Capacity Correction Factor; Dimensional Drawing & Centre Of Gravity; Dimensional Drawing - Daikin ERQ-AV1 Technical Data Manual

5 Capacity tables

5 - 4 Capacity correction factor

ERQ-AV1
Rate of change in cooling capacity
of ERQ100, ERQ125
Notes:
1 These figures illustrate the rate of change in capacity of the system at
maximum load under standard conditions.
Under partial load conditions there is only a minor deviation from the
rate of change in capacity shown in the figures above.
2 Method of calculating cooling capacity (max. capacity)
Cooling capacity = Cooling capacity obtained from the cooling
capacity characteristics table X Capacity correction factor
3 Method of calculating heating capacity (max. capacity)
Heating capacity = Heating capacity obtained from the heating
capacity characteristics table X Capacity correction factor
