What color is the chill water used in the air conditioning process?

The color of chill water used in air conditioning systems is typically identified as yellowish or greenish. This coloration serves a practical purpose, primarily for safety and identification within a facility's piping system. Distinctive colors help personnel quickly and easily recognize different fluids, minimizing the risk of accidents or misoperations. For instance, if there were a leak or maintenance required, the yellowish or greenish color assists in determining the specific system involved, ensuring the correct procedures are followed.

In various contexts, chill water is often dyed to improve visibility; this provides a clear reference point for those working in environments where multiple systems and fluids are present. The use of this specific color is not merely aesthetic but serves a vital role in operational safety protocols within air conditioning and refrigeration systems.
