Water-Cooled Chiller Components

🔷 Main Components and Their Functions:

1. Evaporator:

   • Absorbs heat from the building's circulating water (primary return).

   • The refrigerant inside the evaporator evaporates as it absorbs heat (Q_in),
     ​cooling the water which is then supplied (primary supply) for air conditioning.

2. Compressor:

   • Compresses the low-pressure refrigerant vapor from the evaporator.

   • Increases the pressure and temperature of the vapor and sends it to the condenser.

3. Condenser:

   • Transfers the heat from the high-pressure refrigerant to the condenser water loop.

   • The refrigerant condenses back into liquid form, releasing heat (Q_out).

4. Cooling Tower:

   • Rejects the heat absorbed in the condenser to the atmosphere.

   • Cools down the warm condenser water and recirculates it back to the condenser.

5. Expansion Valve:

   • Reduces the pressure of the refrigerant after it leaves the condenser.

   • Prepares the refrigerant to enter the evaporator to absorb more heat.
     

6. VFD & Motor:

   • The Variable Frequency Drive (VFD) controls the motor speed.

   • The motor powers the compressor based on load requirements, improving energy efficiency.
