20100096467 | METHOD FOR CONTROLLING HEATING APPARATUS - An object of the present invention is to provide a method of controlling a heating apparatus that is capable of automatically controlling a heating-off temperature and a heating-on temperature according to an operation environment such that upper and lower variations of a room temperature set by a user are reduced on the basis of the room temperature, thereby allowing the user to feel comfortable.

20120312885 | VARIABLE RATE HEATING FOR AGRICULTURAL PURPOSES - An exemplary temperature control system for animal confinement buildings includes an agricultural heater and a ventilation system. The agricultural heater is modified to be a variable rate heater using SmartBox technology or by applying appropriate control logic and outputs to a conventional room controller. A heat on/off relay of the room controller can serve as an enable signal connected to the SmartBox. Heating is controlled using a proportional-plus-integral algorithm for error correction. Error correction may be ceased when temperatures fall within a dead band. Heat is turned on when the temperature drops to an on temperature equal to a set point minus 0.5 F. Heat can be turned off when the heater has been at a minimum output level for a minimum output period (such as 90 seconds) and the temperature has not dropped below the on temperature during the minimum output period. An auto-variable radiant brooder may be incorporated. | 12-13-2012 |
20130026244 | WORK VEHICLE HEATING SYSTEM AND METHOD - A work vehicle comprises an internal combustion engine and a catalytic converter coupled to the exhaust of the engine. A reduction agent system provides for injection of a reduction agent, such as urea, upstream of the catalytic converter. Coolant heated by the engine is directed to the reduction agent system to defrost/heat the reduction agent, and is also directed to a vehicle cabin heating system. Flow of coolant may be preferentially directed to the cabin heating system rather than to the reduction agent system, such as following vehicle startup, particularly during cold-weather operation. Flow may be altered to favor the reduction agent system, such as based upon time and/or the temperature of the cabin. | 01-31-2013 |
