Abstract :
This proposed research titled, Air
Refrigeration Methods for Comparison Simulation
Bench, is a new technique to yield coefficient of
performance (COP) of refrigerants, mechanical energy,
generate low heat energy with an optimal current
discharge in dissimilar metals. First law of
thermodynamic states that the net heat supplied from
the system to the surrounding should be equal to the net
work done when temperature and pressure do not
change the enthalpy of the system (Hess law). The
temperature, pressure as well as rate of cooling of
compressed Freon 12 refrigerant or ammonia from the
condenser will be metered with respect to the vapour
absorption, vapour compression and thermoelectric
refrigeration systems that are integrated into the
simulation bench. Also, air bubble, which causes
pressure system lag when the temperature increases in
an expansion valve, will be addressed measurably with
the help of heating cylinder. This air refrigeration
comparison simulation bench yielded a highest
coefficient of performance 1.63 vapour compression
cycle , followed by vapour absorption cycle with 1.55
and least with 1.27 in thermoelectric refrigeration.
