It’s a problem all operators face: if I lower the head pressures in my refrigeration systems, I can lower operating costs. On top of that, I can meet the Department of Energy’s 2017 energy reduction targets. But, how do I do that with existing technologies?
Some in the industry have tried using thermal expansion valves (TXV) to lower head pressures, but TXVs can’t maintain capacity and digest flash gas that forms when pressures float lower. So operators are still forced to keep head pressures near 105 °F.
