Abstract
A desiccant tank storing desiccant is accommodated in a thermal insulation case, and a desiccant tank-side ventilation duct is formed between the desiccant tank and the thermal insulation case. Ventilation path change-over dampers are provided to switch a ventilation path of the desiccant tank-side ventilation duct to an interior heat release operation path or an exterior heat release operation path. A thermal insulation case accommodates a water tank storing water therein and connected with the desiccant tank through a connection pipe without using valves. A water tank-side ventilation duct is formed between the water tank and the thermal insulation case. Ventilation path change-over dampers are provided to switch a ventilation path of the water tank-side ventilation duct to an interior heat absorption/radiation operation path or an exterior heat absorption/radiation operation path.
