A study on frost generation and difrosting mechanism on evaporating tubes for Air-conditioning system

냉동공조용 증발기에서 서리의 발생 및 제상 메커니즘에 관한 연구

In this experiment study, to acquire elementary data for explaining to generate frost layer in the fin - tube evaporator. the experiment condition is to supply air on 0.3m/s, 0.6m/s, 0.9m/s and inlet air temperature is kept constantly $20^{\circ}C$, supplied air relative humidity is 70%, 80, 90%. And brine temperature in the copper tube was kept $-15^{\circ}C$ because, generally cooling temperature range is constantly $-15^{\circ}C$ in the heat exchanger for air conditioning system. in conclusion, through this experiment, we did compare with frost layer and frost quantity in each condition and examine these data
