Daikin gas tight joints model and quantity may change depending on the actual piping length and
the installation.
Daikin gas tight joints for field piping can only be calculated for systems where the individual pipe
lengths are input.

Required cooling capacity towards the outdoor unit: 46.4kW.

Required heating capacity towards the outdoor unit: 54.2kW.
The sum of the required indoor unit capacities is 46.4kW for cooling and 54.2kW for heating.
However, the outdoor unit selection uses reduced load values for cooling of 41.8kW (= -10%) and for
heating of 48.8kW (= -10%).
Be aware that unrealistic reductions may lead to reduced comfort levels, different noise levels or
increased wear and tear.

Outdoor unit placed 90.0m above the indoor units.

The maximum height difference between the outdoor unit and an indoor unit placed below it (90.0m)
exceeds 50.0m. The main liquid pipe is sized up
The minimum connection ratio for this height difference is 50%.
