Numerical study of heat transfer performance on the air side of evaporator for split air conditioning systems

The aim of this study is to investigate the evaporator?s heat transfer performance with air flow characteristics in split air conditioners' indoor unit, which have an increasing number of usage in houses and workplaces due to climatic changes, numerically. Thus, indoor unit is modeled using Computational Fluid Dynamics and Heat Transfer (CFDHT) method and analyses were made. Results of the numerical study are compared with the measurements made by the producer company. So, it was possible to determine the temperature and velocity distributions and heat transfer performance without experimental tests which are expensive and take long time. The success of this study is to develop a numerical method to analyze split air conditioner indoor unit heat exchanger performance with heat transfer and air flow together.
