Problems solved by technology

[0003] In order to solve the problem of insufficient building heating and domestic hot water preparation methods in cold and severe cold areas, the present invention provides a closed heat pump water heating device based on air circulation. The device uses two-stage preheating and two-stage compression to provide high-temperature air. The heat exchanger completes the heating of the circulating water, which can prepare building heating water and domestic hot water above 60°C in cold and severe cold regions

Embodiment Construction

[0022] Closed heat pump water heating device based on air circulation, including the first air compressor 1, the turbine compressor part 2, the second air compressor 3, the regenerator 4, the air / water heat exchanger 5, and the air / air heat exchanger 10 and air check valve 11; the turbine compressor part includes a turbine part 202 and a compressor part 201; the air discharged from the exhaust end of the turbine part enters the air / air heat exchanger 10, exchanges heat with the air in the atmospheric environment, and absorbs heat It enters the regenerator 4 through the air pipe, and after further absorbing heat, it is discharged from the first exhaust end of the regenerator, and then divided into two routes. The air compressor 1 is compressed and heated and discharged from the exhaust end; the second air enters the compressor part 201 of the turbine compressor part 2, is compressed by the compressor part 201, and is discharged from the exhaust end after being heated and boosted...

Abstract

The invention provides a closed type heat pump water heating device based on air circulation. According to the device, an air / air heat exchanger and a heat return device are utilized for carrying outtwo-level preheating on air, then a first air compressor, an air compressing part and a second air compressor carry out two-level compressing on the air, high-temperature air is obtained, heating of circular water is completed by means of the heat exchanger, and water for building heating and domestic hot water with the temperature above 60 DEG C can be prepared in cold and severe cold areas.

Description

technical field [0001] The invention relates to a hot water preparation device, in particular to a closed heat pump water heating device based on air circulation. Background technique [0002] Industrial emissions in modern society and the extensive use of fossil fuels for heating have led to frequent smog in northern China in recent years. People are beginning to pay attention to the utilization of clean energy, among which heat pump equipment is a kind of energy-efficient equipment that does not generate local pollution and is favored by more and more people. However, traditional vapor compression electric heat pumps mostly use freon refrigerants. As people's requirements for ozone layer protection and global warming become more and more concerned, chlorofluorocarbons (CFCs) refrigerants have been eliminated and used in Transitional HCFCs refrigerants are also increasingly regulated. In addition, for the traditional vapor compression heat pump, there is a problem that th...
