The invention discloses an air purification system based on air conditioner condensation heat recycling and regenerating and a running method of the air purification system. The system comprises a compressor, an air purification heat exchanger, an outdoor tube-fin-type heat exchanger, an indoor tube-fin-type heat exchanger, a throttling element, a four-way reversing valve, an electric check valve,fans, air valves and a purification air channel. According to the air purification system based on air conditioner condensation heat recycling and regenerating, the air purification part is additionally arranged on the basis of a common household air conditioner; in the air purification stage, purification treatment is conducted on air flowing through the air purification system through the adsorption effect of VOCs and formaldehyde adsorption materials which are applied to the surface of the air purification heat exchanger; and in the regenerating stage, heat needed by the desorption processof the adsorption materials is provided through condensation waste heat of the air conditioner, and air is exhausted out of a room. Therefore, continuous adsorption of indoor VOCs and formaldehyde can be achieved, and the indoor air quality can be improved; the adsorption materials are regenerated by effectively utilizing the condensation waste heat of the air conditioner, the recycling effect isachieved, and system energy consumption is reduced; and indoor air exchange can be conducted while exhausting is conducted in the regenerating process, and therefore the effect of improving the indoor air freshness is concurrently achieved.
Description
technical field [0001] The invention relates to the technical field of air purification, in particular to an air purification system based on air conditioner condensation heat recovery and regeneration and an operating method thereof. Background technique [0002] People spend more than 80% of their lives indoors, so indoor air quality will have a greater impact on people's quality of life. Low indoor air quality will reduce labor efficiency, and even endanger the health of occupants, resulting in a series of building-related diseases, such as allergic rhinitis, allergic pneumonia, asthma and so on. Among the harmful gases that affect indoor air quality, volatile organic compounds (VOCs) and formaldehyde account for a large proportion. [0003] In the current indoor purification technology, due to the advantages of low cost and no harmful by-products, the adsorption material is widely used in the market. However, due to the limited adsorption capacity of the adsorption mat...
