The difference between the fresh air unit and the air conditioning unit is one: the fresh air unit is used to process fresh air. In a large building, the fresh air unit is generally used in conjunction with the fan coil unit, and the fan coil unit + fresh air fan is actually almost the same as the air conditioner; Under normal circumstances, the air conditioner itself has a fresh air outlet, which is used to ensure the quality of indoor air and supplement indoor exhaust air. Since the fan coil does not have a fresh air outlet, it needs a fresh fan to provide it. The treated fresh air provided by the fresh air unit and the return air processed by the fan coil unit may be mixed first and then processed by the fan coil unit before being sent into the room.
The second difference between the fresh air unit and the air conditioning unit: the fresh air unit mainly processes outdoor air, while the air conditioning unit is used to process the air processed by the fresh fan; but the fresh fan can have return air, and the return air can also have fresh air. The purpose is for better The adjustment of temperature and humidity and other parameters.
The third difference between the fresh air unit and the air conditioning unit: Generally speaking, the fresh air unit does not bear the heat and humidity load of the air-conditioning area, and its main function is to deliver fresh air. Of course, the ideal state is that the temperature and humidity of the supply air are constant, so the fresh air unit generally controls the temperature and humidity of the supply air.
The fourth difference between the fresh air unit and the air conditioning unit: the air conditioning unit loads the heat and humidity load in the air-conditioned area, which has a comprehensive treatment effect on the air in the air-conditioned area, while ensuring a certain amount of fresh air. Air-conditioning units usually mainly control the temperature, humidity and air quality in the air-conditioned area, and the air handling process is generally more complicated.
The difference between fresh air unit and air conditioning unit five: air conditioning units are relatively complicated in terms of air handling. New fan units are relatively complicated in technology, so air conditioning units are mostly used in large-scale public areas where fan coils cannot be installed, while fresh fan units are mostly equipped with fan coils. The use of small space.
The use and installation of air conditioning units and fresh air units are more common. Fresh air units and air conditioning units are different, but they can complement each other in function. It is recommended that you install a new fan unit at the same time, and then install a separate fan coil unit in each room, so that you can learn from each other's strengths, and at the same time achieve the goal of more energy saving and comfort.
