The outdoor unit, usually installed outside the building, houses the compressor and condenser, which are essential for the air conditioning process.

When it comes to cooling or heating your home, a split system air conditioner offers a versatile and efficient solution. But what are the key components that make up this system? Let's take a closer look.

Key Components of a Split System Air Conditioner

A split system air conditioner comprises several key components that work together to provide efficient cooling or heating:

• Compressor: The compressor is like the heart of the air conditioning system. It plays a vital role in circulating the refrigerant between the indoor and outdoor units. By compressing the refrigerant gas, it increases its temperature, setting the stage for the cooling process.
• Condenser: The condenser, located in the outdoor unit, is responsible for dissipating heat from the compressed refrigerant. It helps convert the high-pressure gas into a high-pressure liquid, preparing it for the next stage of the cooling cycle.
• Evaporator: The evaporator, situated in the indoor unit, is where the magic happens. It absorbs heat from the room and cools the air by evaporating the refrigerant. This cooled air is then circulated back into the room, creating a comfortable environment.
• Air Handler: The air handler, located inside the indoor unit, plays a crucial role in distributing the cooled or heated air throughout the room. It ensures that every corner of the space receives the desired temperature, providing optimal comfort.

How Does a Split System Air Conditioner Work?

Now that we understand the key components, let's delve into the inner workings of a split system air conditioner. Here is a step-by-step overview of how the system operates:

1. The compressor in the outdoor unit kicks into action, pressurizing and heating the refrigerant gas.
2. The high-pressure refrigerant gas flows through copper tubing to the indoor unit, ready to cool or heat the space.
3. In the indoor unit, the refrigerant passes through an expansion valve, reducing its pressure and preparing it for the cooling process.
4. As the refrigerant expands, it absorbs heat from the room, cooling the air and creating a refreshing environment.
5. The air handler, located inside the indoor unit, blows this cooled air into the room, ensuring that every corner is filled with comfort.
6. The refrigerant, now in a gaseous state again, flows back to the outdoor unit, where the process repeats to maintain the desired temperature.

With its efficient operation and versatile design, a split system air conditioner is a reliable choice for cooling or heating individual spaces. Whether you're looking to create a comfortable living room or a cozy bedroom, this system has got you covered.
