Abstract

The invention relates to a filtration system for microorganisms such as legionella in an air duct of a central air conditioner and a filtering method thereof, and belongs to the field of air conditioning and purification. The filtration system is arranged at an entrance of a central air conditioner cabinet, a primary filtration device, a secondary filtration device and air dewater device and a cooling device are used. Hot water using solar energy and hot water flowing into a cooling tower as heat sources is used as a primary filtration device of the legionella, lithium chloride is used as a secondary filtration device of the legionella and dewater device of air, and cooling water flowing out of the cooling tower is used as a cooling device of air. The filtration system for the microorganisms such as the legionella in the air duct of the central air conditioner is high in integration level and good in filtering effect, and can effectively prevent the diffusion of bacteria and the microorganisms in a central air-conditioning system and can prevent the cooling and cracking of a coil pipe in the air-conditioning cabinet in winter.

Description

Technical field [0001] The invention relates to a microbial filtering system such as Legionella in a central air-conditioning duct and a filtering method thereof, belonging to the field of air conditioning and purification. Background technique [0002] With the development of science and technology and the improvement of personnel thermal comfort requirements, central air-conditioning systems are more and more common in the fields of office, residence, hotel, guesthouse and so on. With the increase in the number of central air conditioners, their maintenance time is often not very timely, which will lead to the growth of bacteria and pose a threat to human health. Among the bacteria that breed in central air conditioners, Legionella is the most harmful. Legionella, also known as "Legionella pneumophila", is a pathogen that easily causes diseases of the respiratory system, especially the lungs. Legionella bred in the air-conditioning water system is blown out by the cold a...
