R22 and R410A split air-conditioning systems were tested
and compared as outdoor temperature ranged form 27.8 oC
(82.0 oF) to 54.4 oF (130 oF). The R410A system tests
were extended t 68.3 oC (155.0 oF) ambient temperature
with a customized compressor. Capacity and efficiency of
both systems decreased linearly with increasing outdoor
temperature, but the R410A system performance degraded
more than the R22 system performance. Operation of the
R410A system was stable during all tests, including
those with the customized compressor extending up to the
68.3 oF (155.0 oF) outdoor temperature and resulting in
a supercritical condition at the condenser inlet. No
noticeable changes in noise level or operation on the
system was noted.
