Refrigerant Piping Design Guide - 15000 Inc.Refrigerant Piping Design Check List The first step in refrigerant piping design is to gather product and jobsite information. A checklist for each is provided below. How this information is used will be explained throughout the rest of this guide. Product Information • Model number of unit components (condensing section, evaporator, etc.)
Refrigeration piping I: Here are the piping basics - ACHR NewsRefrigeration is the process of moving heat from one location to another by the use of refrigerant in a closed cycle. A refrigeration cycle consists of oil management, gas and liquid separation, subcooling, superheating, piping of refrigerant in a liquid and gas, and two-phase flow in the condenser drain line.
How to Size Refrigeration System Piping - ACHR NewsIn the liquid line, since the refrigerant is in its liquid form, it tends to mix well with the refrigerant and is carried along easily. Most manufacturers will include recommended pipe sizes with their installation and service literature. Technicians need to refer to this material when piping in any component.
