Air source solution type heat pump device

Abstract

An air source solution-type heat pump device, which relates to a heat pump heating method based on the principle that the solution absorbs energy from the air and a device for implementing the method. The device comprises a coolant circulation loop and a solution circulation loop. The coolant circulation loop comprises a compressor, two solenoid valves, a regenerator, a four-way valve, a first heat exchanger, four one-way valves, a reservoir, a filter, an electronic expansion valve, a secondary heat exchanger, a gas-liquid separator and connecting tubes thereof. The solution circulation loop comprises a , a solution container, three manual valves, a frequency-variable pump, an electric three-way regulating valve, an regenerator, a second heat exchanger and connecting tubes thereof. The invention solves the problems that the water-cooling unit is not used in winter, the air source heat pump has poor refrigeration performance in summer (compared with the water-cooling unit) and has high risk of frost formation in winter. The device is a novel air source solution-type heat pump heating device capable of the water-cooling refrigeration in summer and the solution-based air heat absorption in winter.

Description

technical field [0001] The invention relates to a novel heat pump heating method based on solution absorbing heat from the air and a device for realizing the method, which belongs to the technical field of refrigeration and air-conditioning system design and manufacture. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, people have higher and higher requirements for the comfort of living and working environments. Air conditioning has become an indispensable necessity for people's normal life, work and study. The central air-conditioning system of existing buildings mostly uses water-cooled chillers for cooling in summer. In winter, the water-cooled chillers stop using because they cannot heat, resulting in a large number of idle equipment. At the same time, the central air-conditioning system adopts a boiler heating scheme for heating, but this increases the initial investment and hea...
