The Contrastive Analysis of Several Radiation Cooling Terminal Devices
From three ways of the temperature gradient, the change rate of indoor temperature and heat flux, contrast analysis the cooling effect of three cooling devices on the capillary tube, cooling ceiling and radiant floor, the conclusions could be obtained. The average of vertical temperature gradient in simulated room is equal to 1°C/m, which meets the requirements of human thermal comfort. When the temperature in simulation room falls from 30°C to 26°C, the temperature drop velocity for cooling ceiling is the fastest. The heat flux of the cooling ceiling is maximum, the second one for the capillary tube, and the least one for the radiant floor. Thus, the cooling effect of cooling ceiling is the best.
