerant coming out of the heat recovery heat exchanger is in a gas-liquid mixed state. For the heat pump unit, on the one hand, when the refrigerant coming out of the heat recovery heat exchanger passes through the four-way reversing valve, Since the refrigerant is in a...
