Patent ID: 8327656

Claim:
A method of controlling a plurality of cooling units within a data center, the method comprising: operating the plurality of cooling units within the data center, wherein each cooling unit includes a controller unit that communicates with the plurality of cooling units over a network; calculating sensible cooling capacity of each cooling unit during operation of the cooling unit, wherein the calculating is conducted by the controller unit in each cooling unit; displaying the calculated sensible cooling capacity of each cooling unit on a display positioned within the data center; and manipulating at least one cooling unit of the plurality of cooling units to control a temperature of the data center based at least in part on the calculated sensible cooling capacity of each cooling unit, wherein the manipulating is conducted by the controller unit in the at least one cooling unit and includes reducing the cooling capacity of one of the plurality of cooling units by bypassing hot gas back to an evaporator of the cooling unit and manipulating an evaporator fan of the cooling unit; and wherein the controller unit in each cooling unit includes firmware comprising a program control loop.
