Central air conditioning, air-purifying technology used broadly divided into the following central air conditioning air disinfection quotes, they have their own strengths, and with advances in technology continue to improve. 1. Activated carbon adsorption filter advantages: Activated carbon is a porous carbonaceous material, has a highly developed pore structure, the porous structure of activated carbon to provide a large surface area, can fully contact with the gas (impurities), giving the specific adsorption properties of activated carbon, making it very easy to achieve the purpose of the collection of impurities. Disadvantages: Ordinary charcoal does not adsorb all the toxic gas, low efficiency, easy desorption, large wind resistance. 2.HEPA net mechanical filter advantages: HEPA, Chinese meaning high efficiency air filters, to HEPA standard filter for particles 0.3 micron 99.99% efficiency, characteristics of HEPA air network is through, but small particles but it can not pass. HEPA filter by the Asian glass fiber membrane folded around a stack of continuous structure, forming a wavy washer is used to place and support the filter media. Disadvantages: filters need regular cleaning or updating, the higher cost of late. Today we will stop here in Central Air Conditioning disinfection process, there will be follow-up after another supplement, please continue to take care of a central air conditioning Wei dynamic sterilization system uses air-conditioning at the end really a aerodynamic devices forced transmigration of indoor air, indoor air by Core components - central air conditioning air blower sterilization disinfection, sterilization fans arranged in a special combination of high-intensity UV lamp, under ultraviolet light irradiation intensity fair, with a special calculation designed to achieve instant sterilization. . Central air conditioning system with dynamic sterilization installation simple convenient, fast and efficient sterilization, simple manipulation of security, in particular the use of low cost, etc., but also the reality of the dynamic maintenance of the air conditioning system. The system and assist in the activated carbon filter system, a negative oxygen ion generator means to achieve a sustained was sterilized under the premise of the indoor air (i.e., 'dynamic sterilized'), which can be achieved for medical sterilization purification level environmental requirements class II and having to get rid of the smell, fresh air.
