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 hot water preparation method with air circulation. The method provides high-temperature air through two-stage preheating and two-stage compression. 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

[0019] The air discharged from the exhaust end of the turbine component enters the air / air heat exchanger 10, exchanges heat with the air in the atmospheric environment, and enters the regenerator 4 through the air pipe after absorbing heat. After further heat absorption, the regenerator first The exhaust end is discharged, and then it is divided into two paths. The first path of air enters the intake end of the first air compressor 1, and is discharged from the exhaust end after being compressed and heated by the first air compressor 1; the second path of air enters the turbine compressor. The compressed air component 201 of component 2 is discharged from the exhaust end after being compressed by the compressed air component 201, heated up and boosted, and an air check valve 11 is set on the exhaust air pipeline; after the two-way exhaust is mixed through the air tee, it enters the second air compressor. The air intake end of the machine 3 is discharged from the exhaust end af...

Abstract

The invention provides an air-circular closed-type heat pump hot water making method. According to the method, an air / air heat exchanger and a heat regenerator are utilized to perform two-stage preheating on air; then the air is subjected to two-stage compression through a first air compressor and an air compression component as well as a second air compressor, so that high-temperature air is obtained; then circular water is heated through a heat exchanger; and building heating water and domestic hot water with the temperature above 60 DEG C can be made in cold and frigid regions.

Description

technical field [0001] The invention relates to a hot water preparation method, in particular to an air circulation closed heat pump hot water preparation method. 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...
