Abstract
The low-temperature hot-water floor radiant heating system could intermittently work without impacting the indoor thermal comfort conditions for occupants. According to the urban resident life work and rest mode and the change characteristics of indoor air temperature caused by intermittent operation of this system, the control strategies of the system of the urban residential building were proposed. The control strategies contained the average temperature adjustment of coil supply and return water and the time adjustment of system start/stop. In the different control strategies, the indoor air temperatures of the south room and the north room were analyzed by numerical simulation. The results indicated that to meet the thermal comfort requirements for most occupants, the north room needed to be heated about 18 h per day, while the south room only needed to be heated for 13–14 h per day.
