Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, and particularly relates to an air source heat pump self-cleaning water tank. Background Technique

[0002] With the wide application of air source heat pump technology, its performance stability and operation efficiency have become the focus of user attention. As a key component in the air source heat pump system, the water tank not only undertakes the functions of storing and supplying hot water, but also directly affects the operation effect of the entire system. However, traditional water tank designs often lack consideration for self-cleaning functions, making it easy for the water tank to accumulate scale, microorganisms and other pollutants during long-term use, thereby affecting water quality and use effects.

[0003] During the actual operation process, due to the influence of water quality and environmental factors, scale and microbial growth are likely to occur inside the water tank. The accumulation of scale will not only reduce the water storage capacity and heat transfer efficiency of the water tank, but also may pollute the water quality and affect the health of users. At the same time, the growth of microorganisms may also cause peculiar smells inside the water tank and even pose a risk of disease transmission.

[0004] To solve this problem, there have been some attempts in the market to keep the water tank clean by adding chemical cleaning agents or regular manual cleaning. However, these methods have many deficiencies. Chemical cleaning agents may cause secondary pollution to the water quality and affect the health of users; while regular manual cleaning requires a lot of time and manpower, and the cleaning effect is difficult to guarantee.

[0005] Therefore, it is particularly important to develop a water tank for air source heat pumps with self-cleaning functions. Such a water tank can automatically remove internal pollutants during operation, keep the water quality clean and hygienic, and at the same time improve the operation efficiency and stability of the system.
