Abstract

The invention relates to an air source heat pump unit in continuous heat supplying. The air source heat pump unit in continuous heat supplying comprises a compressor unit, an indoor water heat exchanging unit, a quasi-second level compression unit, an outdoor air heat exchanging unit and a defrosting branch circuit unit; due to the comprehensive technical scheme with quasi-second level compressioncombined with the temporal and spatial segmentation principle, on one hand, a compressor is additionally provided with a gas supplementing port, and a middle plate type heat exchanger is additionallyarranged in the system so that a quasi-second level compression heat pump cycle can be formed; and on the other hand, an air source heat pump outdoor air heat exchanger is arranged into at least twobranch circuit heat taking and defrosting systems capable of independently running, a fluorine-air heat exchanging mechanism in each branch circuit is subjected to defrosting operation in turns one byone, and therefore in-turn accurate defrosting and continuous heat supplying are achieved.

Description

technical field [0001] The invention relates to an air source heat pump unit, in particular to an air source heat pump unit for continuous heat supply. Background technique [0002] The air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a form of heat pump. The air source heat pump has a wide range of applications, can run all year round, does not need special personnel to guard, has low operating costs, and has outstanding energy-saving effects. It is an environmentally friendly product. It does not emit pollutants during operation, and at the same time, it will not cause damage to the human body, and has good social benefits. Therefore, it is widely used in heating and cooling in cold winter and hot summer areas in my country. [0003] However, in the cold northern region (Huaihe River), as the outdoor temperature decreases, the application of air source heat pumps h...
