A split system air conditioner is a cooling device that consists of two main units: an indoor unit and an outdoor unit. The indoor unit, typically located inside the room, contains the evaporator coil, which cools the air. The outdoor unit has a compressor and a condenser coil, which releases the heat absorbed from the indoor air.
Here’s how it works. First, the indoor unit draws warm air from the room and passes it over the evaporator coil. This coil contains a special refrigerant liquid that rapidly absorbs the heat from the air. The refrigerant, in its gas form, then travels to the outdoor unit through a series of copper pipes.
The outdoor unit’s compressor pressurizes the refrigerant, causing it to become superheated. As a result, the refrigerant greatly increases in temperature. The hot refrigerant passes through the condenser coil, releasing the collected heat into the external environment. This process transforms the refrigerant gas back into a liquid.
Ultimately, the cooled and condensed refrigerant returns to the indoor unit, where it goes through an expansion valve. The expansion valve decreases the pressure on the refrigerant, making it very cold. This cold refrigerant circulates through the evaporator coil once again, absorbing heat from the indoor air and repeating the cooling cycle.
As this continuous cycle repeats, the split system air conditioner gradually lowers the temperature of the room, bringing comfort to occupants. The heat captured from indoors is efficiently expelled outside, allowing for a pleasant and cool environment indoors.
In summary, a split system air conditioner cools the indoor air by transferring heat from the room to the outdoor unit. It achieves this through a process involving the evaporation and condensation of a refrigerant. By effectively managing the temperature exchange, split system air conditioners provide reliable and efficient cooling for indoor spaces.
Components of a Split System Air Conditioner
A split system air conditioner consists of several key components that work together to provide cool air and maintain a comfortable indoor environment. Understanding these components can help you troubleshoot issues and make informed decisions about your air conditioner. Let’s take a closer look at the main components of a split system air conditioner:
1. Indoor Unit
The indoor unit of a split system air conditioner is usually installed inside the room that needs to be cooled. It contains two important components:
- Evaporator Coil: The evaporator coil is responsible for transferring heat from the indoor air to the refrigerant. It is made up of a network of tubing that carries the refrigerant and a set of fins that enhance heat transfer. As warm air passes over the coil, the refrigerant absorbs the heat, cooling the air in the process.
- Air Handler: The air handler is the fan that circulates the cooled air throughout the room. It draws in warm air from the room, passes it over the evaporator coil to cool it, and then blows the cooled air back into the room. The air handler also houses the filter that removes dust and other particles from the air before it is recirculated.
The indoor unit is typically compact and designed to blend in with the aesthetics of the room. It is connected to the outdoor unit by refrigerant lines, electrical wiring, and a condensate drain line.
Understanding the Refrigeration Cycle in Split AC
A split system air conditioner works by using a refrigeration cycle to cool the air in your home. This cycle involves four main components: the compressor, condenser, expansion valve, and evaporator. Let’s take a closer look at how each of these components work together to create the desired cooling effect.
1. Compressor
The compressor is the heart of the split system air conditioner. Its main function is to compress the refrigerant gas, increasing its pressure and temperature. This compressed gas is then sent to the condenser for further processing.
2. Condenser
The condenser is located in the outdoor unit of the split system air conditioner. It is responsible for releasing the heat from the compressed refrigerant gas. As the high-pressure gas flows through the condenser coils, it loses heat to the surrounding environment, causing it to condense into a high-pressure liquid.
This heat release process is aided by a fan blowing outside air over the condenser coils. The outdoor unit is designed to be located in an open area with good airflow to maximize the efficiency of this heat exchange.
3. Expansion Valve
The high-pressure liquid refrigerant then moves into the expansion valve. This valve acts as a restriction, causing the pressure of the refrigerant to drop suddenly. As a result, the refrigerant changes from a high-pressure liquid to a low-pressure liquid with a mixture of liquid and gas.
This sudden pressure drop also causes a temperature drop, making the refrigerant cooler. This cooled liquid-gas mixture then moves into the evaporator for the next stage of the cycle.
4. Evaporator
The evaporator is located in the indoor unit of the split system air conditioner, typically mounted on a wall or ceiling. Inside the evaporator, the cooled refrigerant absorbs the heat from the air in your home, causing it to evaporate into a low-pressure gas once again.
As the refrigerant evaporates, it takes in heat from the surrounding air, cooling it in the process. A fan blows this cooled air back into your home, providing the desired cooling effect. The now low-pressure gas returns to the compressor to start the cycle again.
Overall, the refrigeration cycle in a split system air conditioner is a continuous process that allows the system to cool your home effectively. By understanding how each component works and their role in the cycle, you can better appreciate the functionality of your split AC unit.
Benefits of Using a Split System Air Conditioner
3. Energy Efficiency
One of the significant benefits of using a split system air conditioner is its energy efficiency. Unlike traditional air conditioning systems that cool the entire house, a split system allows you to cool specific rooms or areas, reducing energy consumption. This targeted cooling approach ensures that you only use energy where it is needed, resulting in lower energy bills.
