FLOOR HEATING DEVICE, ITS TEMPERATURE CONTROL METHOD AND ITS CONTROL PROGRAM

PROBLEM TO BE SOLVED: To provide a floor heating device or the like capable of controlling temperature while considering influence by radiation heat from a floor surface or the like, and providing comfort. SOLUTION: This floor heating device S comprises a floor heating panel 20, a panel temperature sensor 30 for measuring a temperature tPof the floor heating panel 20, a room temperature sensor 40 for measuring an indoor air temperature ta, and a control device 50 for conditioning a temperature of a floor surface by controlling a heat generation temperature of the floor heating panel 20. The control device 50 controls an action temperature T0=(tr+ta)/2 determined on the basis of an average radiation temperature trand the indoor air temperature tawithin a comfort range, and comprises an average radiation temperature calculating portion 541 for calculating an average radiation temperature trfrom a temperature of the floor heating panel and the indoor air temperature ta, an action temperature storing portion 552 for storing a comfort action temperature, an action temperature calculating portion 542 for determining the action temperature T0by using the average radiation temperature tr, a temperature control signal generating portion 544 for controlling the heat generation temperature of the floor heating panel 20 in accordance with difference between the action temperature T0and the comfort action temperature, and the like.
