Pipe lengths calculated for Indoor unit with Airedale Outdoor Unit match.
(1) For interconnecting pipework with a predominantly horizontal layout.
(2)
For interconnecting pipework with a predominantly vertical layout.
Tandem Compressor and suction throttle valve applications: In part load, gas velocity should be
taken into account when selecting and commissioning pipework to ensure full oil return.
REMEMBER excessive pressure loss in interconnecting pipework will impair system performance;
this should be factored in during the design of the system and where necessary oil separators
employed.
