HFC-134a를 적용한 냉온정수기의 실험적 연구

초록

This paper focuses on the performance and characteristics pf HFC-134a as a substitute for CFC-12 in cool & heat purifier. Also this paper deals with design considerations for pressure rise problem of HFC-134a using cylce simulation program. The effects of the charge amount of refrigerant, the length of condenser and capillary tube at the energy consumption test are analyzed. As the results of this study, we found that refrigerant charge is usually 87% as compared to CFC-12, these effects of condenser and capillary tube length are vry important.
