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.
