An electronic equipment enclosure for outdoor deployment includes a housing defining an interior and having an intake port, an exhaust port, an airflow path extending from the intake port to the exhaust port, and an equipment bay for receiving the electronic equipment. The equipment bay is positioned in the airflow path. The equipment enclosure further includes an intake fan for creating positive pressure within the interior of the housing and a pressure-activated damper having an open position for allowing air to exit the enclosure through the exhaust port in response to positive pressure within the interior of the housing and a closed position for preventing external air and/or water from entering the enclosure through the exhaust port when the intake fan is not operating. Other example equipment enclosures and methods are also disclosed.

1. An outdoor electronic equipment enclosure, comprising: a housing defining an interior and having an intake port, an exhaust port, and an airflow path extending from the intake port to the exhaust port;at least one fan for moving air through the airflow path extending from the intake port to the exhaust port;a first sensor for measuring an air temperature external to the enclosure;a second sensor for measuring an air temperature within the interior of the housing; anda controller operatively coupled to the fan, the first sensor and the second sensor, the controller configured to selectively operate the fan to maintain a defined temperature differential between the air temperature external to the enclosure and the air temperature within the interior of the housing to thereby inhibit condensation within the interior of the housing. 2. The outdoor enclosure of claim 1 wherein the defined temperature differential is a fixed temperature differential. 3. The outdoor enclosure of claim 2 wherein the defined temperature differential is approximately five degrees Celsius. 4. The outdoor enclosure of claim 2 wherein the outdoor enclosure does not include an air conditioner. 5. The outdoor enclosure of claim 4 wherein the housing includes a door having an opening extending therethrough, wherein the airflow path passes through the door opening, and wherein the fan is mounted to the door over the door opening. 6. The outdoor enclosure of claim 5 further comprising a pressure-activated damper having an open position for allowing air to exit the outdoor enclosure through the exhaust port in response to positive pressure within the interior of the housing and a closed position for preventing external air and/or water from entering the enclosure through the exhaust port when the intake fan is not operating. 7. The outdoor enclosure of claim 2 wherein the equipment enclosure is deployed in an outdoor environment and includes at least one item of outside plant equipment positioned within the housing interior. 8. The outdoor enclosure of claim 2 further comprising a filter positioned in the airflow path between the intake port and the at least one fan. 9. The outdoor enclosure of claim 8 wherein the filter includes a particle filter. 10. The outdoor enclosure of claim 8 wherein the filter includes a hydrophobic filter. 11. The outdoor enclosure of claim 10 wherein the filter further includes a particle filter positioned in the airflow path upstream of the hydrophobic filter. 12. The equipment enclosure of claim 10 wherein there is no hydrophobic filter associated with the exhaust port. 13. The outdoor enclosure of claim 2 wherein there is no exhaust fan associated with the exhaust port. 14. The outdoor enclosure of claim 2 wherein the housing includes a door having an opening extending therethrough, wherein the airflow path passes through the door opening, and wherein the fan is mounted to the door over the door opening. 15. The outdoor enclosure of claim 2 further comprising a pressure-activated damper having an open position for allowing air to exit the outdoor enclosure through the exhaust port in response to positive pressure within the interior of the housing and a closed position for preventing external air and/or water from entering the enclosure through the exhaust port when the intake fan is not operating. 16. The outdoor enclosure of claim 1 further comprising a heater, wherein the controller is configured to selectively operate the heater to maintain the defined temperature differential.
