Abstract:
1. A temperature conditioning system for simultaneously heating and cooling a current of air, the current of air provides a coolable current of air and a heatable current of air, the current of air flowing to and passing through a comfort zone, the temperature conditioning system comprising: a heater connected in heat transfer relationship with the heatable current of air; a heat regulator connected to adjust a heat output of the heater; a cooler connected in heat transfer relationship with the coolable current of air; a cooling regulator connected to adjust a cooling capacity of the cooler, the cooling regulator providing the cooler with a range of capacities including a maximum cooling capacity, a minimum cooling capacity, and a predetermined intermediate cooling capacity therebetween; the cooler having a first cooling range between the minimum cooling capacity and the intermediate cooling capacity; the cooler having a second cooling range between the intermediate cooling capacity and the maximum cooling capacity; a sensor system exposed to the current of air, the sensor system providing a feedback signal representative of a thermodynamic condition of the current of air; and a control system connected in signal communication with the sensor system, the heat regulator and the cooling regulator; the control system having a cooler control loop to control the cooling regulator, the control system having a heater control loop with a heater gain to control the heat regulator, the heater gain varying as a function of the cooling capacity, the heater gain having a greater range of variance over the second cooling range than over the first cooling range, and the heater gain changing polarity as the cooler changes from the predetermined intermediate cooling capacity to the maximum cooling capacity.
