Heat exchangers transfer thermal energy from the flow of one medium to another. The two flows do not come into direct contact with one another. Efficient heat transfer is a prerequisite for economical processes. Therefore, different heat exchanger types are used in practice depending on the requirements.
This experimental unit can be used to investigate and compare different heat exchanger designs. The complete experimental setup consists of two main elements: as supply and control unit and choice of heat exchanger: Tubular heat exchanger, plate heat exchanger, shell and tube heat exchanger and stirred tank with jacketed vessel and coil. Water is used as the medium.
