REFNET Pipe System Si39-306
270 Appendix
6. REFNET Pipe System
6.1 Layout Example
Heat Recovery System
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
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.
Special purpose REFNET pipe components must be used for all the pipe work. For further
details concerning choice of components, types of components, etc.
