The Mini Ice Plant Training System (KR-112) provides a learning platform for students to understand various freezing methods in terms of Industrial 4.0 practice through wireless transmission and remote control, the structures of the components, and the operating principles of ice plant systems.
The system allows students to learn how to operate the brine cycle refrigeration and practice adjusting the concentration in brine, which can be made by various raw materials, such as salt, alcohol, and ethylene glycol. Furthermore, students can examine the influence of brine concentration on different frozen objects.
KR-112 adopts an industrial way of ice plant. Forced air cooling and water cooling are two cooling methods in the system. Different from forced air cooling by a fan under similar room temperature at a time, our transparent cooling tower enables users to simulate different heat dissipation capacity by water cooling and with variable air volume. Students can observe different effects on ice plant from changes in surrounding temperature. The Forced air cooling and water cooling can be used at the same time or separately to test different effects.
System should include the Human Machine Interface with build in programs which are the standard control method for the system operation, and the control interface is modifiable (the system provides the original program).
