Abstract
Systems and methods for air flow circulation are described which utilize one or more air conditioning units as well as transfer grilles to move cooler air from one space to another. The transfer grilles can include bi-directional in-line fans to move air between spaces in discrete ducts located between the spaces. Motorized dampers can be controlled by a controller that receives information about various rooms and areas from temperature and occupancy sensors within those rooms or areas. In this manner, conditioned air can be directed to those rooms that are occupied and whose temperature needs correction based on a thermostat setting, and use of the air conditioning unit can be avoided when a cool air source is present in another space.
Claims12
A method of circulating airflow within a structure having first, second, and third spaces, and in operative communication with an air conditioning unit configured to supply cool air to each of the first, second, and third spaces via a duct that connects the air conditioning unit with each of a first outlet at the first space, a second outlet at the second space, and a third outlet at the third space, the first and second spaces being connected by a first transfer grille, and the second and third spaces being connected by a second transfer grille, the method comprising:
- receiving temperature information from first, second, and third temperature sensors, each being disposed in the first, second, and third spaces, respectively;
- sending a first signal to a first fan disposed within the first transfer grille to modulate an airflow between the first and second spaces;
- and
- sending a second signal to a second fan disposed within the second transfer grille to module an airflow between the second and third spaces, such that air moves from the first space to the second space and then to the third space, the first and second signals being based on a different in temperature between the first and third rooms.
A method of circulating airflow within a structure having a plurality of spaces and in operative communication with an air conditioning unit configured to supply cool air to each of the plurality of spaces, adjacent ones of the plurality of spaces being connected by a respective transfer grille, the system comprising:
- receiving, at a controller, temperature information from first, second, and third temperature sensors and a signal from a thermostat, the first, second, and third temperature sensors being configured to detect temperatures in first, second, and third rooms, respectively;
- sending a signal from the controller to a first inline fan to modulate an airflow between the first and second rooms;
- and
- sending a signal from the controller to a second inline fan to modulate an airflow between the second room and a third room, such that air moves from the first room to the second room and then to the third room, wherein the signals sent to the first and second inline fans are based on the signal received from the thermostat and a difference in temperature between the first and third rooms.
