Abstract: A showcase where an illumination device is placed outside a receiving chamber to enable effective use of the space in the receiving chamber. The inside of an insulated box body (16) having front glass (18) fitted in a front opening (56) is defined to form a receiving chamber (52). An upper evaporator (34) is placed in an upper insulating layer (54) of the insulated box body (16) so as to be in contact with a cooling plate (62) defining the upper surface of the receiving chamber (52). An opening (64) is formed in that portion of the cooling plate (62) with which the upper evaporator (34) is not in contact, and a receiving space (66) is formed in that portion of the upper insulating layer (54) to which the opening (64) faces. A holder (78) is placed at the receiving space (66), and inside the holder (78) is received and fixed an LED illumination device (70). The opening (64) is closed by a cover (86) with packing (84) in between, and the inside of the holder (78) is maintained in a sealed state.

Abstract: A low temperature storage cabinet wherein a heater is embedded in an opening frame structure of the cabinet to prevent the occurrence of dewfall on a surface of the frame structure to be brought into contact with a door hinged to the cabinet body, and wherein operation of a compressor is controlled in accordance with an inside temperature of the cabinet to maintain the inside temperature of the cabinet at a predetermined value. In the storage cabinet, the heater is activated synchronously in response to operation of the compressor and is activated in accordance with outside humidity or inside temperature of the cabinet during stopping of the compressor.

Abstract: A low temperature storage cabinet having a freezing cycle system composed of a compressor, a condenser, a throttle and an evaporator, a cabinet temperature sensor for detecting an inside temperature of the cabinet, and an electric fan provided in the cabinet for circulating cooled air in the interior of the cabinet, wherein the compressor in the freezing cycle system is activated in response to rise of the inside temperature of the cabinet and deactivated in response to a fall in the inside temperature of the cabinet, and wherein the rate of operation of the electric fan is decreased in accordance with a decrease of temperature or pressure of refrigerant in the freezing cycle system during deactivation of the compressor to thereby reduce consumption of the electric power.
