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 ...
The capacity of a compressor is measured in Btu per hour (Btuh) or Btu per minute (Btu/min). Remember, there are 12,000 Btuh or 200 Btu/min in one ton of refrigeration. The capacity of a piston-type ...
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 ...
