Guide to the parts of a window and a split AC

Window ACs and split ACs are among the most commonly used air conditioning systems for residential purposes. The design of a window AC allows it to seamlessly integrate into a window opening. With all the components available in a single box, it is easy to install and affordable. Effective for cooling a single room, window ACs can generate noise, exhibit lower energy efficiency compared to a split AC, and have the potential to obstruct window views.

On the other hand, a split AC consists of an indoor unit, which includes an evaporator and a blower. Its outdoor unit has a compressor and condenser. The two units are connected to each other by means of refrigerant piping. It is quieter, more energy efficient, and suitable for different room sizes. Split ACs are costlier than Windows ACs and require professional installation.

Components of a window ACs

Here are the different components of a Windows AC:

1. Outer case: Made from sturdy plastic, the outer case of a Windows AC is usually installed in a windows frame.

2. Front panel: It is a removable component that gives access to the AC’s filter for cleaning and replacement.

3. Control panel: The control panel has knobs or a touchscreen for adjusting temperature, fan speed, and mode settings.

4. Thermostat: The thermostat can gauge the room temperature and accordingly regulate the cooling process.

5. Compressor: A compressor is the most important component of a window AC, as it pressurises and circulates refrigerant gas.

6. Condenser Coil: The condenser coil, which is placed on the outside of the AC, dissipates heat from the refrigerant into the outside air.

7. Condenser fan: To effectively expel heat, the condenser fan blows air over the coil.

8. Evaporator Coil: Positioned inside the room, it absorbs heat from the indoor air, causing it to evaporate and cool the air.

9. Evaporator Fan: The evaporator fan circulates the cool air from the evaporator coil throughout the room.

10. Expansion Valve: The expansion value controls the flow of refrigerant into the evaporator coil. It works by reducing the pressure of the refrigerant, preparing it to absorb heat.

11. Air Filter: The air filter traps dust, dirt, and other particles from the air. Thereby, it improves the indoor air quality and protects the internal components from damage.

12. Draining system: Window AC units feature a drainage system to remove condensed water from the evaporator coil. This keeps water from overflowing and causing damage.

13.Remote control: Some higher-end Windows AC models come with a remote control for controlling its different features remotely.

Components of a split AC

A split AC includes four major components, such as an indoor unit, an outdoor unit, refrigerant lines, a drainage system, and a remote control. Here’s a look at each of them.

A. Indoor unit (Evaporator)

An indoor unit comprises the following components:

1. Evaporator coil: It functions the same as in a window AC, absorbing heat from the room.

2. Blower fan: It is a powerful fan that circulates cool air throughout the space.

3. Air filter: An air filter can remove dust and other particles, improving indoor air quality.

4. Expansion valve: It regulates refrigerant flow to ensure efficient cooling.

5. Control panel: A control panel on some indoor units allows you to change settings like the temperature and fan speed.

B. Outdoor unit (condenser)

The outdoor unit of the a split AC includes the following parts:

1. Compressor: Like window units, split ACs have compressors that can pressurise and circulate the refrigerant.

2. Condenser Coil: The outdoor unit’s condenser coil dissipates heat from the refrigerant, allowing it to condense into a liquid.

3. Fan: An outdoor fan blows air over the condenser coil to expedite heat dissipation.

4. Expansion Valve: This component regulates the flow of refrigerant into the evaporate coil, controlling the cooling process.

5. Refrigerant pipes: It connects the indoor and outdoor units, transferring refrigerant between them.

6. Drain pan: The drain pan collects condensation from the evaporator coil.

7. Remote control: A remote control is an integral feature of split ACs, as it allows users to control their different functions from a distance.

By ensuring the AC’s cooling capacity aligns with your home’s size and layout, you’ll maximise comfort, energy efficiency, and long-term cost savings. Do not forget to look for star ratings or the EER (energy efficiency ratio) when purchasing an AC. The higher star ratings or EER numbers mean better energy efficiency. You can also look for other features, such as Wi-Fi connectivity, app control, voice assistant support, dehumidifier mode, auto-cleaning, and noise-less operation.
