System and method for zone thermostat budgeting

a thermostat and budgeting technology, applied in space heating and ventilation control systems, lighting and heating apparatus, heating types, etc., can solve the problems of not being able to completely accommodate this seasonal variation in non-zoned systems, unable to install a zoned hvac system, or retrofitting an existing system, and unable to meet the needs of most homeowners. , to achieve the effect of hardening and hardening the temperatur

Benefits of technology

[0018]In one embodiment, the home occupants can provide a priority schedule for the zones based on whether the zones are occupied, the time of day, the time of year, etc. Thus, for example, if zone corresponds to a bedroom and zone corresponds to a living room, zone can be given a relatively lower priority during the day and a relatively higher priority during the nig

Problems solved by technology

A non-zoned system cannot completely accommodate this seasonal variation.
Unfortunately, the equipment currently used in a zoned system is relatively expensive.
Moreover, installing a zoned HVAC system, or retrofitting an existing system, is far beyond the capabilities of most homeowners.

Embodiment Construction

[0044]FIG. 1 shows a home 100 with zoned heating and cooling. In the home 100, an HVAC system provides heating and cooling air to a system of ducts. Sensors 101-105 monitor the temperature in various areas (zones) of the house. A zone can be a room, a floor, a group of rooms, etc. The sensors 101-105 detect where and when heating or cooling air is needed. Information from the sensors 101-105 is used to control actuators that adjust the flow of air to the various zones. The zoned system adapts to changing conditions in one area without affecting other areas. For example, many two-story houses are zoned by floor. Because heat rises, the second floor usually requires more cooling in the summer and less heating in the winter than the first floor. A non-zoned system cannot completely accommodate this seasonal variation. Zoning, however, can reduce the wide variations in temperature between floors by supplying heating or cooling only to the space that needs it.

Abstract

A zone thermostat for use in connection with an Electronically-Controlled Register vent (ECRV) that can be easily installed by a homeowner or general handyman is disclosed. The ECRV can be used to convert a non-zoned HVAC system into a zoned system. The ECRV can also be used in connection with a conventional zoned HVAC system to provide additional control and additional zones not provided by the conventional zoned HVAC system. In one embodiment, the ECRV is configured have a size and form-factor that conforms to a standard manually-controlled register vent. In one embodiment, the zone thermostat is configured to provide thermostat information to the ECRV. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones. In one embodiment, the zone thermostat communicates with a central monitoring system that coordinates operation of the heating and cooling zones and provides heating and cooling to the various zones according to a cost budget.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation-in-part of application Ser. No. 11 / 668,429, filed Jan. 29, 2007, titled “SYSTEM AND METHOD FOR BUDGETED ZONE HEATING AND COOLING,” the entire contents of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a system and method for directing heating and cooling air from an air handler to various zones in a home or commercial structure.[0004]2. Description of the Related Art[0005]Most traditional home heating and cooling systems have one centrally-located thermostat that controls the temperature of the entire house. The thermostat turns the Heating, Ventilating, and Air-Conditioner (HVAC) system on or off for the entire house. The only way the occupants can control the amount of HVAC air to each room is to manually open and close the register vents throughout the house.[0006]Zoned HVAC systems are common in commercial structure...
