Description

A kind of compound refrigerated dehumidification method and refrigerated dehumidification hybrid system
Technical field
The present invention relates to data center's field of air conditioning, more particularly to a kind of compound refrigerated dehumidification method and refrigeration Dehumidify hybrid system.
Background technology
With next generation computer integration density more and more higher, processor speed is more and more faster, and its caloric value is also anxious Increase severely length, this high-density installation to rack server and how to radiate and proposes severe challenge.Meanwhile, state People's economy is developed rapidly, Energy situation very severe, and people gradually recognize to save the importance of the energy, And data center, as energy consumption rich and influential family, wherein air conditioning energy consumption accounts for very big ratio again.Available data central machine room is empty Tune mainly has direct expansion DX systems and the major class of chilled water CW systems two.Requirement and server with energy-conservation The rise of heat density, constantly close to server apparatus in itself, Terminal device is also from traditional room-level for refrigeration end Air-conditioning, develop into row between, passage furred ceiling, server cabinet front door, even directly by cold drawing to heat radiation chip Cooled down.Although refrigeration end distance service device is more near more saves, the leakage of refrigeration end water and generation condensation The harm of water is also bigger.There is the potential safety hazard that water enters computer room and server for chilled water CW systems, and Chilled water temperature is relatively low, can produce condensation in heat exchanger surface.Although and direct expansion DX systems inside is without cold Freeze water, but heat exchanger surface temperature needs to be tightly controlled to be allowed to realize dry and cold heat exchange higher than air dew point temperature (freezing without condensation), otherwise also will produce condensed water in heat exchanger surface.
However, DX systems need to be dehumidified while the dry and cold heat exchange in end is realized when computer room humidity is too high When, end heat exchanger can not produce condensation to dehumidify, and influence server reliability service.Existing design In, the precise machine room air conditioner or industrial Special dehumidifier for additionally arranging in pairs or groups common are generally required, engineering is not only caused The increase of amount, reduces computer room effective area, simultaneously because the communication between distinct device can not fully achieve linkage, Also it is unfavorable for the overall temperature and humidity of data center module accurately to control.Meanwhile, traditional DX air-conditioning systems are in computer room Can be by turning down compressor rotary speed or returning a high-temperature gas bypass part for compressor air-discharging side during high humility To evaporator, the temperature of cooling medium in refrigeration end is set to be more than air dew point temperature, this control mode will be led The cooling capacity of whole cooling system is caused to decline, it is difficult to meet the radiating requirements of server apparatus, cause server Excess temperature is even delayed machine.
