When the vertical pipe height difference is less than 5 meters, an oil loop should be installed at the bottom of
the gas (large) pipe;
When the vertical pipe height difference is more than 5 meters, then for every 5 meters an oil loop must be
installed at the bottom of the gas (large) pipe, and a short loop (liquid ring) should be installed at the exit of the
indoor unit liquid (small) pipe;
When the connecting gas pipe vertical height difference is less than 5 meters but the constant rise distance is
too long, an oil loop should be installed in the gas (large) pipe every 10 meters.
◇When the outdoor and indoor units are at the same elevation, the oil deposit bend and liquid ring do not need
to be installed, if the horizontal connecting pipe length is less than 10 meters.
When the horizontal connecting pipe length is more than 10 metres, install an oil loop in the gas (large) pipe
every 10 metres.
Note:
This chart is for explanation purposes. An actual installation will differ from this according to the site conditions.
When making an oil trap the radius of the bend should be between 1.5 and 2 times the pipe diameter.
