Description
Technical field:
The utility model relates to a kind of air-conditioning system, relate in particular to a kind of pair of low-temperature receiver air-conditioning system, this air-conditioning system is that low-temperature receiver comes the cooling of machine room intercom set according to water temperature in the water tower of mansion roof and moving the selection with the running water in air or the water tower of SEA LEVEL VARIATION order, thereby reaches energy-conservation purpose.
Background technology:
Now the telecom operation commercial city recognizes that the air-conditioning power consumption in its machine room is very big, so studied various machine room air-conditioning energy-saving technology, the machine room air-conditioning energy-saving technical scheme generally used at present is to utilize the outer cold air of machine room to come the nature cooling is carried out in machine room inside.There is the restriction of two aspects in this technical scheme, and first aspect restriction is that cold air enters machine room also bring dust and moisture easily into when bringing cold air into, and dust and moisture are easy to damage the communication equipment in the machine room; Second aspect restriction is that cold air is subjected to Changes in weather to influence instability, and many times its temperature is higher and can not be used for machine room inside is cooled off.
Analyzing communication machine room distributing position statistical information can find that most of machine room all is positioned at the roof of mansion, and the roof of mansion has often been installed the water tower that is used for storing running water.Water in these water towers is followed outdoor cold air in cold day be about the same cold.And the water in the water tower can be held leading water and reduces along with mansion resident family, and supply-water pump again can the standpipe supplementing water then, and like this just as the cold air that flows, the water in the water tower also can replenish the mode of replenishing again constantly " flowing " that releases again to release.If hot day, can cool off the condenser of the common freon air-conditioning in the machine room as low-temperature receiver, thereby the coefficient of refrigerating performance COP that can improve air-conditioning like this reaches certain energy-saving efficiency with the running water in the water tower.And the temperature of the running water in the most of local water tower of China in the most of the time of cold day is lower than 18 degree, the fan coil that can directly deliver to the running water in the water tower in the machine room this time carries out heat exchange, at this moment can stop the freon operation of air conditioner, reach higher energy-saving efficiency.Water in the water tower flows back to water tower again after carrying out heat exchange, also do not waste running water like this in energy-conservation.
Summary of the invention:
In view of this, the purpose of this utility model provides a kind of pair of low-temperature receiver air-conditioning system, this air-conditioning system is that low-temperature receiver comes the cooling of machine room intercom set according to water temperature in the water tower of mansion roof and automatic the selection with the running water in air or the water tower of SEA LEVEL VARIATION, thereby reaches energy-conservation purpose.
