Central air conditioner for air sterilization and purification

Abstract

The invention belongs to the technical field of air sterilization and purification, in particular to a central air conditioner for air sterilization and purification. The central air conditioner comprises a main air conditioner, a plasma reactor, a pulse power source, a main fan, a return air fan, a controller, a fresh air opening, an air outlet and a ventilating duct, wherein a positive electrode and a negative electrode are arranged in the plasma reactor, the positive electrode is formed by arranging a plurality of oxidation resistant metal bands in the same plane in parallel, and the negative electrode is made of an aluminum plate or a stainless steel plate; a conductor rail for preventing micro-discharge, which is made of aluminum bars or stainless steel strips, is also arranged in the plasma reactor; and the two ends of the positive electrode are respectively fixed on the conductor rail for preventing micro-discharge. The central air conditioner of the invention not only can regulate indoor temperature and humidity but also can efficiently sterilize bacteria and viruses, degrade TVOC, eliminate foreign taste and remove granular aerosol, and has the advantages of energy savingand good reliability. The central air conditioner is specially designed for air sterilization and purification of public places such as hospitals, clean rooms, office buildings, markets, hotels, subways and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to a central air conditioner for air disinfection and purification. Background technique: [0002] With the development of society and the advancement of science and technology, people's living standards continue to improve, making various types of central air conditioners quickly enter public places such as hospitals, clean rooms, office buildings, shopping malls, hotels, theaters, airports, subways and underground buildings. , using central air conditioning to adjust temperature, humidity and cleanliness, creating a comfortable indoor environment for people. All kinds of buildings are mostly closed, indoor electrical equipment, decoration materials and personnel activities produce harmful gases, viruses, bacteria and aerosols and other pollutants, causing many people to suffer from eye and throat irritation, nasal congestion, headache, dizzin...

AI Technical Summary

Problems solved by technology

[0008] Disadvantages: Ozone is a strong oxidant, so it should not be used in places where there is direct contact with flammable and explosive gases; the penetrating power of ozone is weak, the ability to kill bacteria in the depth of the object is low, and it cannot collect dust

[0011] The main disadvantages are: ultraviolet rays are invisible light, easy to leak, and cause damage to human eyes and skin; the working life of ultraviolet lamps is only 8000 hours

The problem is that the 100m3 room meets the Ministry of Health’s Class II environmental standards for hospitals. The energy consumption of ultraviolet rays and ozone to achieve the same disinfection effect is similar, which is 160-240W; especially the existence of the above defects, which is also the reason why hospitals seldom use them.

The disadvantage is that it is sharp discharge, uneven discharge, low ability to decompose harmful bacteria, viruses and organic pollutants in the air, and secondary pollution
