Problems solved by technology

[0009] Although lead-lag controllers overcome some of the disadvantages of simple redundant implementations, they are often not able to optimize cooling system energy efficiency nor fully optimize cooling system overall life
The failure of the lead-lag controller itself may in some cases lead to the failure of the entire cooling system, weakening the immunity of the single failure of the redundant system

Abstract

A redundant cooling method and system are provided. The method comprises: providing a plurality of variable refrigerant flow air cooling units, wherein the number of air cooling units is at least one more than required to meet a selected maximum cooling load when operating the air cooling units at up to a maximum cooling capacity; coupling the plurality of variable refrigerant flow air cooling units in thermal communication with the air in a conditioned space; determining a select optimum operating condition for each of the plurality of variable refrigerant flow air cooling units which will result in about a lowest overall energy consumption for the redundant cooling system, while maintaining an average temperature of the air in the conditioned space at a required setpoint; and operating said plurality of air cooling units in about the select optimum operating conditions for each of the air cooling units.

Description

technical field [0001] Embodiments disclosed herein relate generally to air handling and cooling systems. More particularly, the embodiments relate to apparatus and methods for redundant cooling systems for electronic equipment. Background technique [0002] A known method for cooling or reducing excess heat from heat generating electronic equipment during operation is to provide air conditioners or other air cooling systems adjacent to the various electronic components. If a reliable cooling system is not employed, electronic components may be damaged by excessive heat build-up, or operation may be interrupted by internal protection mechanisms designed to provide protection against excessive temperatures, either of which is critical for critical applications. Unwanted. [0003] Currently, critical electronic and electrical related applications necessarily employ redundant air cooling systems whereby there are at least two air cooling units in an N+1 configuration. At lea...
