Abstract
A first bypass valve ( ) that sets discharge capacity to 60% is provided in a first scroll of an asymmetrical spiral-type scroll compressor. Also, a second bypass valve ( ) that makes suction side and discharge side communicated with each other so that set load of the compressor becomes 50% is provided outside a scroll of the first scroll ( ). In this way, by closing the first and second bypass valves ( ), effective load of the compressor is set to 100%. Also, by opening the first bypass valve ( ) and concurrently closing the second bypass valve ( ), the effective load of the compressor is set to 60%. Further, by opening both the first and second bypass valves ( ), the effective load of the compressor is set to 30%.
