1. These figures shows the rate change in capacity of a standard indoor unit system at max. load (with the thermostat set to
the max.) under the standard conditions.
2. With this outdoor unit during cooling operation, the evaporating temperature is controlled to be constant and during
heating condensing temperature is controlled to be constant.
3. Method of calculating the cooling/heating capacity (max. capacity for combination with the standard indoor unit)
Cooling/Heating capacity = Cooling/Heating capacity obtained from the performance characteristics table x each capacity
rate of change.
When the piping length is different depending upon the indoor unit, the max. capacity of each unit during simultaneous
operation is as follows.
Cooling/Heating Capacity = Cooling/Heating Capacity of each unit x capacity rate of change for each piping length
4. Even thogh there are over-height, over-length that we guarantee, pipe length and height are followed by each
specification allowed.
