125 Class

Correction factor for piping length (α)

Cooling

Notes:

1 These figures illustrate the correction factor for piping length of the system at maximum load under

standard conditions.

Under patrial load conditions there is only minor deviation from the correction factor 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 tableX Capacity

correction factor

Explanation of symbols:

Hp: Level difference between air handling unit and outdoorunit when

air handling unit is installed below the outdoor unit

Hm: Level difference between air handling unit and outdoorunit when

air handling unit is installed above the outdoor unit

L: Equivalent piping length (m)

α: Capacity correction factor
