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. 3. UV lamp UV antivirus technology is the use of UV lamps emit UV-C to kill bacteria, viruses and other microorganisms, or loss of activity central air purification device that can be used for air, water and surface disinfection. Its economy is high, it has been widely used in water treatment, food and beverage, wine, and other fields, as well as hospitals and other places. However, the use of UV technology in the AHU, because the air flow rate is too high (usually 2-3 m3 / s) can not achieve the desired purification effect, and the tube surface can easily be covered with dust and useless. Therefore, within the larger dust subway cars UV lamp technology is not applicable. Wei, a VBK-G-duct air purification device today we will stop here, there will be follow-up after another supplement, please continue to care a great environment! Wei, a central air purification system designed for air-conditioned terminal fan coil or wind machines and development of products, combined with different wind, wind speed, different forms of air conditioning systems. Installation instructions: The series of air purification disinfection sterilization equipment compact design, easy installation, installation staff determine where the actual size and power position of the pipe. According to interior purification scale, area, storey, air-conditioned air volume selection of the combination product. The series power consumption is very small, their work may lead to the 220V power supply from the fan coil control power supply, purification equipment work as central air purification devices Power Which is good, so purification equipment and air-conditioned indoor fan interlock control central air conditioning purification equipment price, easy operation and manipulation, and the same treatment. . Does not have any effect on the air conditioning system central air purification device customization, no need to change the air conditioning of the original parameters can be directly installed in the air supply duct or return air duct with rivets or self-tapping screws on both the product fixed duct . Small size, convenient installation, no additional power supply (power take in air conditioner), co-produced for installation in all types need air conditioning duct ends occasion, Wei, a central air conditioning and cleaning device is mainly installed in the fan coil or duct Machine return air box, and a central air conditioning and cleaning Wai device is mainly installed in the air duct.
