Volume efficiency is defined as the ratio of the actual volume of the refrigerant gas pumped by the compressor to the volume displaced by the compressor pistons. A high volumetric efficiency means ...

My Jan. 8 column covered refrigerant gas density coming into a compressor’s cylinder from the suction line and how it is affected by temperature. That column also covered how refrigerant density ...

Delta Hybrid is a synergy of blower and compressor technology that offers totally new opportunities for the generation of positive and negative pressure of air and neutral gases, owing to the ...

Compressor speed as a function of molecular weight, while maintaining the same suction and discharge pressure and mass flow rate. Polytropic head and efficiencies as a function of gas molecular weight ...
