Refrigerating machine test benches:
Test 1: Glass apparatus
for the experimental representation of a refrigeration process using a low-pressure refrigerant for the basic demonstration of the function of the components.
Experiment 2: Single-stage compression refrigeration system
consisting of an air-operated evaporator, open compressor, oil separator (can be switched on and off), water-cooled condenser, mass flow meter, mechanical and electronic manometers, thermostatic and electronic expansion valves.
This system is used for comparative investigations of "old" and "new" refrigerants as well as in refrigeration engineering.
Test 3: Two-stage refrigeration system
with two-stage compression, liquid subcooling and intercooling
