500°F Absorption Heat Pump Under Development

Show full item recordAbstract
Economic industrial heat pumping to temperatures above 500°F (260°C) is promised
in the near future. A new absorption fluid is the key. Tested under DOE sponsorship,
the new fluid has proven to be thermally
stable and noncorrosive to austenitic
stainless steel up to 500°F, or mild steel
up to 430°F. Heat transfer properties are
comparable to those of the conventional
LiBr-H20 system. Paired with water as the
working fluid, laboratory tests have shown
that useful temperature lifts of over 162°F
(90°C) ∆T can be achieved allowing 10°F
heat exchangers. The fluid is nontoxic and
noncombustible. Good economics for the
system should stem from (1) high temperature
capabilities for wider and more highly
valued uses, (2) high internal temperature
lifts for low heat exchanger surface areas,
(3) predominantly carbon steel components,
and (4) better COP in the heat amplifier
mode than current absorption heat pumps.
Recent laboratory results are presented
including temperature applicability maps.
