Liquid Pressure Amplification
Liquid Pressure Amplification (LPA) Overview
Patented in the USA, LPA was developed to allow refrigeration
equipment to operate at more efficient levels.
It is well known that refrigeration efficiency improves as discharge pressure is reduced, this is commonly referred to as floating head pressure and is advocated in many Carbon Trust publications (click here for downloads)
For example, take the manufacturers figures for a typical reciprocating compressor
It can be seen that by reducing discharge pressure by 5 bar, capacity has increased by 21.8%, absorbed power has reduced by 19.9% and COP (efficiency) has improved by 52%.
LPA allows these levels of efficiency to be achieved.
