Summary

THE PERFORMANCE OF AN R22 COMPRESSOR WAS ANALYSED FOR DEHUMIDIFYING HEAT PUMP DUTY WITH R22, R12 AND R11 AS WORKING FLUIDS. OF THE THREE, IT WAS FOUND THAT R12 WAS THE MOST SUITABLE FOR ACHIEVING SIMULTANEOUS HEATING AND DEHUMIDIFICATION OF AIR. EXPERIMENTS WERE CARRIED OUT IN AN OPEN TUNNEL ON A HEAT PUMP USING A COMMERCIAL, HERMETICALLY SEALED, WINDOW AIR CONDITIONER COMPRESSOR CHARGED WITH R12. THE EFFECTS OF AIR TEMPERATURE, AIR FLOW RATE AND EVAPORATING PRESSURE WERE STUDIED. ACTUAL PERFORMANCE FACTORS IN THE RANGE OF 1-4 COULD BE ACHIEVED.
