REFNET Pipe System EDMT331529A
502 Installation of Outdoor Units
3. REFNET Pipe System
3.1 Layout Example
3.1.1 Heat Pump
Use of the particular branch fitting appropriate to each individual unit type not only permits the pipes to be
laid with ease but also increases the reliability of the system as a whole.
Units can be added by connecting them directly to the REFNET header or REFNET joint. Further branches cannot be
included in the system below the REFNET header branch.
Notes:
1. When the capacity ratio of the indoor system to the outdoor unit is more than 100% and when all the indoor units
are in operation at the same time then the rated capacity of each unit will be somewhat reduced.
2. Special purpose REFNET pipe components must be used for all the pipe work. For further details concerning
choice of components, types of components, etc.
