How your Indoor AC Unit Works

As fellow Dubai residents, we know we don’t need to go into a lot of detail about the importance of ACs in our lives. The lifeblood of our everyday home life, our air conditioning units work day and night to stave off the monstrous heat of the sizzling city and regulate our body temperatures. A clean, well-functioning ac keeps us fresh and happy, especially during peak Dubai summer. 

But for those looking to understand the marvels of technology and human brilliance that collaborate to deliver this divine machine, here is your starting point. A basic meet and greet with the unsung heroes of Dubai life. 

As you may know, the heating, ventilation, and air conditioning unit (HVAC) is also affectionately known as the AC. The average air conditioner can be divided into two halves to simplify our learning. The indoor and outdoor AC. This post will focus on an HVAC unit’s indoor parts and an explanation of how they work in tandem with the outdoor unit to keep our homes and lives cool and fresh. 

What is the indoor part of an AC?

The average indoor half of a unit is the home-facing part that you see every day and interact with inside your home. This includes your thermostat, the vents, filters, evaporator coil, indoor motor and ducts. This part, as with the rest of your air conditioner, requires keen maintenance and routine checks. 

The indoor component of the HVAC is the one that expels cool air into your central living space and ensures that it is devoid of dust and other foreign particles. You can also adjust and set the temperature and fan speed to your liking through the thermostat, but you knew that.

Now let’s take a closer look at the indoor components of your air conditioner.

Main Indoor Air Conditioning Parts

What is a refrigerant?

The refrigerant is the key ingredient in your AC’s cooling process. One could say that it’s the key ingredient since the whole system is built around the refrigerant’s cooling properties. Its role is to create the cool air that gets distributed around your home through your unit. Your system wouldn’t work without it. You’ll find it being used in different refrigeration appliances, too.

The cooling solution makes its way through your system as different parts work together to keep your home chilled on a warm day. Air conditioning units reach an optimal pressure at which they operate, this may vary depending on unit type.  We recommend figuring out your AC’s limit, to stay aware in case of problems.

There’s no need for drumrolls, but let us now move to the main elements of your indoor cooling system. 

Filters

The first thing we can tell you about filters is that not all AC units have them. But they should. Your filter is the last and final stopper for all the little dust and debris particles that can build up over time inside your AC. Essential to our everyday health, they help keep our lungs healthy by clearing the air of these tiny particles and preventing them from entering our bodies. It’s also the easiest part to buy and reinsert yourself if you have a touch of DIY about yourself. For uncompromised air quality, your AC filter is the first and most basic step to enact. A point to be noted is that the filters inside your unit have to be replaced and/or cleaned regularly to prevent allergens and dust from piling up on it over time. This accomplishes two things. The obvious; better air. The subtle; it helps keep your DEWA bills on the low side by not hindering the airflow. 

The Evaporator Coil

As we mentioned before, the indoor and outdoor units of your AC work together as a team to cool your space down. Your indoor evaporator coil connects to the condenser coil in your outdoor air conditioning unit. Together, they work to help the refrigerant absorb heat indoors, and release it outdoors. By the decree of science and engineering, evaporator coils are made from metals that conduct heat best; steel and copper. The refrigerant transforms from liquid to gas when it reaches the condenser coil. It absorbs heat from your space and transfers it to the condenser coil outside in this form, and repeats this in a cycle. To ensure the smooth functioning of the evaporator coil, it needs to be kept clean. A grime-filled coil not only works inefficiently but also ends up using a higher amount of energy, with the additional risk of a breakdown and leaks in the future. 

Ducts

You might have seen pictures of your AC ducts- the metallic silver tubes that carry cool air into your home. A passage built exclusively for air to travel through, it carries chilled air in our out of our rooms. Two ducts work on that process; one to suction warm air out and another sends the soothing cool air our way. A poorly maintained duct can harbor sand, dead insects, dust, and even mold. If you or your family suffers from low-level perpetual respiratory conditions, it would be advisable to ensure that your air conditioner isn’t the cause of it by getting it professionally looked over.

Thermostat

We’re not going to go into a lot of detail on this one, but the thermostat enables you to adjust and set your temperature requirements. Some air conditioners also have thermostats that can be adjusted remotely. If you’re anything like us, you get a small thrill out of playing the ‘let’s save energy’ game by adjusting the temperature in different rooms according to your family’s needs. If not, try it! It helps you pay attention to your AC’s functioning on a deeper level while valiantly doing your part for the planet!
