VARIABLE RATE HEATING FOR AGRICULTURAL PURPOSES |
摘要 |
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. |
