Dear all,

I need to make particular reference to a  BD+C project's technical description with respect to VRV/VRF piping insulation. However:

1. Table 6.8.3A (Heating) does not list refrigerant.

2. Exception d of 6.4.4.1.3 excludes liquid refrigerant pipe.

3. Refrigerant temperatures vary between gas line, liquid line and low pressure vapour line (heat recovery 3 pipe system).

Any thoughts?
