Summary

THE DEVELOPMENT OF SMALL REFRIGERATING UNITS HAS BEEN BASED ESSENTIALLY ON NEW FUNCTIONAL REQUIREMENTS, THE LEVEL OF PRODUCT APPLICATION AND MANUFACTURING ECONOMY, WITH ENERGY SAVING BEING THE MOST IMPORTANT FACTOR. ALTHOUGH NO RADICAL CHANGES HAVE BEEN MADE IN COMPRESSOR DESIGN AND CIRCUITRY, ATTENTION IS BEING GIVEN TO WORKING FLUIDS FOR HIGH TEMPERATURE HEAT PUMPS AND TO NON AZEOTROPIC REFRIGERANT MIXTURES IN ORDER TO ACHIEVE LOW EVAPORATING TEMPERATURES FOR SINGLE STAGE COMPRESSION SYSTEMS WITH REASONABLE COMPRESSION RATIOS. BESIDES THE DEVELOPMENT OF POROUS SURFACE HEAT EXCHANGERS, A COMPUTER PROGRAMME IS BEING USED TO FIND WAYS OF IMPROVING HEAT AND MASS TRANSFER COEFFICIENTS AND EXCHANGER DESIGN PROCEDURES. SPECIAL EMPHASIS IS BEING PLACED ON HEAT PUMP DEVELOPMENT.
