Could “Minimising the Head Pressure” be costing you more than you think?
Minimising the condensing temperature in attempt to save energy can have a negative effect on system running cost if not taking into account certain thermodynamic changes. As condensing pressure is reduced, the effect of flash gas in the liquid line rises sharply. 2% flash gas by weight in the liquid line at 38°C (F) condensing temperature will occupy 28% of the liquid line with vapour at 21°C (70F) condensing temperature. Flash gas produces no refrigeration effect, electronic expansion valves would simply open up wider in attempt to deliver cooler temperatures and allow this flash gas to pass through to the cooling coils. As a result, the compressors will require additional staging or cylinders to re-compressor this gas which has already been compressed once before. In summary, you could be wasting more than you think. View our minimising the head pressure slide show here.

In “Liquid Pressure Amplification” How is my power being wasted?
Present day designs with head pressure controls were developed some 65 years ago. Higher head pressures were designed into a refrigeration system so it would function well at lower outdoor temperatures. These higher pressures were needed to prevent flash gas and deliver the refrigerant to the refrigeration cooling coils. Power costs a half a century ago were not a factor so the added cost of operation with lower efficiency did not matter. At today’s power costs, inefficiency is an unacceptable part of ones refrigeration overhead. See Brochure: Improving-Refrigeration-Dynamics-LPA
