3.1

3.1.1

Heat Pump 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.

Type of

fitting

Units can be added by connecting them directly to the REFNET header or REFNET joint.

cannot be included in the system downsteam of a REFNET header.

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 is somewhat reduced.

2. Special purpose REFNET pipe components must be used for all the pipe work. For further details concerning types

of components see Section 6.3 Example of Connection.
