Abstract
A spherical expansion compressor adapted to variable working conditions with a spherical inner chamber, comprises a rolling rotor compressor used as first-stage compression, compression working chambers, expansion working chambers, a gas tank and a pressure control circuit. The pressure control circuit is between the gas tank and a pressure-controlled inlet valve of the rolling rotor compressor, and controls the inlet valve to open/close according to pressure in the gas tank and maintains constant pressure in the tank. A working medium after first-stage compression enters the gas tank, where the pressure control circuit regulates the gas tank pressure. The working medium enters second-stage compression, and expands in the expansion-stage, forming the spherical expansion compressor adapted to variable working conditions.
