A 1.25" diameter chilled water must be insulated with pipe insulation that is at least how thick?

• A. 0.5"
• B. 1.0"
• C. 1.5"
• D. 2.0"

Answer: (C)

For a 1.25" diameter chilled water pipe, insulation thickness is important to prevent heat gain from the surrounding environment, which can lead to inefficiency in the cooling system. Industry standards often dictate the minimum insulation thickness based on the size of the pipe and the specific application. In this case, a thickness of 1.5" is recommended for chilled water pipes of this diameter. This dimension helps achieve the necessary thermal resistance to minimize energy loss, ensuring that the chilled water remains at the desired low temperature as it travels through the system. Using thicker insulation, like 1.5," also helps mitigate condensation issues, a common concern with chilled water pipes in humid environments. This thickness provides a good balance of thermal efficiency and cost-effectiveness while adhering to best practices in the HVAC industry. Therefore, for a 1.25" chilled water pipe, selecting insulation of at least 1.5" thick is aligned with the guidelines for efficient and effective insulation practices.
