lines,make sure you have the correct size line based on the length of run.For example,a 3 Ton AC would need a suction liquid line sizing charts using line#190; inch suction line when the distance is 25 feet or less,but if it's over 25 feet,you would likely need a 7/8 or 1 1/8 suction line to get your full efficiency and capacity.Recommended Interconnecting Tubing (Ft) 0-25 results for this questionWhy sizing suction lines is important?Why sizing suction lines is important?Another important consideration when sizing suction lines is refrigerant gas velocity in a suction riser.Velocity of at least 1000 feet per minute is required to carry oil up a suction riser.Of course,this is only a factor when the outdoor unit is above the indoor unit and the oil must overcome the pull of gravity to return to the compressor.PIPING APPLICATION DATA SHEET - US Air Conditioning results for this questionWhat is suction line size?What is suction line size?Suction Line Sizing The line sizing charts on each case specification sheet can be used to size the subfeed branch lines.When the line serves one case.select the size specified for 50 equivalent feet for the 8 or 12 case.This may be as small as 5/8 (example service meat cases),or as large as 1-3/8 (example multi-shelf ice cream cases).SUCTION LIQUID LINE SIZING CHARTS USING LINE SIZING CHARTS
