随着“四化”建设的进展,计算机之应用日趋广泛。据统计,用于计算机房空调之能量约占整个计算机房能耗的一半。干冷计算机专用空调机组主要特点是节能。常规空调机组,先将空气冷却到露点(湿冷),将水份析出,然后再加热,冷热抵消浪费能量。干冷空调机组,只将空气冷却到要求温度,不需冷却到露点,不析湿不加热不存在冷热抵消,与常规机组比,约节省40％能量。
With the progress of “four modernizations” construction, the application of computers is becoming more and more widespread. According to statistics, the energy used for computer room air conditioning accounts for about half of the entire computer room energy consumption. Dry and cold computer-specific air-conditioning unit is the main feature of energy-saving. Conventional air conditioning units, first air cooled to the dew point (wet and cold), the water precipitation, and then heating, hot and cold offset energy waste. Dry and cold air conditioning units, only the air cooled to the required temperature, without cooling to the dew point, no wetting does not heat the absence of hot and cold offset, compared with conventional units, saving about 40% energy.
