How to obtain the cooling and heating capacity
Example : The net cooling capacity of the model FDCA301HEN with the air flow “High”, the piping length of 15m, the outdoor unit
located 5m lower than the indoor unit, indoor wet-bulb temperature at 19.0 ˚C and outdoor dry-bulb temperature 35 ˚C is
Net cooling capacity = 7200 × 1.00 × (0.989 - 0.01) × 1.0 = 7049 w
