Description of the Related Art As a floor heating device for circulating hot water to a floor heating panel conventionally used, a hot water pipe led from a heat source device serving as a gas combustion device is piped to a floor heating panel laid in a room, and the hot water is circulated. The on-off valve provided on the pipe is opened and closed according to the room temperature to control the bed temperature. In this case, in the floor heating control, the hot water is simply stopped when the room temperature becomes higher than the set value, and the hot water is sent when the room temperature becomes lower than the set value.

熱交換器３によって熱源装置が構成される。FIG. 1 shows a floor heating device for supplying hot water by an on-off valve. Reference numeral 1 denotes a combustion device in which a gas combustion section 2 is disposed below. A pipe heat exchanger 3 wound around the outer periphery of the combustion device 1 is shown. The hot-water pipe 4 connected to the hot water pipe 4 is guided to the floor heating panel 5, and an on-off valve 6 composed of an electromagnetic valve and a circulation pump P are provided in the middle of the hot-water pipe 4. The room temperature sensor 7 to be disposed and the gas valve 8 of the gas combustion unit 2 are connected to the control device 9 to form a floor heating device as a whole. Further, a heat source device is configured by the combustion device 1, the gas combustion unit 2, and the pipe-shaped heat exchanger 3.

が大きく変動しないようにしてある。Next, the operation will be described. First, the hot water heat exchanged by the pipe-shaped heat exchanger 3 by the combustion heating of the combustion device 1 flows into the floor heating panel 5 through the hot water pipe 4 and circulates. The panel 5 is heated, and the room is heated by the radiant heat to increase the room temperature. In this case, the on-off valve 6 is turned on and off intermittently by repeating the on-off cycle, so that the bed temperature does not largely fluctuate as shown in FIG.

t は室温を表す（図４参照）。Here, if the ON / OFF time T (cycle) of the on-off valve 6 is determined in consideration of the set temperature and the room temperature, as shown in Equation 1, the difference between the set temperature and the room temperature can be reduced. it can. In Equation 1, TON is 1
The opening time of the on-off valve 6 in the cycle T, ts is a set temperature,
t represents room temperature (see FIG. 4).

指数関数的に変化させる。Here, as shown in FIG. 3, the open / close ratio of the on-off valve 6 is 50% when the room temperature t coincides with the set temperature ts.
(For example, when one cycle T is 20 minutes, the opening time TON is 10 minutes). When the room temperature t does not coincide with the set temperature ts, the value of the room temperature sensor 7 installed in the room (that is, the room temperature t ) And exponentially according to the deviation between the set temperature ts. That is, when the room temperature t is lower than the set temperature ts, it is necessary to raise the bed temperature. Therefore, the opening / closing ratio of the on-off valve 6 is made larger than 50%.
The opening / closing ratio of the on-off valve 6 is set to 50 to 100 in accordance with the deviation from ts.
% (For example, if one cycle T is 20 minutes, the open time TON
Is exponentially changed within the range of 10 to 20 minutes).
Conversely, when the room temperature t is higher than the set temperature ts, the opening / closing ratio of the on-off valve 6 is made smaller than 50% in order to lower the bed temperature. The opening / closing ratio of the valve 6 is set to 15 to 50% (for example, one cycle T
Is 20 minutes, the opening time TON is changed exponentially within the range of 3 to 10 minutes).
【００１４】その結果、室温t と設定温度tsとの偏差が

つつ快適な床暖房を実現することができる。As a result, the larger the deviation between the room temperature t and the set temperature ts, the more quickly the room temperature t approaches the set temperature ts, and as shown in FIG. Comfortable floor heating is obtained. In addition, no matter how much the room temperature t becomes larger than the set temperature ts, the opening / closing ratio of the on-off valve 6 does not fall below 15%, so that the floor heating panel 5 becomes cold and the feet do not cool down. And comfortable floor heating can be realized.
