Description
Technical field
The present invention relates to a kind of precision air conditioner.
Background technology
According to environment temperature, the humidity standard in when start regulation machine room in the specification requirement of State Standard of the People's Republic of China GB50174-2008 " electronic information machine room design specification " appendix A electronic information machine room at different levels; Wherein environment temperature is: 23 ± 1 ℃ of A level, B levels, 18～28 ℃ of C levels; Ambient humidity is: A level, B level 40%～55%, C level 35%～75%; Environment temperature, humidity standard during shutdown in the machine room, wherein environment temperature is: A level, B level, C level are 5～35 ℃; Ambient humidity is: A level, B level 40%～70%, C level 20%～80%; TIA-942 standard " data center's infrastructure of telecommunication standard " points out that air-conditioning system must guarantee to provide 24 hours every days, annual 365 days, and air-conditioning system must be connected to the stand-by generator system.Way commonly used at present is: civil power just often; Precision air conditioner is regulated the humiture environment in the machine room; During the city electrical anomaly, equipment such as the server in the machine room, router are by the power supply of UPS uninterrupted power source, start diesel-driven generator simultaneously and drive precision air conditioner and regulate machine room humiture environment.Adopt diesel-driven generator to drive precision air conditioner and have shortcomings such as cost is high, power consumption is high, it is big to pollute, environmental requirement height, this does not meet the requirement of the comprehensive programme of work of State Council's issue " 12 " energy-saving and emission-reduction fully.Extensive use along with virtual, cloud computing, blade server etc.; Cause the single rack power consumption of machine room to improve constantly, the unit are heat sharply rises, and traditional refrigeration modes and air-flow enterprise schema can't satisfy the demand of high refrigerating capacity; Solution commonly used at present is: refrigeration unit is placed on the server cabinet next door; Seal the cold air duct of rack simultaneously, avoid the hot and cold air in the machine room to mix, cause problems such as hot-air recirculation, hot localised points.Adopt this mode can effectively solve the high heat density problem of machine room, but in the city during electrical anomaly, high heat density equipment such as blade server is guaranteed its normal operation by the UPS uninterrupted power source; And precision air conditioner can not be supplied power by UPS owing to reasons such as starting current are excessive, at this moment, because the cold air duct of rack is in the complete closed state; Temperature can't be distributed through the natural air convection current in the rack, thereby causes the interior temperature of rack sharply to rise, and is before precision air conditioner is supplied power starting diesel-driven generator; The key equipment machine of having delayed in the rack; Therefore, it is a kind of in the city during electrical anomaly to be badly in need of exploitation, can be as the UPS uninterrupted power source; The uninterrupted precision air conditioner of refrigeration is provided rapidly, ensures that the machine room key equipment also can normally move during electrical anomaly in the city.According to the data that weather bureau provides, Chinese most of areas has 3 months monthly mean temperatures at least below 10 degrees centigrade every year, and the computer room temperature standard is 23 ± 1 ℃; The temperature difference is bigger; Therefore, when this temperature range, can utilize extraneous natural cooling source to regulate the building environment temperature fully.
Summary of the invention
