Abstract

The invention discloses an air supplement heat recovery heat pump device which is formed by connecting a first set of heat pump system, an air supplement system, a second set of heat pump system and a cooling-medium water system. The first set of heat pump system is formed by connecting a first compressor, a four-way reversing valve, a first heat exchanger, a second heat exchanger, a third heat exchanger, a second electronic expansion valve and an evaporator; the air supplement system is formed by connecting the second heat exchanger, an electromagnetic stop valve and a first electronic expansion valve; and the second set of heat pump system is formed by connecting the third heat exchanger, a third electronic expansion valve, the first heat exchanger and a second compressor. The invention can solve the problem of the prior art, ensure that a heat pump can be normally started in a low-temperature environment, effectively ensure the inspiratory capacity of the compressors, prevent the evaporator from frequently frosting and prevent overhigh temperature of exhaust, and ensure the heat pump to normally run to supply heat. In the invention, the heat of the heat pump systems can be used for supplying heat to the maximum extent so that the heating capacity and efficiency of heat supply of the heat pump can be greatly improved.

Description

technical field [0001] The invention relates to a heat pump device for replenishing air heat recovery. Background technique [0002] At present, all kinds of existing heat pump devices have the following deficiencies: it is difficult to start normally in the low-temperature environment in the first winter; to the role of heating in winter; the third heat pump system has low working efficiency. Contents of the invention [0003] The object of the present invention is to provide a heat pump device for supplementing air heat recovery, which can solve the problems existing in the prior art, can ensure the normal startup of the heat pump in a low-temperature environment, and can effectively ensure the air intake of the compressor to prevent Frequent frosting of the evaporator and high exhaust temperature enable the heat pump to operate normally for heating; it can also maximize the heat of the heat pump system for heating, which can greatly improve the heating capacity and eff...
