What is the difference between air conditioning and split systems? Aren’t they the same thing?
When it comes to cooling a building, there are many options to choose from in the air conditioning market. Sometimes, doubts arise about the difference between a split unit and an air conditioner , but in reality, a split unit is a unit that is part of a specific type of air conditioning system. In reality, the confusion stems from a terminology issue (the type of system used).
What is a split-type air conditioner?
The term “split” refers to the indoor unit (evaporator) of an air conditioning system. This unit is installed inside the building’s rooms and is part of an air conditioning system that, in addition to other components, includes an outdoor unit (condenser). The split unit is connected to the outdoor unit through a network of pipes through which the refrigerant gas circulates. Thanks to its properties, this gas helps reduce the ambient temperature within the refrigeration cycle.

Confusion sometimes arises because there are portable air conditioning units that consist solely of a single unit. The most common portable units consist of an internal compressor (condenser) that draws in air from the room, cools it, and then, through a flexible duct placed at the level of the façade, expels the heat absorbed by the refrigeration cycle from the interior of the room to the outside. This type of air conditioning is a compact climate control solution, easily transportable from one room to another in the building and with a low noise level.
Types of split air conditioning
When choosing a split air conditioning system, it’s essential to consider the area to be air-conditioned and the required power. In addition to the type of portable split air conditioning system , there are several options depending on the needs and characteristics of the available space:
Wall-mounted split air conditioning
An economical and quiet option in which the indoor unit is installed on the wall. It’s ideal for small to medium-sized rooms. It allows multiple indoor units to be connected to a single outdoor unit (multi-split system).
Ceiling-mounted split air conditioners
Ideal for large spaces, the indoor unit is installed on the ceiling. Although their installation is more complex than wall-mounted models, they are perfect for large areas such as offices and large rooms.
Floor/ceiling split air conditioning systems
ideal for commercial premises and restaurants. This type of air conditioning system offers a high level of homogeneous diffusion and is highly versatile, as the indoor unit can be installed on either the floor or the ceiling.
Ducted split air conditioning
This system stands out for its efficiency and quietness. The indoor unit is installed inside the false ceiling and requires prior installation or construction. The cold air is distributed through ducts that flow into vents located in the different rooms.
Split cassette air conditioning
Similar to a ducted system, but it distributes air in four directions, providing even coverage throughout the space. It’s installed inside a false ceiling, with only the part of the ceiling where the vents are located visible. It’s ideal for offices and commercial premises.
