Calendar-based method for controlling a matrix -based air conditioning system
Disclosed is a process providing a capability for controlling an air handling system implemented using a matrix layout, for example a grid based air-handling system in a building A matrix-based air conditioning system for improved efficiency, available at http://www.google.com/patents/about?id=7sznAAAAEBAJ, as U.S. Patent Application Publication 2010/0318226, published December 16, 2010.
. Using the disclosed process, each crossing section of a control system has a set of valves that can be controlled remotely used for driving airflow to desired locations.
Given an air conditioning system deployed in a matrix layout in an office building, the disclosed process enables automatic control of airflow and temperature using events stored in calendar system of a user. Using events contained in the calendar in combination with predetermined data (for example, average heat emission per person), an embodiment of the disclosed process determines the number of people in each room of the building, calculates which valves need to be opened and which air conditioning machines need to be active, and routes the cooled air to the required spots. An embodiment of the disclosed process typically saves energy because cooled air is routed only to desired locations and all air conditioning machines are not required to be active at the same time.
An embodiment of the disclosed process enables an air-conditioning control system integrated with a calendaring system of an enterprise enabling cooled airflow to be optimized to save energy. A calendaring system event includes fields for event time and duration as well as event location. The disclosed process uses the calendaring system information to determine where users are located in the building. Using this information, plus previously stored data including average heat dissipation per person and average heat dissipation per computer, an embodiment of the disclosed process calculates which air-conditioning machines to turn on and which valves to open/close to route cooled air flow to a room, bringing the temperature to a desired level. When there are no events in an calendar of a user, the embodiment of the disclosed process assumes user is in a room belonging to the user.
The disclosed process provides a capability for a control system designed for a matrix layout air conditioning system. Each crossing section has a set of valves that can...
