Abstract

The invention relates to an air heat pump heating cycle system, belonging to the heating technique, which can be used in water heater and air conditioner. It comprises a compressor (1), a heat exchanger (2), a throttle device (3), an evaporator (4), a liquid storage device (5), the first electromagnetic valve (7), the first second electromagnetic valve (8), and a auxiliary evaporator (9) between the evaporator (4) and the liquid storage device (5). The invention has the defrosting function without stopping the compressor and it can effectively avoid the damage on the device and the impact on the electric network caused by repeatedly switching the compressor. And since it adsorbs the heat from the air to defrost, it can avoid the time for balancing the pressure to improve its efficiency.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to an air energy heat pump heating cycle system, which can be widely used in water heaters and air conditioners. Background technique [0002] Heat pump technology is a new energy technology that has been receiving great attention from experts and scholars around the world. Air energy heat pump water heaters are an application of heat pump technology in the production of hot water. Traditional water heaters (electric water heaters, fuel oil, gas water heaters) have large energy consumption, High cost, serious pollution and other disadvantages; the operation of energy-saving and environmentally friendly solar water heaters is restricted by meteorological conditions; the heating principle of heat pump water heaters is completely different from traditional solar water heaters, using air, water, solar energy, etc. as low-temperature heat sources, and electricity The air energy heat pump...
