When we decide to install an air conditioning system that uses a multi-split motor, it is absolutely essential to consider 3 fundamental values: the number of connections (or ports), the effective yield and the maximum connectable power.

The multisplit units can be classified according to the number of connectable indoor units: dualsplit (2 connections), trialsplit (3 connections), quadrisplit (4 connections), pentasplit (5 connections) and esasplit (6 connections).

Furthermore, each "multi" type outdoor unit has its own effective yield and its own maximum power that can be connected. But what do these terms mean?
The effective yield indicates the real power that the motor is able to deliver for an undefined number of indoor units. On the other hand, the maximum power that can be connected indicates the total power of all the indoor units connected to the motor.

To better understand these two values, let's consider that we want to air-condition 3 rooms of an apartment, two of which are bedrooms and one, however, is a living room. Considering that the 2 bedrooms have a thermal requirement of 2.5 kW while the living room of 3.5 kW, we can state that the maximum connectable power is equal to 8.5 kW (2.5 + 2.5 + 3.5) and that the necessary supply power (attributable to effective) equals 5.0 kW (2.5 + 2.5). By virtue of these data, if the Mitsubishi Electric brand is chosen, it will be necessary to purchase the MXZ-3F54VF model as its effective yield and maximum connectable power satisfy the cooling and heating needs.

Therefore it is very clear that the time slots of use become a fundamental prerogative for the choice of any multi-split motor.

Below we report the sensitive data of the multisplit units, operating with the ecological R32 refrigerant gas, of the Daikin, Mitsubishi Electric, Panasonic and Samsung brands.
