Problems solved by technology

[0003] However, the current air-energy water heaters mainly use a single-stage vapor compression cycle. Because the temperature that can be absorbed in the air contains sensible heat and latent heat as the ambient temperature and humidity change, sensible heat can make people have obvious changes in cold and heat. Feeling; latent heat means that in the process of an object absorbing or releasing heat, its phase state has changed (such as a gas into a liquid), but the temperature does not change. This absorbed or released heat is called "latent heat", and through a single-stage steam The compression cycle generally adjusts the working speed of the compressor according to the ambient temperature. If the temperature is low, the working speed will be fast; Energy-saving effect

Description

technical field [0001] The invention relates to the technical field of air energy water heater control, in particular to an air energy water heater system and a control method. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, people have more and more requirements for the living environment. While improving the indoor water temperature, air energy water heaters have also greatly increased energy consumption. As we all know, an air energy water heater is composed of a compressor, a water tank, a throttling device and an evaporator, and a condenser is arranged in the water tank. The air energy water heater uses the working principle of the heat pump. The heat exchange medium absorbs the low-energy heat in the air in the evaporator, and is compressed into a high-temperature gas by the compressor. The water in the water tank is heated through the pipeline circulation system. The air-energy water heater ...
