Chilled-water-pipe-insulation-types, as summer arrives and puts more stress on chilled water systems, proper insulation of these pipes will help you avoid massive failures. unconditioned spaces in hot and humid climates are of particular concern, though these practices should be applied everywhere.. Chilled water systems play an important role in meeting the cooling needs of industrial and commercial facilities. because chilled water pipes operate below ambient temperatures, proper insulation can protect these pipes from moisture and condensation problems such as corrosion and mold growth., guide to insulating chilled water piping systems with mineral fiber pipe insulation 33°f to 60°f (0.5°c to 15.6°c) firstedition,2015.
Chilled water pipe insulation. by william a. lotz, p.e. from the july/august 2015 issue. as a professional engineer, my preferred method to evaluate various insulation products has always been field thermal performance test data., cellular glass, glass fiber, phenolic foam, and polyurethane foam are popular materials for insulating chilled-water pipe. as tests i recently concluded confirm, in hot, humid climates, there are significant differences in thermal performance over time between them.. A chilled-water system can be defined as a re-circulating water system using water chilled in a refrigeration machine as a source for cooling. in most commercial applications, this cooled water is used as part of an hvac system for conditioning the temperature of the air in a room or building. we often think about the, page 3/ 5 20/11/2008 2. photos of insulation for chilled water and domestic cold water pipes photo 1 photo 2 photo 3 photo 4 photo 5 photo 6.
Proper mechanical insulation of chilled-water piping is critical. the life-cycle cost savings and risk avoidance made possible by insulating chilled-water piping is vital to the design of a high-functioning system. chilled-water pipe insulation is the wrong place to attempt value engineering when designing new or replacement piping. incorrect product selection or using untrained installers can, columbia university facilities design standards mechanical 15251 - pipe insulation for hvac systems a. design criteria. comply with more stringent of following latest edition of energy conservation.
All three grades are flexible and resilient closed-cell expanded foam insulation. the maximum water vapor permeability is 0.10 perm-inch and the maximum thermal conductivity at 75°f temperature is 0.28 btu in/(h ft 2 f) for grades 1 and 3 and grade 2 is 0.30 btu in/(h ft 2 f). grade 3 formulation does not contain any leachable chlorides, fluorides or polyvinyl chloride or any halogens.
