Abstract
NASA has issued an interim policy requiring all of its Centers to eliminate consumption (purchase) of stratospheric ozone-depleting substances, including chlorofluorocarbons (CFCs), by 1995. Also, plans must be outlined for the eventual phaseout of their usage. The greatest source of CFC consumption and usage at the Goldstone Deep Space Communications Complex is refrigerant R-12, which is used in many of the facility’s air-conditioning systems. A pilot retrofit test shows that retrofitting R-12 air-conditioning systems with hydrofluorocarbon R-134a would be a workable means to comply with the R-12 portion of NASA’s policy. Results indicate acceptable cost levels and nearly equivalent system performance.
