ABSTRACT:
An airhouse for supplying conditioned air to the interior of an enclosed building. Matched twin blowers symmetrically arranged within the airhouse enclosure are operated in unison to insure a balanced air flow into the airhouse and through the blowers. A burner unit mounted intermediate the blowers is flanked by matching outside air inlets having controllable dampers, preferably of a canister-type, operable in opposition. A building return air inlet located midway between the blowers likewise has canister-type dampers operable in opposition. The blowers may be independent and operated at the same speed by separate drive means, or they may be mounted on a common shaft operated by a single drive means. A controller may be provided for varying the speed of the drive means. In one embodiment dampers may be provided for the building air outlets along with dampered openings from the blower enclosures to the external atmosphere for rapidly expelling contaminated air from the building interior.
