5.4 Size of joint pipes for outdoor unit
Base on the following tables, select the diameters of the outdoor
unit connective pipes. In case of the main accessory pipe large
than the main pipe, take the large one for the selection.
Example: parallel connect with the three outdoor units 16+16+14
(the total capacity is 46HP), all indoor units total capacity is 1360,
provided that the equivalent length of all pipes are ≥90m, accord-
ing to the Table5-5 the main pipe diameter areΦ38.1/Φ22.2; in
according to all indoor unit capacity 1360, we could find out the
master unit diameter isΦ41.3/Φ22.2 base on Table.5-3. Take the
large one for the selection, we final confirm the main pipe diameter
is Φ41.3/Φ22.2.
