碩士 / 國立中央大學 / 能源工程研究所 / 97 / The main purpose of this research is to design a new kind of evaporator/condenser heat exchanger, which is applied to an integrated, one-bed, closed-type adsorption air conditioning system. The micro-fin were manufactured on this heat exchanger to bring the surface tension in order to heat transfer enhanced. This research will test two kinds of different heat exchangers, one is with micro-fins and another is plain-fins. In compare of the experiment results of these two heat exchangers, we found that evaporator/condenser heat exchanger with micro-fin have higher heat transfer performance. This result proved that the surface tension can increase heat transfer.
Besides, this research also experimented on different condense temperature. We found that with the decrease in condense temperature, the heat transfer coefficient would also decrease.
