Circulation speed of the refrigerant
Refrigerant mass
DISCHARGE LINES
In heat pump operation, the gas line works as discharge line.
LINES POSITION
1. When indoor unit is at a lower level than outdoor unit:
It is not essential to install traps in the vertical line. However, it could be convenient to install some every 6 to 9 meters
in order to help oil return.
When working with the machines in operation, discharge line temperature is
very HIGH and could result in burns.
