냉각제습장치의 응축기 전열면적 결정을 위한 실험적 연구

Abstract

The temperature and humidity which have been developed in Korea summer causes the dew condensation which results in pollution of structure, mould growth, and electronic short. We can use a dehumidifying to solve the problem. The design of heat exchange area which is about the evaporator and condenser of home appliances including air conditioner consist of the rule from manufacture experiences. Also, dehumidification equipment doesn't have design standards like a home appliances. Therefore the heat exchange area of a condenser is designed more 20~30% than the heat exchange area of an evaporator like air conditioner normally. However I think that air handling process of dehumidification is different from air conditioner. Hence, it is possible to make a compact design to reduce heat exchange area in a condenser. This paper deals with the decision for heat exchange area in condenser to make optimal system when evaporator also is operated ordinarily. As the experimental results, it was found out that the surface temperatures of the evaporator and the condenser can be kept similar each other. Also, as the result of comparing power consumption with the difference of enthalpy, the similar result was deducted in the forth and third sequences of the condenser. It can be possibly planned that the radiator surface is considerably small in the case of a condenser installed in the inside of an air dryer than general refrigeration cycle. This is because heat exchange occurs in the low-temperature air which is flown through the air dryer.
