WL 110 Heat Exchanger Service Unit Show data sheet (pdf file) Print page
Technical Description

  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: WL 110 as service and control unit and choice of heat exchanger: Tubular heat exchanger (WL 110.01), plate heat exchanger (WL 110.02), shell and tube heat exchanger (WL 110.03) and jacketed vessel with stirrer and coil (WL 110.04). Water is used as the medium.
  The heat exchanger to be investigated is connected to the service unit. The hot water flows through the heat exchanger. Part of the thermal energy of the hot water is transferred to the cold water. Reversing the water connections changes the direction of flow and thus allows parallel flow or counterflow operation.
  The main function of the WL 110 is to provide the required cold and hot water circuits. To do this, the service unit is equipped with a heated tank and pump for the hot water circuit, connections for the cold water circuit and a switch cabinet with displays and controls. A temperature controller controls the hot water temperature. The flow in the hot water and cold water circuit is adjusted using valves. The cold water circuit can be fed from the laboratory mains or the WL 110.20. The measured values can be read on digital displays. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition

software is included.

  In experiments, the typical characteristic value determined are the mean heat transfer coefficients.
  The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
