Summary

EXPERIMENTS HAVE BEEN CARRIED OUT ON AN EARTH HEAT PUMP UNDER LABORATORY CONDITIONS, USING R22 MIXED WITH VARYING PROPORTIONS OF R114. THE REPORT DISCUSSES THE EFFECT OF DIFFERENT PARAMETERS SUCH AS THE SIZE OF THE HEAT EXCHANGER, CONDENSING AND EVAPORATING TEMPERATURES, AND THE FLOW RATES OF REFRIGERANT AND HEAT SINK FLUIDS. THE RESULTS INDICATE THAT MIXING OF REFRIGERANTS DOES NOT PRODUCE ANY SIGNIFICANT IMPROVEMENT UNDER THE OPERATING CONDITIONS ENCOUNTERED IN SMALL EARTH HEAT PUMP SYSTEMS. THE GENUINELY INTERESTING APPLICATIONS WOULD SEEM TO BE IN LARGE HEAT PUMPS (DISTRICT HEATING SYSTEMS, IN HOT WATER HEATING PLANTS AND FOR INDUSTRIAL PURPOSES).
