열전소자를 이용한 냉동기의 과냉 시스템에 관한 연구

다국어 초록 (Multilingual Abstract)

In this paper, the performance of the Refrigerator is improved by controlling the fan speed on the condenser side or subcooling/superheating degree by superimposing the refrigerant on the inlet side of the compressor to the outlet side pipe. However, these methods may have the effect of lowering the performance due to operation of the severe condition of the main parts and may not achieve the intended performance. The Peltier Module was used to improve the performance of the refrigerator and increase the durability of the main parts through an artificial subcooling device.
