In our aim is enhancing the efficiency of industrial air conditioning system with nano particle to increase the
coefficient of performance. Due to the increase in machine technology and there is a lot of new innovation of air conditioner
and its components, to make sure the proper running of machinery system, air conditioner and its cooling system. In this work
planned to build a chilled water air conditioning system (HVAC) to reduce the improper working of the air conditioner which
required cooling. This chiller plant is play a major role in these works and its benefits. This chiller plant system can used in the
required places and reduce the power consumption. To avoid the environmental issue the water is flowing through the inside the
air conditioner system to make sure the cooling water temperature. Introducing a ZnO as the nano particle, this nano particle
have a good thermal conductivity, the heat transfer of the chiller plant system increases when the use of nano particle.
