Abstract
A refrigerant compressor group for a refrigeration system that includes least two piston compressors operating in parallel between a common low-pressure connector and a common high-pressure connector. To adjust it to different requirements, in a refrigerant compressor group, a variable overall mass flow throughput in the refrigerant compressor group is adjustable. For at least one of the piston compressors, its mass flow throughput is adjustable by speed selection using a frequency converter for the electric motor. For at least one of the piston compressors, its mass flow throughput is adjustable by cylinder selection. An operating condition controller for the refrigerant compressor group is provided which, on the basis of a performance request signal of the refrigeration system that is transmitted to the operating condition controller, controls the overall mass flow throughput by open or closed-loop control by predetermining the cylinder selection and the speed selection.
