A facility-based dual-purpose conditioned air blower system includes a heat exchange unit, a diverter apparatus, and a centrifugal blower. The heat exchange unit includes an ambient air inlet, heat exchange elements, and a conditioned air outlet. The diverter apparatus includes a diverter inlet fluidly coupled to the conditioned air outlet of the heat exchange unit, a first diverter outlet to the facility, and a second diverter outlet. The diverter apparatus is moveable between a first position wherein the first diverter outlet is closed and the second diverter outlet is open, and a second position wherein the first diverter outlet is open and the second diverter outlet is closed. The centrifugal blower includes a blower inlet fluidly coupled to the second diverter outlet of the diverter apparatus, and a blower outlet positioned to ventilate a trailer interior with conditioned air from the conditioned air outlet of the heat exchange unit.

System and method for providing conditioned air at a loading dock

A conditioned air blower system for ventilating a trailer interior includes a centrifugal blower and a heat exchange unit. The centrifugal blower includes a blower housing, an inlet portion configured to direct air into the blower housing, and a discharge portion configured to direct air from the blower housing into the trailer interior. The heat exchange unit includes an air inlet portion, heat exchange elements, and a conditioned air exit portion coupled to the inlet portion of the centrifugal blower. The heat exchange unit conditions ambient air introduced at the air inlet portion from a first temperature to a second temperature by heat exchange relationship with the heat exchange elements. The conditioned air blower system may include a controller operatively associated with the centrifugal blower. The controller monitors a condition related to the centrifugal blower, and regulates the supply of temperature-conditioned air in response to the condition.
