Abstract

PURPOSE: To uniformize humidification in a case by making air cooled while passing through one evaporator converge with cooled air humidified while passing through the other evaporator in a cooling chamber to be supplied to a storage chamber from a blowoff port while preventing the mixing of the cooled air during the passage through both the evaporators with a partition plate. CONSTITUTION: A converging is made in a cooling chamber 3 between cooled air with a lowered temperature through a heat exchange with one evaporator, for example, a first evaporator 20 by which a cooling action proceeds and cooled air with raised humidity while passing through the other evaporator, for example, a second evaporator 21, in which a defrosting action proceeds immediately after passing through the respective evaporators 20 and 21. As a result, low temperature humid cooled air is produced and shunted to an inner route of a first opening 37, a first air path 35 and the first evaporator 20 and an outer route of a second opening, a second air path 36 and a second evaporator 21 in the cooling chamber 3 after sequentially passing through a blow off port 12, a storage chamber 2, a suction port 13 and the cooling chamber 3 to repeat one cycle of circulation within the low temperature case 1. This enables always maintaining of the cooled air humid at a low temperature while achieving a uniform cooling and humidification by one cycle a low temperature high humidity cooled air circulating through the low temperature case 1.
