Systems and methods for supplying fresh outdoor air into a building structure

Abstract

A method and system for supplying fresh outdoor air into a building structure is disclosed. The method includes monitoring indoor and outdoor temperatures and selectively injecting fresh outside air into a supply line based upon the monitoring. Embodiments include injecting the fresh air using an injection duct within the supply line downstream of a forced air device.

1 . An indoor climate control device, comprising:
 one or more processors;   memory; and   one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:   monitoring indoor and outdoor temperatures; and   selectively injecting fresh outside air into a supply line based upon the monitoring.   
     
     
         2 . The indoor climate control device of  claim 1 , further comprising:
 receiving an operating state status of a fan within a ducting apparatus configured for gaseous communication between an exterior vent and the supply line.   
     
     
         3 . The indoor climate control device of  claim 1 , wherein the injecting is at an injection duct within the supply line downstream of a forced air device. 
     
     
         4 . The indoor climate control device of  claim 1 , wherein injecting fresh outside air into a supply line based upon the monitoring is executed by transmitting a command to a fan in gaseous communication between an exterior vent and the supply line. 
     
     
         5 . The indoor climate control device of  claim 1 , wherein selectively injecting fresh outside air into a supply line based upon the monitoring is executed using an injection duct having a circular cross-sectional shape. 
     
     
         6 . The indoor climate control device of  claim 1 , wherein the injection duct is centrally disposed within the supply line via one or more mechanical element. 
     
     
         7 . The indoor climate control device of  claim 1 , wherein the injection duct is disposed within the supply line on a bottom wall thereof. 
     
     
         8 . The indoor climate control device of  claim 1 , wherein the injection duct is substantially parallel to the supply line. 
     
     
         9 . The indoor climate control device of  claim 1 , wherein the injection duct is substantially parallel to the supply line, encased within the supply line, centrally disposed within the supply line, and terminates downstream of a forced air device within the supply line, which has a length greater than the injection duct,
 wherein injecting fresh outside air into a supply line based upon the monitoring is executed by transmitting a command to a fan in gaseous communication between an exterior vent and the supply line, and   wherein selectively injecting fresh outside air into a supply line based upon the monitoring is executed using an injection duct having a circular cross-sectional shape and is centrally disposed within the supply line via one or more mechanical elements.   
     
     
         10 . An indoor climate control system having a supply line, comprising:
 an exterior vent; and   a duct run connected to the exterior vent and terminating within the supply line.   
     
     
         11 . The indoor climate control system of  claim 10 , further comprising:
 a fan configured to selectively draw in outside air.   
     
     
         12 . The indoor climate control system of  claim 10 , further comprising:
 a damper within the duct run proximate to the exterior vent.   
     
     
         13 . The indoor climate control system of  claim 10 , wherein the duct run is disposed through a supply-plenum to the supply line. 
     
     
         14 . The indoor climate control system of  claim 10 , wherein the duct run has an end in a circular cross-sectional shape. 
     
     
         15 . The indoor climate control system of  claim 10 , wherein the duct run is centrally disposed within the supply line via one or more mechanical elements. 
     
     
         16 . The indoor climate control system of  claim 10 , wherein the duct run is disposed within the supply line on a bottom wall thereof. 
     
     
         17 . The indoor climate control system of  claim 11 , wherein the fan is configured to inject fresh air into the supply line at a flow rate to cause a vortex effect within the supply line. 
     
     
         18 . An indoor climate control system for a forced air system having a return line and a trunk supply line, the system comprising:
 an exterior vent configured to drawn in fresh outside air;   a fan; and   a duct run connected to the exterior vent and terminating within the supply line, wherein the fan is disposed within the duct run in gaseous communication with the exterior vent and configured to inject fresh air into the supply line, wherein a portion of the duct run is parallel with sidewalls of the supply line.   
     
     
         19 . The indoor climate control system of  claim 18 , wherein the duct run is centrally disposed within the truck supply line via one or more mechanical elements, and wherein the duct run has an end in a circular cross-sectional shape. 
     
     
         20 . The indoor climate control system of  claim 18 , wherein the duct run is disposed through a supply-plenum to the supply line, and wherein the system further comprises a damper within the duct run proximate to the exterior vent.
