## 一般說明

The Shell and Tube Heat Exchanger for TICC, "TICT", designed by EDIBON, provides a comprehensive environment for the study of heat transfer. It allows analysis of the overall energy balance, heat losses in parallel and counterflow configurations, as well as temperature distribution and exchanger efficiency. Furthermore, it facilitates exploration of key parameters such as Reynolds number, Prandtl number, and Nusselt number.

This unit, comprising a series of tubes through which hot water flows and a space between the inner tubes and the casing for cooling water, offers detailed practices for studying and analyzing heat transfer. These practices include overall energy balance, heat loss studies, temperature distribution, and calculation of logarithmic mean temperatures.

Additionally, the ε-NTU method is used to calculate the efficiency of the exchanger, and the influence of flow rate is investigated by analyzing Reynolds and Prandtl numbers. Nusselt number and convection heat transfer coefficients are also determined for each flow.

In summary, the Shell and Tube Heat Exchanger for TICC, "TICT", provides students, teachers, and researchers with the opportunity to delve into the fundamental principles of heat transfer in shell and tube exchangers. With its innovative design, this unit offers a detailed understanding of the process.

To work with this unit, the Base and Service Unit, "TIUS", is required, which provides key functions such as heating water using a thermostatic bath, pumping hot water, regulating and measuring the flow rates of cold and hot water, measuring the inlet and outlet temperatures of cold and hot water, as well as measuring the pressure drop in the heat exchanger.

These Computer Controlled Units are supplied with EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
