Refrigerator Sysem Trainer

Product Detail Information

■Technical Description
1. The possibility of the experiment on temperature, pressure, defrosting automatic control and mechanical trouble in the automatic pressure control device
2. The comprehension of principle to refrigerator and study to refrigeration and cold system
3. The experiment on cycle change of refrigeration equipment according to temperature from two parallel evaporators and Mollier diagram drawing in P-I diagram drawing part.
4. Theoretical education of a fundamental circuit, application circuit and experiment with evaporation pressure control device
5. The compatibility and expandability of the graphic module control
6. Unlike separated system from machine department , the control department is visual automatic control with graphic panel and two automatic control modules
7. Data formation by data auto-saving and P-I diagram auto-operation in the system with control program
