[en] TEMPERATURE CONTROL SYSTEM WITH MULTIPLE NETWORKED SENSORS
申請人:OSANN ROBERT JR (US)
A temperature control system is disclosed where a single smart thermostat controls a single HVAC source according to information received through a network from multiple temperature sensors placed at different locations served by the HVAC source. This system addresses the common problem most often found in multi-cubicle and/or multi-office environments where a single thermostat controls the space and temperatures vary substantially across the space, and with the time-of-day. The system may be programmed to produce a specific average temperature across the space, or alternately target different temperatures for different locations within the space according to the time-of-day, in order to compensate for changing characteristics like the position of the sun. The system is also applicable to HVAC systems for the home.

An occupancy sensing electronic thermostat is described that includes a thermostat body having a curved exterior front surface, a dot matrix display mounted within the body viewable by a user in front of the front surface, a passive infrared sensor for measuring infrared energy and a shaped Fresnel lens having a smooth outer surface that extends across only a portion of the exterior front surface of the thermostat body. The Fresnel lens is shaped and curved so as to conform to and form a part of the curved exterior front surface of the thermostat body. A second downwardly directed passive infrared sensor can also be provided to aid in the detection of an approaching user who intends to interact with the thermostat.
