2방식 응축을 이용한 건조 장치 개발 연구

A heat pump, in the common thermodynamic sense, is a system in which refrigeration components (compressors, condensers, evaporators, and expansion devices) are used in such a manner as to take heat from a source (air, water, ground, etc.) and give it up to a heat sink (air, water, ground, etc.) that is at a higher temperature than the source. For many applications, the heat pump is designed in such a manner as to reverse the cooling and heating functions. With the value of energy today, the heat pump has become a more timely concept. The heat pump dryer has more merits than using hot wind, the sun for drying. First, relatively low electrical rates were necessary for the heat pump to compete favorably in terms of operating costs with fossil fuel fired furances. Second, the heat pump had to have satisfactory reliability and low maintenance requirement. Third, it gives a little environmental impacts. The results of this study are presented fundmental principles of heat pump, reliability of heat pump dryer.
