Key Points for Maintaining Chiller Evaporators

1. Installation of Strainer in the Water Inlet to the Chiller Evaporator Installing a strainer in the water inlet to the chiller evaporator is essential and offers numerous benefits: • Prevention of Suspended Particle Ingress: The chiller evaporator, being a sensitive component of the heat exchange system, is susceptible to damage from particles like sand, rust, and debris. These particles can reduce heat transfer efficiency and cause blockages in the system. • Difficulty in Cleaning After Contamination: Once contaminants enter, cleaning the evaporator can be...

Why Air-cooled chiller

The key difference between air-cooled and water-cooled chillers lies in how they handle condensation. Air-cooled chillers use air to cool the refrigerant, while water-cooled ones rely on a cooling tower and water. In air-cooled chillers, air passing over fin tube coils cools the refrigerant, while water-cooled chillers use water from cooling towers to cool the refrigerant through evaporation. However, this process results in a significant amount of water wastage, which poses economic and environmental challenges, especially in regions like Iran...
