Cascade cooling device for use in ultra deep-freezer in laboratory, has evaporator whose one part with cooling medium line is connected to one of compressors and integrated into exchanger such that exchanger cools cooling medium

The device has two closed cooling circuits (1, 2) for conducting a cooling medium. Each circuit has a compressor (4, 10), a condenser (5), a dryer (6, 14) and a throttle (7, 15) that are connected with one another by a common cascade heat exchanger (3) such that the exchanger works as evaporator (17...
