Reason ability also gradually increases, but the power consumption of equipment also increases therewith, causes the caloric value of equipment within machine cabinet more.According to system
Meter, equipment cabinet server caloric value is big in domestic large-scale IDC computer rooms at present, and essentially annual 8760h operations, new for not using
For the computer room of wind, whole year is both needed to cooling, causes air conditioning energy consumption huge, and its air conditioning energy consumption accounts for data center module entirety energy consumption
40%~50%.
Traditional data computer room air supply mode has the air-supply of bottom plate air channel, the air-supply of cold and hot channel separation and full room refrigeration air-supply etc.
Mode, the pattern have been unsatisfactory for modernizing the refrigeration demand of computer room high density rack, occur that hot-spot, power consumption is big, machine
The problems such as room air conditioning energy consumption is too high, noise is big.Precise machine room air conditioner need to humidify repeatedly simultaneously, dehumidify operating or supporting special dehumidifying
Machine carries out computer room air humidity, dew point control, to ensure that condensation does not occur for device interior, causes computer-room air conditioning system refrigerating efficiency
