Claim of US Patent No. 9,326,426

1. An equipment enclosure, comprising:
an air exhaust opening disposed at a first region of said equipment enclosure;
an air intake opening disposed at a second region of said equipment enclosure;
an interior equipment chamber configured to house controlled temperature equipment at a controlled temperature equipment area
therein;

a temperature diverter system, said air diverter system comprising:
a warm air exhaust subsystem operable to vent warm air collected at a top of said equipment enclosure through said air exhaust
opening in order to cool said controlled temperature equipment area; and

a warm air circulation subsystem operable to circulate warm air collected at said top of said equipment enclosure to said
controlled temperature equipment area in order to warm said controlled temperature equipment area;

said temperature diverter system comprising either (1) a common air mover that is shared by said warm air exhaust subsystem
and said warm air circulation subsystem, with said warm air exhaust subsystem comprising a first movable damper and said warm
air circulation subsystem comprising a second movable damper, each said damper being mechanically connected to a damper motor
implemented as a multi-position stepper motor that selectively positions said damper through a range of positions so that
said warm air collected at said top of said equipment enclosure is selectively directed by said common air mover to said warm
air exhaust system and said warm air circulation system, or (2) a first air mover for said warm air exhaust subsystem and
a second air mover for said warm air circulation subsystem, said first air mover and said second air mover being controllable
so that said warm air collected at said top of said equipment enclosure is selectively directed by said first air mover and
said second air mover to said warm air exhaust system and said warm air circulation system;

one or more temperature sensors; and
a digital temperature controller implementing a control routine for controlling operations of said warm air exhaust subsystem
and said warm air circulation subsystem based on input from said one or more temperature sensors.
