In the throat cutting era of competition which has its base in research and development every concept of
energy conversion is subjected to improvisation. With a view of above recent trend the performance of various thermal
equipments are subjected to research and development so as to increase the energy conversion from one form of energy
to another form. The following work represents research in the field of heat exchanger and specifically indicating
transfer of heat from higher to lower temperature. Since various fluids have been used to attend higher heat transfer, the
more efficient fluid is Nano fluid. In the present work the performance test on chiller unit had been carried out by using
Nano fluid. Water based Al2O3 (Alumina) has used as a coolant. The Nano fluid was prepared by using different
composition of water and Al2O3 nanoparticles and it used as the working fluid. The performance has checked by varying
the flow rate of Nano fluid in the condenser.
