Cooling performance of a new radiant terminal with water temperature control strategy

Puts forward a new radiant terminal and an anti-condensation control strategy based on hybrid water temperature control and establishes an experimental system. Tests the indoor air temperature, indoor air humidity, surface temperature of building envelope, mixed water temperature, supply and return water temperature and water flow rate. Researches the thermal comfort of the radiant terminal in cooling mode and the feasibility of the control strategy. The results show that the radiant terminal can meet the requirements of ISO 7730 on vertical air temperature difference, radiant asymmetry and floor temperature and the control strategy is feasible. But the control accuracy of mixed water temperature needs to be improved.
