Combination re-conditioning unit and illuminating appliance for use with central air conditioning system

摘要

A central air conditioning system for a multistory, multiroom building is arranged with a local re-conditioning unit mounted within a ceiling chamber of the building and combined with an illuminating appliance. Air in the space to be air conditioned is admitted to the re-conditioning unit through an air inlet opening formed in the illuminating appliance and is withdrawn from the re-conditioning unit into the space to be air conditioned through an air outlet opening also formed in the illuminating appliance.
