Refrigerating unit (flow & temperature control)

Features:

Flow measurements (vortex, thermal mass)

Temperature measurements (PT100, PT1000, Thermocouple J, Thermocouple K, displays/transmitters)

Valves (control valve with electro-pneumatic positioner and back to position)

Pumps (volumetric with rotary vanes controlled by a speed drive, analog control and information feedback)

Converter (voltage-to-current, current-to-current)

Process components (plate exchanger, automatic air valve)

Industrial refrigeration (condensing unit, pressure reducer, filterdrier, HP/LP pressure switch…)

Communication & Fieldbus (Ethernet, Hart)

Process control (controller, PLC, DCS)

Training activities:

Studying the main principles of measurement (physical laws, sensors, transmitters..)

Calibrating sensors (flow, temperature)

Open-Loop and Closed-Loop systems identification

Analysis of the control valve (direction, flow coefficient Cv, characteristics)

Analysis of a naturally unstable OL and CL system

Flow and/or temperature control in closed-loop (study of PID actions)

Combined / trend control, cascade, self-selective,…

Thermal balance, exchanger power

Study of the refrigeration cycle

Programming different process controllers (controller, PLC, DCS)

Key points:

3 different controllers may be used

Ideal for studying industrial instrumentation and temperature / flow

Studying a refrigeration cycle system for chilled water production

Training system based on a real application (chilled water production in a soft drinks production line)
