Novel air regulation device and air conditioning system

A multiple zone climate control system, comprising

• a. a HVAC unit that supplies conditioned air to more than one zone;
• wherein the HVAC unit contains a heating unit or a cooling unit or combination thereof.
• b. a zone controller in the zone requiring climate control;
• c. a central controller, said central controller controls said HVAC unit to be in a state selected from heating, cooling, ventilating, and off;
• wherein the central controller turns off the heating or cooling unit after all zones or selected zones reach their preset conditions respectively and turns on the heating or cooling unit after a predefined number of zone's preset condition is not met.
• d. one or more air flow rate regulating devices in each zone requiring climate control, wherein each said air flow rate regulating devices is powered and is built into a register or placed on top of the register, each said air flow rate regulating device comprises one or more dampers or boosters or combination thereof and an air flow rate regulating device controller, wherein said air flow rate regulating device controller can communicate with said zone controller or central controller and adjust the degree of openness of said damper accordingly or adjust the performance of said booster accordingly to reach a desired climate control which is set at the zone controller in each zone;
• and
• e. a digital wireless network that connects said central controller, said zone controllers and said air flow rate regulating devices, wherein said zone controllers communicate with the central controller through said digital wireless network.
