air handing unit is a unit formed by integrally installing air filters, surface coolers, heaters, humidifiers, etc. in a vertical/horizontal cabinet type box body. It does not have a refrigerator, and provides cold and hot water by centralized cold and heat sources. Generally, the combined air conditioning unit is used in large occasions, which consists of several processing sections, such as fresh air section, mixing section, heating section, filtering section, surface cooling section, humidification section, etc. The air supply volume can reach 100,000 air volume, while the air handing unit is generally 2000-12000 air volume, and there are not many functional sections. If the air handing unit only processes outdoor air, it can be called fresh air unit, if it processes fresh air and indoor return air. Then it is an air handing units in the general sense. Therefore, on the whole, the combined air-conditioning unit has strict requirements on the temperature and humidity of the treated air, but the air-conditioning box is only a temperature and has no requirements on humidity.

Air handing unit is a kind of terminal equipment, which can affect the air outlet speed and noise level of air conditioner. Therefore, its selection is very important. Most modern houses and commercial occasions have an inch of land and an inch of gold, and the size of machine room is often compressed very small. Therefore, the design of air-conditioning box is required to fully consider the space limitation on the premise of satisfying functions. At the same time, due to the dense population in these occasions, the requirements for the comfort of the building environment are relatively high. Although the machine room is usually arranged in the area with few personnel, the equipment operation will still bring a lot of noise, so the noise requirements of the unit should be controlled in a low range. For the occasions with high maintenance frequency, the unit is required to be easy to repair and clean. The above is some sharing about the air-conditioning box. If you have different opinions, you can leave a message for discussion.
