RETROFITTING WITH NON-CFC SUBSTITUTES BACKGROUND What is retrofit in the field of refrigeration? Retrofit is the process by which the equipment currently using an ODS refrigerant is made to run on a non-ODS refrigerant, without major effects on the performance of the equipment, and without significant modifications/changes for the equipment, ensuring that existing equipment operates until the end of its economic life. Why retrofit Imminent CFC-shortages would threaten the useful life of the appliances of CFC-equipment. As CFC shortages increase, the cost of CFCs will rise, along with operating costs of the equipment. Retrofit refrigerants and technology are available for most applications. By retrofitting the equipment, you enable it to operate past the CFC's phase-out dead lines, and the equipment lifetime exceeds the phase-out dates. Existing plants which have reached the end of their economic lifetime, should be replaced with new refrigeration equipment based on non-ODS refrigerants and technologies. This document The Executive Committee of Multilateral Fund in its 10th meeting decided to defer all retrofitting projects pending an assessment report by OORG (Ozone Operations Resource Group) on the status of retrofit, cost, reliability, cost effectiveness, and comparative benefits. This document is based on information available at the OAIC (OzonAction Information Clearing House) of UNEP IE/PAC. It is expected to provide assistance to Article 5 countries in assessing various options, and to provide input to the process of formulation of proposed strategic options (to be formulated by the Secretariat and other implementing agencies) to enable the Executive Committee to take a policy decision on the subject. RETROFIT STUDY INFORMATION Retrofit study involves the joint effort by equipment manufacturer, equipment owner, service agency, refrigerant manufacturer and research institute. Study and experiments on retrofitting have to address the following problems: Technical i) Pressure and temperature level, performance and capacity ii) Compatibility of lubricants and refrigerants with construction, sealing and insulation materials iii) Refrigerant and lubricant solubility (eg. capillary tube plugging) iv) Chemical and humidity residues and their impact on lubricants, refrigerants, materials and operation performance 4
