Evaporating heat transfer characteristics of R-22 in small diameter tubes
세관 내 R-22 의 증발 전열 특성에 관한 연구
Abstract
Evaporating heat transfer characteristics of R-22 were measured inside smooth horizontal copper tubes with inner diameters of 3.36 mm and 5.35 mm respectively. The experiments were conducted in the closed loop which was driven by a magnetic gear pump. Experiments were performed for the following range of variables ; mass velocity of refrigerants (200 to 400
