An experimental study on the operating performances of the coupled radiation panels with household replacement fresh air system.

Yangtze River region of China have high temperature in summer, and low temperature in winter, with high humidity most of the year. This paper introduced a novel household air conditioning system suits for small-scale buildings in hot-humid climate region, named coupled radiation panels with household replacement fresh air (RP&HRFA) system, which could independently control the temperature and relative humidity of the indoor air. The RP&HRFA system can be operated in five different modes so as to be adaptive to different weather conditions all year round. In this paper, an experimental study under these five operating modes, namely, summer, transitive A, transitive B, winter A, winter B, were carried out. The operating performances of the novel system were investigated under stable experiment operation conditions. The experimental results indicated that the novel system can independently control the indoor air temperature and humidity through effective control methods under various outdoor conditions.
