2-2. Piping limitation
CAUTION
Keep the “piping limitation” for correct operation.
• Allowable height difference:
– If the height difference between indoor unit and outdoor unit is larger than the allowable value:
The pressure loss will be larger
→ Insufficient cooling and heating
The refrigerant in liquid pipe will flush →
Refrigerant flow noise generate at indoor
unit
The refrigerant oil will not return →
Insufficient refrigerant oil resulting in com-
pressor damage
– If the height difference between indoor units is larger than the allowable value:
The refrigerant flow balance will be poor
→
Insufficient cooling and heating (poor bal-
ance)
Refrigerant oil will collect in the piping or
non-operating indoor units
→
Insufficient refrigerant oil resulting in com-
pressor damage
• Piping length:
If the piping length is longer than prescribed:
The pressure loss will be larger → Insufficient cooling and heating
Too much refrigerant will be charged →
Liquid backs up resulting in compressor
damage
The refrigerant oil will not return →
Insufficient refrigerant oil resulting in com-
pressor damage
• Pipe size:
– If the pipe size is larger than designated size:
The refrigerant flow velocity will drop. Re-
frigerant oil will not return to the outdoor
unit.
→
Insufficient refrigerant oil resulting in com-
pressor damage
The refrigerant in liquid pipe will flush easi-
ly
→ Insufficient cooling and heating
– If the pipe size is smaller than designated size:
The refrigerant circulation volume will drop → Insufficient cooling and heating
The pressure loss will be larger → Insufficient cooling and heating
