Experimental study of the thermal performance of combined floor and Kang heating terminal based on differentiated thermal demands

Through testing indoor air temperature and surface temperature of the floor and the Kang, and the comparative analysis of energy consumption and radiant temperature asymmetry, a series of results were obtained. The three above-mentioned temperature parameters could not meet the differentiated thermal demands when the floor and Kang heating worked independently and were higher compared to the comfort temperature range excluding the Kang surface in a sleeping state as long as the combined heating performed concurrently. Compared to the above three cases, the alternative operation of the combined heating terminal could efficiently satisfy the differentiated thermal demands. Both the energy consumption and the radiant temperature asymmetry in case 4 were not much high. The obtained test results of the four cases could provide the basis for the combined floor and Kang heating terminal to become an attractive rural heating approach.
