All of the hazards associated with ammonia are announced loudly by its pungent odor; and that odor is so strong that even at very low non hazardous concentrations, it repels people from a contaminated area. At the same time, unlike most other refrigerants, it has a characteristic odor that can be detected by humans even at very low concentrations. If evaporative-cooled ammonia systems are inherently more efficient than air-cooled Freon systems, where can Freon systems play a successful role? In ice arenas the ammonia refrigerant is in a closed loop which essentially means it is contained within the system. On larger jobs, a number of condensing units might be spread across the roof. The “Ammonia vs. Freon” debate is not a symmetrical one; the pressure is against ammonia, and for its replacement by halocarbon refrigerants. When these inefficiencies are added to the system, the BHP per ton difference is much larger than just the difference in refrigerant properties. “There is a trend to lower the storage temperature of nuts to as low as 35°F (1.7°C) to extend the storage life. Ammonia Vs. Freon . The main difference in the perception of Freon vs. ammonia systems has as much to do with the systems as the refrigerants themselves. } There are times and places where Freon systems make sense and might just be the right horse for the course. At a -40°F (-40°C) suction, the two systems are virtually identical at 2.41 BHP per ton for the R-22 system and 2.44 BHP per ton for the ammonia system.
