Refrigeration Cycle: Refrigeration Condition Throughout the Cycle

July 21st, 2026

A savvy refrigeration professional will not only understand the vapor compression cycle, but will also know the “condition” of the refrigerant throughout the system. Let’s start with saturation. Whenever a substance changes from liquid to vapor or vice versa, it is said to be “saturated”. Additionally, a refrigerant is saturated when liquid and vapor coexist. […]

Refrigeration Cycle: Pumped Overfeed Refrigeration System

July 14th, 2026

A “pumped overfeed” or “recirc system” is similar to the gravity-flooded system in that it utilizes a vessel that was not part of the DX system. In a pumped overfeed system, however, the vessel, often called a “recirculator”, is not located above the evaporator. In fact, the recirculator may be a long distance from the […]

Refrigeration Cycle: Gravity Flooded Refrigeration System

July 7th, 2026

A “gravity-fed”, or “flooded” refrigeration system has all of the same components as the direct expansion system, but utilizes an additional vessel. Whereas the DX system piped the high-pressure liquid through an expansion device and directly into the evaporator, a flooded system is designed so that the liquid leaving the expansion valve is piped to […]
