Patent ID: 7937895

Claim:
A thermally broken air handling chamber comprising: a weight bearing exterior base having a pair of spaced apart exterior base side members and a plurality of spaced apart exterior base cross members extending transversely between said exterior base side members, said exterior base presenting a lower, grounding plane of said air handling chamber; a weight bearing interior base having a pair of spaced apart interior base side members, a plurality of spaced apart interior base cross members having a lower portion and an upper portion, said interior base cross members extending transversely between said interior base side members, and a floor plate in contact with said upper portion of said interior base cross members, said interior base supported by said exterior base with each of said plurality of exterior base cross members being aligned with a respective one of said plurality of interior base cross members in load bearing relationship, said floor plate oriented in spaced apart relationship from said grounding plane; a structural load bearing thermal insulation material disposed interstitially between said lower portions of respective aligned ones of said interior base cross members and said exterior base cross members, such that said interior base is supported by said exterior base cross members in load bearing, thermally isolated relationship; a second thermal insulation material disposed between said floor plate and said grounding plane; an interior shell supported in load bearing relationship by said interior base said interior shell and said interior base cooperating to define an interior chamber; an exterior shell supported in load bearing relationship by said exterior base said exterior shell being spaced apart from and substantially surrounding said interior shell, said air handling chamber being clear of structural load bearing coupling that bridges said exterior base and said interior base other than through said load bearing, thermally isolated relationship of said interior base and said exterior base cross members.
