Abstract
Embodiments of the invention are directed to a solar-powered ventilation system for mounting to a building. Through the use of internal dampers and destratification intake doors, the system is able to cool the inside of buildings by way of hot-air venting or cold-air induction methods. Further, the system may also be configured in a combinatory manner, allowing the building to be cooled by the simultaneous use of hot-air venting and cold-air induction methods.
Claims16
A self-contained solar-powered ventilation appliance for mounting on a base coupled to a building, the appliance comprising:
- a plenum located outside of the building and coupled to the base;
- a base extension coupled to the base and structured to pass through an opening in a roof of the building and into a confined space of the building, the confined space being below the roof of the building, the plenum and the base extension together creating an air path through the plenum and the base extension;
- a solar panel structured to convert solar energy to electrical power for use by the ventilation appliance;
- a fan motor structured to use the electrical power generated by the solar panel to operate a fan to move air through the air path;
- a set of controllable dampers structured to prevent or allow air from flowing through the air path;
- and
- at least one destratification unit disposed between the fan and the set of controllable dampers, the destratification unit including a destratification door that opens into the confined space and structured to controllably allow building air from within the confined space to enter the base extension through the destratification door and to exit the base extension back into the confined space through an opening other than the destratification door or to exit the base extension through the destratification door and to enter the base extension back into the confined space through an opening other than the destratification door, wherein the plenum, the base extension, the at least one destratification unit, and the solar panel are mechanically coupled and self-contained.

- a fan motor structured to use the electrical power generated by the solar panel to operate a fan to move air through the air path;
- a set of controllable dampers structured to prevent or allow air from flowing through the air path;
- at least one destratification unit disposed between the fan and the set of controllable dampers, the destratification unit including a destratification door that opens into the confined space and structured to controllably allow building air from within the confined space to enter the base extension through the destratification door and to exit the base extension back into the confined space through an opening other than the destratification door or to exit the base extension through the destratification door and to enter the base extension back into the confined space through an opening other than the destratification door;
- a control processor structured to control operation of the ventilation appliance, the control processor including a ventilator interface structured to receive information from at least one other ventilator;
- and
- in which the control processor from a first ventilator interface is structured to control operation of the at least one other ventilator wherein the plenum, the base extension, the at least one destratification unit, and the solar panel are mechanically coupled and self-contained.

A self-contained solar-powered ventilation appliance for mounting to a building, the appliance comprising:
- a solar panel structured to convert solar energy to electrical power for use by the ventilation appliance;
- an air path having a first end terminating outside a confined space of the building, and having a second end terminating within the confined space of the building, the confined space being below an inside ceiling of the building;
- a fan motor structured to use electrical power generated by the solar panel and to operate a fan disposed adjacent to the second end to move air through the air path;
- at least one damper structured to prevent or allow air from flowing through the air path;
- and
- a destratification portion disposed between the fan and the at least one damper, the destratification portion including:
- one or more destratification doors that, when in a closed position, prevent air from flowing into the air path, and, when in an open position, allow air to flow from within the building into the air path, and
- a door controller coupled to the one or more destratification doors and structured to control a position of the one or more destratification doors wherein the air path, the destratification portion, and the solar panel are mechanically coupled and self-contained.
