Rectification specification of long connection pipe:
The above long connection pipe rectification is the max.capacity under standard IDU capacity allocation.
Some of load configuration is as follow:
Max.system capacity: IDU capacity and the max.capacity of ODU, take the lesser one (two kinds of
algorithms).
IDU allocation rate is below 100%
The max. capacity of ODU= the capacity in the ODU capacity rectification table when the allocation
rate is 100%×long connection pipe rectification coefficient of the furthest IDU
IDU allocation rate is 100%
The max. capacity of ODU= the capacity corresponds to the allocation rate in the ODU capacity
rectification table×long connection pipe rectification coefficient of the furthest IDU.
4.3 Rectification factor for heating defrosting
When outdoor environment has satisfied certain condition (temperature and humidity), frosting and
defrosting might occur, at this time, heating capacity of the unit will be attenuated, therefore, when
calculating heating load model selection, please add defrosting rectification factor.
Defrosting rectification factor is as follow:
Outdoor heat exchanger air inlet dry bulb
temperature (
℃
/RH85%)
-11 -9 -7 -5 -3 0 3 5 7
Defrosting capacity rectication factor 1 0.98 0.96 0.94 0.88 0.8 0.84 0.9 1
