고밀도 열교환기를 이용한 $NH_3$ 냉동장치의 성능 특성 연구
The Study on Performance Characteristics of NH3 Refrigeration System Using Optimum Heat Exchanger
초록
Nowadays CFCs and HCFCs refrigerants are restricted because it cause depletion of ozone layer. Accordingly, this experiment apply the ammonia gas and not CFCs and HCFCs for refrigerant to study the performance characteristic from the superheat control and improve the energy efficiency from the high performance. The condensing pressure of refrigeration system is increased from 15.0bar to 16bar by 0.5bar and superheat temperature is increased from
