Central air conditioning, air-purifying technology used broadly divided into the following categories, they have their own strengths, and with advances in technology continue to improve. 5. Electrostatic purifier advantages: electrostatic precipitator tungsten continuous release of High Voltage Electrostatic central air disinfection device company, so with the air in the dust and bacteria are put positive charge, then the negative electrode plate adsorption. You can filter smaller than cell dust, smoke. Comprehensive respiratory protection central air disinfection device design, and greatly reduce the risk of cancer. Easy to use, two weeks after use, it can clean dust, reduce secondary pollution. Do not replace the high cost of consumables and can be static sterilization. Electrostatic tungsten high-voltage electrostatic release, instant kill bacteria, viruses, colds and prevent the elimination of all kinds of infectious diseases more effective. Disadvantages: If ozone release control is not good, easy to harm the human body. In addition, the electrode plates require periodic manual cleaning. To sum up, taking into account the subway car by ventilation standards, air volume inside the car can not be less than 8000 m3 / h, fresh air is not less than 2600 m3 / hour; in terms of purification efficiency or system maintenance, electrostatic dust Technology has a very clear technical advantages, but also from the economic performance analysis, also has obvious advantages. It will make use of the air conditioning system greatly reduces energy loss itself, is very suitable for a large amount of dust, air-conditioned subway car air purifiers and dust. People and the environment does not produce any secondary pollution, because when using plasma photocatalysts device disinfection device disinfection central air conditioning prices, house staff can normally flow in the air-conditioned rooms, it is the other method of disinfection purification technology can not be compared . This product has a low air resistance characteristics of the existing air-conditioning ventilation system running a small effect. Plasma, photocatalysis, electrostatic field multiple roles, so sterilization, dust, clean the effect is more reliable, thorough. As long as the return on the product outlet installed air conditioning system will be able to conduct a comprehensive sterilization, disinfection, purification. Shape having a small size, lightweight, simple installation features, without changing the structure of air-conditioning ventilation system. Wei-environment Technology Co., Ltd. - The Trinity semiconductor disinfection purification technology, first at home and abroad! . Modular design, different modules can be designed central air disinfection device air-conditioning system according to different specifications, and different air volume air conditioning ventilation system support. Are provided around filters: pre-filter for the protective effect of plasma field, post carbon fiber filter, whose role is to remove the plasma field is not divisible contaminants. The products use ultraviolet light emitted by the air plasma electric field under a nitrogen atom excitation - TiO2, eliminating the ultraviolet light source products in general use, and completely avoid the mercury UV lamp metal contamination because of breakage.
