The fan coil assisting radiant floor heating (FCRFH) system can solve the problem of long preheating time of radiant floor heating and make the room soon meet thermal comfort requirements. In order to study the thermal characteristics and thermal comfort of FCRFH system, an experimental system was developed. A series of parameters, such as indoor air temperature, surface temperatures of floor and walls, were measured in the practical operation. Thermal characteristics of starting stage, stable running condition and following the closure were analyzed. Experimental results showed that the FCRFH system had fine thermal comfort, and the indoor air temperature distribution was uniform in both horizontal and vertical directions. Compared with separate radiant floor heating, it was able to meet the thermal comfort requirement after the FCRFH system running for 1 h, which shortened the preheating time more than once.

Key words: Radiant floor, fan coil, assisting heating, preheating time.
