CFC recovery
INTERNATIONAL JOURNAL OF REFRIGERATION is published by ButtenNorths for the Intemational Institute of Refrigeration (Institut International du Froid), 177 Boulevard Malesherbes, 75017 Paris, France. Papers are published on all subjects related to the theory and practice of refrigeration. The journal also contains news of the International Institute of Refrigeration plus more general news items, conference reports, book reviews and a list of forthcoming events. Papers will be accepted in English or French. The journal is published bimonthly. Material intended for publication should be sent to the General Editor or to the Editorial Office in Guildford. La "Revue Internationale du Froid" est 6dit~e par Butterworths pour 17nstitut International du Froid. Erie publie des articles se rapportant ~ tous sujets concernant la thdorie et la pratique du froid ainsi qu'aux sujets qui s'y rattachent. On trouvera aussi dans carte Revue des nouvelles de I'lnstitut International du Froid, des nouvells plus g6n6rales, des comptes-rendus de confdrences, une bibliographie, une liste des dvbnements futurs. Les communications doivent 6tre soumises en anglais ou en fran¢ais. La Revue est publi6e tousles deux mois.

CFC recovery At Vienna in August the Scientific Council of the IIR issued an informatory note on CFC's which will be published in the next issue of International Journal of Refrigeration. Part of its aim is to inform environmentalists that the use of R12 in domestic refrigerators and unit air conditioners is extremely widespread and beneficial, and that it cannot be substituted easily. The protocol adopted the following month in Montreal requires broadly that production of CFC's shall be frozen at 1986 levels until July 1990, when it will be progressively reduced to 50% by 1998. These controls would appear to be sensible and will allow for the use of CFC's to be concentrated in the most vital areas. Hence there is a breathing space during which sound policies can be developed. In this interval I suggest that one of our highest priorities should be to develop recovery systems for CFC's so that none is lost when units are either repaired or scrapped. Preferably the recovery system should be self-financing but it may be necessary to back them by law. My hunch is that adsorption systems based on evacuated drums of active charcoal, or similar, will provide the best approach. Have you a better idea?
