A newly developed, no-ozone-depleting refigerant blen containing a fluoroidocarbon compound was compared wit R-22 in a laboratory-scale, water-to-water refrigeration cycle test loop. The loop is equipped with a coaxial tube-in-tube condenser, a baffied shell-in-tube evaporator, and a variable-speed compressor. The blend and R-22 were tested at saturated evaporator temperature conditions of about-10 deg F to-20 deg F and saturated condenser temperature conditons rom about 80 deg F to 100 deg F. The compressor speed was varied such that evaporator (cooling) capacity was held constant at approacimately the same value for both refrigerants for each test condition. To maintain equal capacity, results showed the compressor speed for the blend to be at least 53
