Hello All,

I am trying to determine the impact that various energy conservation measures(ECM) have on the required refrigerant charge in a supermarket central refrigeration system. That is if they increase, decrease or have no affect on the design refrigerant charge. Is there a way to figure this out from the outputs of E+, doe2.2R or engineering calculations? The ECMs that I am looking at are floating head pressure, liquid heat exchanger, mechanical subcooling, condenser specific efficiency.

Thank you,

Haider.
