Document Type and Number:
Japanese Patent JP6851256
Kind Code:
B2
Abstract:
To provide a floor heating system capable of improving room temperature adjustment performance to reduce energy consumption.SOLUTION: A cycle time of a floor heating system 2 is set within a range of 30-60 min, and an ON time of a thermal dynamic valve 24 is subjected to duty control, so that hot water is intermittently supplied from a heat source 23 to a floor heating panel 21, wherein the thermal dynamic valve is installed in a circulation circuit 22 connecting the heat source 23 and the floor heating panel 21. Then, when 20 minutes elapse after starting the cycle time, in a case where the temperature deviation obtained by subtracting a setting time from a room temperature is not more than -1.0°C, the cycle time and a duty ratio are reset, and the duty control is started over.SELECTED DRAWING: Figure 3
