When piping and equipment.

Chilled water pipe insulation material. 2 0 role of pipe insulation for chilled water systems 33 f to 60 f 0 5 c to 15 6 c pipe insulation for chilled water systems is specified and installed primarily for process control condensation control and energy conservation. Chilled water piping is prone to unique moisture problems and presents a demanding application for insulation. In miami the cost of a chilled water system insulation job at an office building was 750 000 but hart noted that the system failed before the facility was even occupied. Failures start with design and can be aggravated by poor installation and maintenance hart explains.

In other words ambient air which is at higher vapor pressure tries to push moist air toward the insulated pipe surface where vapor pressure is lower. The phenolic foam insulation gained 400 percent to 1 000 percent. As a professional engineer my preferred method to evaluate various insulation products has always been field thermal performance test data. Insulating chilled water systems requires special attention.

Insulation is a critical component in chilled water systems. Chilled water piping heat gain british thermal units per hour per square foot. The polyurethane foam insulation gained 1 000 percent and more. Chilled water pipe insulation.

From the july august 2015 issue. Piping that carries water at below ambient temperatures creates a strong vapor drive toward the pipe.
