Explain the working principle of a chiller.

Question

Accepted Answer

Chillers use a refrigeration cycle to remove heat from a liquid, providing cooling for various applications.

Chillers operate on the principle of the refrigeration cycle, which includes evaporation, compression, condensation, and expansion.
The refrigerant absorbs heat from the water in the evaporator, turning from liquid to gas.
The compressor then compresses the gas, raising its temperature and pressure.
In the condenser, the refrigerant releases heat to the environment, condensing back into a liquid.
Finally, the expansion valve reduces the pressure of the refrigerant, allowing it to evaporate again and repeat the cycle.
Examples include air conditioning systems, industrial cooling processes, and refrigeration units.
