Method and system for improved-efficiency air-conditioning

Abstract

Systems and methods for circulating air in an enclosed environment are disclosed. In some embodiments, the system includes an inlet to receive air from outside of the enclosed environment and an air handling unit coupled to the inlet and also configured to receive 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.

What is claimed is: 
     
         1 . A system for circulating and treating air of an enclosed environment, comprising:
 an inlet configured to receive air from outside of the enclosed environment;   an air handling unit configured to receive air from at least the enclosed environment and supply air into the enclosed environment; and   a scrubbing system in gaseous communication with the air handling unit which includes at least one adsorbent,   wherein the scrubbing system is configured to reduce the concentration of at least one gaseous contaminant in the air the enclosed environment by adsorption thereof by the adsorbent.
