In refrigeration systems, “Piping drives many problems.” That’s why the International Institute of Ammonia Refrigeration (IIAR) has published the Ammonia Refrigeration Piping Handbook, combining earlier published data with substantial input from contractor experts. “Real expertise of piping lies with the contractor,” said co-author M. Kent Anderson. “A good refrigeration contractor knows piping well. Many things that go wrong with refrigeration systems can be traced back to the piping.” The Ammonia Refrigeration Piping Handbook, introduced at the Refrigerating Engineers and Technicians Association’s (RETA’s) 91st-annual conference here, has close to 400 pages, 190-plus diagrams and drawings, 50-plus charts and tables, and 30-plus formulas (pressure drop, temperature drop, capacity, and more). Coauthored by Anderson and Lane Bonebrake, it has been seven years in the making and contains a lifetime of refrigeration experience compiled from refrigeration contractors, sections of the ASHRAE Handbook and Standard 15, a long-used Vilter piping manual, and other sources..
