Title:
METHOD FOR COOLING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2011/070807
Kind Code:
A1
Abstract:
Water treated with a reverse osmosis membrane device (12) is introduced into a circulation line (23) and sprinkled from spray nozzles (14) onto outdoor units (heat exchangers) (15a to 15d). Since the treated water contains none of Ca, Mg, and Cl ions and the like, scale deposition does not occur on the heat exchangers (15a to 15d) and a high cooling effect can be maintained.
