Compretion Refrigeration Machine
is very commonly
used, either for home or industuial scale. The pefomance
of machine is depend on the quality of the fluid (refigerant) that operated.
The refrigerant that usally used is R -12 that have very good
thrmoynamic properties. In
fact this refrigerant
came from the
CFC‟s (Chlorofluoride
Carbonate), is the
substance which have
potency to detruct
the inviromenthal system. From that writer tend to do research that
concern with same alternative
refrigrerant. They are
R-134, Butana and
Petrozon. The perfomance that
result from machine than compared with the perfomance of refrigeration machine that
operatet with R-12 refrigerant. Research activity begun with instaling refigerant
machine complatet with
experimanthal divice and
control system. Using
the R-12 refrigerant, the
maximum COP is
2.21. The COP
of refrigeration machine
that operated with alteranative refrigerant are:
- For Butana the maximum COP is 2.1 at low cooling load and evaporator pressure 2.6 bar
- For R-134a the maximum COP is 2.4 at high cooling load and evaporator pressure 1.2 bar
- For Petrozon the maximum COP is 2.2 at high cooling load and evaporator pressure 2.6 bar
