ABSTRACT:
A refrigerating system for generating low temperatures has one high-temperature region refrigerator sub-system and one low-temperature region refrigerator sub-system. The low-temperature region refrigerator sub-system has at least one expansion space defined internally of a first bellows and at least one compression space defined internally of a second bellows. Each bellows is expanded and contracted by a respective connecting member coupled to a power source. A working medium provided in the low-temperature region refrigerator sub-system travels through a flow path between the compression and expansion spaces inside the respective bellows. Means are provided for bringing the maximum pressure of the working medium to a value below its critical pressure, or for bringing the critical pressure of the working medium to a value between its maximum and minimum pressures, thereby liquifying some or all of the working medium in the at least one expansion space.
