Abstract

The invention discloses an air-circulating open-type heat pump heat-supply method. Cold air in an atmospheric environment is preheated in a heat regenerator prior to entering a first air compressor and is discharged from a discharging end after compression heating-up; discharged air is divided into two branches, one branch of the air enters a second air compressor and then enters a first inlet ofan air tee joint after compression heating-up and pressure rise; the other branch of the air enters an air pressing part and then enters a second inlet of the air tee joint after compression heating-up and pressure rise; the two branches of air are mixed in the air tee joint prior to entering an air / water heat exchanger through an air inlet pipe of the air / water heat exchanger; high-temperature high-pressure air heats circulating water in a water pipeline in the air / water heat exchanger. By one-stage preheating and two-stage compression for preparation of high-temperature air, heating of circulating water is completed through heat exchange, and preparation of hot water at 60DEG C or above for daily life and building heat supply in cold and severe cold regions can be realized.

Description

technical field [0001] The invention relates to a hot water preparation method, in particular to a heat supply method of an open heat pump with air circulation. Background technique [0002] More and more studies have shown that industrial emissions and the extensive use of fossil fuels for heating are important reasons for the frequent and increasingly severe smog in northern China in recent years. Gradually reducing the use of fossil energy, increasing the utilization rate of renewable energy, and promoting clean heating in winter in the northern region are the inevitable development direction of building heating in the future, and it is a practice to solve social contradictions in our country. Among various heating methods, heat pump heating is a heating method that basically does not produce pollution and has a relatively high energy utilization rate, and has attracted much attention in recent years. [0003] Among various types of heat pumps, reverse Brayton cycle (air...
