This multi-purpose, realistic and safe educational system allows for the investigation, demonstration and analysis of a
variety of common heat exchanger types used in industry. The standard package includes a shell and tube-type heat exchanger.
The base unit allows for the connection to the standard shell and tube heat exchanger, as well as multiple optional heat exchanger varieties. The device is fully instrumented. Each heat exchanger allows for investigation of heat transfer properties including, energy balance and efficiency calculations, determination of Logarithmic Mean Temperature Difference (LMTD) and Overall Heat Transfer Coefficient (U). The effects on heat transfer coefficient from different fluid flow rates and temperature differences can be seen. Using optional heat exchangers, comparisons in operation and performance between heat exchanger types can be made. All heat exchangers allow for demonstration of the differences between parallel and countercurrent operation. Additional experiments relating to heat loss and reduction in heat transfer due to tube fouling are possible as expanded student projects.
The system is useful with in a variety of university-level engineering applications, as well as within industrial technical training programs relating to instrumentation, process control and process technology.
