Abstract

A method of operating a rolling piston compressor includes determining a pressure difference (ΔP) between a discharge pressure (P) within a compression volume and a suction pressure (P) within a suction volume; determining a pressure ratio (r) equal to the discharge pressure (P) over the suction pressure (P); estimating a discharge pressure (P) based at least in part on the pressure difference (ΔP) and the pressure ratio (r); determining that the discharge pressure (P) is greater than a predetermined pressure limit (P); and lowering a target speed (ω) of the rolling piston compressor.
