Primary Parts of a Split Air Conditioning System and Their Key Functions

27 May 2022

Property owners have been maximising various cooling systems to ensure that their buildings can remain comfortable. With the correct cooling systems, they can effectively cover large areas of properties. They can also prevent harmful elements from circulating inside.

One type of cooling system that many property owners utilise is the split air conditioning system. 

A split air conditioning system is comprised of an indoor unit and an outdoor unit. These units are then connected with a pipe, enabling the continuous transfer of the coolant between them. What makes this cooling system advantageous for property owners is it consumes power efficiently. It also has low maintenance costs, a minimal level of noise, and high-quality cooling. All these advantages are possible thanks to the following parts and components.

Outdoor Unit

The outdoor unit of a split air conditioning system is normally installed at a height above the indoor unit’s height. It can likewise be installed at a level below its indoor counterpart. The following parts of the outdoor unit enable it to be effective and efficient in cooling the air.

  • Compressor: This specific component is intended to compress the refrigerant gas. After compressing it, the unit will then transfer it to other parts in liquid form.
  • Condenser: A condenser is an outdoor unit component that cools down the air. It works by exchanging the heat with the environment.
  • Motor Fan: Works alongside the condenser, the motor fan is responsible for the movement of hot air from the said unit to the environment. It works as an exhaust for hot air.
  • Drain Hose: The drain hose of the outdoor unit intends to drain water from the condenser. While some split air conditioning systems feature a built-in pump for water removal, they still require a drain hose to prevent overflowing.

Indoor Unit

The indoor unit, on the other hand, caters to components that enable users to control the cooling of their air conditioning system. It also has components that regulate the quality of the air before sending it to various rooms and spaces.

  • Evaporator Coil: Evaporator coil is an indoor unit component that absorbs heat from the environment. It will then release the heat into the refrigerant.
  • Expansion Valve: The expansion valve of the split air conditioning system intends to expand the refrigerant flow to effectively maintain the right pressure drop.
  • Capacitor: Split air conditioning systems maximise a capacitor so they can be stabilised when starting their operations. The capacitor is also maximised to operate circuits and switch power.
  • Air Blower: The air blower of split air conditioning systems is designed to distribute the cool air into the room. It enables these systems to carry out their functions effectively.
  • Air Filter: Dust, dirt, and other particles can ruin air quality. Fortunately, split air conditioning systems typically utilise an air filter in blocking these elements. 
  • Thermostat: Ultimately, a thermostat is an indoor unit component that allows users to set their room temperature. It can be utilised in changing the temperature whenever they want.
