Abstract

A heating, ventilation, and air conditioning (HVAC) system comprises a housing defining a chamber configured to receive a first air flow and a second air flow. The chamber comprises a vacant section and a heating section, and the heating section comprises a heating coil. A first blower is configured to direct the first air flow into the vacant section of the chamber and a second blower is configured to direct the second air flow into the heating section of the chamber. The housing is configured to direct the first air flow from the vacant section to the heating section to combine with the second air flow and configured to direct the first air flow and the second air flow across the heating coil.

         10 . The HVAC system of  claim 9 , comprising the first blower and the second blower, wherein the first blower is configured to direct a first air flow along a first air flow path through the chamber to the discharge outlet of the housing, and the second blower is configured to direct a second air flow along the second air flow path to the discharge outlet of the housing. 
     
     
         11 . The HVAC system of  claim 10 , wherein the housing comprises a first inlet configured to receive the first air flow from the first blower into the open section and a second inlet configured to receive the second air flow from the second blower into the heating section of the chamber. 
     
     
         12 . The HVAC system of  claim 10 , wherein the discharge outlet is formed within a lateral side of the housing. 
     
     
         13 . The HVAC system of  claim 9 , comprising a baffle disposed within the chamber and configured to deflect air flow traveling along the first air flow path, the second air flow path, or both, toward the heating coil. 
     
     
         14 . The HVAC system of  claim 9 , wherein the heating coil is disposed at an oblique angle relative to a direction of air flow through the chamber toward the discharge outlet. 
     
     
         15 . A heating system of a heating, ventilation, and air conditioning (HVAC) system, comprising:
 a housing defining a chamber comprising a vacant section and a heating section, wherein the housing comprises a first inlet configured to direct a first air flow into the vacant section and a second inlet configured to direct a second air flow into the heating section; and   a heating coil disposed within the heating section, wherein the housing is configured to direct the first air flow from the vacant section to the heating section to combine the first air flow with the second air flow and configured to direct the first air flow and the second air flow across the heating coil.   
     
     
         16 . The heating system of  claim 15 , comprising:
 a first blower configured to direct the first air flow along a first air flow path extending from the first blower, through the first inlet, through the vacant section, through the heating section, and across the heating coil; and   a second blower configured to direct the second air flow along a second air flow path extending from the second blower, through the second inlet, through the heating section, and across the heating coil.
