Description
Technical field
The invention belongs to communications equipment room falling temperature technique field, especially relate to a kind of wireless communication networks base station machine room hot pipe cooling system and method.
Background technology
Hundreds thousand of of the large common carrier existing communication base station of China three.At present, become the overall situation of fundamental state policy in energy-saving and emission-reduction under, the communications industry, as power consumption big power consumer, is faced with the expense, the problem such as the raising energy, resource utilization etc. that how to reduce capital construction and operation maintenance.
In order to provide a good working environment to communication equipment, to ensure the stable operation of base station, each base station is provided with air-conditioning system, the operation of air-conditioning system needs the electric energy of at substantial, as can be seen from statistics, the power consumption of air-conditioning and base station radio equipment occupies the overwhelming majority of base station total power consumption, and when wherein air-conditioning set temperature is 25 DEG C, air-conditioner power consumption accounts for 42% of total power consumption.Data show, starting with from air-conditioning, to control machine room power consumption be one of energy-conservation key of radio communication base station machine room (hereinafter referred to as base station machine room).
For reducing the power consumption of base station, improve mainly through following two kinds of modes at present: the first, the air-conditioning system being provided with compressor is improved; The second, hot-pipe system is utilized to improve air-conditioning system.Wherein, it is large that first kind of way improves difficulty, and air-conditioning system input cost is high, and power consumption reduces limitation, and result of use is not good.The second way is combined with air-conditioning system by hot-pipe system (i.e. heat pipe air-conditioning system), but although the heat pipe air conditioner system nowadays developed does not use compressor, but generally all need complicated temperature controlling and regulating system is installed, power consumption is energy-conservation unlike traditional air-conditioning system, its disposable output investment ratio is comparatively large, and comprehensive benefit is not high.Simultaneously, above-mentioned hot-pipe system is laid in outdoor usually, its operation principle is: the heat that communication equipment sends imports hot-pipe system into by evaporimeter, working medium (i.e. working media) in heat pipe takes outdoor condenser to by thermal evaporation and by heat, the working medium of gaseous state liquefies within the condenser and rejects heat to outdoor air, and the working medium of post liquefaction gets back to evaporimeter under gravity, so constantly repeatedly, like this because of without installing compressor, then can reach energy-conservation object; But when using in summer or torrid areas, if do not install compressor, above-mentioned heat pipe air conditioner system can not reach the cooling-down effect of expection, main cause is when outdoor temperature is higher, indoor/outdoor temperature-difference is little, and heat pipe air conditioner system does not have compressor, can only heat energy be conducted, thus can not to reach expection.Thus, there is the problems such as equipment investment cost is high, energy-saving effect is poor, cooling-down effect is poor in above-mentioned heat pipe air conditioner system.
In addition, when nowadays setting up temperature regulation system in base station machine room, also there are following mistaken ideas: environmental requirement base station machine room environmental requirement being equal to communication building machine room.In fact the temperature range that in national standard, base station machine room requires is :-5 DEG C ~ 45 DEG C, humidity range 5% ~ 95%.And in GB GB2887-89, specify computer installation site technology condition: environment temperature during start in machine room, humidity standard, wherein environment temperature is: A level 22 DEG C ± 2 DEG C, B level 15 DEG C ~ 30 DEG C, C level 10 DEG C ~ 35 DEG C; Ambient humidity is: A level 45% ~ 65%, B level 40% ~ 70%, C level 30% ~ 80%; The standard of general communications equipment room all should reach A grade standard.The above-mentioned environmental requirement about computer installation place is the environmental requirement of communication building machine room, because base station machine room is long-term unmanned at internal work, and the building machine room that communicates has people for a long time at internal work, that is, the environmental requirement of base station machine room is starkly lower than the environmental requirement of communication building machine room, thus in base station machine room, traditional air-conditioning system be installed and configure the temperature controlling and regulating system of function admirable, too improve the Environmental Technology requirement of base station machine room, cause the very large wasting of resources, in fact be not that the temperature adjustment problem that Conventional air conditioning units could solve base station machine room must be installed.
