Trainer Refrigeration Control- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Trainer Refrigeration Control- Engineering Lab Training Systems.
Technical Description
The handling of a case
controller as used in commercial cooling units can be trained with the
benchtop unit. The case controller with programming unit, expansion
valve and pressure transmitter are real components. Other components of a
refrigeration system as evaporator or compressor are simulated in the
supplied software. The case controller monitors continuously the
functioning of the components and triggers an alarm when faults occur.
The
software simulates the behaviour of a freezer at different operating
states. The temperature and pressure distributions and the switching
modes of expansion valve and compressor are displayed in the screen
“measured values as a function of time”. Ambient temperature and the
refrigerant can be chosen in the system diagram, coloured buttons
indicate the operating state of the components.
All components, signal lamps, switches and a system diagram are clearly arranged on the front panel.
