Systems and methods for controlling and adjusting volume of fresh air intake in a building structure
Patent number: 11802698Abstract: A fresh-air cooling system and methods of cooling a building structure with the same are provided. The system has an exterior interface assembly, a damper, a register, a duct, and a motorized fan. The exterior interface assembly is connected to the register by the duct and provides a flow path for air outside the building to enter the duct. The motorized fan is disposed in an attic of the building structure and pulls air into the attic from a living space to create a negative static pressure in the living space. The damper is positioned along the flow path from the exterior interface assembly to the living space and opens to allow air outside the building structure to enter the living space in response to motorized fan creating in the living space a negative static pressure that exceeds the cracking pressure of the damper. The cracking pressure of the damper can be adjusted to control the flow rate of outside air through the damper.Type: GrantFiled: March 11, 2022Date of Patent: October 31, 2023Assignee: QC MANUFACTURING, INC.Inventor: Dana Charles Stevenson -
