SV Technocrats India’s vapor compression refrigeration test rig is a specialized educational tool used to demonstrate and study the principles and operation of vapor compression refrigeration systems. This type of test rig is commonly used in educational institutions and training centers to provide hands-on learning experiences for students studying HVAC (Heating, Ventilation, and Air Conditioning) or refrigeration engineering.
Key Components
1. Compressor: Often a small-scale version of a commercial compressor, responsible for compressing the refrigerant and increasing its pressure and temperature.
2. Condenser: A heat exchanger where the high-pressure, high-temperature refrigerant releases heat and condenses into a liquid.
3. Expansion Valve: A throttling device that reduces the pressure of the refrigerant, causing it to cool significantly before entering the evaporator.
4. Evaporator: Another heat exchanger where the low-pressure refrigerant absorbs heat and evaporates, cooling the air or fluid that passes over it.
5. Refrigerant: The working fluid that circulates through the system, typically R134a, R404a, or similar.
6. Pipes and Tubes: Connecting all the components and facilitating the flow of the refrigerant.
7. Pressure Gauges and Thermometers: Instruments for measuring the pressure and temperature at various points in the system.
8. Flow Meter: Measures the flow rate of the refrigerant.
9. Electrical Control Panel: Contains the necessary controls and safety devices to operate the system.
10. Data Acquisition System: (Optional) For logging and analyzing performance data in real-time.
