WebR410A Pipe Sizing Charts. Brad White Member Posts: 2,393. July 2007. Normally performance would be similar "you would think", but the pressures are so radically different. (R22 at 95 degrees is 182 PSIG while R410A at the same temperature runs 298 PSIG so the pipe performance and tons carried have to be different.) WebNatural Gas Pipe Sizing Tables and Charts Steel Pipe - Schedule 40. Downstream Pressure. inlet upstream pressure is more than 5 psig (35 kPa) fittings factor 1.2 - equivalent pipe length = pipe length + 20%; For natural gas the nominal BTU/cf varies from about 900 to 1100 BTU/cf. In general it is common to set. 1 Cubic Foot (CF) = Approx 1,000 BTUs

WebFor the 3/4” vapor line, add .114 oz per foot as seen in the “Refrigerant Weight Per Foot” chart. 25’ x .114 = 2.85 oz. 13.5 + 2.85 = 16.35 oz of additional refrigerant needed . Example 3: An old R-22 packaged unit had a refrigerant leak and leaked all of the refrigerant out. The leak was fixed and the unit was pressure tested and then ... WebBest practices of selecting the proper diameters of the liquid line & suction line for split system air conditioners, heat pumps or refrigeration systems. WebJul 26, 2013 · You need to find your refrigerant type (and in the example we said R-410A). You need to get your calculator out, subtract 25 feet of line that the manufacturer already allows for from the 63 feet total line set ( 63 -25 = 38 feet). Now you need to know that pipe size so let’s say 1-1/8″ suction line and a 5/8″ liquid line (commercial unit). harry potter plast
