■Technical Description
1. Available to test checking fault, temp. control, and pressure control in industrial refrigerator.
2. Available to check working situation at each evaporator by using two evaporators.
3. Available to check coolant volume at system by using coolant manometer.
4. Available to adjust evaporating pressure at each of evaporator by using EPR.
5. Available to adjust coolant volume at system by using manual V/V.
6. Available to draw p-I diagram as changing system cycle in refrigeration apparatus, since the measured section in the system should be selected.
7. Available to test performance with theory on operation of device.
8. Available to acquisition and save data of p-I diagram with program software.
