Footnotes
1) For interconnecting pipework with a predominantly horizontal layout
2) For interconnecting pipework with a predominantly vertical layout
3) Double risers should be used on vertical suction / discharge lines for heat pump systems where the BluCube is below
AHU.
A single riser will not be sufficient to minimise pressure loss.
4) V
ertical liquid lines greater than 20m are not permitted on any system
Assumptions
i) In cooling mode - evaporator temperature = 7°C and condensing temperature = 50°C
ii) In heating mode - evaporator temperature = -10°C and condensing temperature = 50°C