- The ability to cool specific areas means you can avoid wasting energy on empty rooms or areas that don’t require cooling. For example, if you spend most of your time in the living room, you can cool only that area rather than the entire house.
- Split system air conditioners are designed with advanced technology that enhances their energy efficiency. For example, most models come with inverter technology, which allows the compressor to adjust its speed according to the cooling needs. This means the system can operate at a lower capacity when the desired temperature is reached, saving energy.
- Additionally, split system air conditioners often have programmable thermostats that allow you to set temperature schedules. This feature enables you to cool your home only when needed, reducing energy consumption during periods when you are away or asleep.
By investing in a split system air conditioner, you can enjoy the benefits of energy efficiency while keeping your home cool and comfortable.

It is important to turn off the power before making any electrical connections and to check the voltage requirements of the split system air conditioner to ensure compatibility with the electrical supply.
5. Testing and Commissioning
After completing the installation, it is essential to test and commission the split system air conditioner. This involves checking the functionality of each component, such as the indoor and outdoor units, the thermostat, and the remote control.
It is also necessary to verify that the refrigerant levels are correct and that there are no leaks in the system. This can be done by conducting pressure and leak tests.
Once all the checks have been successfully completed, the split system air conditioner is ready for use, providing efficient cooling or heating to your space.
Common Issues and Troubleshooting Tips for Split AC
5. Leaking Water
One of the common issues that can occur with a split system air conditioner is water leaking. This can be caused by a few different factors, but the most common cause is a clogged condensate drain line. The condensate drain line is responsible for removing the moisture that is created when the air conditioner cools the air. Over time, dust, dirt, and other debris can accumulate in the drain line, causing it to become clogged.
If you notice water leaking from your split AC, try the following troubleshooting tips:
- Check the condensate drain line for any visible clogs. If you see a blockage, you can try using a wet/dry vacuum or a pipe cleaner to remove the debris.
- If the clog is more stubborn, you may need to use a chemical drain cleaner specifically designed for use in air conditioners. Follow the instructions on the cleaner carefully and make sure to flush the line with water after using the cleaner.
- Inspect the condensate drain pan for any cracks or damage. If there are any issues with the pan, it may need to be replaced.
- Ensure that the condensate drain line is properly sloped. The line should be angled downward to allow for proper drainage. If the line is not sloped correctly, you may need to adjust it to ensure proper drainage.
- Regularly clean and maintain the air filter. A dirty or clogged air filter can impact the airflow and cause the cooling coil to freeze, leading to water leakage.

Energy Efficiency Ratings of Split System Air Conditioners
When it comes to split system air conditioners, energy efficiency ratings play a crucial role in determining the overall performance and cost-effectiveness of the system. These ratings are standardized measurements that help consumers compare different models and make an informed decision. Understanding the energy efficiency ratings can help you choose a split system air conditioner that not only keeps your environment comfortable but also saves money on energy bills.
Split system air conditioners are rated based on two main criteria: Seasonal Energy Efficiency Ratio (SEER) and Energy Efficiency Ratio (EER). These ratings provide important information about how efficiently the air conditioner uses electricity to cool a space.
The Seasonal Energy Efficiency Ratio (SEER) is the most common rating used for split system air conditioners. SEER measures the cooling output of the system divided by the amount of energy it consumes during a typical cooling season. The higher the SEER rating, the more energy efficient the system is. In general, a higher SEER rating translates to lower energy consumption and lower operating costs.
For example, if you have a split system air conditioner with a SEER rating of 16, it means that the system produces 16 units of cooling output for every unit of energy consumed. On the other hand, a system with a SEER rating of 10 will produce 10 units of cooling output for the same amount of energy consumption. This means that the system with a higher SEER rating will cool your space more efficiently, resulting in lower energy bills.
Energy Efficiency Ratio (EER)
In addition to SEER, the Energy Efficiency Ratio (EER) is another rating that measures the efficiency of a split system air conditioner. EER is calculated by dividing the cooling capacity of the system in British Thermal Units (BTUs) per hour by the amount of energy it consumes in watts. Unlike SEER, the EER rating is based on a constant indoor temperature and does not account for temperature fluctuations throughout the cooling season.
A higher EER rating indicates a more energy-efficient air conditioner, as it can provide greater cooling output for the same amount of energy consumption. However, the EER rating is not as commonly used as the SEER rating for split system air conditioners.
When considering the energy efficiency ratings of split system air conditioners, it’s important to keep in mind that higher-rated systems may have a higher upfront cost. However, the long-term energy savings can often outweigh the initial investment. Additionally, choosing a system with a high energy efficiency rating is not only beneficial for your wallet but also for the environment, as it reduces greenhouse gas emissions and overall energy consumption.
