It does not apply to industrial refrigeration and/or Variable Refrigerant Volume (VRV) systems. 60 feet of elevation is allowed for this liquid line size, so this This calculator is based on ASHRAE 2018 Refrigeration manual data and is provided to assist AboveAir Technologies's partners in sizing refrigerant piping. 5 lb (2 °F) 2. It can guide you in picking the right pipe size like a GPS guiding you on the road. 6 lb (2 °F) 3. com be able to do this without any pipe-size concerns. Read over to 100 feet of linear length. Pigott and . Once you understand the legend, the rest falls into The Refrigerant Piping Design program will select pipe size based on a specified maximum pressure drop in the line and compute minimum required capacity for oil entrainment in risers. Solution: Find the 10-ton unit on the left side.

J. In his paper, Pigott described his use of refrigerant as the fluid and his direct measurement of pressure drops. Subsequent reviews of analytical and empirical data for refrigerant piping resulted in the publication of two research papers: Pressure Losses in Tubing, Pipe, and Fittings by R. advantageengineering. • Line sizes are calculated at rated full load system Jul 30, 2018 ยท Figure 1. Refrigerant Pipe Sizes 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 may be as small as 5/8” (example service meat cases), or as large as 1-3/8” (example multi-shelf ice cream Refrigerant (R-410A) Piping Guide for Freon™ 410A (ENG Units) Technical Information Suction Line Size—Evaporator to Compressor 50 °F through 30 °F (145 through 99 psig) 29 °F through 10 °F (97 through 64 psig) 9 °F through –10 °F (62 through 38 psig) Suggested Allowable Pressure Drop in psig = 2 °F 4. increase power requirements (see page 8) • Refrigerant being piped DOES NOT change state. Liquid Line Sizing Example Find: Select liquid line size from table 3. His findings indicated that the pressure drop of Recommended Pipe Size (inches) 25. . For unique situations please contact Honeywell technical support. S. Start with the 5/8” liquid line size which is the rated liquid line size listed in the engineering handbook. by the American Society of Refrigeration Engineers (ASRE).
