Method and system for improved-efficiency air-conditioning
First Claim
1. A system for circulating air in an enclosed environment, comprising:
- an inlet configured to receive air from outside of the enclosed environment;
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 is 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 is further configured to generate air for supplying to the enclosed environment;
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;
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, wherein the scrubbing system includes at least one adsorbent, and wherein a concentration of the at least one substance is reduced by adsorption of the at least one substance onto the adsorbent.

Abstract
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.

16. A process for circulating air in an enclosed environment, comprising:
-
receiving an outside air from outside of the enclosed environment and a circulated air from the enclosed environment; conditioning at least one of the received outside air and the received circulated air so as to supply at least one of the received outside air and the received circulated air at a desired temperature to the enclosed environment; circulating the conditioned air into and from the enclosed environment; scrubbing at least some of the received circulated air from the enclosed environment to reduce presence of at least one substance in the circulated air by flowing the at least some of the received circulated air over at least one adsorbent, wherein a concentration of the at least one substance is reduced by adsorption of the at least one substance onto the adsorbent; recirculating the scrubbed air; and exhausting at least a portion of the circulated air from the enclosed environment. - View Dependent Claims (17, 18, 19)

20. A system for circulating air in an enclosed environment, comprising:
-
an inlet configured to receive air from outside of the enclosed environment; 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 is 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 is further configured to generate air for supplying to the enclosed environment; 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; 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, wherein the scrubbing system includes a purge cycle during which a purge substance is applied to the scrubbing system to release the at least one substance from the scrubbing system, and wherein the purge substance includes a gas. - View Dependent Claims (21, 22, 23)

24. A system for circulating air in an enclosed environment, comprising:
-
an inlet configured to receive air from outside of the enclosed environment; 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 is 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 is further configured to generate air for supplying to the enclosed environment; 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; 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; an oxygen injection system that injects oxygen or an oxygen-concentrated air into the circulated air; a control system coupled to at least one sensor disposed in the enclosed environment, wherein; the at least one sensor is configured to determine an oxygen level in the circulated air and provide the determination of the oxygen level in the circulated air to the control system, based on the determination of the oxygen level in the circulated air, the control system is configured to control the oxygen injection system so as to maintain a desired level of oxygen in the circulated air, and the oxygen injection system comprises at least one of the following;
a pressure swing adsorption and a vacuum swing adsorption system. - View Dependent Claims (25, 26)
