Inlet and outlet temperatures of evaporator, condenser, expansion valve and compressor were measured for both air and refrigerant sides. Electric power consumption of compressors, defrosting heaters, cooling water pumps and etc. were measured. The operating characteristics of the showcase system under various working conditions were analyzed and discussed. During the defrosting process, the air temperature inside the showcase increased to 15℃, which gave harmful effect to the frozen food. The collected data will serve as valuable information for diagnosing and improving the performance of showcases. 대한설비공학회 쇼케이스의 현장 데이터 측정 및 분석 Measurement and Analysis of Showcase Field Data Article 2 설비공학 논문집, v.17, no.5, pp.436 - 443 설비공학 논문집 17 5 436 443 kci ART000956988 Supply air temperature Return air temperature Expansion valve Evaporator Condenser Defrost 공급 공기온도 회수 공기온도 팽창밸브 증발기 응축기 제상
