An Assessment of the Performance of Rigid Polyurethane Foam Insulation for Use in Residential Water Heaters Produced With SNAP-Approved Non-ODP Blowing Agents

摘要

In this paper,we have produced laboratory and end-use data for the major SNAP approved blowing agents available for use in rigid polyurethane insulation foams.These include HFC-245fa,HFC-134a,and cyclokpentane.This data includes a comparison of physical testing results from laboratory panels and data from EF testing and stand-by loss testing (Bayer SBLT) of heaters produced with these candidates.Specific include data on k-factor,hot and cold dimensional stability,EF and data-loss data from the Bayer SBLT.
