- Abstract
Indoor temperature, cooling capacity and condensation characteristic of capillary tubes for floor cooling were specially investigated with 20℃,18℃,16℃ inlet water temperature. Experiment was carried out in a bedroom in Chongqing in sunny, cloudy and overcast weather condition. The results showed that the highest indoor temperature was 27.6℃, the maximum cooling capacity were 23 W/m2,33 W/m2,32 W/m2 respectively. Adverse condition of condensation was happened between 10:30 to 14:50, among which 80% area started condense from 11:00 to 13:00. Indoor air eddy area was very easy to be condensed. The dehumidifier could reduce condensation dramatically with 18℃ inlet water, but eddy area was still condensed with 16℃ inlet water, The condensation area was related to indoor air distribution, the capillary tubes should be installed avoid air eddy area.
