PURPOSE:To prevent heat loss and dew condensation caused by heat radiation, and to prevent fluctuation in refrigerating cycles caused by the change in environmental temperature, by making the refrigerator unit of an air conditioner including a cylindri cal water heat exchanger on the supply side, a liquid reservoir housed in the hollow space of a heat exchanger, an accumulator, and a compressor to heat-insulating struc ture, by covering all those sections with foamed heat insulation material in one body as a whole. CONSTITUTION:All constituent sections for refrigerating cycle encircled by dotted lines, including a water heat exchanger 3 on the supply side, a low pressure accumulator 6, a compressor 7 and a liquid reservoir 15, are made of heat-insulating structure, a completely insulated from atmosphere, as the sections are foam-molded in one body by a foamed heat insulation material 16 such as foam urethane. Because all sections of a refrigerator unit are completely insulated from open air as a whole, the refrigerator is not affected by the environmental temparature, and energy loss and dew condensation caused by heat radiation are none in it. The size of a refrigerator can be made compact as a whole by utilizing a hollow space. Besides, pipings and units are free from vibration and resonance, because mechanical vibration transmitted from a power system is absorbed by the heat insulation material. As a result, stabilized performance can be obtained in an air conditioner.
