Abstract
Systems and methods are provided for radiant heating by PTC radiant patches. A radiant heating system for warming an occupant of an enclosed space includes patches to radiate heat into the enclosed space toward the occupant. A power supply supplies electric power to the patches. A controller controls the electric power supplied to the patches based on a temperature in the enclosed space and locations of the patches within the enclosed space.
Claims20
A radiant heating system for warming an occupant of an enclosed space, the system comprising:
- a first patch configured to radiate heat into the enclosed space toward the occupant;
- a second patch configured to radiate heat into the enclosed space toward the occupant;
- a power supply configured to supply electric power to the first and second patches;
- and
- a controller configured to control the electric power supplied to the first and second patches based on a temperature in the enclosed space and based on locations of the patches within the enclosed space.
A radiant heating system for warming an occupant of a vehicle with a cabin, the system comprising:
- at least one patch configured to radiate heat into the enclosed space toward the occupant;
- a power supply connected with the patch;
- a heating, ventilation and air conditioning (HVAC) system configured to condition the cabin to a set temperature;
- and
- a controller configured to:
- control the power supply to supply electric current to the patch;
- and
- control the HVAC system;
- wherein the power supply and the HVAC system are controlled in coordination based on the set temperature.
A method of warming an occupant of an enclosed space, the method comprising:
- positioning a first radiant patch at a first location to radiate heat into the enclosed space toward the occupant;
- positioning a second radiant patch at a second location to radiate heat into the enclosed space toward the occupant;
- connecting a power supply to the first and second radiant patches;
- monitoring, by a controller, a temperature in the enclosed space;
- and
- supplying electric power from the power supply to the first and second radiant patches based on the temperature in the enclosed space and based on the first and second locations of the radiant patches within the enclosed space.
