Description
Technical field
The present invention relates to a kind ofly can utilize energy-conservation air-conditioner of outdoor natural cooling source and control method thereof, relate in particular to and be used for air-conditioner and the control method thereof that the machine room room air is handled, belong to the air-conditioner that is used for machine room and the renovation technique of control method thereof.
Background technology
Often have some equipment on the industrial production and need operation throughout the year, and these equipment operations have heat to shed, need the refrigeration duty processing of lowering the temperature the whole year, power consumption is big, is example with the telecom communication base station, because the base station has heat to shed in running, the annual cooling that all needs to carry out air is handled, and cooling means commonly used at present are to lower the temperature by base station air conditioner, and common base station separate air-conditioning is identical with being provided with of room comfortableness split-type air conditioner, indoor set comprises indoor heat exchanger, throttling arrangement; Off-premises station comprises compressor, cross valve and outdoor heat exchanger etc.The power of general compressor of air conditioner is very big, although in the lower situation of outdoor temperature, though efficiency rises to some extent, the electric energy that consumes is quite a lot of, is unfavorable for energy-saving and emission-reduction.
Another kind of cooling method is exactly lower to a certain degree the time than indoor air temperature in outside air temperature, and indoor the outdoor air introduction, the while is discharged to room air outdoor, and the air of outdoor like this lower temperature just can be lowered the temperature to calculator room equipment.The ventilation unit that has adopted at present the outdoor new wind of introduction to lower the temperature all is independently to install with base station air conditioner, and ventilation unit and base station air conditioner are not by same manufacturers produce basically, and collaborative linkage cost that uses between them like this and ventilation unit installation cost have relatively increased much with air processor and the control method cost that the present invention relates to.And indoor equipment often has the requirement of running environment, such as: when humidity increased, the resistance of air reduced, and the probability of the discharge conducting of electrical equipment increases in the equipment, so the humidity in must the control room is in certain scope.Simultaneously, because dust and micronic dust can cause conducting or enter to cause in the element of action and open circuit easily because electrostatic effect is adsorbed on the High-Voltage Electrical Appliances element; Though general ventilation unit all adopts screen pack to come dust in the filtered air, common screen pack can't play a role in filtering to the micronic dust of diameter less than 0.1mm, along with gathering equally of micronic dust can cause the equipment operation troubles.The equipment room ventilation device that adopts is to have no idea to solve similar problem at present, and has limited the application of ventilation unit in this field.
Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of outdoor air of can introducing to lower the temperature, can detect the air-conditioner that is used for machine room of outside humidity and outdoor air concentration of dust simultaneously.The present invention is reasonable in design, and cost is low, and can effectively guarantee indoor cleanliness factor.
Another object of the present invention is to provide a kind of control simple and convenient, the control method of the air-conditioner that is used for machine room that reliability is high.
