The air curtains are used as a seal to prevent the infiltration through display cabinets and consequently energy is decreased. The relative humidity plays an important role in cooling load of display cabinets. This work aims to present an experimental and numerical study of the influence of ambient relative humidity on the two air curtains in multi-deck display cabinet at different temperature and comparing the results with a single air curtain. For validation, the present work results are obtained by using computational fluid dynamics (CFD) code (Fluent6) and compared with previous researches.
