The disclosure provides an improved cooling system and associated cabinet for electronic equipment, and optionally, a backup ventilation system for cooling related failures. Generally, the disclosure includes a high capacity closed loop refrigeration system in a modified cabinet, while accommodating standard sized computer equipment. Further, the system provides directed heat removal by altering typical airflow paths within the cabinet. The backup ventilation system is powered by auxiliary power in the case of power failure and uses the same fan(s) for ventilation as is used for cooling. The disclosure provides a more efficient, higher capacity cooling cabinet in less space than otherwise known in the art. Further, the cooling system can anticipate heat loads and therefore operate in a predictive capacity by monitoring input power to the electronic equipment and adjusting the cooling for the expected increase or decrease in heat load generated based on the input power.

What is claimed is: 1. An electronic equipment cabinet, comprising: a cabinet configured to operatively house a plurality of electronic equipment, at least a portion of a primary cooling system and a backup cooling system, the cabinet securable against unwanted access to the electronic equipment; the primary cooling system comprising: a compressor; an evaporator within the cabinet; at least one fan within the cabinet for moving air along a primary cooling flow path through the evaporator and across the electronic equipment; a condenser; and a refrigerant, all operatively coupled in closed-loop fashion and configured to reject heat from within the cabinet to outside the cabinet; the backup cooling system comprising: at least one backup cooling damper associated with the cabinet and configured to seal against ambient air flow there through during operation of the primary cooling system and to automatically open upon a cooling related failure in the primary cooling system; and a control system configured to, upon the cooling related failure, open the damper and energize the at least one evaporator fan thereby drawing ambient air from outside the cabinet through the damper and into the cabinet along a backup cooling path to cool the electronic components; wherein the backup cooling damper closes off the evaporator so that the backup cooling air flow path within the cabinet comprises flowing air across the electronic components but not through the evaporator. 2. The cabinet of claim 1, wherein the control system is configured to control one or more operational factors selected from the group consisting of: operation of the compressor; operation of the at least one fan; operation of a condenser valve; and operation of the damper. 3. The cabinet of claim 1, wherein the backup cooling system further comprises: a power supply operatively coupled to the fan and the control system, and configured to provide power to the fan upon the cooling related failure. 4. The cabinet of claim 3, wherein the power supply is an uninterruptible power supply. 5. The cabinet of claim 1, wherein the cooling related failure comprises a failure of a primary cooling system component. 6. The cabinet of claim 1, wherein the cooling related failure comprises an electrical power failure. 7. The cabinet of claim 1, wherein the control system is configured to establish the backup cooling air flow path on the cooling related failure. 8. The cabinet of claim 7, wherein the fan is configured to move air through the second air flow path when the damper is open. 9. The cabinet of claim 1, wherein the compressor is located at least partially within the primary cooling air flow path. 10. The cabinet of claim 1, wherein the electrical equipment comprise standard-sized computer equipment. 11. The cabinet of claim 1, further comprising: an exhaust fan configured to flow air heated by the electrical equipment across the condenser. 12. The cabinet of claim 11, wherein the control system energizes the exhaust fan on the cooling related failure. 13. The cabinet of claim 1, wherein the condenser is not within the cabinet. 14. The cabinet of claim 1, wherein the cabinet includes a first portion housing the electronic equipment and a second portion housing the condenser, such that the condenser is not within the portion of the cabinet housing the electronic equipment. 15. The cabinet of claim 1, wherein the cabinet includes a first portion housing the electronic equipment, a second portion housing the compressor and the evaporator, and a third portion housing the condenser. 16. The cabinet of claim 15, wherein the portions are divided by partitions. 17. The cabinet of claim 15, wherein the at least one fan of the primary cooling system includes a plurality of vertically spaced fans configured to establish the primary cooling flow path between the first portion and the second portion. 18. The cabinet of claim 17, wherein the primary cooling flow path is substantially horizontal throughout both the first and second portions. 19. The cabinet of claim 17, the cabinet further including an exhaust fan to establish a secondary air flow path through the condenser, the secondary air flow path being separate from the primary cooling flow path.
