Development of 112w Vapour Absorption Refrigeration System for Cars

Nicholas Akhaze Musa, Emenke Iwunze

Abstract


Twentieth century vehicles and some twenty first century vehicles were not manufactured with the provision of a car refrigeration system. Incorporating vapour compression refrigeration system in these vehicles will pose problems because their engines were not designed to carry the load which the present car refrigeration system operating on the vapour-compression cycle employs. So a car refrigerating unit which operates on the principle of vapour absorption refrigerating system, using exhaust heat as its energy for operation, was designed and constructed.  The major parts of the refrigerating system are the evaporator, condenser, generator and absorber and their capacities were determined to be 112W, 111W, 210W and 440W respectively. On performance evaluation, using water and ammonia as absorbent and refrigerant respectively as the working fluid, the refrigerator was able to achieve an evaporator temperature of 21o C and had actual Coefficient of Performance (COP) of 0.32. Although the actual coefficient of performance of the refrigerating system is low, it is still useful for keeping passenger consumables fresh and cool throughout a journey.
