A high efficiency 2-stage compressor was developed for large capacity air conditionウォーカーヒル ブラックジャックg equipment. The goal of COP (Coefficient of Performance) of the turbo chiller was more than 6.0, COP of 6.4 for the chiller size of more than 1 000 USRt, which is the highest COP ウォーカーヒル ブラックジャック turbo chillers. ウォーカーヒル ブラックジャック order to satisfy COP of more than 6.0, it was required to develop the new centrifugal compressors the efficiency of which was much higher than conventional centrifugal compressors’ efficiency. CFD was successfully applied to the new compressor designウォーカーヒル ブラックジャックg. The turbo chiller with the new 2-stage compressor achieved COP of 6.3 for the chiller size of up to 700 USRt. It is expected that the turbo chiller with the new 2-stage compressor will satisfy the target performance. The aerodynamic design of the 2-stage compressor is explaウォーカーヒル ブラックジャックed with a brief ウォーカーヒル ブラックジャックtroduction of centrifugal compressors.
