Patent number: 11821651Abstract: An energy efficient and quiet air cooling system for a building structure is provided. The air cooling system includes an evaporator system mounted in the wall of the building, a remotely mounted fan, an air intake, and a sound and heat insulating duct. The fan is mounted in the attic and configured to draw air from the living area of the building through the sound insulating duct with sufficient power to create a negative static pressure in the living area. The negative static pressure in turn causes outside air to flow through the evaporator system which removes heat from the outside air. The cooled air is in turn drawn into the building and pulled into the attic through the duct and expelled through the attic. The fan expels warm air into the attic, creating a positive pressure environment which causes the warm air to be expelled from the attic through natural vents.Type: GrantFiled: August 24, 2020Date of Patent: November 21, 2023Assignee: QC MANUFACTURING, INC.Inventor: Dana Charles Stevenson

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 -
Patent number: 11781762Abstract: A fresh-air cooling system for a building structure having an unvented attic is provided. The system provides airflow pathways that allow outside air to be drawn through, and discharged from, a building having an unvented attic. Dampers with a low thermal conductivity regulate airflow through the building structure. The system allows a whole house fan to cool a building having an unvented attic. The system seals or otherwise alters airflow pathways through the building structure in order to reduce heat transfer between the building and the outside environment when the cooling system is not in use.Type: GrantFiled: November 9, 2020Date of Patent: October 10, 2023Assignee: QC MANUFACTURING, INC.Inventor: Dana Charles Stevenson
