1. A venting system for attachment to an enclosure configured for housing heat generating components, the enclosure having a primary air conditioner, the venting system comprising:
a vent housing comprising:
a warm air conduit formed in a top area by a roof (110) and a stepped element (111) that includes a shelf, the shelf being interior to a first opening and cover (106) of the warm air conduit configured for warm air exhaust from the enclosure, the warm air conduit comprising a fan (103), the fan having an unimpeded flow access to, and being configured to expel warm air from the enclosure via, a first damper (104a) disposed atop the shelf and offset from the first opening, the first damper oriented vertically and comprising first blades that are biased closed and configured to be opened by operation of the fan to permit warm air exhaust from the enclosure and out of the first opening; and
a lower area comprising a cool air inlet and second damper (104b) having blades biased closed, wherein the blades of the second damper are configured to be opened by operation of the fan creating negative pressure in the enclosure, the second damper being oriented tangentially to the first damper and separated from the first damper by the stepped element, the second damper permitting flow of cooling air into the enclosure;
wherein the fan is configured to, under operation with alternating current power lost and loss of the operation of the primary air conditioner, operate to create a negative pressure in the enclosure, passively opening the blades of the second damper and permitting the flow of cooling inward through the second damper.
