The report describes a computer model, EVSIM, of a
refrigerant-to-air heat exchanger of the type used in
residential air conditioning as an evaporator. The model
provides performance predictions of a one-slab or
two-slab evaporator for a given refrigerant enthalpy at
the coil inlet, saturation temperature and superheat at
the coil outlet, and at imposed one dimensional air mass
flow distribution over the coil face. The model accounts
for air distribution and for complex refrigerant
circuitry designs by simulating refrigerant
distribution. Performance of the coil is calculated
employing a tube-by-tube scheme. The report includes a
User's Guide and a listing written in FORTRAN 77.
