Cooling System and Respective Operation

Abstract

The present invention relates to a method for operating a cooling system of a laboratory device, wherein the cooling system (4) comprises a compressor assembly, comprising at least a first compressor (30), a cooling device (32), an expansion device (34), and an evaporator (36), which are fluidly connected to form a main cycle, and wherein the cooling system further comprises a refrigerant circulating through the main cycle. The method comprises operating the compressor assembly based on a compressor control loop for controlling a compressor controlled variable xc(t) based on a compressor reference variable wc(t) and a compressor feedback variable rc(t), and the method further comprises operating the expansion device based on a superheat control loop for controlling a superheat controlled variable xs(t) based on a superheat reference variable ws(t) and a superheat feedback variable rs(t).
