Abstract
A refrigerant systemD comprises a heat insulating housingprovided with an accommodating space inside and a refrigeration unitattached to a lower portion of the heat insulating housingin which a compressora gas cooleran internal heat exchangera restriction meansand an evaporatoraccommodated in a heat insulating caseA are disposed on a unit baseThe gas coolerand the heat insulating caseA are disposed so that air heat-exchanged by the gas coolermoves toward the heat insulating caseA, an air passage T is provided between the unit baseand the heat insulating caseA, the air heat-exchanged by the gas cooleris passed through the air passage T to be discharged outside, and the internal heat exchangeris disposed in such a manner that it is embedded in a heat insulating material layerC provided around the heat insulating caseA to be provided with a heat insulation property. Accordingly, exhaust heat-exchanged by the gas cooler is discharged outside without stagnation, and increases in an overload and operation power of the compressor are suppressed and the durability of the compressor can be improved. Further, the heat-exchanging efficiency of the internal heat exchanger can be improved and the generation of condensation on a surface of an outer side tube of the internal heat exchanger can be prevented.
