ABSTRACT. THIS PAPER PRESENTS THE RESULTS OF AN EXPERIMENTAL STUDY ON CONCENTRIC CAPILLARY TUBE-SUCTION LINE HEAT EXCHANGERS COMMONLY USED AS EXPANSION DEVICES IN HOUSEHOLD REFRIGERATORS AND FREEZERS. HEAT EXCHANGER PERFORMANCE WITH THE HYDROFLUORCARBON R-134A WAS EXPERIMENTALLY EVALUATED FOR A RANGE OF HEAT EXCHANGER ASSEMBLIES (INTERNAL DIAMETER AND LENGTH OF THE CAPILLARY TUBE, LENGTH AND RELATIVE POSITION OF THE HEAT EXCHANGER) AND OPERATING CONDITIONS (CONDENSING PRESSURE AND SUBCOOLING). BASED ON THE RESULTING PERFORMANCE DATA BASE, THE INFLUENCE OF BOTH THE OPERATING CONDITIONS AND HEAT EXCHANGER GEOMETRY ON THE REFRIGERANT FLOW AND TEMPERATURE PROFILES WERE EXAMINED.
KEYWORDS: DOMESTIC REFRIGERATION, CAPILLARY TUBE, EXPANSION DEVICE, HEAT EXCHANGER
