The Performance Analysis Study between Evaporator Fan Operating and not Operating at the Air Cooled Refrigerator

This study is that by using gas compression type refrigeration trainer, analysed factor which affect to performance of refrigeration system between evaporator fan operating and not operating condition at the low temperature operating condition of low pressure side. At the evaporator fan operating condition, which is normal heat exchanging situation of refrigerant, analysing study result are high level conditions of condensing pressure, evaporating pressure, flash gas heat, and specially observed too high level of superheat. At the evaporator fan not operating condition, analysing research result are high level of refrigeration effect. coefficient of performance(COP), low level of compression work and wet compression work. By conducting this study, had result that refrigerator operating performance have been big affected by condition between evaporator fan operating and not operating at the air cooled refrigeration system.
