PURPOSE:To reduce a thermal radiation from a thermal accumulation material as well as to improve an efficiency of thermal accumulation by a method wherein partition plates are arranged in order to divide an inside part of a casing and a suction port into one for an evaporator and the other for a condensor. CONSTITUTION:A partition plate 12a is arranged at an evaporator side of a suction port 13 at a central lower part of a casing 2 from a bottom plate upwardly, an upper part of the casing is opened to form a suction port 14 for the evaporator. At the side of a condensor, a partition plate 12b is arranged from a top plate of the casing 2 downwardly. The lower part of the casing is opened to form a suction port 13 at the side of condenser. The partition plates 12a and 12b are preferably made of thermal insulation material. As a result, even if a fan 8 is stopped during a thermal accumulation work, air is not sucked from a cold air discharging port 11 due to the presence of the partition plates 12a and 12b. An efficiency of thermal accumulation is improved and the suction port 14 at the side of the evaporator is opened at the upper part of a spacing 15 at the evaporator, so that air of low temperature is accumulated at the lower part of the spacing 15 of the exaporator and so a thermal radiation of the thermal accumulation plate can be decreased. |
