Abstract
A system for cooling an environment housing a plurality of electronic equipment in one or more cabinets is disclosed, the system comprising a remote cooling unit(s) adapted to provide relatively cool air into the environment, an exhaust associated with each cabinet, the exhaust being provided with variable airflow means; the remote unit being adapted to receive exhausted air, and; sensor means adapted to determine cooling demand and alter the output of the remote cooling unit(s) accordingly. Schemes for using the system are described.
Claims21
A system for cooling an environment housing a plurality of electronic equipment in one or more ICT (Information Communication Technology) equipment cabinets, comprising:
- one or more remote cooling units including a return side and a supply side, the one or more remote cooling units introducing relatively cool air into the environment from the supply side and receive return air at the return side;
- a plurality of active cabinet exhaust products, wherein each associated with a respective ICT equipment cabinet of the one or more ICT equipment cabinets for receiving discharge air from said respective ICT equipment cabinet, each of the plurality of active cabinet exhaust products being provided with temperature sensing means and variable airflow means, wherein the temperature sensing means senses a temperature of the discharge air from each of the one or more ICT equipment cabinets, a temperature of the return air, and a temperature of the relatively cool air;
- airflow determining means for determining discharge airflow from each of the plurality of active cabinet exhaust products;
- combined airflow means for determining a combined airflow from the discharge airflow of all of the plurality of active cabinet exhaust products;
- cooling parameter means for using the combined airflow to determine one or more cooling parameters such that the plurality of active exhaust products optimize the discharge airflow across each of the one or more ICT equipment cabinets while the remote cooling unit operates at a constant temperature differential between the relatively cool air and the return air;
- and
- airflow demand means utilizing the temperatures sensed by the temperature sensing means to determine an airflow demand to be provided by the one or more remote cooling units as the relatively cool air, wherein the one or more remote cooling units receive the return air at a relatively high temperature and vary air volume of the relatively cool air as a means of controlling cooling capacity to maintain the constant temperature differential.
