Compound cooling system has common thermal component contg. evaporator in first circuit and liquefier in second circuit, heat exchanger transferring heat from first to second coolant

摘要

The system has two coolant circuits (1,2) with compressors (3,9), condensers (4,6), chokes (13,14) and evaporators (6,7,11) connected together in a conventional manner and each filled with a coolant. The first circuit has at least two evaporators and the second has a liquefier. One of the evaporators in the first circuit and the liquefier form a common thermal component that contains a heat exchanger for transferring heat from the first circuit's coolant to the second circuit's coolant and a cold storage device.
