Abstract: PURPOSE:To make the capacity of a thermal medium reservoir tank small to reduce a cost of equipment by partitioning the thermal medium reservoir tank with a movable partition into a high-temperature thermal medium storage section and a low-temperature thermal medium storage section. CONSTITUTION:A thermal medium reservoir tank 21 is partitioned vertically by a movable partition 22 into an upper high-temperature thermal medium storage section 21a and a lower low-temperature thermal medium storage section 21b.
