4.8.4 Symmetric connecting pipework AIR 80 C22A
The liquid pipework to the two VHS-M 80 evaporators is to be distributed symmetrically (Fig. 18)
•
1 x liquid pipework upstream of the distribution: Cu, 22x1mm
•
2 x liquid pipework downstream of the distribution: Cu, 16x1mm
•
Pipework lengths downstream of the distribution (s1=s2): max. 3m
•
Difference in pipework lengths between s1 and s2: max. 0,5m

The suction gas pipework is also to be distributed symmetrically (Fig. 19):
•
1 x suction gas pipework upstream of the distribution: Cu, 42x2mm
•
4 x suction gas pipework downstream of the distribution: Cu, 22x1mm
•
Pipework lengths downstream of the distribution (s1=s2=s3=s4): max. 3m
•
Difference in pipework lengths between s1, s2, s3 and s4: max. 0,5m
