Obiettivo THE THERMAL CAPACITY AND THE COP OF A COMPRESSOR HEAT PUMP CAN BE CONSIDERABLY IMPROVED WHEN INSTEAD OF A PURE FLUID, A FLUID MIXTURE IS USED. CONTRARY TO A PURE FLUID, SUCH A MIXTURE HAS A TEMPERATURE VARIATION DURING THE VAPORIZATION AND CONDENSATION STAGES, WHICH, WHEN PARALLEL TO THE TEMPERATURE CHANGES OF THE FLUID WITH WHICH HEAT EXCHANGE TAKES PLACE, CAN LEAD TO A BETTER HEAT TRANSFER AND TO A HIGHER COP AND/OR THERMAL CAPACITY. THE OBTAINED CAPACITY INCREASE REACHED 28 % FOR WATER-WATER UNITS AND 24 % FOR AIR-WATER UNITS USING A FLUID MIXTURE OF R23 AND R22; THE COP WAS IN THIS CASE ALSO SLIGHTLY IMPROVED. WITH A FLUID MIXTURE OF R12 AND R21 THE COP COULD BE INCREASED BY 10,5 % AS COMPARED TO PURE R21; THE CAPACITY DECREASED SLIGHTLY. A CHOICE WAS MADE FOR THE FURTHER DEVELOPMENT OF HEAT PUMPS WITH R23/R21 MIXTURES WHICH INCREASE THE HEAT CAPACITY. THIS RESULTED IN A COST REDUCTION PER UNIT OF PRODUCED HEAT OF 10 %. ENDURANCE TESTS GAVE VERY GOOD RESULTS AND 20 HEAT PUMPS HAVE BEEN TESTED IN HOUSES DURING THE SEASON 1982/1983. THIS FLUID MIXTURE HEAT PUMP IS NOW BEING COMMERCIALIZED. THIS PROJECT HAS A FOLLOW-UP IN A CEC DEMONSTRATION PROJECT WHERE THE ECONOMIC AND TECHNICAL FEASIBILITY WILL BE DEMONSTRATED.
