Abstract

A multi cascade cooling system is disclosed, having a refrigerant flowing in refrigerating components, that comprises at least one first heat-exchanger configured to receive the refrigerant from a component of the refrigerating components and cooling it with a first fluid provided by a sorption machine and at least one second heat-exchanger configured to receive the refrigerant from the at least one first heat-exchanger and regulate a temperature of the refrigerant with a second fluid provided by an auxiliary cooler. The refrigerant flows from the at least one second heat- exchanger to another component of the refrigerating components.

Description

technical field [0001] The subject matter of the present disclosure relates generally to refrigeration. More specifically, the disclosed subject matter relates to energy efficiency improvements in cooling systems. Background technique [0002] Commercially available cascade units typically consist of one or more single-circuit refrigeration units, where each unit includes a compressor, evaporator, condenser, expansion valve, and heat exchanger. Typically, cascaded units represent dual-circuit cooling units, so each cascade has a different cooling capacity. Heat pumps can operate with various refrigerants in a cascade cycle, such as air-precooled units using air as heat carrier, while the primary cooling circuit consists of a compressor, condenser, evaporator and three-stream heat exchanger. Such commercially available cascade units employ an auxiliary compressor, condenser, and evaporator that can be connected to a three-stream heat exchanger. [0003] Two or more electri...
