Fundamentals of Refrigeration: Pressure/Temperature Relationship March 17th, 2026
When a substance changes state from a liquid to a vapor, the process occurs at a constant temperature. When this occurs in a refrigeration system, it is said that the refrigerant is “saturated”. For water, experiments have proven that saturation, or boiling, occurs at 212ºF at 14.7 psia, which is atmospheric pressure. However, if someone were […]
