Two-stage phase out in domestic refrigerator foam
129. Several projects were submitted for conversion of domestic refrigerator insulation foam. The two commonly available technologies, HCFC-141b and cyclopentane, were each represented. Conversion costs were frequently higher for cyclopentane, because of safety requirements arising from the use of a flammable agent. However, for cyclopentane technology, this was a once-only cost. Additional conversion costs would normally be required in due course to convert HCFC-141b plants to ODS-free technology. As HCFCs were not controlled substances for Article 5 countries, incremental costs for conversion of HCFC-141b plants were not eligible for funding. Implementing agencies should note a presumption against HCFCs when preparing projects. Where HCFC projects were proposed, the choice of this technology should be fully justified and include an estimate of the potential future costs of second-stage conversion. The Executive Committee requested implementing agencies to take this issue into consideration when preparing projects for domestic refrigerator insulation foam conversion.
