ShareEFFECTIVENESS OF FINNED-TUBE HEAT EXCHANGER COATED HYDROPHILIC-TYPE FILM.
Author(s) : MIMAKI M.
Summary
FINNED-TUBE AIR HEAT EXCHANGERS IN HEAT PUMP-TYPE ROOM AIR CONDITIONERS OPERATE AS BOTH EVAPORATORS AND CONDENSERS. WHEN OPERATED AS AN EVAPORATOR, IT PRESENTS THE FOLLOWING PROBLEMS: DRAINING FROM SURFACE OF FINS ATTACHED TO THE INDOOR UNIT DURING COOLING IN SUMMER AND DEFROSTING OF THE OUTDOOR UNIT DURING HEATING IN WINTER. TO OVERCOME THESE PROBLEMS, HYDROPHILICLY COATED FINS WERE TESTED. IT WAS CONFIRMED THAT THEY LED TO A 40-50% REDUCTION OF AIR PRESSURE DROP ACROSS THE HEAT EXCHANGER.
