Control pressure on the high pressure side in a cycle of transcritical vapor compression.

摘要

A cycle device vapor compression operating at supercritical pressure on the topside a circuit comprising a compressor (10), a gas cooler (11), an internal heat exchanger (12), a valve (14 ) A WELL low pressure refrigerant is additionally provided with means (5) for detecting at least one operating condition of circuit, preferably detecting a parameter representing the coolant temperature adjacent the outlet of the gas cooler (11 ).
