# TSTCC Computer Controlled Heat Transfer Series ## 一般說明

The Computer Controlled Heat Transfer Series, "TSTCC", has been designed by EDIBON to study and compare different types of heat transfer on a small scale. It allows a wide range of heat transfer demonstrations and study the factors affecting and problems associated with different types of heat transfer.

The minimum supply consists of two main elements: Control Interface for TSTCC (Common for all "TXC" type modules), "TSTCC/CIB",and at least one of the required elements described below.

Each heat transfer module can be individually connected to the Control Interface for TSTCC (Common for all "TXC" type modules) "TSTCC/CIB", which provides the necessary electrical supply and instrumentation connections for the study of the different types of heat transfer.
