Refrigeration Cycle: Pressure Drop

August 18th, 2026

Just as the second law of thermodynamics states, there must be a temperature difference for heat exchange to occur, so there must be a pressure difference for fluid flow to occur. Because of friction, as a fluid moves through a pipe, it will lose some pressure, which results in a ΔP. ‘Δ’ (pronounced “Delta”) is […]

Refrigeration Cycle: Noncondensable Gases

August 11th, 2026

The ideal vapor compression cycle assumes that pure refrigerant is being used, such as ammonia. Unfortunately, in the “real world,” noncondensable gases can find their way into a system. A “noncondensable gas” is an undesired foreign gas that is in the system. It travels through the cycle with the refrigerant, but it does not assist […]

Refrigeration Cycle: Compression Ratio

August 4th, 2026

“Compression ratio”, which is the ratio of the absolute discharge pressure to the absolute suction pressure, is an important concept for a refrigeration professional. Compressors are limited in the pressure differential that they can impose on a vapor. Screw compressors have the highest potential and can achieve compression ratios as high as twenty to one. […]
