Examples
Embodiment 1
[0148] The monthly electricity bills for each set temperature in Example 1 were 6,309, 4,173, and 3,165 yen, and if the daytime set temperature was lowered, the electricity bill was significantly reduced.
[0149] In the above-mentioned basic experiment 1, the monthly electricity bill was 16,800-11,400 yen. On the contrary, by adding sensible heat type heat storage material 20 to the heating plate P used in this basic experiment and giving a temperature difference between day and night, the temperature according to the time period was performed. control, thereby significantly reducing electricity bills as described above.
Embodiment 2
[0150] 2. Embodiment 2 (sensible heat type heat storage material)
[0151] This example uses the heating plate HP on which the same sensible heat type heat storage material 20 as in Example 1 is stacked, and shows the measured value when the average outside air temperature is 2°C in the temperature control according to the temperature difference and time interval.
[0152] time period: hours
[0153] As found in Comparative Examples 1 and 2, when the outside temperature is reduced from 13°C to 2°C, the electricity cost also increases by 40%-60%.
Embodiment 3
[0154] 3. Example 3 (latent heat type heat storage material + sensible heat type heat storage material)
[0155] This example shows measured values at an average outside temperature of 13° C. in the case of using both a latent heat storage material and a sensible heat storage material as the heat storage material in the temperature difference and time period temperature control.
[0156] used in figure 1 Floor heating device 16 ( figure 2 ), when the average outside temperature is 13°C, divide the set temperature into 3 sections as follows, and change the setting by changing the date, and measure the power consumption at this time, the results are shown below.
