Problems solved by technology

During the cooling operation in summer, the air source heat pump air conditioner needs to discharge a large amount of condensation heat to the outdoor atmosphere when it is operating to cool the room, which will cause energy loss and environmental thermal pollution.
When heating in winter, the working efficiency of the air source heat pump air conditioner decreases sharply. When the temperature drops to a certain level, the air source heat pump air conditioner can hardly work normally. Therefore, the use of air source heat pump air conditioners in low temperature areas in winter has poor economic benefits and Difficulty running etc.
[0003] If air source heat pump air conditioners and heat pump water heaters are installed at the same time in commercial buildings or residential buildings, it will increase the overall equipment cost, operating cost and occupied space of the building.

Compared with the prior art, the present invention has reliable performance, high operation efficiency, high energy utilization rate and less thermal pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of air compression refrigeration and air conditioning, and more specifically, belongs to a vapor compression and low-temperature heat source hybrid heat pump device system that utilizes energy in the air for refrigeration, heating and domestic hot water supply. Background technique [0002] The air-source heat pump air-conditioning device adopts a vapor compression refrigeration cycle system. The vapor compression refrigeration cycle system usually uses the low-grade energy in the outdoor atmosphere to provide thermal equipment for the air-conditioning system as a cold and heat source. At present, air-source heat pumps have been used in residential and commercial buildings. Has been widely used. The air source heat pump air conditioner can produce cold water and hot water, and use cold water or hot water as the medium to directly deliver cold or hot air to the room through the air conditioner terminal, and p...
