Table 2 lists the thermodynamic performance characteristics of each refrigerant in a simple single-stage vapor compression cycle assuming a fixed compressor volumetric displacement operating between a saturated condensing temperature of 115[degrees]F (46.1[degrees]C) with 15[degrees]Fd (8.3[degrees]Cd) of subcooling and a saturated evaporating temperature of 40[degrees]F (4.4[degrees]C) with no compressor suction superheat.

The large swept volume of the newly designed pump head provides a greater volumetric displacement per revolution resulting in longer tube life and gentle handling of shear-sensitive fluids.
Simulations run with the software showed that the compression ratio and volumetric displacement numbers were lower than they should have been and helped identify the problem: that the roller position on the cams was critical.
