The following issues are addressed: (a) Is suppression
of nucleate boiling an appropriate physical mechanism to
explain experimental heat transfer coefficient behavior?
(b) Is suppression possible under reasonable conditions
with refrigerants? (c) Is suppression more or less
likely with a binary mixture of refrigerants as compared
with either pure fluid? Issue (a) is resolved in favor
of traditional suppression theory by critical review of
the literature. Issue (b) is resolved by experimental
evidence suggesting one must have rather low pressures
to suppress nucleation with refrigerants. Issue (c) is
resolved by experimental and correlative evidence
suggesting systematic differences with mixtures.
