Numerical Study on a Hybrid System by Using a Portable Air Conditioner

This paper presents a new design concept of hybrid air conditioning system by using aportable air conditioner to achieve a better personal control of indoor environment withoutsacrificing the responsibility to a sustainable environment. The results of the detailedcomputational flow dynamics (CFD) simulation in this study, through a systematic analysison the parameters of wall opening, outdoor wind speed and temperature, show that with anappropriate design of wall openings, this hybrid system can sustain a comfortableenvironment until affected by strong wind blast. At that moment, a suitable control of thesizes of these openings is suggested to extend the proper functioning of this hybrid system toachieve the dual benefits of comfort and energy conservation.
