Why is insulation important on chilled water pipes?

Insulation on chilled water pipes plays a crucial role in minimizing heat gain from the environment. When chilled water pipes are not insulated, they can absorb heat from the surrounding air. This heat gain raises the temperature of the chilled water, reducing the efficiency of the cooling system and potentially leading to inadequate cooling in the areas served by the system. By applying insulation, the heat exchange between the pipes and the environment is significantly reduced, allowing the chilled water to maintain its desired low temperature.

While aesthetics, water pressure, and preventing freezing are important considerations in piping systems, they are not the primary reasons for insulating chilled water pipes. Insulation primarily targets heat management, which is essential for maintaining the efficiency and effectiveness of cooling systems.
