Precision air conditioners usually have the following performance characteristics:
Large air volume, small enthalpy difference
Compared with comfort air conditioners with the same cooling capacity, the circulating air volume of precision air conditioners dedicated to computer rooms is about When it is twice as large, the corresponding enthalpy difference is only half. Dehumidification is usually not required when running a dedicated precision air conditioner in the computer room. The larger circulating air volume will make the unit operate above the air point. There is no need to deal with the humidity load like a comfort air conditioner. The air is cooled below the cooling point, so the unit can improve the thermal efficiency of the unit by increasing the evaporation temperature of the refrigerant, thus improving the economical operation. According to experience, the energy consumption per unit cooling capacity of a unit with a sensible heat ratio of . is only about that of a unit with a sensible heat ratio of . Similarly, the computer room requires relatively stable temperature and humidity indicators. A larger circulating air volume will help stabilize the temperature and humidity indicators in the computer room. Obviously, when the cooling capacity is certain, an increase in the air volume will lead to a reduction in the enthalpy difference. Therefore, usually the unit can only It operates under conditions with a very high sensible heat ratio, which is exactly in line with the load characteristics of the computer room. Usually, 3 of the cooling loads of comfort air conditioners are to eliminate latent heat loads, and some are to eliminate sensible heat loads. For the computer room, the situation is quite different. The computer room is mainly composed of the sensible heat emitted by the equipment, the heat load emitted by the indoor staff and the heat and moisture load of the fresh air entering the room in summer (only accounting for the total load). And in winter, humidification is needed instead of dehumidification. Even in winter, the computer room still needs to eliminate the heat load, especially the program-controlled computer room. In view of the above characteristics, if a general comfort air conditioning unit is used in the computer room, it will cause a waste of energy. For example, in a computer room with a heat load of , if a dedicated air conditioning unit for the computer room is used, the total power consumption will be . Air conditioners with the same cooling capacity have different air volumes. The air volume to cooling capacity ratio of comfort air conditioners is:, while the air volume to cooling capacity ratio of constant temperature and humidity air conditioners is:.. Precision air conditioners dedicated to computer rooms have large air volume and small enthalpy difference. , characterized by high sensible heat ratio, usually the enthalpy difference is about 0. In other words, the heat load of the computer room is the sensible heat load. The higher the sensible heat ratio of the same heat load, the greater the air supply volume required. This requires the air conditioning system of the computer room to provide a large air supply volume, so the air supply volume of the general computer room is ~ times larger than the air supply volume required for a general comfort air-conditioned room.
