3. The training platform visually demonstrates the system structure and working principle of the refrigerator. The structure of the refrigeration system and the physical objects of the main components can be clearly seen. The system is also equipped with current flow voltmeter, AC ammeter, pressure gauge, signal indicator, etc., so that the real-time working status of the entire air conditioning system and refrigerator system can be seen at a glance.
4. Refrigerator cabinet: It is made of plexiglass to show the principle of evaporator directly, and the temperature can reach -5 degrees.
5. Test bench: It is made of aluminum alloy structure, the left side is blue and the decorative board and panel, the whole is blue,
6. The equipment has 4 thermometers, which can measure the main temperature changes of the refrigeration system.
3. Configuration list
4. Experimental function:
1. Identify various refrigeration components.
2. Carry out various refrigerator refrigeration and system debugging.
3. Demonstration of the principle of air-cooled refrigerator
4. Control experiment of air-cooled refrigerator
