Abstract: The use of air curtain in residential or commercial building has been increased substantially since last decades. The air curtain not only prevents air exchange between outside and inside environment of a building to decrease heat load, but also prevents dust and insects to enter into the building. The performance of air curtain is enhanced by minimizing infiltration rate of outside air. The researchers have emphasized on air curtain supply speed and angle to control its function. Computational fluid dynamics (CFD) is suggested by almost all researchers to analyze it at full scale, because it is very difficult to analyze experimentally. CFD coupled with multizone approach is very effective to evaluate the performance of an air curtain accurately. There is abundant literature on enhancement of air curtain performance for cold continents, like European countries, USA etc. The performance of an air curtain is highly dependable on climate conditions. A rigorous analysis is required for warmer regions where greater temperature difference exists, like India.
