Refrigeration Refrigeration Pipe Dimensions Line sizing refrigeration data guidelines 2 general information this document is for reference purposes only. the refrigeration equipment installer is responsible for the actual refrigeration pipe size selection and application of the refrigeration piping. this document supersedes all previously published line sizing data – including planning. Refrigerant piping design goals a common goal is to size the suction, hot gas and liquid lines for about 1fº pressure drop at design capacity. a suction line must: • return oil from the evaporator to the compressor at minimum system capacity. • prevent oil draining from an active to an inactive evaporator when more than one.
Refrigeration Pipe Sizing Chart Printable Templates Free Using line sizing charts basis these line sizing charts are based on a suction pressure drop equivalent to a 2°f change in saturation pressure and liquid line pressure drop of 5 psi. for r 404a low temperature 1 psi; for r 404a and r 22 medium temperature 2 psi is used. this is the maximum allowable pressure drop for the entire piping run.

A refrigeration piping size chart is a tool used in hvac (heating, ventilation, and air conditioning) systems to guide technicians, engineers, and designers in selecting the appropriate pipe diameters for refrigerant lines based on various system parameters. this chart typically includes:. Refrigeration handbook and mcquay's experience with this type of equipment. a properly designed and installed refrigerant piping system should: • provide adequate refrigerant flow to the evaporators, using practical refrigerant line sizes that limit pressure drop.

The liquid line sizes provided are calculated to equal 2 °f or less in equivalent pressure drop. if the evaporator is 15 feet below the receiver the pressure from the liquid refrigerant will compensate for this pressure drop. if the evaporator is not. 15 feet or more below the receiver then refrigerant flashing may occur in the liquid line.
