Technical Description

• It is able to make the experiments and training for temperature, pressure of auto pressure-control device and auto defrosting
• It is able to check the changes of refrigeration device depends on different types of expansion valves
• It is able to set up the temperature scope of measurement to create the P-I diagram so it makes these experiments and trainings available such as cycle changes of equipment, Mollier diagram, and data saving.
