Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).
Rules of thumb: I don’t do meat unless it’s refrigerator temperature outside (so, rarely, as it’s still annoyingly warm in the Boston area) Never take anything with a compromised packaging/seal
