What is the process of water-cooled chillers?

Answer:

Water-cooled chillers are refrigeration systems that remove heat from a process water load and transfer it to an external water source. Here is a brief explanation of the process:1. Evaporation: The refrigerant in the chiller evaporates at a low pressure, absorbing heat from the water that needs to be cooled.2. Compression: The refrigerant vapor is compressed, which raises its temperature and pressure.3. Condensation: The hot, high-pressure refrigerant vapor is condensed in a separate condenser, releasing heat to a different water loop.4. Expansion: The high-pressure liquid refrigerant passes through an expansion valve, where it is allowed to expand and cool down.5. Evaporation: The now cool refrigerant enters the evaporator, where it absorbs heat from the process water, starting the cycle again.Water-cooled chillers require a cooling tower to reject the heat absorbed from the process water. The tower cools the water by evaporating a small portion, which lowers the overall temperature. The cooled water is then pumped back to the chiller to continue the cooling process.Overall, water-cooled chillers are energy-efficient and suitable for large industrial applications that require a continuous cooling process.
