🧊 Water-Cooled Refrigeration System —
⚙️ System Overview
The system operates through a continuous refrigerant loop managed by the following key components:
1. Chilled Storage
The end-use space where products are kept cold. The display shows a setpoint of 3°C with an actual temperature of -5°C, indicating active cooling is in progress.
2. TXV (Thermostatic Expansion Valve)
Regulates the flow of refrigerant entering the ev***rator, controlling superheat for efficient cooling.
3. Accumulator
Protects the compressor by ensuring only v***r — not liquid refrigerant — enters the compression stage.
4. Compressor (Green unit)
The heart of the system. It compresses low-pressure refrigerant v***r into high-pressure, high-temperature gas.
5. Oil Separator
Separates lubricating oil from the refrigerant on the discharge side, returning oil to the compressor to maintain lubrication.
6. Water-Cooled Condenser
Rejects heat from the refrigerant using water as the cooling medium, condensing the hot gas into a liquid.
7. Cooling Tower
Dissipates the heat absorbed by the condenser water to the atmosphere through ev***rative cooling.
8. Water Pump
Circulates water between the condenser and the cooling tower.
9. Receiver
Stores liquid refrigerant after condensation, ensuring a steady supply to the expansion valve.
10. Filter / Dryer
Removes moisture and particulates from the refrigerant to protect system components.
11. Solenoid Valve
Controls refrigerant flow on/off based on system demand signals.
