Method and apparatus for controlling air flow in a structure

摘要

Flow control valves (19) are provided and interfaced with the HVAC ducts (14) at the efferent ends (16) in adjoining rooms of a structure. A flow control command device (29), mounted on the wall of the structure (25), is provided to control the flow of air through the HVAC ducts (14) in response to flow control commands. Flow control commands are transmitted by wireless means to the command decoder (22) and converted to flow control signals. A flow control signal bus (21) is provided to connect the flow control signals to the flow control valves (19). A master thermostat (32) is connected directly to the HVAC system (10) and in series with a slave thermostat (30). This series thermostat connection causes control of the HVAC system (10) to be determined by the thermostat located in the room that receives the higher air flow.
