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 […]

Fundamentals of Refrigeration: Pressure

December 9th, 2025

Pressure is the measurement of a force applied over an area. The equation to calculate pressure is Pressure equals Force divided by Area. Imagine that a 200-pound man stood on top of a table that has a 10 square foot area. Assuming the man’s weight could be evenly distributed across the table, the pressure exerted […]
