Description

technical field [0001] The invention belongs to the technical field of air-conditioning systems for supplying treated primary air from one or more central stations to distribution units in rooms or places where secondary treatment can be obtained, and in particular relates to treating air other than heating and cooling for Characteristic purification treatment device. technical background [0002] The pollution of central air-conditioning has become a major problem of environmental pollution in the world. Since the 1970s in the United States, a large area of ​​"Legionella" group cross-contamination was caused by central air-conditioning, resulting in nearly 100 deaths. It has been reported that central air-conditioning has become an important source of indoor air pollution, and the resulting pollution may lead to the spread of large-scale mass germs. For this reason, my country promulgated "Indoor Air Quality Standards" in 2003, and the Ministry of Health also promulgated "...
