(2) Calculation method of heating capacity---Heating capacity to be known=Heating capacity x(AxBxCxDxExF) W
A. Capacity modification value
under indoor air dry-bulb
temperature condition.
D. Capacity compensation
suitable for total capability of
indoor unit group(heating)
F. Heating compensation factor at different pipe length
Pipe length of single way (m)
Outdoor modified capacity heating or outdoor capacity after modify item 1 and 2 )
(3) Calculation method of refrigeration capacity-Only one indoor unit running
Outdoor modified capacity with a single indoor running=outdoor modified capacity*
E. Capacity compensation coefficient for defrost
capability of outdoor heat exchanger.
Total capacity of indoor unit group(%)
Outdoor air wet-bulb temperature
Outdoor air wet-bulb temperature
B. Capacity modification value under outdoor air
wet-bulb temperature condition.
C. Capacity modification value
under airflow variation rate of
indoor unit group.
stand by indoor normal capacity
indoor total normal capacity.
