How does air conditioning work?

Air conditioning units work by removing the warm air from inside your home and pumping it outside, while releasing the cool air back into the room, reducing the temperature. When liquid becomes gas, it absorbs heat, and in principle, this is how they function.

Air conditioning systems work very much in the same way as your standard refrigerator, in that heat is absorbed inside the system and then removed from the room.

Here’s the process:

• Firstly, the warm air from the room is drawn into the system.

• This air flows over the cold evaporator pipes inside, which cools the air down while a dehumidifier removes excess moisture.

• Meanwhile, the coolant flowing through the chiller pipes absorbs the heat from the air blowing past and evaporates, turning from a cool liquid to a warm gas.

• This warm air is pumped outside while the coolant flows through a compressor unit and a condenser, which turn it back into a cool liquid.

• Cold air is then re-circulated into the room where it mixes with the existing air and reduces the temperature and humidity.

Inside a unit, there are a number of different components that manipulate the state, pressure, and temperature of the refrigerant, allowing the unit to do its job and cool the room.

 

The health benefits of air conditioning.

• Air conditioners contain a filter that removes particles and allergens, such as pollen and dust, from circulating into the air, helping to clean the air you breathe inside your rooms. Similarly, they also act as dehumidifiers. This is because conditioners draw moisture from the air within a room, reducing the humidity.

• When the temperature increases, you’re more at risk of heat stroke. With an air conditioning system in place, you’ll reduce the risk of heat stroke and other heat-related illnesses.

• Surprisingly, air conditioning helps to reduce the risk of dehydration. Lower temperatures in a room mean that you’ll sweat less. When you sweat, you’re actually losing a lot of water from your body. It’s important to keep hydrated, of course, but an air conditioning system will help to combat possible dehydration.

• With more regulated temperatures during the night-time, you’ll be able to sleep much better. Keeping bedrooms cool ensures you’re much more comfortable while you’re sleeping, which in turn will make you better rested for the day ahead.

• Cleaner air from an air conditioning system means that there is a reduced possibility of asthma attacks with sufferers of the condition. However, it’s also important to change the filter when needed to further reduce that risk.
