Split system air conditioning units

An indoor and outdoor unit are the two primary parts of a split system air conditioner, which is a particular type of air conditioning system. The evaporator coil, which cools the air in the room, is located inside the indoor unit and is normally installed on the wall or ceiling of a space.

The evaporator coil in the indoor unit absorbs heat which is released by the compressor and the condenser coil in the outdoor unit. That said, let’s take a  look at the benefits and drawbacks of split system air conditioners:


  1. Effective energy use: Other forms of air conditioning systems are frequently less energy efficient than split systems.
  2. Installation is simple: Split systems can be fixed on a wall or ceiling and are generally simple to install.
  3. Silent operation: A split system’s chamber typically operates quietly, making it a great choice for usage in bedrooms and other private spaces.


  1. Low cooling capacity: Split systems may not have the power to effectively cool bigger spaces and are typically only ideal for cooling one or two rooms at a time.
  2. Costly: Split air conditioners can be more expensive than other kinds, especially if you need to install many units.
  3. Maintenance: To keep split systems operating well, they need regular maintenance for instance, filter cleaning.
  4. Split system air conditioners can, in general, be a great option for cooling single rooms or small spaces, but they might not be appropriate for larger commercial or industrial applications.

Features and functions

These are several typical features and functions when you install some split system air conditioning:

  1. Indoor unit: This part is installed inside the space that needs cooling. It has an evaporator coil that draws heat and moisture out of the air.
  2. Outdoor unit: The compressor and condenser coil are located inside this component, which is mounted outside of your house or structure. The heat that the inside unit absorbs is released by the outdoor unit.
  3. Remote control: A remote control is typically included with split system air conditioners, allowing you to change the temperature, fan speed, and other settings while you’re away from the device.
  4. Temperature sensors: Split systems frequently include temperature sensors that help control the room’s temperature and modify the cooling output as necessary.
  5. Programmable settings: A lot of split system air conditioners allow you to configure certain temperature and fan speed settings for various times of the day.
  6. Energy-saving features: Some split systems have energy-saving functions like sleep modes and energy-saving timers that can help you use less energy and pay less for electricity.
  7. Filtration systems: Split systems may also come with air filters that assist clear the air of dust, pollen, and other allergens, making them the best choice for those who suffer from allergies or respiratory conditions.
  8. Silent operation: A lot of split system air conditioners run quietly, which makes them perfect for use in bedrooms and other peaceful locations.

The operation process

Split system air conditioners cool a room’s air by expelling it outdoors following removal of heat and humidity. Here is how the process goes:

  1. The evaporator coil. The coil cools and dehumidifies the air inside the room. It is located in the interior unit. The interior unit’s fan pumps air over the evaporator coil, which absorbs heat and moisture from the air when the conditioner is turned on.
  2. The refrigerant: The refrigerant is a chemical substance that flows through the air conditioning system and removes heat from the indoor unit. The refrigerant absorbs heat as it flows over the evaporator coil and transforms it into a gas.
  3. The exterior unit: The compressor and condenser coil are located inside the outdoor unit. The refrigerant gas is compressed by the compressor, increasing its temperature and pressure. The condenser coil is where the hot refrigerant gas passes afterward to release the heat to the outside air.
  4. The expansion valve: The expansion valve controls the flow of refrigerant and is positioned between the indoor and outdoor units. The refrigerant expands and cools as it passes through the expansion valve, turning back into liquid.
  5. The cycle: After cooling and dehumidifying the air once more, the refrigerant cycles back to the interior unit. Until the target temperature is reached, the cycle continues, after which the air conditioner turns off.
