Patent attributes
Systems and methods for circulating air in an enclosed environment are disclosed. An inlet can be provided to receive an outside air from outside of the enclosed environment and an air handling unit coupled to the inlet to receive the outside air through the inlet and configured to receive a circulated air from the enclosed environment. The air handling unit can be configured to affect a temperature of at least one of the received outside air and the received circulated air. Based on the received outside air and the received circulated air, the air handling unit can be further configured to generate air for supplying to the enclosed environment. The current subject matter system can also include an air circulation system configured to circulate the generated air from the air handling unit to the enclosed environment and back to the air handling unit and a scrubbing system coupled to at least one of the air handling unit and the air circulation system and configured to reduce presence of at least one substance in the air supplied to the enclosed environment.
