Abstract
In this research, results of measuring temperature and relative humidity of underground-air-heat in Jeju showed $15{\sim}18^{\circ}C$ and 70~80% each which are somewhat high compare to other regions. So the Multi-effect dehumidifying and heating Heat Pump system which has merged functions of dehumidification and heating is made to solve this problem mentioned previously. When the suction air was $15^{\circ}C$ with 60% humidity, the outcome was 1.70 on $COP_h$ and 1.797(kg/h) on total amount of dehumidification, and also showed 1.87 $COP_h$ with 1.87 total amount of dehumidification under the condition of $20^{\circ}C$ and 80% humidity of suction air. Furthermore, $COP_h$ showed increased number which is 1.87 and also total amount of dehumidification increased which was 3.269(kg/h). The highest COP can be achieved at $17^{\circ}C$ and 70% relative humidity condition.
