Install an HVAC and Keep Cool

The Australian summer can be super hot. If you live in Australia, you will want to make sure you can stay cool during the intense heat. I came to realise how important HVAC systems are when I moved into an apartment which didn't have HVAC. It was OK in the winter, but by the summer, it was terrible. I called in an HVAC contractor and asked them to install a new system. It was amazing what a difference it made. The contractor also gave me some advice about how to maintain the system. I hope this blog is useful to you.

Want to Know How an Air Conditioner Works?


Many people have air conditioning systems installed in their homes with their sole purpose being to cool summer temperatures. On hot days, they switch on the A/C for cool air to circulate inside the home while replacing the hot air. But have you ever wondered about how the hot/cool air exchange takes place in your air conditioner?

Keep reading on if you want to learn about the various critical components of an air conditioner, and how each component works to ensure you get cooling service in your home.

The Compressor

Your heart is a vital organ. It keeps you alive by receiving blood from all over your body, pumping it to the lungs, and then circulating it around the body. You can compare your A/C compressor to the heart and the refrigerant to the blood that is circulated around the body.

The compressor is the component that circulates refrigerant between the condenser coil and the evaporator coil, making it possible to cool the air up to the desired room temperatures. Without it, refrigerant wouldn't be pumped where it is needed. Refrigerant is the all-important working fluid that acts as a medium to facilitate the hot/cool air exchange that takes place in your air conditioner.

The Condenser Coil

It is found in the outdoor unit. Its work is to draw heat from hot refrigerant gas and convert the gas into liquid state. The cool, liquid refrigerant then flows into the evaporating coil while the absorbed heat is allowed to escape outside.

The Evaporator Coil

It is found in the unit installed within the home. The indoor unit has a blower fan that draws hot indoor air and pulls it to the evaporating coil. Remember, the evaporator coil has cool, liquid refrigerant inside it. So, when hot air passes over it, the air gets cooled by the cool refrigerant.  The cooled air is then released back to the room, thanks to the pumping action of the compressor.

With time, the cool refrigerant in the evaporating coil becomes warm since it was absorbing heat from the hot air. If the refrigerant continues to stay there, then the hot air coming in from the house room will not be cooled, it will end up being returned back to the room while still hot.

To keep this from happening, the compressor pumps the warm refrigerant back to the condenser where it is cooled. This cycle repeats itself until the desired room temperatures are achieved.

With that, the mystery behind the working of an A/C is hopefully solved. If you have any further questions you need answered, feel free to talk to an HVAC expert any time you like.
