Dynamic filtering and static sterilizing and disinfecting air purifying system and method of central air conditioner

Abstract

The embodiment of the invention discloses a dynamic filtering and static sterilizing and disinfecting air purifying system and method of a central air conditioner. The system comprises first sterilizing, disinfecting and purifying equipment, second sterilizing, disinfecting and purifying equipment and air circulating equipment. The first sterilizing, disinfecting and purifying equipment and the second sterilizing, disinfecting and purifying equipment are arranged in parallel, and the first sterilizing, disinfecting and purifying equipment and the second sterilizing, disinfecting and purifyingequipment control respectively configured valves to be opened and closed correspondingly according to different operation procedures. The first sterilizing, disinfecting and purifying equipment and the second sterilizing, disinfecting and purifying equipment each comprise a filtering unit, an adsorbing and hindering unit, a static electret unit, a sterilizing and disinfecting unit and an internalair circulating unit. According to the scheme, the dynamic filtering and static sterilizing and disinfecting air purifying system and method are suitable for central air conditioner purifying systemsand space ventilating sites of different treatment scales, the defects of sterilizing and disinfecting devices of traditional central air conditioners and space ventilating sites are overcome, virusesand bacteria can be insulated from crowd activity spaces, and space safety is guaranteed; and cross infection is thoroughly avoided, the input cost is low, and system operation is safe and stable.

Description

Technical field [0001] The embodiments of the present application relate to the field of environmental protection technology, and in particular to a central air conditioning dynamic filtration, static sterilization and disinfection air purification system and method. Background technique [0002] Central air conditioning is composed of one or more heat and cold source systems and multiple air conditioning systems. Central air conditioners have corresponding air purification functions. When existing central air conditioners perform air purification, the fresh air and return air of the system are mixed and first enter the air filter to filter the dust particles and particles in the gas. The filtered clean air then enters The air conditioning processor performs heat exchange and cooling with the cooling medium, and turns it into air with a suitable temperature in the indoor space. It is distributed and transported to the required space through the air supply duct through the ai...
