What is the air disinfection and purification device for the central air-conditioning return air outlet?

Have done central air conditioning should be understood, because of different shapes and needs of several types, there are fan coils, there are new air outlets, return air outlets, pipeline, combined, wind cabinet, plug-in and so on. For these different air volumes, the air purifiers customized in size are matched with central air conditioners. What is the nature of this air purification device?

Have done central air conditioning should be understood, because of different shapes and needs of several types, there are fan coils, there are new air outlets, return air outlets, pipeline, combined, wind cabinet, plug-in and so on. For these different air volumes, the air purifiers customized in size are matched with central air conditioners. What is the nature of this air purification device?

Now, the air-conditioner electrostatic precipitator of the air-conditioner of the central air-conditioner is introduced as an example. The air-purifying device of the return air inlet is located at the return air outlet of the central air-conditioning. The return air: the air-conditioning system will purify the wind in the local environment and then return it to the local environment for a return air: In a centralized air treatment plant, part of the indoor air mixed with fresh air.
Secondary return air: indoor air that is remixed with treated mixed air in a centralized air handling unit

Essentially, when the high-voltage electrostatic field is energized, the air in the entire space flows to the return air outlet, and some harmful substances such as bacteria and viruses in the air are adsorbed onto the electrostatic field, and the instantaneous high voltage kills all of them. Ensure that the air passing through the return air is clean and fresh. After a return air process, the indoor air will be cleaned and disinfected again and again. Of course, after working for a certain period of time, it should be cleaned in time to avoid excessive dust and affect the purification effect.

Efficient dust removal and sterilization; captures 95% of the 0.3~0.5 micron particles in the passing air, kills more than 90% of fungi and viruses, effectively removes odor, smoke and has excellent performance.
Low resistance, low carbon, energy saving; pressure loss <25Pa at high wind speed
Tailor-made, intimate contact; ingeniously design the air volume and the size of the air duct, as close as possible to the sealing section; ensure the wind speed and reduce the dust on the heat exchanger of the ventilation system, maintaining a high heat exchange rate;
Permanent use of zero consumables, saving maintenance costs; integrated filter and electronic dust collection module integrated structure, easy to disassemble, clean, repeated use.
