Computer room on the temperature, humidity and cleanliness are more strict requirements, therefore, computer room in the design of special air conditioning with traditional comfort air conditioning is a big difference. Traditional comfort air conditioning is mainly for personnel to design, send air volume is small, supply air enthalpy difference is large, cooling and dehumidification simultaneously; Sensible heat and the telecom room accounts for over 90% of the total quantity of heat, it includes the device itself fever, lighting calorific value, through the wall, the amount of thermal conductivity of smallpox, window, floor, and the radiant heat from the sun, through the infiltration of aperture wind and air heat, etc. The calorific value of moisture content is very small, so the comfort air conditioning is bound to cause the room relative humidity is too low, and make the circuit components inside the equipment surface accumulation electrostatic, firing in damage to equipment, data transmission and storage. At the same time, due to the capacity ( 40% ~ 60%) Consumption on the dehumidification, the cold makes the actual cooling equipment to reduce a lot, greatly increased the consumption of energy. Rooms adopt strict control on the design of special air conditioning evaporator inside the evaporation pressure, increase air output make evaporator surface temperature is higher than the air dew point temperature and not dehumidification, all the cold quantity used for cooling, improve the working efficiency, reduces the loss of moisture content, namely, because of the large supply air supply air enthalpy difference decreases. Computer room on the temperature, humidity and cleanliness are more strict requirements, therefore, computer room in the design of special air conditioning with traditional comfort air conditioning is a big difference. Little comfort air conditioning wind, wind speed is low, only local air circulation, in the air supply direction cannot be formed in the engine room of the whole air circulation, engine cooling uneven, makes the room within the regional difference in temperature and low temperature air supply direction area, other area temperature, heating equipment due to put the position different local heat accumulation, cause damage to the equipment overheating. And equipment room dedicated air conditioning air output is big, high room air changes ( Usually in 30 ~ 60 times per hour) , whole room can form the overall air circulation, make the all equipment inside the room can get cooling on average. Rooms dedicated air-conditioning, generally also equipped with a special humidification system, high efficiency of dehumidification system and electric heating compensation system, through the microprocessor, according to the data of each sensor feedback back to accurately control the temperature and humidity inside the room, and general don't deserve to proceed wet comfort air conditioning system, can control temperature and low precision, humidity is more difficult to control, can't meet the needs of the engine room equipment. Equipment room dedicated air conditioning and the comfort air conditioning in the difference between product design, the both is designed for different purposes, cannot be used interchangeably. In the computer room must use rooms dedicated air-conditioning.
