Net Refrigeration Effect is
"the quantity of heat that each pound of refrigerant absorbs from the refrigerated space to produce useful cooling"
Net Refrigeration Effect can be calculated as
NRE = hl - he (1)
where
NRE = Net Refrigeration Effect (Btu/lb, J/kg)
hl = enthalpy of vapor leaving evaporator (Btu/lb, J/kg)
he = enthalpy of vapor entering evaporator (Btu/lb, J/kg)
