You should give an experience and train on temperature control,
automatic pressure control device pressure, and automatic defrost.
You should give an experience and educate theoretically about the
automatic control of the refrigeration system and the refrigerator
components.
You must establish the temperature range measure to create the P-I
Diagram, so that these experiments and training are available, such
as equipment change cycles,Secondary heat exchange, through the
heat accumulation tank.
You should check and adjust the flow of the heating medium (Water)
You must obtain the most accurate data through the high and low
pressure switch.
The heat accumulation tank must be able to be visualized through
transparent acrylic and the thermotherapy must circulate through
the circulator.
It should be structured in order to accumulate heat, to be able to
see the states and flow of the refrigerant, and to understand the
principle of the components, so as to maximize the achievements of
education.
It must be composed of accessories, in order to visualize the
state, principle and flow of the refrigerant.
You must have the power control (ON / OFF), monitors and data
stored in the computer of the electrical control panel, through
software.
Must have fault insertion and simulation
