버블젯 루프 히트파이프를 이용한 증발기 제상에 관한 연구

Abstract

One of the problems in a refrigerator operation is the frost formation on a cold surface of the heat exchanger. The frost layer is formed when the water vapor meet cold fin & tube which lower than freezing point. This frost layer is usually formed in evaporators and the frost layer on the surface of a heat exchanger will make side effect such as thermal resistance, air volume, fan motor performance and so on. However, This important factor needs to be studied and improved. This study shows a comparison between conventional electric heater and Bubble Jet Loop Heat Pipe as a defrost device in evaporator. They are compared in 4 factors of Evaporator temperature, Air temperature in the chamber, Heater temperature, Electricity consumption. The evaporator applied Bubble Jet Loop Heat Pipe shows low temperature variations in evaporator and air temperature in the chamber and low electricity consumption.
