👉 The neutral fluid, also known as non-condensable fluid (NCF), is a component of a refrigeration system that remains in the system even when the refrigerant is not in its vapor phase. Unlike the condensed liquid and vapor phases, neutral fluid does not condense or evaporate under normal operating conditions. It typically includes gases like carbon dioxide, water vapor, and hydrocarbons that can accumulate in the system due to leaks or improper sealing. These gases prevent the refrigerant from fully expanding and contracting, which can reduce the efficiency of the cooling process and increase the workload on the compressor. Proper maintenance to minimize neutral fluid levels is essential for optimal system performance and longevity.
