Soft Refrigeration Tube, 50 ft. x 1-5/8 in. Refrigerant velocities in vertical lines should be at least 1500 ft/min to ensure good oil return; velocities in horizontal lines should be at least 750 ft/min. When hanging or fastening VRF copper refrigerant piping that involves long runs, then some form of considerations needs to be made for expansion due to temperature differences.. The presence of moisture not only robs the system of its thermal efficiency, it provides suitable conditions for mold and mildew. CO2 Refrigeration OVERVIEW Ideally suited for commercial CO2 refrigeration applications, this technically advanced tubing is a more practical alternative to steel piping due in part to familiar copper properties and the traditional joining method of brazing.

Provide the equipment manufacturer’s “Installation Manual” including required piping … Copper Air Conditioning Coil, 50 ft. x 1-1/8 in. When the system stops, the refrigerant may condense in the pipe depending on the ambient conditions. Copper, iron, stainless steel, … If no allowances are made for expansion in the ACR copper piping then leaks are possibly to occur at some point because of the stress exerted on “Y”-Branches, … We have hundreds of locations, nationwide, ready to serve your business needs. Steel is most often used in applications where the size of the pipes more than 6 inches (15 cm) internal diameter ID and ammonia (R-717) refrigerant system. Refrigerant piping shall not be placed in any elevator, dumbwaiter or other shaft containing a moving object or in any shaft that has openings to living quarters or to means of egress. The following materials should be used for all refrigerant piping: Materials: Deoxidized phosphorous seamless copper pipe or equivalent 2. Its thermal conductivity properties make it the ideal material for the refrigeration cycle, including oil management, sub-cooling, superheating, and piping of refrigerant. The refrigerant at low temperature and low pressure leaves the expansion valve and enters the copper tubing, which is connected to the evaporator or the cooling coil at the other end.
