Smart Air Handler using ProMPT™ and the PIC18F2539
In many heating, ventilation, and air conditioning (HVAC) applications, air handler
motors are either off, or on at full speed. However, by adding variable speed
control to the air handler, significant energy savings over the standard on/off
control can be realized, resulting in significantly reduced cost of operation.
This application note discusses the implementation of a variable speed air handler
that utilizes a single phase AC induction motor. The task of designing the variable
speed air handler is greatly simplified by using the Microchip Programmable Motor
Control Processor Technology (ProMPT) Single Phase Induction Motor Control Evaluation
Kit and the PIC18F2539 microcontroller.
