Abstract
Abstract A heating system that allows independent control of the temperatures within different rooms in a building by independently controlling the flow of heating fluid to each room in response to a thermostat provided in each individual room. The output of the thermostat controls the operation of a three-way valve upstream of a radiator or convector in each room. When the room temperature is at or above the setpoint for that room, the valve operates to divert all heating fluid flow through a bypass pipe or shunt extending from the valve to the outlet of the radiator or convector. When the temperature drops below the setpoint, the valve operates to resume heating fluid flow through the radiator or convector while shutting off heating fluid flow through the bypass pipe. In another embodiment, independent control of room temperature in heated air distribution systems, is effected by thermostatically controlled louvers provided at the heated air register in each room. When the room temperature is at or above the setpoint for the particular room, the louvers shut off heated air flow to the room thereby preventing further heating of the room.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
327 words
A climate control system for independently controlling the temperature in a plurality of rooms within a building, said climate control system comprising: a source of heating/cooling fluid; a plurality of ducts, each communicating with said source of heating/cooling fluid and having an opening extending to each of the plurality of rooms; a plurality of registers, each provided at said opening of a respective one of said plurality of ducts; a plurality of sets of louvers, each set of said plurality of sets of louvers provided at a respective one of said plurality of registers, each set of said plurality of sets of louvers being movable between a closed position blocking heating/cooling fluid flow through said respective one of said plurality of registers and an open position allowing heating/cooling fluid flow through said respective one of said plurality of registers; a plurality of electromechanical actuating mechanisms, each of said plurality of electromechanical actuating mechanisms being mechanically linked to a respective set of said plurality of sets of louvers to move said respective set of said plurality of sets of louvers between said open position and said closed position; and a plurality of thermostats, each located within a respective one of the plurality of rooms and connected to a respective one of said plurality of electromechanical actuating mechanisms, said respective one of said plurality of electromechanical actuating mechanisms moving said respective set of said plurality of sets of louvers responsive to a respective one of said plurality of thermostats; whereby each of said plurality of electromechanical actuating mechanisms responsive to a respective one of said plurality of thermostats causes a respective one set of said plurality of sets of louvers to be moved to said closed position when air temperature in the one of the plurality of rooms housing said each one of said plurality of thermostats is above a user selected setpoint temperature during a heating cycle, and below a user selected setpoint temperature during a cooling cycle.
Claim 2
Dependent Claim
327 words
A climate control system for independently controlling the temperature in a plurality of rooms within a building, said climate control system comprising: a source of heating/cooling fluid; a plurality of ducts, each communicating with said source of heating/cooling fluid and having an opening extending to each of the plurality of rooms; a plurality of registers, each provided at said opening of a respective one of said plurality of ducts; a plurality of sets of louvers, each set of said plurality of sets of louvers provided at a respective one of said plurality of registers, each set of said plurality of sets of louvers being movable between a closed position blocking heating/cooling fluid flow through said respective one of said plurality of registers and an open position allowing heating/cooling fluid flow through said respective one of said plurality of registers; a plurality of electromechanical actuating mechanisms, each of said plurality of electromechanical actuating mechanisms being mechanically linked to a respective set of said plurality of sets of louvers to move said respective set of said plurality of sets of louvers between said open position and said closed position; and a plurality of thermostats, each located within a respective one of the plurality of rooms and connected to a respective one of said plurality of electromechanical actuating mechanisms, said respective one of said plurality of electromechanical actuating mechanisms moving said respective set of said plurality of sets of louvers responsive to a respective one of said plurality of thermostats; whereby each of said plurality of electromechanical actuating mechanisms responsive to a respective one of said plurality of thermostats causes a respective one set of said plurality of sets of louvers to be moved to said closed position when air temperature in the one of the plurality of rooms housing said each one of said plurality of thermostats is above a user selected setpoint temperature during a heating cycle, and below a user selected setpoint temperature during a cooling cycle.
