は約２０分となる。Here, when the outside air temperature is set to 20°C and the heat storage temperature level is set to 65°C, the heat storage capacity for the vl containers 13 is 0.96 kcal for latent heat and 0.26 kcal for sensible heat.
The total amount is 1.22 kcal, and since 18 containers 13 are used in total, the total amount is 22.0 kcal. It takes about 20 minutes to store this amount of heat in an adiabatic state.
次にこの蓄熱式電気ヒータは局所暖房器の１つ５べＳ である電気チョッキのヒータとして用いる事ができる。Next, this regenerative electric heater is one of the local heaters. It can be used as a heater for electric vests.

持続することができた。As a result of embedding this heat storage type electric heater in the insulation material of the vest, the vest becomes warm (28W) when the power is turned on.
The temperature of the latent heat storage material reaches the set temperature of 65℃ in 30 minutes after turning on the power (heat dissipation), and even if the power is turned off at this point, the heat retention state (28W heat dissipation) will continue for the next 46 minutes. I was able to do that.

On the other hand, when the heat storage type electric heater of the present invention (heater power: 80 W, heat transfer capacity: 22 kcal) is used, the heat retention function can be maintained even after the power is turned off. In other words, it is possible to achieve co-addressing of the power supply cords. Furthermore, the non-heat generating part has a 7 lexiple shape, so it fits your back when worn.
