Key Components of Chillers

Chillers have several main parts that work together:

• Compressor: This part pushes the refrigerant, making it hotter and under pressure.

• Condenser: It cools the refrigerant, turning it from gas to liquid.

• Evaporator: This part takes heat from the liquid being cooled, turning the refrigerant back into gas.

• Expansion Valve: It controls how much refrigerant flows, keeping the cooling process smooth.

• Control Systems: These systems help monitor and adjust the temperature precisely.

These parts work as a team to keep things cool. That’s why chillers are so important for industries needing exact temperatures.

The Cooling Process in Chillers

Chillers cool things by following a step-by-step process:

1. Heat Absorption: The liquid to be cooled goes into the evaporator. The refrigerant takes heat from the liquid, making it cooler.

2. Compression: The refrigerant, now gas, moves to the compressor. The compressor makes it hotter and under pressure.

3. Heat Release: The refrigerant goes to the condenser, where it releases heat into the air or water. This turns it back into liquid.

4. Expansion: The refrigerant passes through the expansion valve. This lowers its pressure and temperature. Then, it goes back to the evaporator to start again.

This cycle keeps things cool for many uses. Factories use chillers to stop heat problems, and food companies use them to keep food fresh.
