Description

This product contains links to files that consist of PowerPoint slides synchronized with the audio-recording of the speaker (recorded presentation), PDF files of the slides, and audio only (mp3) as noted.

CHW pipe insulation systems sometimes fail due to long-term moisture accumulation, particularly in unconditioned spaces in humid environments. The first speaker will describe a case study of several school buildings which suffered from severe mold growth and was successfully remediated. A second speaker will describe a case study of a building that experienced extensive CHW pipe insulation failures and was successfully remediated. A third speaker will summarize the findings of laboratory tests on insulated cold pipes in ASHRAE RP-1646. Finally, a fourth speaker will address the results of computerized hygrothermal analyses simulating four different CHW pipe insulation systems.
