The target time corresponds to the start time of use of the room, the end time of midnight power, and the like. In this heat storage type floor heating system, it takes time for the floor to store heat.Therefore, it is necessary to foresee how long it will take for the floor to heat up to the target temperature. Also, the power is turned on earlier for that time to start heat storage. For that purpose, it is necessary to determine the temperature rise gradient of the floor heating system in order to set the time when the power is turned on.

Further, the temperature rising gradient α of this floor heating system is represented by a solid line. Then, when the floor temperature before the power is turned on changes along the dotted line, the power may be turned on at time t 1 when the solid line and the dotted line intersect. When the floor temperature is higher than the temperature indicated by the solid line, it is not necessary to energize the floor heating system. In other words, if the energization starts earlier than the time t 1 , the floor temperature becomes higher than T 0 at the time t 0 , and the power consumption is wasted. On the other hand, if the energization is started later than the time t 1 , the bed temperature does not reach T 0 at the time t 0 .

Since the temperature rise gradient varies depending on the season, when a particularly accurate temperature rise gradient is required to optimize the decision of power-on, experiments are carried out over several days to investigate changes in underground temperature due to climate change and indoor environment. The influence of the change of the heating load due to the change of the temperature on the heating gradient of the floor heating system was measured.

ムの運転が開始する。In the above system, the procedure for determining the temperature rise gradient is as follows. That is, 1) The target bed temperature T 0 is input to the storage unit 7 by the input device 9. 2) The floor temperature is measured by the floor temperature detector 10, and the measured floor temperature is sent to the memory circuit 3 and stored therein. The counter of the timer circuit 4 is started at the same timing as the start of measurement. 3) The energization determination circuit 6 causes the target floor temperature T 0 stored in the storage unit 7 almost at the same time as the start of the measurement of the floor temperature.
And the comparison with the measured bed temperature stored in the memory circuit 3 are started. When the measured bed temperature is lower than the target bed temperature T 0 ,
In response to an instruction from the energization determination circuit 6, the floor temperature controller 8 operates to start energizing the heat storage device (not shown) with 100% of its capacity. The temperature at this time t 1 is T 1 .
The comparison between the measured floor temperature and the target floor temperature T 0 in the energization determination circuit 6 is constantly performed while the floor temperature is being raised by energization. Time t at which the measured bed temperature reaches the target bed temperature T 0
At 0 , the floor temperature controller 8 operates so as to stop energization of the heat storage device according to an instruction from the energization determination circuit 6. At this point, the counter value of the timer circuit 4 (t 0 -t 1 : corresponding to the energization time for temperature rise) is stored in the storage circuit 3 according to an instruction from the energization determination circuit 6. 4) The arithmetic circuit 5 stores the measured bed temperatures T 1 and T 0 at the start of energization t 1 and the end of energization t 0 stored in the storage circuit 3 and the counter value (t) of the timer circuit 4, respectively.
From 0 -t 1), heating gradient α (= (T 0 -T 1 ) / (t
0 -t 1)) is calculated. The calculation of the temperature rising gradient by the arithmetic circuit 5 is performed every time the floor heating system is operated, and the temperature rising gradient α is stored in the storage circuit 3. 5) When the temperature rise gradient α is stored in the memory circuit 3 and then a new operation is performed, the arithmetic circuit 5 averages the temperature rise gradients for the latest several days from several days before to the previous day, and the average is calculated. Adopt a heating gradient α av . In this case, to explain with reference to FIG. 2, since T 0 and t 0 are set, the bed temperature decreases to T 1 , and the dotted line indicating the change in the bed temperature is the solid line determined from the average temperature rise gradient α av. The operation of the underfloor heating system is started at the time point t 1 when it intersects.

By doing this, changes in the underground temperature due to changes in the climate from early winter to severe winter and early spring, and changes in the heating characteristics of the floor heating system due to changes in the heating load due to movement of indoor personnel and furniture. , So that it will be reflected in the operation so that there is always an optimal temperature rise gradient,
The power-on time can be set.
