Scroll chillers and multisc scroll compressors

摘要

The object of the present invention is to provide a twin scroll compressor (3) of the pressure difference class and a signal scroll compressor (4) of the differential pressure class type on the upper pressure surface by arranging the receiver (2) The control panel 5 is provided with auxiliary devices such as an oil separator 6 and an accumulator 7a and 7b at the upper rear portion thereof to constitute a multi-chiller. Further, each compressor is controlled by the signal of the suction pressure sensor 15. [;As a result, the upper and lower two stages of the scroll compressor can be stacked, space can be saved, and the logarithmic control can be performed without controlling the inverter, so that the energy saving effect is extremely large and can be manufactured at low cost.
