Method and system for improve-efficiency air-conditioning
First Claim
1. A building air treatment system configured for use with a heating and air conditioning (HVAC) system of a building, comprising:
- an inlet configured to receive air from outside of an enclosed environment of a building for supply thereto;
an HVAC system configured to heat and/or cool an airflow received from the enclosed environment;
a controller;
at least one sensor configured to provide a signal determinative of a level of at least one contaminate contained in the air of the enclosed environment to the controller; and
a scrubbing system having at least one adsorbent,wherein the scrubbing system is configured to;
receive at least a portion of the airflow and expose the at least a portion to the adsorbent so as to reduce the concentration of the at least one contaminant in the air of the enclosed environment by adsorption thereof by the adsorbent, andreceive a purging substance and be cycled to purge the adsorbent so as to desorb the adsorbed at least one contaminate therefrom;
and wherein the controller is configured to control an intake rate of outside air into the enclosed environment based upon a level of the at least one contaminate in the air of the enclosed environment.

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.
