Capillary radiant heating system meets the “reduction efficiency” and takes advantage of low-grade energy principle. In this paper, Experimental Research on office building solar capillary heating system was measured with Indoor and outdoor temperature, wall temperature, capillary inlet and outlet water temperature, and etc. from 8:30am to 18:30pm in Beijing. Capillary heating system dynamic performance and the impact on the indoor temperature and the amount of radiation each wall were analyzed. Experimental results show that capillary heat dissipating capacity is larger than the required heat load (55W/m2) in the room, and the average heat capacity of capillary is 79.6 W/m2 at 10:20-18:30. It is more uniform temperature distribution in the room and the radiation intensity is stronger with the east wall and the Western Wall in the test room. The mean radiant temperature and indoor air temperature is proportional to the change of the negative relationship, and the average radiation temperature and the maximum air temperature difference is 2.4 °C. The result can provide an energy-saving operation assessment method to support Capillary radiant heating system control and optimal heating design in office building.
