Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air source heat pumps, in particular to a filter applied to an air source heat pump system. Background Art
[0002] With the continuous development of energy technology, air source heat pump system has been widely used in various buildings and places as an efficient and environmentally friendly heating and cooling air conditioning solution. Its core working principle is to achieve heating or cooling function by absorbing heat energy from the environment through heat exchange and compression cycle. However, in actual use, dust, particulate matter and other impurities in the air often enter the heat pump system with the flow of air, especially at the air inlet and the surface of the heat exchanger. These impurities will accumulate in large quantities, seriously affecting the heat exchange efficiency and operation stability of the system.
[0003] To solve this problem, traditional air source heat pump systems are usually equipped with filters to intercept and remove impurities entering the system. However, traditional filters often simply block impurities and cannot effectively remove attached dirt. As time accumulates, the filter itself will gradually become clogged and need to be manually cleaned or replaced, which not only increases maintenance costs, but also affects the continuous and stable operation of the system.
[0004] Therefore, developing a filter that can automatically clean and continuously maintain high-efficiency filtering performance has become an important research direction for improving the performance and reliability of air source heat pump systems. This self-cleaning filter needs to be able to automatically remove dirt and impurities on the filter surface without affecting the normal operation of the system, thereby keeping the filter unobstructed and efficient.
[0005] At present, although there are some filter products with self-cleaning function on the market, most of them have problems such as poor cleaning effect, high energy consumption, and complex structure, which makes it difficult to meet the requirements of air source heat pump system for high efficiency, stability, and environmental protection. Therefore, developing a self-cleaning filter with simple structure, good cleaning effect, and low energy consumption has important practical application value for improving the overall performance of air source heat pump system.
