The Recycle Loops Unit, "TRLB", has been designed to demonstrate, both visually and experimentally, what a recycle loop is and how itworks. It has many teaching applications, among them the performance of mass and energy balances under stable and unstable stateconditions.
In this unit an inlet water flow is thermally conditioned in a recycle loop to obtain an outlet water flow that fits the desired conditions.
The unit consists of a tube that carries water from the cold water supply to a drain and a loop connected between the supply and the drainconnections. This recycle loop includes a pump and a heating element to increase the water temperature inside the loop.
Different volumes of the recycle loop can be selected by just opening the corresponding valve.
The residence time of each configuration can be studied. The loop flow variation has important didactic properties. The recycle loop isregulated through that variation.
The water temperature at the inlet, outlet and inside the loop are measured with temperature sensors. The water flows in the correspondingpoints are measured with flow sensors.
