Abstract: Because of the influence of the earth’s greenhouse effect, the summer outdoor temperature rising leads to air conditioning in the summer often appear such problems as high voltage protection and the working current is larger,both cause increase of energy consumption,and the safe hidden trouble of equipment operation. In order to reduce the central air conditioning in the summer running cost and safe operation. Building using air conditioning by adding the(soft) on the wind outdoor condenser water spray cooling principle of processing, can not only improve the refrigeration efficiency and reduce the operation cost and equipment safety hidden trouble.

Key words: air cooled central air conditioning, water mist cooling device, energy saving reconstruction
