Central air conditioner with purification function

Abstract

The invention discloses a central air conditioner with a purification function. The central air conditioner comprises an outdoor unit, a plurality of indoor units and a distributor, wherein the outdoor unit is provided with an outdoor heat exchanger and carries out heat exchange with outdoor air; the indoor units are provided with indoor heat exchangers and carry out heat exchange with the indoor air, and the distributor controls refrigerants between the outdoor unit and the indoor units to flow; and a plurality of electromagnetic expansion valves for adjusting the flow of the refrigerants and a plurality of noise eliminators for removing the noise are arranged inside the distributor; and the central air conditioner is characterized in that filtering purification units are arranged at a fresh air opening and in an air returning pipeline of the central air conditioner, and each filtering purification unit comprises a first adsorption component, a catalyst component and a second adsorption component which are overlapped in a front-and-back manner; and after removal of catalysts for benzene, methylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in air of the building, the concentration reaches below 0.05 mg / cubic meter, and meanwhile, the content of microorganisms in the circulating air can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a central air conditioner with a purification function. Background technique [0002] At present, with the development of the economy, there are fewer and fewer plots available for civil construction in major cities in China, the average height of buildings is increasing year by year, and a large number of office buildings are increasing rapidly. In office buildings, central air conditioners are generally installed. [0003] The central air-conditioning system is mainly composed of refrigeration and heating equipment or devices (compressors, compression condensing units, water chillers, air-conditioning boxes, boilers, spray rooms, etc.), pipelines (refrigerant pipelines, refrigerant pipelines, refrigerant pipelines) etc.), indoor terminal equipment (indoor air ducts, water pipes, diffusers, fan coil units, air-conditioning indoor units, etc.), outdoor equipment (outdoo...

Problems solved by technology

[0006] In office buildings, due to the large number of people and the large building area, it is difficult to avoid various decoration pollution, respiratory exhaust gas pollution, and germ transmission pollution, and the central air conditioners used in most office buildings are return air, which leads to pollution in some areas through the central air conditioner. Air conditioning diffuses throughout the building and, in the event of an epidemic, can lead to a rapid spread of disease
