Systems and method for hvac air flow increase

Abstract

The method may be a process of increasing the size and placement of return air ducts to increase the efficiency and airflow of a heating and cooling system. The process may take into consideration the current placement and sizes of return air in an existing building or may take into consideration the size of new construction for proper size and placement of return air ducts. The process allows for increased surface area which in turn allows for increased air intake and increased output.

What is claimed: 
     
         1 . A method for increasing airflow in an HVAC system comprising:
 selecting a furnace with a preexisting return airflow duct, the furnace located in a first room;   connecting a second return airflow duct to the furnace, the second return airflow duct passing through a wall of the first room and into a second room, the second return airflow duct in communication with a return air inlet grille in the second room.   
     
     
         2 . The method of  claim 1 , further comprising the step of providing the second return airflow duct with a filter. 
     
     
         3 . The method of  claim 2 , further comprising the step of providing the second return airflow duct with a filter rack, and placing the filter in the filter rack. 
     
     
         4 . The method of  claim 1 , wherein the step of selecting a furnace with a preexisting return airflow duct comprises selecting a furnace with a preexisting return airflow duct on a first side of the furnace. 
     
     
         5 . The method of  claim 4 , wherein the step of connecting the second return airflow duct to the furnace comprises connecting the second return airflow duct on a second side of the furnace, the second side of the furnace opposite the first side of the furnace. 
     
     
         6 . The method of  claim 4 , further comprising the step of raising the furnace, and wherein the step of connecting the second return airflow duct to the furnace comprises connecting the second return airflow duct on a bottom side of the furnace. 
     
     
         7 . The method of  claim 6 , further comprising the step of providing a stand to support the bottom side of the furnace. 
     
     
         8 . The method of  claim 1 , wherein the step of connecting a second return airflow duct to the furnace comprises connecting the second return airflow duct to the preexisting return airflow duct. 
     
     
         9 . A process of increasing airflow in an HVAC system comprising:
 measuring current volume in a return air duct;   measuring current space allowable for the return air duct; and   installing a larger volume return air duct.   
     
     
         10 . The process of  claim 9 , wherein the step of installing a larger volume return air duct comprises increasing a volume of a preexisting return air duct. 
     
     
         11 . The process of  claim 9 , wherein the step of installing a larger volume return air duct comprises attaching a second return airflow duct to a furnace. 
     
     
         12 . The process of  claim 11 , wherein the furnace is located in a first room, and wherein the second return airflow duct is in communication with a return air inlet grille located in a second room. 
     
     
         13 . The process of  claim 12 , further comprising the step of attaching a filter to the second return airflow duct. 
     
     
         14 . The process of  claim 11 , wherein the step of attaching a second return airflow duct to the furnace comprises attaching the second return airflow duct on a side of the furnace opposite a side of a preexisting return air duct. 
     
     
         15 . The process of  claim 9 , wherein the step of installing a larger volume return air duct comprises installing a second return airflow duct to a rooftop HVAC unit. 
     
     
         16 . A process of increasing airflow in an HVAC system comprising:
 measuring current volume in a return air duct;   measuring current space allowable for the return air duct;   installing a plurality of return air ducts in a plurality of locations; and   increasing volume of the airflow through the plurality of air ducts.   
     
     
         17 . The process of  claim 16 , wherein the step of installing the plurality of return air ducts in a plurality of locations comprises installing a first return air duct in communication with a first side of a furnace and installing a second return air duct in communication with a second side of the furnace. 
     
     
         18 . The process of  claim 17 , wherein the second side is opposite the first side. 
     
     
         19 . The process of  claim 16 , further comprising the step of installing a filter at each of the plurality of return air ducts. 
     
     
         20 . The process of  claim 16 , wherein the step of installing a plurality of return air ducts comprises installing at least one return air duct to a rooftop HVAC unit.
