section for 1” pipe). This gives an allowable pipe length of 9.35 ft, which should be enough to get the relief through the roof. In practice, a contractor would “step up” to a larger pipe size in order to get more allowable length. ASHRAE 15-2001 Under ASHRAE 15-2001, Appendix H …
Aug 29, 2001 · Among a service tech’s many responsibilities is to pipe together refrigeration system components. When piping a system together, a technician must decide which pipe size to use — it’s not always as simple as it may appear. A general knowledge of piping practices is required to make an intelligent choice.
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. The program eliminates all the tedious calculations necessary when piping is sized manually and automatically corrects for all system operating conditions, interpolating and adjusting data in the tables and charts.

Good refrigeration piping design requires that the refrigeration lines be pitched in the direction of flow at approximately 1/2 inch per 10 feet or 1 inch per 20 feet. Refrigerant velocities in vertical lines should be at least 1500 ft/min to ensure good oil return;
The space between the pipe and adjacent surfaces should be three-fourths of these amounts. Hangers located close to the vertical risers to and from compressors keep the piping weight off the compressor. Pipe hangers should be placed no more than 8 to 10 ft apart and with in 2 ft of a change in direction of the piping. Hangers should be
The size of this pipe can be 3/8” up to 25 tons capacity, and 1/2” up to 60 tons. When designing a system, the engineer needs to maintain a solid column of liquid refrigerant to the flow control device,
Example: The factory supplied piston for a single−stage 3−ton heat pump is a number 57. A system is installed with 200 equivalent ft of line set. Approximately 60 ft (18.3 m) is horizontal and the outdoor unit is 140 ft (42.7 m) above the indoor unit. Table 12 shows the piston change to be +6.

excessive liquid refrigerant does not enter the com-pressor. Refrigeration compressors are designed to pump refrigerant vapor, and will tolerate only a limited quantity of liquid refrigerant. 5. Proper refrigerant feed to the evaporator must be maintained, and excessive pressure drop in the refrigerant piping …
Cleanliness of all refrigeration piping is of the utmost importance in the installation procedure. The use of gaseous nitrogen or carbon dioxide flowing at low pressure through the lines while they are
Refrigeration systems contain refrigerant under pressure. Puronr refrigerant (R--410A) systems operate at higher pressure than standard R--22 systems. Use only service equipment and components rated for Puronr refrigerant. Extreme caution should be observed when handling refrigerants. Wear safety glasses and gloves to prevent personal injury.
