  • Patent number: 11821651
    Abstract: 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.

  • Patent number: 11802698
    Abstract: 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.

  • Patent number: 11781762
    Abstract: 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.

  • Patent number: 11609015
    Abstract: A multifunction adaptive whole house fan system can include a whole house fan to pull large volume of air through a building structure. The whole house fan can pull air from a motorized window or damper into the building structure and expel air through an attic. The system can monitor the environment to operate the whole house fan when desired conditions are present in coordination with other systems of the building structure to reduce overall energy consumption.

  • Patent number: 11460204
    Abstract: An automated cooling system and method for energy efficient use with a building structure by adjusting operational parameters is provided. The automated cooling system can adjust operational parameters in response to conditions (e.g., temperature, humidity) detected by sensors located at one or more strategically selected locations inside or outside the building structure. The automated cooling system can ramp speeds of a motor that rotates fan blades in response to changes in the air temperature in the building structure so as to maintain a desired temperature without switching on and off the motor to preserve fan blade inertia.

  • Patent number: 7497774
    Abstract: A whole house fan system and installation methods configured to reduce noise generated by the fan are provided. The system generally includes a fan, a register, and a flexible duct extending between the fan and the register. The flexible duct has acoustical insulation properties, which helps to reduce sound transmission from the fan to the register. The fan system is configured to be mounted in the attic space of a house. The fan motor is suspended in the attic so that it does not have direct contact with any part of the building structure.
