2.6 Piping Connections
2.6.1 General Principle For Piping
1. Use copper pipes to connect the evaporator and the condenser. Connections are
quick screw thread connections. If the line is too long and straight copper line is
used, piping joints must be brazed.
2. Follow standard industry procedures in selection and placement of pipe supports,
system evacuation and charging with refrigerant (only when pipeline is very long).
The standard refrigerant of this system is R22.
3. Give considerations to pipeline pressure drop, oil return to the compressor,
avoidance of oil logging in parts of the system and minimization of noise and
vibration.
4. Consult the factory if the equivalent length exceeds 50m, or if the vertical
difference between the evaporator and condenser exceeds the values in Table 2-3.
5. The recommend values in Table 2-3 are equivalent length. The loss of resistance
caused by elbows and valves has been taken into consideration. The installer
should confirm if these values are appropriate for site conditions.
