Convective air cooling techniques are facing a unique challenge in cooling of high power Components by removing high heat flux under space constrains, that brings limit in the size of the thermal solution. This paper presents an idea of combining the Conventional Vapour Compression Refrigeration concept with an innovative engineering approach by placing Mini Channel Heat Exchanger instead of Conventional Heat Exchanger in the system that can break the barriers to provide much compact and energy efficient refrigeration system. Characteristics of air conditioning system with Mini Channel Heat Exchangers under single amp; multi-phase fluid flow are analysed. So, a review has been done to understand different Parameters which affect the behaviour of fluid flow such as — mass flow rate, specific heat of fluid, heat transfer coefficient, pressure drop, heat flux, geometry of channel, dimensionless numbers and many such parameters that would play major role over here.
