*The total cooling power
comes from the
recovered heat, the pre-
treatment coil and the
direct expansion coil.
**The cooling power
referred to the internal
environment is generated
by the difference between
the inflow air enthalpy and
the room air enthalpy.
Negative values indicate
that the unit cannot
sustain the desired
conditions even without
internal loads.
