A full-size, working, fluid system allowing for hands-on training in measurement and control as it relates to temperature in an industrial fluid process system. With optional instruments, the device allows control loops to be configured employing feedback and feed-forward control methods, incorporating thermocouple or RTD inputs. Variable demand
and supply disturbances can be inserted using a solenoid valve in combination with a metered ball valve.
Four, industrial-quality, heat exchangers and two immersion process heaters are provided within the unit, allowing for the creation of dynamic temperature control systems. Both the hot and utility legs can be controlled using industrialquality pneumatic control valves. Common cold tap water can be used as a cooling water source and is incorporated
through quick-disconnect fittings and valves at the rear of the training aid. An optional chiller can also be provided, creating greater temperature differentials, and more dynamic control experiments.
Areas within the piping system subject to elevated temperatures are CPVC, providing protection from elevated process heat levels. The balance of the system incorporates clear, PVC piping allowing the process flow to be seen directly. The device contains a 24 volt DC power supply and two air regulators with gauges creating an instrument air supply. All 24 volt power sources, air sources, and operational switches are conveniently located on the front panel face.
Additionally, the training aid can be used to study, in depth, the fundamentals of heat transfer within industrial heat exchangers. Four industrial heat exchanges are provided including a plate-type exchanger, and three varieties of shell and tube heat exchangers. The piping system includes multiple thermowells allowing for temperature measurement at
inlet points and outlet points on both process sides of the exchangers. A system of solenoid valves and piping manifolds allows for selection of individual heat exchanger’s for use and study. Additionally, these same features allow for flow reversal creating both concurrent and countercurrent flow capabilities. Four, digital temperature meters are
provided, allowing for direct indication and study of each exchanger using modular RTD’s in tube-side and shell-side flow as required.
A variety of optional equipment allows for complete system automation and control, using PLCs or conventional PID controllers, temperature controllers, and related instruments.
In general, the device has the look and feel of actual industrial hardware, and allows for a broad range of exercises in temperature and flow measurement and control. Additionally the training aid provides a framework for study of the heat transfer process. Through its standard features and its adaptability to optional, specialized control and
measurement equipment, it can replicate many unique industrial control arrangements. Standard, user-supplied or user-specified instruments, of any brand, can be easily installed, either on a mounting stanchion or on the built-in, 19" instrument rack.
