And a control circuit 14 as a control means for controlling the opening / closing of the on-off valve 2 by comparing the value with the value. The temperature setting means 12 is incorporated in a remote controller 15 or the like provided in the room, and outputs the temperature setting value set by the user to the control circuit 14 as a setting signal. The comparison value generating means 13 detects a room temperature detecting sensor 16 for detecting a room temperature, a heat medium temperature detecting sensor 17 for detecting a temperature of a heat medium returning from the floor heating panel 3 to the heat source device 1, and a surface finish. A temperature comparison value is calculated from the type setting value of the surface material setting means 18 that can set the type of the material 6 numerically and output to the control circuit 14 as a comparison signal. The room temperature detection sensor 16 and the surface material setting means 18 are both arranged on the remote controller 15 together with the temperature setting means 12, and the room temperature detection sensor 16 also outputs to the control circuit 14. The heat medium temperature detection sensor 17 is arranged in the return pipe 11.

The control circuit 14 basically compares a temperature comparison value, which is a comparison signal, with a temperature setting value, which is a setting signal, and controls the opening / closing of the on-off valve 2 so that the temperature comparison value becomes the temperature setting value. . In floor heating, Te = Tr + k1 (Tf−Te) between the sensible temperature Te, the room temperature Tr, and the floor surface temperature Tf.
Tr). Here, k1 is a constant determined by the way of living. Further, the floor surface temperature Tf can be directly detected by using an expensive radiant heat sensor or the like, but can be obtained based on the temperature of the heat medium of the return pipe 11 whose behavior related to temperature is stable. That is, Tf = T
The floor surface temperature Tf can be calculated by calculating r−k2 (Tr−Tb). Here, k2 is a constant determined by the type of the surface finish material 6, and Tb is the return pipe 11
Is the temperature of the heat medium.

The comparison value generating means 13 includes Tr by the room temperature detecting sensor 16 and Tb by the heat medium temperature detecting sensor 17.
And k2 by the surface material setting means 18 are respectively input to obtain the floor surface temperature Tf, the above-described calculation is further performed to obtain the sensible temperature Te, and this sensible temperature Te is output to the control circuit 14 as a temperature comparison value. It is a thing. After all, the control circuit 14 controls opening / closing of the on-off valve 2 so that the sensible temperature Te reaches the temperature set value.

Subsequently, according to the flow chart shown in FIG.
The control operation of the control circuit 14 will be described. When the floor heating system is stopped, the on-off valve 2 is closed and the heat medium is not circulating. When the operation is instructed by the remote controller 15, the control circuit 19 of the heat source device 1 starts the operation of the heat source device 1 to heat the heat medium. The comparison value generation means 13 includes a Tr by the room temperature detection sensor 16 and the heat medium temperature detection sensor 1
Tb of 7 and k2 of the surface material setting means 18 are respectively input, the floor surface temperature Tf is calculated, the sensible temperature Te is further calculated, and the sensible temperature Te is output to the control circuit 14 as a comparison signal at constant time intervals. . In step 101, the control circuit 14 compares the temperature set value Ts from the temperature setting means 12 with the sensible temperature Te, and the temperature set value Ts is the sensible temperature Te.
If it is higher than the sensible temperature Te, the process proceeds to step 102, and if it is lower, the process returns to step 101.

In step 102, the opening / closing valve 2 is opened, the heat medium is circulated through the floor heating panel 3, and the process proceeds to step 103. In step 103, the temperature set value T
It is determined whether s is equal to or lower than the sensible temperature Te, and the temperature setting value T
If s is equal to or lower than the sensible temperature Te, the process proceeds to step 104,
Otherwise, return to step 102. Step 104
Then, the process for closing the on-off valve 2 is performed and step 105
Go to.

By the processes up to step 104, the floor heating based on the sensible temperature with the temperature set value Ts as the target temperature is carried out. In step 105, it is determined whether the temperature set value Ts is lower than the room temperature Tr detected by the room temperature detection sensor 16. If the temperature set value Ts is lower than the room temperature Tr, the process proceeds to step 106, and if the temperature set value Ts is higher than the room temperature Tr, the step is performed. Proceed to 107.

In step 106, it is judged whether or not the temperature set value Ts is equal to or higher than the room temperature Tr. If the temperature set value Ts is equal to or higher than the room temperature Tr, the process returns to step 102 and the subsequent processes are repeated. If not, the process returns to step 104. . In step 107, it is determined whether the room temperature Tr is falling. If it is descending, the process returns to step 102, and if not, the process returns to step 104.

Steps 105 and subsequent steps are processing for maintaining the accuracy and stability of the control after closing the valve. That is, the opening / closing valve 2 is closed in the process of step 104, and the floor heating panel 3 is closed.
When the heat medium does not circulate in the heat medium temperature detection sensor 17
Although Tb due to is falling, the heat medium temperature detection sensor 17
There is variation in the drop of Tb due to the difference in the mounting position, and if the sensible temperature Te is controlled as a temperature comparison value with the variation in Tb, the accuracy of temperature adjustment is reduced. Sensor 1
The control is performed using only the room temperature Tr and the temperature set value Ts according to 6. The room temperature Tr may or may not exceed the temperature set value Ts depending on the floor surface temperature Tf before the opening / closing valve 2 is closed. As shown in FIG. 4, if the room temperature Tr exceeds the temperature set value Ts after the opening / closing valve 2 is closed, the opening / closing valve 2 is opened when Ts ≧ Tr in step 106.

On the other hand, as shown in FIG. 5, after the opening / closing valve 2 is closed, if the room temperature Tr starts to decrease without exceeding the temperature set value Ts, the opening / closing valve is started at step 107 at the time of starting the decrease. Open valve 2. In comparison between the temperature set value Ts and the temperature comparison value or the room temperature Tr, a constant differential is provided as in the normal control to provide stability of control. Also, the heat medium temperature detection sensor 1

That is, after the on-off valve 2 is closed, if the open state is not maintained for a long time, the on-off valve 2 is opened for a fixed time, the heat medium is circulated to the floor heating panel 3, and the surface temperature Tf is increased. When the room 5 that is being heated is exposed to solar radiation or is being used in combination with another heater, the opening / closing valve 2 is closed because the room temperature is high due to the sunlight or the heater. Even after that, the valve may not be opened for a long time. Even if the room temperature is high, if the floor surface temperature Tf decreases with time, it is uncomfortable and uncomfortable to use. In the second embodiment, it is possible to adjust the temperature so that the sensible temperature can be kept comfortable while taking into consideration such influences of solar radiation and other heaters.

The control circuit 14 reads the output signal of the heat medium temperature detection sensor 17 or the floor temperature sensor 21 in step 401 in the flowchart of FIG.
In step 402, it is determined whether or not there is an output signal from the heat medium temperature detection sensor 17 or the floor temperature sensor 21. When there is an output signal in step 402, the process of step 403 is performed, and when there is no output signal, the process of step 404 is performed. The process of step 403 is the same as in the first and second embodiments.
