Abstract
A heating system comprises at least one IR heating device 3 and at least one optical element arranged to focus or direct IR radiation emitted by the IR heating device 3 onto an object to be heated 1.
Claims20
A heating system for use in providing heating of persons in a building, the system comprising:
- a processing circuitry
- at least one IR heating device;
- at least one optical element arranged to focus or direct IR radiation emitted by the IR heating device onto a person to be heated;
- and
- at least one IR detector configured to detect IR radiation received directly from the IR heating device or IR radiation received indirectly from the IR heating device,
- wherein the at least one IR detector is tuned to the carrier frequency;
- and
- wherein the processing circuitry is configured to:
- control the at least one IR heating device to flash on and off in bursts at a carrier frequency;
- identify IR radiation that is emitted from the flashing IR heating device and distinguish IR radiation from that of other IR heat sources and other background IR radiation;
- and
- detect the direction of the IR radiation received from the IR heating device or IR radiation received indirectly from the IR heating device according to the carrier frequency.

A method of heating a person in a building, the method using a heating system comprising:
- at least one IR heating device arranged to flash periodically at a carrier frequency, at least one optical element, and at least one IR detector configured to detect IR radiation received directly from the IR heating device or IR radiation received indirectly from the IR heating device, wherein the at least one IR detector is arranged to detect a direction of the received IR radiation;
- the method comprising:
- focusing or directing IR radiation emitted by the IR heating device onto the person to be heated with the optical element, wherein the heating device is flashing on and off;
- detecting IR radiation received directly or indirectly from the IR heating device with the at least one IR detector;
- identifying IR radiation that is emitted from the flashing IR heating device and distinguishing IR radiation from that of other IR heat sources and other background IR radiation;
- detecting the direction of the received IR radiation with the at least one IR detector;
- and using the carrier frequency to identify IR radiation that is emitted from the periodically flashing IR heating device.
