Abstract
A compressor system includes: at least one variable-speed compressor, at least one fixed-speed compressor, a main suction pipe and a main discharge pipe; respective suction pipes of the variable-speed compressor and the fixed-speed compressor are connected to the main suction pipe in parallel, and respective discharge pipes of the variable-speed compressor and the fixed-speed compressor are connected to the main discharge pipe in parallel. The main suction pipe is configured with an oil-gas separation fitting structure, and the oil-gas separation fitting structure is designed to enable most oil of oil-gas mixture from the main suction pipe to move into the variable-speed compressor, and to make the variable-speed compressor stay in an oil-rich state.
