Generally, an air conditioning unit consists of an indoor unit (split) and an outdoor unit, but nowadays you can already have an outdoor unit and eight indoor units.
This is why the Multi-split concept arises, whereby several indoor units are connected to a single outdoor unit.
A multisplit air conditioner is a variant of air conditioning that instead of having two units, one interior (with evaporator, fan, air filter and control system) and another outside (with compressor and condenser)
Here arise the concepts 2 × 1, 3 × 1, 4 × 1 … which refer to, first, the number of indoor units, and second, the number of outdoor units.
Advantages of multisplit
For the air conditioning of several rooms with air conditioning it is interesting to buy this system.
- Savings on installation (only one outdoor unit is installed)
- Space saving, by eliminating outdoor units
- A single compressor for different solutions
Do you use a 2×1 multisplit more than two separate air conditioners?
No, because although the external equipment is more powerful, being an inverter, when only one room is turned on, the compressor works at very low speeds. A good inverter electronic system is recommended so that this regulation of the compressor, before different temperature changes, is as sensitive as possible to avoid large increases in the speed of the same to correct said temperature changes.
