Abstract:
1. A refrigerating device which is provided with a refrigerating unit including a refrigerant circuit comprised of a compressor, a high-pressure-side heat exchanger, and a low-pressure-side heat exchanger and which supplies, by a blower, cold air subjected to heat exchange with the low-pressure-side heat exchanger to an insulated space to be cooled, said insulated space being constituted in a main body, said refrigerating device to cool the insulated space, said refrigerating device comprising the main body structurally comprising an insulating top surface and an insulating bottom surface with an insulating back surface and opposing insulating side surfaces structurally connecting the insulating top surface and insulating bottom surface, and enclosing the insulated space to be cooled, a mechanical chamber structurally comprising a bottom surface with a back surface and opposing side surfaces structurally extending upwardly from the bottom surface, said mechanical chamber being disposed under the insulating bottom surface of the main body and structurally connected to the main body, the insulating bottom surface of the main body extending across the bottom of the main body to separate the main body from the mechanical chamber, in a vertical direction, said insulating bottom surface of the main body defining a suction port and a discharge port communicating with the mechanical chamber, a unit base, having disposed thereon the compressor and the high-pressure-side heat exchanger, said unit base being seated on the bottom surface of the mechanical chamber and spaced in a vertical direction from the bottom surface of the main body, and a refrigerating box, having hooks, in which the low-pressure-side heat exchanger and the blower are stored, said refrigerating box is not disposed on said unit base but is supported by the hooks from the insulating bottom surface of the main body so that substantially the entire weight of the refrigerating box and the stored low-pressure-side heat exchanger and blower is supported by the insulating bottom surface of the main body so as to communicate with the space to be cooled, wherein the refrigerating box is detachably attached by the hooks to the insulating bottom surface of the main body so as to be removable through a side surface of the mechanical chamber, and a refrigerant pipe disposed between the compressor or the high-pressure-side heat exchanger on the unit base and the low-pressure-side heat exchanger in the refrigerating box is constituted of a flexible tube that allows setting the refrigerating unit, pipe-connected beforehand and sealed with the refrigerant, in the mechanical chamber and then engaging the hooks of the refrigerating box with the bottom surface of the main body.
