Rate of change in cooling capacity
of ERQ140
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
Explanation of symbols:
Hp: Level difference (m) between indoor and outdoor unit when
indoor unit is installed below the outdoor unit.
Hm: Level difference (m) between indoor and outdoor unit when
indoor unit is installed above the outdoor unit.
L: Equivalent piping length (m)
