Correct the cooling capacity in accordance with the conditions as follows. The net cooling capacity can be obtained in the following way.
Net capacity = Capacity shown on specification ✕ Correction factors as follows.
(1) Coefficient of cooling capacity in relation to temperatures
(2) Correction of cooling capacity in relation to one way length of refrigerant piping
It is necessary to correct the cooling capacity in relation to the one way piping length between the indoor and outdoor units.

How to obtain the cooling capacity
Example : The net cooling capacity of the model SRK12CC-1, -4 with the piping length of 15m, indoor wet-bulb temperature at 19.0˚C
and outdoor dry-bulb temperature 35˚C is Net cooling capacity = 3500 ✕ 0.975 ✕ 1.0 = 3412 w
