Description

A kind of air-conditioning method that is applicable to communication base station
Technical field
The present invention relates to a kind of power-saving technology, refrigeration machine method in refrigerator system and Machine Room in espespecially a kind of Machine Room that can be applicable to communication base station.
Background technology
Communication base station energy consumption is huge, accounts for operator's energy consumption more than 70%. In Machine Room, refrigerator system power consumption accounts for the more than 35% of communication base station power consumption, is main dissipative system.
Communication base station mainly comprises refrigerator system in communication equipment, batteries and Machine Room.
Battery requires harsher to environment temperature, require environment temperature not higher than 25 DEG C, therefore existing batteries is to be all placed in " storage battery constant temperature cabinet " that is accompanied with specially refrigeration machine in Machine Room, virtually, has increased again a trouble point.
The environment temperature of communication equipment can be raised to 30 DEG C even higher above. At present, communication base station is in order to meet the requirement of battery to environment temperature, and environment temperature remains on the not level higher than 25 DEG C. In Machine Room, refrigerator system mainly adopts the indoor refrigeration machine machine of separate mechanical, relies on refrigeration machine mechanism cold in Machine Room completely.
Communication base station sealing is very good, the annual heating of communication equipment, and in the time that outdoor temperature is lower, indoor refrigeration duty is still larger, needs refrigeration. In current Machine Room, refrigerator system relies on refrigeration machine mechanism cold in Machine Room completely, can not utilize outdoor natural cooling source refrigeration, and energy consumption is larger. Indoor environment remains on the not level higher than 25 DEG C and has also increased refrigerator system energy consumption in Machine Room in order to meet the needs of battery. In addition, in Machine Room, refrigeration machine machine adopts refrigeration machine machine in normal domestic use Machine Room, removes humidity load larger; And in traditional Machine Room, refrigeration machine adopts the indoor refrigeration machine start and stop of refrigeration machine return air temperature control machinery in Machine Room, in order to make return air temperature can reflect indoor temperature, in Machine Room, the blower fan of refrigeration machine indoor set can not stop forever, and these have all increased energy consumption greatly.
Summary of the invention
Main purpose of the present invention is to provide refrigerator system in a kind of Machine Room that is applicable to communication base station, and it can utilize outdoor natural cooling source, obvious energy conservation to greatest extent.
For achieving the above object, the present invention takes following design:
Be applicable to an air-conditioning system for communication base station, at least include mechanical refrigeration system, heat pipe heat exchanging system and control system; Also comprise a battery vent cabinet, the batteries of communication base station is placed in to this battery vent cabinet, at the arrival end of battery vent cabinet, heat pipe indoor set, refrigeration indoor set and indoor fan are installed successively; In battery vent cabinet, install the first temperature sensor of measuring batteries environment temperature; Around communication apparatus, install the second temperature sensor of measuring its environment temperature; Install the three-temperature sensor of measuring outdoor environment temperature outward at communication base station, each sensor accesses the signal input part of described control system.

In the described air-conditioning method that is applicable to communication base station, before determining according to indoor/outdoor temperature-difference whether heat pipe heat exchanging system preferentially moves, first judgement: measure the environment temperature upper limit whether near the environment temperature of communication equipment is greater than communication equipment requirement, or whether near the environment temperature of battery is greater than the environment temperature upper limit of battery requirement, if not, cycle detection battery environment temperature, communication equipment environment temperature and communication base station outdoor temperature; In this way, continue lower step.
In the described air-conditioning method that is applicable to communication base station, described indoor/outdoor temperature-difference refers to the difference of communication equipment environment temperature and outdoor temperature.
Advantage of the present invention is:
With battery vent cabinet replace storage battery constant temperature cabinet can direct balanced base station in temperature; Battery vent cabinet cost is low, easy for installation, does not hinder storage battery maintenance, maintenance, does not affect battery hydrogen and gets rid of; There is no refrigeration machine in storage battery constant temperature cabinet Machine Room, reduced trouble point, increased the security of total system operation;
2. heat pipe indoor set and the use of connect of refrigeration indoor set, can give full play to the effect of heat pipe heat exchanging system, can utilize to greatest extent outdoor natural cooling source, and use mechanical refrigeration system, as the afterbody guarantee of indoor environment, guarantees that indoor environment temperature is up to standard;
3. due to the setting of battery vent cabinet, make the air-out of indoor set first pass through battery, then pass through communication equipment. The caloric value of battery is little, thereby the air-out of indoor set arrives communication equipment region after battery, still can meet the cooling needs of communication equipment. The environment temperature that battery requires, lower than communication equipment, in the present invention, because first indoor set air-out enters battery region, thereby requires as long as the leaving air temp of indoor set can meet the environment temperature of battery. In prior art, require the return air temperature of indoor set can meet the environmental requirement of battery. Thereby compared with prior art, indoor set evaporating temperature of the present invention can increase substantially (improving more than 5 DEG C), not only extend the heat pipe heat exchanging system whole year operation time, increase the utilization rate of outdoor natural cooling source, and in the time that mechanical refrigeration system moves, also can improve energy efficiency.
4. indoor fan adopts Wind Volume blower fan, not only can improve refrigeration machine evaporating temperature in Machine Room, and can reduce the moisture removal of refrigeration machine in Machine Room, reduces refrigerator operation energy consumption in Machine Room, reduces the energy consumption of overall operation.
5. by judging the start and stop of controlling mechanical indoor refrigeration machine or heat pipe heat exchanging system under certain condition, not only guarantee that facility environment temperature is suitable, and in the time that temperature meets the demands, can cut off indoor fan, save blower fan electricity consumption, having avoided refrigerator system in traditional Machine Room is to make return air temperature can reflect the drawback that indoor temperature causes indoor fan forever can not stop.
