Air units mainly deal with the outdoor air, and the air conditioning unit for processing machine processing of air through the air, but the air machine can have air, air can also have fresh air, its purpose is to adjust the temperature and humidity parameters such as better.
Fresh air units generally do not take the heat and humidity load in the air conditioning area. The main function is to send fresh air. Of course, the ideal condition is that the temperature and humidity of the air supply are constant, so the fresh air unit generally controls the temperature and humidity of the air supply.
Fresh air unit is used to deal with new air, in a large building, the general new air unit is used with fan coil units, fan coil units + fresh air machine is in fact almost the same as the air conditioner. Under normal circumstances, the air conditioner itself has a new air outlet, new air used to ensure the quality of indoor air, and to supplement the indoor air exhaust. Because no new fan coil outlet, so the need to provide fresh air blower, air units provide the fresh air through the fan coil and the processed air, or is mixed by fan coil, and then into the room.
The air conditioning unit loads the heat and humidity load in the air conditioning area, which plays a comprehensive role in the air conditioning area and ensures a certain amount of fresh air. The air conditioning unit usually controls the temperature, humidity and air quality in the air conditioning area, and the air handling process is generally complicated.
Whether it is air conditioning units or air units use and installation are more common, different air units and air conditioning units, but complementary functions, we recommend you to install air units at the same time, and each room to install a separate fan coil, so that can do each other, but also can achieve the purpose of saving more comfortable。
Air conditioning unit for a fresh air unit in the process is relatively complex air treatment, so the air conditioning unit used in large scope can not install the fan coil and fresh air unit and many public areas, with the installation of small range space using fan coil.
