No way..

Using minimum 4 temperatures (max 15), 2 pressures (max 15), refrigerant flow and power transducers they are linked into a real time pressure enthalpy display for over 40 refrigerants CFC. HCFC, HFC HC and R717 giving an on screen PH diagram so you can trim systems.

The software also gives COP in refrigeration or heat pump mode. All load calculations in one go. Went on to link this to a compressor calorimeter.

Took months to develop (Tech Director did the hard sums)then I came to work here. Such is the quest for cash.
