Your air conditioning unit is filled with different components, each as important as the next, to ensure your system runs as efficiently and effectively as possible. A key ingredient to the smooth running of your system is refrigerant. To put it simply, refrigerant helps create the cool air that circulates your home through your air conditioner. Without it, your system wouldn’t work.
What is air con refrigerant? How can you spot a refrigerant leak? This guide will explain why refrigerant plays a crucial part in the home air conditioning system, how to check your refrigerant levels and also what to do if you ever spot a refrigerant leak.
The refrigerant used in air conditioning systems is usually found in either a gas or liquid form. It is a crucial component for a working system as it absorbs heat from the environment and converts it into a cool air flow when combined with the other components of your air conditioner.
There are many different types of refrigerant used in a variety of refrigeration products, but for air conditioning systems, there are two main types; R-22 or more commonly known as Freon, and R410A, also known as Puron. Puron is said to be much more environmentally friendly than Freon, and is the most popular choice for modern AC systems.
The type of refrigerant in air conditioning will depend on how old a system is. Manufacturers of air conditioning systems are actively looking to replace Freon with Puron entirely by 2020. Not only will it be kinder to the environment, but it will also have the same effective cooling properties. However, the only downfall is that Puron cannot be used with Freon systems, meaning that eventually, you’ll have to replace an old system.
Freon has been used as the main refrigerant in central air conditioning systems for many years. Its use has been shown to be harmful to the environment, so, as a result, has been banned from being manufactured.
Aside from being the modern choice for air conditioning systems today, there are many benefits of switching to a Puron refrigerant, including the following:
Air conditioner refrigerant is the crucial part of the air cooling process and is situated inside the system’s copper coils. The job of the refrigerant is to travel through the system to the different parts of the air conditioner, changing from a low-pressure gas to a high-pressure liquid. As it does so, it absorbs heat and then releases it along its journey, helping to bring cool air to the rooms of your home.
When the refrigerant travels to the outdoor unit, it releases heat through condensation, which then forces it to cool down. When it reaches the indoor unit, the refrigerant causes evaporation because of the reduced temperature coming into contact with the warmer air. The process repeats itself which constantly blows out a steady stream of cool air, blown into a room by fans and vents.
The refrigerant cycle in air conditioning is continuous and the refrigerant itself will always stay at the same level all the way through your system’s life. However, this is only upon the assumption that your system doesn’t encounter a leak.
Freon leaks in particular can be harmful, not only to the environment, but to anyone who comes into contact with the substance. There are a number of signs you should look out for, some more obvious than others:
It’s very important to fix a refrigerant leak as soon as it is confirmed. If you’re not sure, you should get in touch with your air conditioning manufacturer and have an engineer run a series of tests to check for a leak. If your system runs on Freon, then it is even more important to get in touch with a qualified engineer; exposure to the refrigerant chemicals can be very dangerous.
Air conditioner refrigerant is an essential part of the running of an air conditioning system. It’s needed to ensure you receive cool air to the right areas of your home and, by choosing the right type, it’ll be cheaper for you and kinder to the environment.
