4.5 Accessory pipe in the pipeline
Because of different mounting positions of the air conditioning, the required accessory pipe can be long or
short, to avoid affecting the amount from too long cooling pipe, please select a reasonable tube length
according to table below, try to select the location of the short lines for the installation.
1. The maximum allowable operating distance away from the pipe
Note: On condition that 80% of the cooling capacity is guaranteed, in the above parameters, the cooling
capacity loss and return oil has been fully considered.
2. The use of oil return elbow
When the height difference between the indoor and outdoor unit is greater than 5 m, in order to facilitate oil
return of the compressor, oil return elbow must be used. Upon site operations, the following typical installation
methods can be referred to (see Figure below).
Backstop elbow
Gas pipe
Oil return pipe
Indoor unit
Note: Oil return elbow radius R ≤100mm, 10 oil return elbows must be located per 5m as shown above; when
the height difference between indoor and outdoor unit exceeds five meters, oil reserve elbow and backstop
elbow should be set according to the relative position of outdoor unit and indoor unit.
