2021 High quality Pressure Step Control - Purifying fresh air unit – TekMax

The fresh air unit is an air conditioning equipment that provides fresh air. It is an efficient, energy-saving, and environmentally-friendly all-round ventilation fresh air system. It is used in office buildings, hospitals, hotels, stations, airports, residences, villas, entertainment venues, etc. Has a wide range of installation and application. The working principle is to extract fresh air from the outdoors after dust removal, dehumidification (or humidification), cooling (or heating), etc., and then send it to the room through a fan, and replace the original indoor air when it enters the indoor space.

The main function of the fresh air unit is to provide constant temperature and humidity air or fresh air for the air-conditioned area. Fresh air unit control includes supply air temperature control, supply air relative humidity control, antifreeze control, carbon dioxide concentration control, and various interlocking controls, etc.

The fresh air system is based on the use of special equipment on one side of a closed room to send fresh air to the room, and then discharge from the other side to the outdoors by special equipment, forming a “fresh air flow field” indoors to meet the needs of indoor fresh air ventilation.

The implementation plan is to use high wind pressure and large flow fans, relying on mechanical strength to supply air from one side to the room, and from the other side to use a specially designed exhaust fan to discharge to the outside, forcing a fresh air flow field to be formed in the system. While supplying air, the air entering the room is filtered, disinfected, sterilized, oxygenated, and preheated.
