ADAPTIVE INTELLIGENT CIRCULATION CONTROL METHODS AND SYSTEMS
First Claim
1. A method of operating an HVAC system of a building, wherein the HVAC system includes a fan that is operated with fan “
- on”
time periods separated by fan “
off”
time periods to provide a desired circulation in an inside space of the building, the method comprising;
generating a random or pseudo random indicator; and
delaying a start of at least one of the fan “
on”
time periods by an amount that is related to the random or pseudo random indicator, while still achieving or substantially achieving the desired circulation in the inside space of the building.

Abstract
Adaptive intelligent circulation control methods and systems are used to help increase the comfort and/or reduce energy usage and equipment wear. In one illustrative embodiment, the circulation and/or ventilation time is adjusted based on one or more environmental conditions inside or outside the building structure. In another illustrative embodiment, the circulation and/or ventilation time may be adjusted based on the current time of day, current time of year, and/or the current schedule period. In another illustrative embodiment, the circulation and/or ventilation time is randomized over time. The start time, end time, and/or length of a circulation and/or ventilation cycle may be randomly set.
