Abstract

In order to improve the cooling capacity of radiant cooling plate and the performance of the plate surface condensation,different water temperature, tube velocity and indoor relative humidity conditions were used as experimental study variables with the method of visual research on the established radiant cooling condensation system and the test platform of the change of thermal performance. The results showed that when the water flow rate increases from 40 L/h to 120 L/h,the cooling capacity increased nearly doubled and condensation time was reduced by 15 min; The indoor temperature and humidity was 26℃,75%,the first condensation time was 8 min;the cooling capacity of copper plate was stronger compared with PPR capillary tube radiation model;The state of dew condensation on the surface of the radiation plate was more disorganized with lower water temperature and amount of condensation.When the indoor temperature and humidity was 26℃,60%,the maximum size of water drops the length was 9.6 mm,the width was 8.8 mm on the surface of the radiant panel.
