Redundant Cooling Method and System
First Claim
1. A method of implementing a redundant cooling system comprising:
- 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 at about the select optimum operating conditions for each of the air cooling units.
