Description

Technical Field

[0001] The utility model relates to the technical field of air energy water heating systems, in particular to an air energy water heating system with high heat conversion efficiency. Background Art

[0002] Air energy water heater, also known as "air source heat pump water heater", has a working principle very similar to that of air conditioner. It uses a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into gas in the evaporator after passing through the expansion valve, and absorbs a large amount of heat energy from the air; the gaseous working fluid is compressed by the compressor into a high-temperature, high-pressure liquid, and then enters the condenser to release heat and heat the water... This continuous cycle of heating can heat the water to 50℃~65℃. Air-energy water heaters are generally installed on the roof, with the air-energy main unit and the water tank separated. Cold water is added to the bottom of the water tank, and hot water comes out from the outlet at the top after heat exchange. Because the heat exchange is always carried out in the water tank, cold water has to be added all the time when hot water is used. When the amount of hot water used is greater than the amount of cold water heat exchange, the hot water temperature will drop sharply. In order to meet people's normal use, electric heating rods can only be used in the water tank for auxiliary heating, which leads to increased energy consumption and reduced overall heat conversion efficiency of the air-energy water heater. In addition, in some places where a large amount of hot water is needed, an insulated water storage tank is also provided. The insulated water storage tank is connected to the heat exchange water tank through a pipe to transport hot water. When the hot water transport pipe is too long or the outdoor temperature is too low, some heat will be lost in the hot water transport process. In order to maintain the hot water temperature, heat exchange can only be carried out continuously, further reducing the heat conversion efficiency of the air-energy water heater. In addition, the outdoor temperature is very low in the winter in the north, and the heat dissipation fins of the air-energy main unit are prone to frost, which seriously affects the heat conversion efficiency of the air-energy water heater system.
