The compressor accounts for most of the electric power consumption in refrigerators and air conditioners. To promote energy-saving, Toshiba has been progressively improving compressor efficiency. We have now developed a new "helical" compressor which has a new and unique compression mechanism. The helical compressor utilizes the compression mechanism of a spiral blade, the first such compressor in the world. Since it has no valves and realizes a continuous compression process, it achieves high efficiency, low noise, low vibration, and compact dimensions.This helical compressor is expected to be the next-generation compressor for the new century.
