If you are looking for an efficient, quiet, and reliable solution to cool your spaces, you have probably come across the term "split air conditioner". But what does it really mean and why has it become the modern standard for residences, offices, and businesses?
This blog explains what a split system is, how it works, its key components, and why it can be the best decision for your property.
What is a split type air conditioning system?
The word split means “divided,” and that is the principle behind this system. Unlike window or portable air conditioners, a split air conditioner is made up of two separate units: an indoor unit (evaporator) and an outdoor unit (condenser). These are connected through copper pipes that carry the refrigerant gas and electrical cables that allow them to work together.
This design makes it possible to separate the air processing (outside) from the comfort (inside), offering less noise, greater energy efficiency, and better thermal performance.
How does a split air conditioner work?
The operation of a split system is based on a closed refrigeration cycle that extracts heat from the interior and releases it outside. Let’s see step by step how it happens:
1. Capturing hot air
The indoor unit draws in the air from the room. This air passes through an evaporator, where the refrigerant gas absorbs the heat.
2. Heat transfer
The hot gas travels to the outdoor unit through pipes. There, the compressor and the condenser release that heat into the outside environment.
3. Cooling and recirculation
Once the refrigerant has released the heat, it cools down again and returns to the indoor unit to continue absorbing more heat from the environment. This process occurs continuously until the desired temperature is reached.
What types of split air conditioners exist?
- Wall-mounted minisplit: the most common, ideal for bedrooms, offices, and small spaces.
- Cassette: installed in ceilings and distribute air evenly in four directions.
- Floor-ceiling: recommended for large areas or places where wall installation is not possible.
- Multi-split: allow multiple indoor units to connect to a single outdoor unit.
- VRF (Variable Refrigerant Flow): an advanced system that connects dozens of indoor units to one outdoor unit, with individual control for each space. It is the most efficient option for hotels, buildings, and large offices.
How to control a minisplit from your phone?
Some modern minisplits include WiFi connectivity to control them through an app, although this function is usually limited. A more complete alternative is smart controllers, compatible with any split type air conditioner that uses infrared control, without requiring the unit itself to have WiFi. With them you can turn the AC on and off, set schedules, create custom rules, and use voice assistants like Alexa.
In addition, these controllers can be complemented with smart sensors that take automation to the next level. For example:
- Turn off the AC when no one is in the room.
- Prevent use when doors or windows are open.
- Set temperature limits to control energy consumption.
Considerations before installing a split
Before choosing and installing a split type air conditioner, it is important to take into account some aspects to ensure good performance:
-
Proper capacity: check the BTUs according to the size and use of the space.
-
Location: the indoor unit should be placed where it can distribute air evenly and without obstructions.
-
Professional installation: it is important that a certified technician performs the installation to avoid leaks, failures, or excessive energy consumption.
-
Maintenance: consider periodic cleaning of filters and checking the refrigerant gas to extend the lifespan of the unit.
-
Compatibility with automation: if you want to control it from your phone or integrate smart functions, verify that your model is compatible with smart controllers.
Conclusion
The split type air conditioner has become the most popular option for cooling homes, offices, and businesses thanks to its efficiency, low noise level, and ability to adapt to different spaces. Understanding how it works and what its advantages are helps make better decisions when choosing a climate control system.
In addition, there are now solutions that go beyond traditional use: from models with WiFi connectivity to smart controllers that offer advanced automation, sensor integration, and compatibility with voice assistants. These tools not only make control from your phone easier but also help reduce energy consumption and maintain a more comfortable and efficient environment.
