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

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

Furthermore, each "multi" outdoor unit has its own effective yield and its own maximum connectable power. 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. Instead the maximum connectable power indicates the total power of all the internal units connected to the motor.

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

Time Slots

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

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