Home air conditioning system capable of removing indoor vocs and formaldehyde and its operating method

Abstract

The invention discloses a domestic air conditioning system capable of removing indoor VOCs and formaldehyde and an operation method. The system comprises a compressor, a regenerative heat exchanger, an adsorption bed, an outdoor tube fin heat exchanger, an indoor tube fin heat exchanger, a throttling element, a four-way reversing valve, an electric check valve, a fan, an air valve and a purification air channel. According to the domestic air conditioning system, an air purification part is added on the basis of a common domestic air conditioner, and at the stage of air purification, flowing air is purified by VOCs filled in the adsorption bed and the adsorption of formaldehyde adsorbing materials; at the stage of regeneration, the air is heated in the regenerative heat exchanger by utilizing condensation waste heat of the air conditioner, high-temperature air enters the adsorption bed so as to supply heat required in a regenerative process of the adsorbing materials and act as sweep gas at the same time, and then exhaust air is discharged outdoors. According to the domestic air conditioning system, the indoor VOCs and formaldehyde can be continuously adsorbed, so that the indoor air quality is increased; the condensation waste heat of the air conditioner is effectively used so as to regenerate the adsorbing materials, so that the effect of recycling is achieved, and the energyconsumption of the system is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning, in particular to a household air conditioning system capable of removing indoor VOCs and formaldehyde and an operating method. 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 mate...

AI Technical Summary

Problems solved by technology

[0004] In conventional household air conditioning systems, the heat of condensation in the outdoor tube-fin heat exchanger is directly discharged to the outside in the form of waste heat through the fan, and this part of the heat has not been well utilized.
