SCPTrefrigType

Overview:

Refrigerant type.  (Refrigerant name, A, B, C.) .   

This configuration property sets the refrigerant type used in a system. Its primary use is for temperature-pressure conversion.

The formula used is:

t = ___B___ - C
ln(p) - A

Where:

  • tis temperature in °C
  • pis the pressure in Bar absolute
  • A, B, C are constants defined for a particular type of refrigerant.

Refrigerant details and numbers are published by the US-based ASHRAE. The default values are manufacturer-defined.
