Simulation results and consideration

To give one example, Table 1 shows the areal seasonal average natural room temperature of each room in the un-air-conditioning case. From Table 1, for various areas in each room the decrease rate of natural temperature in perspiration mode to non-perspiration becomes bigger as the specific sense temperature lowers. As an example, from Table 1, the maximum temperature decrease at the sense temperature 20 °С becomes 1.1 °C(E/U) in Sapporo, 1.3 °С (E/U, Children) in Tokyo, 1.6 °С (E/U) in Osaka and 1.5 °С (E/U, Children) in Naha. Table 2 shows the decrease rate of sensible heat load (energy-saving rate) due to autonomous perspiration = 1 — (heat load in perspiration mode / heat load in non-perspiration mode). The energy-saving rate by autonomous perspiration also becomes bigger as the sense temperature lowers. It is 72.3 (sense temperature of 20 °C)-24.4%(sense temperature of 40 °С) in Sapporo, 30.6-11.4% in Tokyo, 31.2-12.9% in Osaka, and 24.2-10.0% in Naha, especially bigger in Sapporo.
