Building integrated solar air source heat pump unit

Abstract

The invention relates to a solar air source heat pump unit capable of realizing building integration, which comprises a refrigerant circulation loop and a solar energy cold and hot water loop; wherein in the refrigerant circulation loop, the output end of a compressor (1) is divided into two ways, one way is connected with a first input end (2a) of a four-way valve, and the other way is connectedwith the output end (3b) of a first heat exchanger through a defrosting electromagnetic valve (28) and a defrosting throttle valve (29); in the solar energy cold and hot water loop, a cold and hot water return end is divided into three ways: one way is connected with the input end of a seventh electromagnetic valve (23) through a sixth electromagnetic valve (22); the second way is connected with a second input end (12c) of a second heat exchanger through a first electromagnetic valve (14); the third way is divided into two ways again after being combined with the second output end (12d) of the second heat exchanger through a second electromagnetic valve (15). The invention can realize seamless abutting joint of solar energy and an air source heat pump, and completely solves the problems of the intermittence and the instability of solar energy heating supply.

Description

technical field

[0001] The invention relates to a device that organically combines solar energy with an air source heat pump, realizes efficient utilization of solar energy and integration of buildings, and provides heating for buildings.
