What is the saturation pressure of condensed liquid at 85°F?

The saturation pressure of a condensed liquid at a given temperature represents the pressure at which the liquid will begin to vaporize at that temperature. At 85°F, specific refrigerants will have their own corresponding saturation pressures, which can be determined using refrigerant pressure-temperature charts or tables.

For many common refrigerants like R-134a or R-404A, the saturation pressure at 85°F is indeed around 151 psig. This means that at 85°F, if the liquid refrigerant is in equilibrium (saturated), the pressure would register at approximately 151 psig, indicating the point at which any additional heat supplied could lead to phase change from liquid to vapor.

Using the saturation pressure allows operators to effectively control systems, ensuring that refrigerants operate efficiently and within safe limits. Understanding these pressures aids in maintaining proper cooling cycles and managing the refrigeration system's overall health.
