What is the maximum allowable amount of non-condensable gas in a propane refrigeration system?
In propane refrigeration systems, the accumulation of non-condensable gases (such as air) reduces system efficiency, and in severe cases, it can also pose safety hazards. Generally, it is recommended that the volume fraction of non-condensable gases be kept below 1% of the total system volume. If this amount is exceeded, it is best to remove it promptly through a venting device (such as a relief valve). In practice, it is best to regularly check the relationship between system pressure and temperature; if any significant abnormalities are detected, exhaust should be considered. The specific values should be determined based on the recommendations of the equipment manufacturer and the system design parameters; differences may exist between different systems. .
