Weak current College】 【machine room exclusively used air conditioner and the difference between ordinary comfort air conditioning.

Computer room temperature, humidity and cleanliness have more stringent requirements, therefore, the computer room air conditioner in design and traditional comfort air conditioning has a very big difference, expressed in the following five aspects:
1. traditional comfort air conditioning is aimed at professionals design, air, air enthalpy difference, cooling and dehumidification simultaneously; while the engine out of the total calorie calories 90 percent, it includes the device itself heating, lighting, heating value, through walls, ceilings, Windows, floors, and sunshine import thermal radiant heat, wind through the cracks of permeability and outdoor air heat, etc. The calorific value of moisture is very small, so with comfort air conditioning will result in the engine room the relative humidity is too low, and make the device internal circuit components, static surface accumulation, discharge damage equipment, interference data transmission and storage. At the same time, the cooling capacity of (40% ~ 60%) consumed in dehumidify, making the actual cooling equipment cooling capacity reduction of numerous, considerably increased energy consumption. Machine room exclusively used air conditioner is designed with strict control of the evaporator evaporation pressure, increasing air enables the evaporator surface air temperature above the dew point temperature and moisture, the resulting cold all used to cool down, improve work efficiency, reduces the loss of moisture, which is due to the air, air enthalpy decreases.
2. small comfort air conditioning air, wind speed, direction only in the air, local air circulation in the formation of the whole computer room air circulation, uneven cooling machine room, making the room temperature, in the regional direction of regional air temperature is low, other regional temperature, fever equipment due to a substantial difference in the local thermal accumulation, cause the device to excessive heat damage. The machine room exclusively used air conditioner air, room ventilation times higher (usually in the 30 ~ 60/hour), the whole room can form a whole stream of air circulation, make room for all devices are able to average cooling.
3. the traditional comfort of air-conditioning, ventilation air is small, the fewer the engine air cannot ensure a sufficiently high velocity will dust back to filters, in-room devices internally generated sedimentary, negative effects on the device itself. And General comfort air conditioning unit of filtration performance is poor and does not meet the requirements of your computer. Used machine room exclusively used air conditioner air, air circulation, at the same time due to have a dedicated air filters, timely and efficient filtered out of the dust in the air, just maintain the cleanliness of the room.
4. for the majority of the engine's electronics are continuous running, long working hours and therefore require machine room exclusively used air conditioner is designed to load all the continuous operation, and to maintain the very highest level of reliability. Comfort air conditioning more difficult to meet the requirements, especially in winter, computer room because of its good sealing and heating equipment and much still needs to work normal refrigeration and air conditioning unit, at this point, the General comfort air conditioning due excessively low outdoor condensing pressure is already very difficult to work correctly, machine room exclusively used air conditioner through controlled outdoor condenser, still functioning guarantee refrigeration cycle.
5. machine room exclusively used air conditioner General is also equipped with a private humidification system, efficient dehumidification system and electric heating compensation system, microprocessor, depending on the sensor back data to fankui precise control of room temperature and humidity, and comfort air conditioning generally do not equipped with humidification system, you can only control the precision of temperature and humidity is lower, is more difficult to control, not meeting room equipment needs.
To sum up, the machine room exclusively used air conditioner and comfort air conditioning in product design, significant differences exist, for a different purpose and cannot be used interchangeably. Computer room you must use the machine room exclusively used air conditioner. At present, the domestic many industries such as banking, telecommunications, television stations, petroleum exploration, printing, scientific research, electric power has been widely adopted, increasing the engine room computer, network, communication system reliability and economical operation.
