Description
Technical field
The invention belongs to field of refrigeration, particularly a kind of computer-room air conditioning system.
Background technology
Along with the high development of the communication technology, the demand setting up machine room for various data center gets more and more.And computer-room air conditioning system is the key of Design of Machine Room, mainly play the heat radiation cooling various equipment, the effect maintaining machine room constant temperature.Computer-room air conditioning system has following features because of its applied environment:
1, refrigeration is continued
Because the caloric value of data center module is very large, some IDC machine room caloric values reach more than 30kw/ ㎡ especially, so energy-saving machine room air-conditioning whole year is all refrigeration.
2, sensible heat ratio is high
Sensible heat ratio is the ratio of aobvious cold and general refrigeration ability.The general refrigeration ability of energy-saving machine room air-conditioning is aobvious cold and latent cold sum, wherein sensible heat refrigeration be used to lower the temperature, and dive cold be used to dehumidify.The heat mainly sensible heat of machine room, so the sensible heat ratio of energy-saving machine room air-conditioning is higher, generally more than 0.9 (common air-conditioning only has about 0.6).Wind Volume, little break difference is the essential distinction of energy-saving machine room air-conditioning and other air-conditionings.Adopt Wind Volume, leaving air temp can be made to be unlikely to too low, and strengthen the rate of ventilation of machine room, this is all favourable to the computing of server and computer.In the short time of machine room variations in temperature too conference cause server operation mistake, the too low meeting of machine room humidity causes electrostatic (humidity electrostatic in 20% can reach 10,000 volts).
3, Energy Efficiency Ratio is high
Ratio between Energy Efficiency Ratio (EER) i.e. ability and institute's consumed power.Energy-saving machine room air-conditioning adopts scroll compressor, and COP is maximum can reach 5.6.The Energy Efficiency Ratio of complete machine reaches more than 3.0.
4, constant temperature and humidity
Energy-saving machine room air-conditioning not only can regulate temperature, also can be able to regulate humidity, and precision is all very high.Data center module particularly server has extra high requirement to temperature and humidity, if change is too large, the calculating of data center module just may go wrong, and is very disadvantageous particularly bank and communications industry to service provider.The temperature accuracy of energy-saving machine room air-conditioning reaches ± and 2 DEG C, humidity precision ± 5%, the temperature accuracy of energy-saving machine room air-conditioning reaches ± 0.5 DEG C, and humidity precision reaches ± and 2%.
The heat dissipation capacity of the server used due to data center or logical credit device itself is more and more large, the requirement of equipment to epidemic disaster can not have been met by traditional air conditioner refrigerating mode, in order to reach the cooling of equipment high efficiency rate, not produce hot-spot phenomenon, cold air must carry out heat extraction by the inside of the access arrangement organized, now adopt the mode of hot and cold channel separation or closed hot and cold passage, effectively can control because of cold wind air-flow and hot-air flow short circuit, and reduce the effect of cooling.Between row, air conditioner in machine room is placed between server cabinet row, near the equipment that thermal source directly dispels the heat, cold wind be from the air-supply of cold passage, after by the horizontal blast mode of passage of heat return air, thus completely solve the problem of hot and cold air short circuit, ensure the even of server cabinet temperature, eliminate hot localised points, and then the operational reliability adding server unnecessary energy consumption is effectively fallen simultaneously.
