Understanding the Basics: How Does Air Conditioning Work?

If you want to improve your property’s comfort and air quality, you may be considering investing in an air conditioning system. Most of us know what AC solutions do, but have you ever wondered how these systems actually work? In this blog post, we'll break down the basics of air conditioning, giving you a clearer understanding of the technology that keeps you cool during hot summers and provides efficient heating during our cold winters.

The Fundamental Principles of Air Conditioning

Before delving into the inner workings of air conditioning, it's essential to grasp the fundamental principles behind it. Air conditioning systems are designed to regulate temperature, humidity and air quality in indoor spaces. They achieve this through a remarkable process known as the refrigeration cycle.


The Refrigeration Cycle

The heart of any air conditioning system is the refrigeration cycle. This cycle consists of four main components: a compressor, a condenser, an evaporator, and an expansion valve. Here's how it all comes together:


Compression: The cycle begins when the compressor compresses a low-pressure, low-temperature gas known as refrigerant. This compression increases the temperature and pressure of the refrigerant.


Condensation: The hot, pressurised refrigerant is then sent to the condenser coil, where it releases heat and transforms into a high-pressure liquid.


Expansion: Next, the high-pressure liquid refrigerant flows through an expansion valve, where it suddenly expands and becomes a low-pressure, low-temperature mixture.


Evaporation: This low-pressure refrigerant is now directed to the evaporator coil. As warm air from inside your home is blown over the coil, the refrigerant absorbs heat, turning it back into a low-pressure gas.


Heat Transfer and Regulation

Air conditioning systems rely on the principle that heat naturally moves from warmer areas to cooler ones. During the evaporator phase, the air's heat is absorbed by the refrigerant, causing the air to cool down. The now-cooled air is then circulated back into your living space.


Humidity Control

In addition to cooling, air conditioning systems also regulate humidity. When warm air passes over the evaporator coil and loses heat, moisture in the air condenses on the coil's surface. This process removes excess humidity from the air, making your indoor environment more comfortable.


Achieving the Desired Temperature

The air conditioning system continually repeats the refrigeration cycle, maintaining your desired indoor temperature and humidity levels. Modern systems have thermostats that allow you to set the temperature you want, ensuring a consistent and comfortable environment.


Regular Maintenance

To keep your air conditioning system running smoothly and efficiently, it's crucial to schedule regular maintenance. Here at Complete Cooling Services, we offer a range of air conditioning maintenance services to help keep your AC solution operating as it should. We can carry out routine inspections of your system’s components, check refrigerant levels, and ensure all parts are in good working order. Should your air conditioning ever stop performing at its best, we can also run diagnostic checks and carry out any necessary repairs in order to get it back up and running.


Understanding the basics of how air conditioning works can help you make an informed decision when purchasing and maintaining an AC solution.
