Total Enthalpy Heat Recovery System. For total enthalpy heat-recovery systems the heat recovered can be expressed as. H = 4.5 q (h 2 - h 1) η (2). where. h 1 = air enthalpy of the exhaust air before the heat recovery unit (Btu/lbºF). h 2 = air enthalpy of outside air after the heat recovery unit (Btu/lbºF).
