C-46 Study on Non-Condensing Air-Conditioning System for Next Generation (Part 12) : Study and Comparison of the System at whole Summer period by Simulation

Abstract

The purpose of this study is to realize a non-condensing environment by developing a new type of desiccant air-conditioning system with higher energy efficiency. In this paper, the overall energy efficiency and IAQ of new type of desiccant outdoor air-conditioning systems which are combined with CO_2 heat pump are compared with those of the conventional outdoor air-conditioning systems, by simulated calculation at typical hotel rooms over summer period.The results show that the system COP of the proposed systems is considerably higher than those of the conventional outdoor air-conditioning systems, although non-condensing environment and higher level of IAQ is achieved.
