Zusammenfassung: | FIELD: technology of production of cold. ^ SUBSTANCE: proposed method is used for cooling the air contained in isolated cavity; air to be cooled is directed to compressor where it is compressed at rise of temperature; then, compressed air is directed to heat exchanger where it is cooled at constant pressure and then it is directed to gas-expansion machine where it is expanded and its temperature is lowered, after which it is directed to isolated cavity. Cooling the compressed air in heat exchanger is effected through heat exchange with surrounding medium. Depending on ambient temperature, area of heat-exchange surface is varied between compressed air to be cooled in heat exchanger and surrounding medium. Temperature of cooled air at the gas-expansion machine outlet is changed to preset level. ^ EFFECT: possibility of maintaining required temperature conditions in isolated cavity; enhanced energy efficiency of process. ^ 10 cl, 3 dwg |
