4) Calculate the actual capacity of outdoor units

The actual capacity of outdoor unit can be calculated as follows:
➊
Using capacity tables, get the capacity values according to indoor and outdoor design temperature and actual combination ratio.
❷
Obtain the capacity reduction rate according to max. piping length and level difference.
❸
Get the values for heating operation rates in accordance with the temperature of outdoor units
(only applicable for heating design).
❹
Using outdoor unit performance table, obtain the capacity value according to indoor and outdoor design temperature,
actual combination rates (105%).
- RVXVHT180✴✴ 110% combination capacity : 52.5kW
- RVXVHT180✴✴ 100% combination capacity : 50.4kW
=
Capacity 105%
❈ Therefore, RVXVHT180✴✴ 105% combination performance is 51.5 kW.
