A system sizing calculation for multizone ductless air conditioners that plans for diversity may size up to approximately 130% of indoor unit demand versus the outdoor unit’s system capacity provided that planned operating demand throughout the day never exceeds 100% of system capacity. If there is no planned Diversity then the indoor unit demand should not exceed 100% of the outdoor unit capacity.
Therefore, a first step in sizing and selecting any multizone system is to understand the System Demand that the building requires before moving on to selecting Indoor unit combinations.
