Title

Estimated Retrofit and Replacement Costs for Army Air-Conditioning and Refrigeration Equipment Presently Using Chlorofluorocarbons

Abstract

Recent studies have verified that the emission of manmade chlorofluorocarbons (CFCs) into the atmosphere has depleted ozone in the stratospheric layer, and may affect terrestrial ecology. In response to actions intended to reduce or eliminate the production of CFCs, the Department of Defense (DOD) has issued a policy requiring minimal use of CFCs and halons. Using baseline information calculated for the Army's air-conditioning and refrigeration (AC&R) equipment inventory based on site studies of three Army installations, information from the 1989 Red Book, and cost data from AC&R manufacturers, this study provides cost estimates for the replacement and/or retrofit of this equipment. This report includes estimates for the elimination of all Army CFC usage by replacement and retrofit. A realistic estimate of the total cost of eliminating CFC use in Army facility AC&R equipment is $150 million, based on expected retrofit of a portion of the inventory. Retrofits may be more economical for relatively new equipment. However, the industry-wide guidelines necessary to implement large-scale refrigeration system retrofits are not yet available. The estimates here will help the Army meet CFC regulatory requirements in the context of rapidly developing alternative technologies, on a cost-effective schedule.
