Thermal control of a recator

This unit shows a common issue in process industry: a jacketed vessel connected to a thermoregulation group.

The aim is to run the thermal process properly, to compare the running modes and understand the consequences on the heated solutions

The user sets the different regulation loops to achieve the optimal thermoregulation process.

Various control loops (single or cascade) may be studied on this test rig. The sensor and actuator signals are available on safety

sockets and can be wired to the controller inputs and outputs as needed to form the chosen control loop.

Heat exchanger

A heat exchanger is a device used to transfer heat between a solid object and a

fluid, or between two or more fluids. The fluids may be separated by a solid

wall to prevent mixing or they may be in direct contact. They are widely used in

space heating, refrigeration, air conditioning, power stations, chemical plants,

petrochemical plants, petroleum refineries, natural-gas processing, and sewage

treatment. The classic example of a heat exchanger is found in an internal combustion

engine in which a circulating fluid known as engine coolant flows through radiator coils

and air flows past the coils, which cools the coolant and heats the incoming air.
