Thermal Control Process Apparatus

Thermal Control Process Apparatus

•    Varying the heat energy input to the system.
•    Varying the speed of a circulating fan.
•    Using a variable vane to restrict the flow.
•    Two temperature sensors measure the temperature of the block.
•    One sensor is in direct thermal contact with the block.
•    The apparatus has a variable-speed fan that forces air through a duct.
•    In the duct is an electrically-heated process block.
•    A balance of the heat gained from electrical heating and heat lost by convection and conduction gives a steady temperature at the block.
•    The other sensor mounts on an insulating spacer to introduce thermal inertia and variable-time constants into the control loop. The apparatus has scaled down time constants for shorter laboratory time.
•    A servo-driven vane, mounted after the fan and the process block, creates a variable restriction downstream for more advanced experiments.
•    The control problem is to keep the process temperature within acceptable limits while it works under various conditions.
•    A combination of regulating the electrical energy to the heater, varying the air flow rate and rotating the vane gives the heat control.
