An exterior wall port apparatus to support a vent hose of a portable air conditioning unit, said apparatus comprising:
- an exterior port fitting having a cylindrical hollow shape having a first end, a second end, an inside surface area, and an outside surface area, said first end having an outermost edge and a top side,
- wherein said first end comprises at least one twist lock protrusion at said outermost edge and a water groove that traverses said top side and terminates at opposing lower points of said first end;
- an interior port fitting having a cylindrical hollow shape coinciding in size to tightly fit inside said exterior port fitting, said interior port fitting having a first end, a second end, an inside surface area, and an outside surface area,
- wherein said first end of said interior port fitting is coupled to said second end of said exterior port fitting,
- wherein said second end of said interior port fitting comprises a first stabilizing flange and wherein said second end of interior port further comprises at least one twist lock groove and a set of ratcheting teeth, both disposed on said inner surface area;
- an interior hose adapter having a cylindrical hollow shape coinciding in size to tightly fit inside said interior port fitting, said interior hose adapter having a first end, a second end, an inside surface area, and an outside surface area,
- wherein said first end of said interior hose adapter is configured at the outside surface area to comprise at least one twist lock protrusion and a set of ratcheting tabs, said interior hose adapter further comprising a second stabilizing flange centrally disposed about said outer surface area;
- wherein said first end of said interior hose adapter slides into said second end of said interior port fitting such that said at least one twist lock protrusion and said set of ratcheting tabs of said interior hose adapter interlock with said at least one twist lock groove and said set of ratcheting teeth of said interior port fitting;
- and
- wherein said first end of said exterior port fitting is coupled to either a louvered cover plate or an exterior vent cap;
- said louvered cover plate having a frontside and a backside,
- wherein said frontside comprises multiple downward-positioned horizontal louvers, and
- wherein said backside comprises a circular area coinciding in size with said cylindrical hollow shape of said exterior port fitting, said circular area comprising a circular interior ridge having at least one twist lock groove and a mesh grating covering said circular area;
- said exterior vent cap comprising:
- an exterior port flange having a larger diameter than said exterior port fitting,
- an integral downward-curved rain hood at an outer top portion of said exterior port flange,
- an integral downward-sloped drip guard at an outer bottom portion of said exterior port flange, with a weep hole above said drip guard,
- two hinges opposingly disposed near an upper portion of said exterior port flange,
- a centrally disposed vent flap with a circular opening coinciding with said cylindrical hollow shape of said exterior port fitting, said two hinges pivotally coupled to said vent flap,
- a damper disposed around said circular opening of said vent flap, and
- a backside with an integral circular ridge with at least one twist lock groove;
- and
- wherein said first end of said exterior port fitting is inserted into either said backside of said louvered plate cover or said backside of said exterior vent cap, such that at least one twist lock protrusion of said exterior port fitting interlocks with either said at least one twist lock groove of said louvered cover plate or said at least one twist lock groove of said exterior vent cap.
