Recently, from the viewpoint of global warming, we need to concentrate our effort on the improvement ofcompressor efficiency.We have developed a new capacity control technique, which is a combination of inverter drive and conventionalmechanical capacity control technique.We have achieved 10% lower energy consumption compared with our conventional scroll compressor(l) byimproving the efficiency for 15% when in the use of part load.This paper explains the combination of the inverter drive and mechanical capacity control structure of thecompressor and also the optimization of capacity control port with our high/low pressure housing and asymmetricscroll design.
