Total cooling balance
(1) Do not take into account if the partitions are in contact with an air-conditioned location.
(2) Only take into account the effective outputs at the hottest times of day
* Note
: This balance corresponds to approximately 5 to 6 °C cooling compared to the outdoor temperature. For a higher
value, it is recommended to create a detailed balance.
