  • Concentric Heat Exchanger Trainer Thermal Training Equipment Teaching Equipment

    WL-302 Concentric Heat Exchanger Trainer Thermal Training Equipment Teaching Equipment
    The Concentric Heat Exchanger should investigate the fundamental principles of heat transfer as applied to a liquid-to-liquid heat exchanger. A simple arrangement of valves allows operation as either a parallel flow or counter-flow heat exchanger enabling temperature profiles, energy balances, heat transfer coefficients and log mean temperature differences to be obtained for both conditions.
    DESCRIPTION
    The apparatus should required only a cold water supply, single phase electrical outlet and a bench top to enable a series of simple measurements to be made by students needing an introduction to heat exchanger design and operation. Experiments can be readily conducted in a short period of time, without the need of setting up operations, to accurately show the practical importance of the followings:
    a) Temperature profiles
    b) Co- and counter-current flow
    c) Energy balances
    d) Log mean temperature difference
    e) Heat transfer coefficients
    The equipment Should consists of a concentric tube exchanger in the form of “U”, mounted on a support frame. The external surface of the exchanger is insulated. Six temperature sensors are installed in both the inlet and outlet tubes, to measure the fluid temperatures accurately. To minimise losses in the system, the hot water is fed through the inner pipe, with the cooling water in the outer annulus. Control valves are incorporated in each of the two streams to regulate the flow. The flow rates are measured using independent flow meters installed in each line. Temperature and flow readings could continuously being
    captured and logged into the computer with optional Data Acquisition System. These data are useful for further calculations and analysis. On-line trending display allows student to observe the fluctuations of flow and temperature readings immediately.
    The hot water system is totally self-contained. A hot water storage tank is equipped with an immersion type heater and a temperature controller. Circulation to the heat exchanger is provided by a pump, and water returns to the storage tank via a baffle arrangement to ensure adequate mixing. The cold water required for the exchanger is taken from the laboratory mains supply.
    A readily identifiable valve arrangement allows simple change-over between co- and counter-current configurations.
