Abstract
A method for controlling one or more computer room air conditioning (CRAC) units configured to receive return air for energy efficient operation. In the method, the temperature of the air returned (Trat) into the one or more CRAC units is detected. It is determined whether the Trat is within a predetermined setpoint temperature range and at least one operation of the one or more CRAC units is reduced in response to the Trat being within the predetermined setpoint temperature range to thereby increase the efficiencies of the one or more CRAC units.
