Net Refrigeration Effect

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 = h_l - h_e                                           (1)

where 

NRE = Net Refrigeration Effect (Btu/lb, J/kg)

h_l = enthalpy of vapor leaving evaporator (Btu/lb, J/kg)

h_e = enthalpy of vapor entering evaporator (Btu/lb, J/kg)
