         8 . The air-handling apparatus of  claim 1 , further comprising a partition wall within the housing that fluidly separates a low-pressure chamber of the air-handling apparatus from a high-pressure chamber of the air-handling apparatus. 
     
     
         9 . The air-handling apparatus of  claim 8 , wherein the centrifugal fan is mounted on a surface of the partition wall. 
     
     
         10 . The air-handling apparatus of  claim 1 , wherein the air inlet is disposed in a first vertical wall of the housing and the air outlet is disposed in the first vertical wall of the housing. 
     
     
         11 . The air-handling apparatus of  claim 1 , wherein the centrifugal fan comprises a fan inlet that receives the first air and a fan outlet that discharges the second air. 
     
     
         12 . The air-handling apparatus of  claim 1 , wherein the centrifugal fan rotates about an axis, and the first air enters the fan inlet in a third direction that is parallel to the axis. 
     
     
         13 . The air-handling apparatus of  claim 12 , wherein the third direction is perpendicular to the first direction. 
     
     
         14 . The air-handling apparatus of  claim 1 , wherein the air temperature-conditioning component is configured to change a temperature of one of the first air or the second air. 
     
     
         15 . The air-handling apparatus of  claim 14 , wherein the air temperature-conditioning component is configured to change the temperature by at least one of increasing the temperature or decreasing the temperature. 
     
     
         16 . The air-handling apparatus of  claim 1 , further comprising a control cabinet within the housing that includes at least one of a hydronic control device or an electrical control device. 
     
     
         17 . The air-handling apparatus of  claim 1 , further comprising a mixing box that is fluidly coupled to the air-handling apparatus and receives additional conditioned air.
