High efficient compressor is an important element to move R744 application line further south. Christian Schmälzle from Obrist Engineering presented a prototype 100kWel R744 piston compressor for commercial refrigeration and large capacity heat pumps developed in cooperation with SINTEF Energy. This first prototype of the 100kWel combines a high efficient compact permanent magnet motor, improved valve system for high speed and speed controlled flow modulation. A test conducted in specially build facility indicated after more than 500 hours of operation that efficiency gains of 10% in comparison with competitors are possible.
