Air curtains save energy over vestibules, says AMCA
AMCA has revealed the results of a study that documents the energy savings available from using air curtains as an alternative to, or in conjunction, with doors and vestibules.
The Air Movement and Control Association said the study used computational fluid dynamics and whole-building-energy analysis of the DOE Medium Office reference building model for three different building entrance scenarios. They were: one single door without vestibule or air curtain; a single door equipped with an air curtain; and a single door with a vestibule.
