What is the difference between single-split and multi-split?

Step 1: Required power
In order to select a unit suitable for your needs , the required cooling or cooling capacity will be calculated in advance. heating capacity. Therefore, the size of the room as well as the intensity of the sunlight is first and foremost decisive. Since other factors such as geographical orientation, room usage or additional heat sources also play a decisive role, TOSHIBA recommends contacting a competent professional operation. He can compile an accurate and reliable calculation.

Step 2: Single or Multi-Split
Crucial for the choice between single and multi-split is the number of rooms, their size and layout in the house.
While single-split systems consist of one indoor unit and one outdoor unit connected by copper wiring, in multi-split systems up to five indoor units of your choice can be connected to a single outdoor unit. Multi-split is suitable for different climate zones and for multiple or large rooms. A big advantage is the small area required to place the outdoor unit, as well as the ease of installation.

Single-split: one-room solution. Ideal for point air conditioning.
Multi-split: multi-site solution. Suitable for air conditioning of several rooms and climate zones.

Step 3: Suitable indoor unit
In the indoor unit, the air from the room is drawn in, filtered and cooled or heated by means of a corresponding heat exchanger.
Wall-mounted, sill-mounted, cassette and ducted units vary in volume, design and filtration features. These can be freely combined with each other. For suspended enclosures, cassette units can be ideally integrated into the ceiling. If the air conditioning unit is to be almost invisible, the ducted unit can be installed under a lowered ceiling. For additional installations, sill units or wall-mounted models are recommended.

Step 4: Suitable outdoor unit
Excess heat from the interior is extracted and transported via the refrigerant to the outdoor unit.

In the outdoor unit, the heat is transferred and the refrigerant flows back into the indoor unit. The result: the air cools. Which outdoor unit is right for you is primarily determined by the power required as well as the number of indoor units that are connected.
