Appeal No. 1999-1778
Application No. 08/888,365
Han. Claims 27 and 28 depend from claims 24 and 26,
respectively, and
stand rejected as being unpatentable over Fujimoto in view of
Booth, Onishi, Symposium and Han.
With respect to claim 26, this claim, because of its
dependency on claim 11, requires that the heat exchanger tube of
the heat exchanger includes a convex portion and inner fins that
are asymmetrical. In that the reference to Han additionally
relied upon by the examiner in the rejection of this claim does
not make up for the deficiencies of Fujimoto, Booth and Onishi
in this respect, the rejection of claim 26 cannot be sustained.
Moreover, each of claims 26-28 calls for a refrigerating
circuit capable of operating in a heating mode or a cooling mode
and including a heat exchanger wherein, in the heating mode, the
heat exchanger functions as an evaporator and the flow
resistance therethrough is low, and, in the cooling mode, the
heat exchanger functions as a condenser and the flow resistance
therethrough is high. Thus, these claims tie the mode of
operation of the circuit and the corresponding functioning of
the heat exchanger to flow resistance through the heat
