Experimental Analysis of Air-Water Heat Exchanger with Microchannel Coil Exposed to Different Working Parameters

In this study experimental analysis of heat exchanger with microchannel coil (MCHX) has been done. MCHX have already been proven as key for improvement of outdoor condenser units in domestic space cooling systems. Many questions still exist in case of their implementation as evaporating unit, or in case of both single and multiphase fluid flow. In this study MCHX is used as air- water heat exchanger. An open circuit wind tunnel has been used for testing the MCHX in this non-standard application. The experimental analysis has been performed for a range of various water/air velocities and temperatures. Water temperatures and velocities, as well as air temperatures, velocities and pressure drops, were measured using data acquisition system with developed application in Labview software. Influence of water/air inlet temperatures and velocities on heat transfer in the heat exchanger with microchannel coil has been investigated.
