How does an Air Conditioner Works At Home

Before outlining the step by step procedures on how air Conditioners works you need to at least know the meaning of an “Air Conditioner”

What is an Air Conditioner?

Air conditioner is a machine that is used to remove heat from a surrounding, thereby replacing it with cool and vise versa (that is, from cool to back to heat).

It is a device that can be installed in homes premises, as well as in an enclosed space. It is a team for the comfort of people.

The air conditioner is used to cool the environment in hot weather while functions to warm the environment in cold weather.

According to Wikipedia, Air conditioning is the process of removing heat and moisture from the

interior of an occupied space to improve the comfort of occupants.

Types of Air Conditioner

There are six common types of air conditioner, and they will be listed below…

Central Air Conditioning:

central aircondition

As the name goes “central”. its a type that start its cooling from the center then transferred by one or more fans to other places in the home.

Note, cool air is achieved when there is compression of the refrigerant gas.

Window Type Air Condition:

windows aircondition

As its name goes ‘Window” it is installed into window of a room with the aim of achieving cooling.

It is the simplest form of air conditioning. when the fans blows the evaporator coil, the interior air is cooled.

on the other hands when the fan blows outside air over the condenser, the exterior air draws heats from the interior then discharge to the environment.

Ductless/ Split Air Conditioners:

split unit Air Conditioner

This Ac produces cool air almost the same way with Central AC, just that this one does not use duct. 

They suck in warm air from your home, absorb the heat and moisture from that air, then dump the heat/moisture outside. It is mostly used in Europe and Southeast Asia. .

Portable Air Conditioner:

portable Air Conditioner

This type of air conditioner is easy to carry about.

It does not really require permanent installation like the window and central type of air conditioner.

Stagnant air is pulled from inside the room, air is been cooled to circulate the room with help of the motor inside the ac unit.

Geothermal Air Conditioning:

geothermal Air Conditioner

This type uses the ground as heat sink, so it removes heat from the house and deposits it in the earth,

Instead of of drawing heat from the earth with its loops. Geothermal is made up of ground loops and a heat pump

to provide both heating and cooling, which saves you money, space, and so many headaches.

Benefits of Ac in Our Homes

  • It helps to removed heat in the Surroundings.
  • Due to its cooling nature, it improves work performance.
  • Ac can also reduce possibilities of Asthma attack.
  • Protect your properties: hot weather increase.
  • It gives sound sleep.
  • An air conditioner can also reduce insect and Parasites in houses.
  • It increases comfort.

Disadvantages of Air Conditioner

As we know, anything that has advantage must surely have disadvantage, and they will be listed below;..

  • It might affect individuals respiratory system when there is change in humidity and temperature.
  • when an air conditioner is frequently used it can dry the skin
  • An air condition can also cause noise pollution.
  • It requires regular maintenance thereby, consuming your time.

How it (AC) Works In General

  1. Warm air from the room is sucked in through a grille at the base of the machine
  2. The air flows over some chiller pipes through which a coolant fluid is circulating. Hence making this part of the machine works just like the chiller cabinet in a refrigerator. It cools down the incoming air and a dehumidifier removes any excess moisture.
  3. The air then flows over a heating element (similar to the one in a fan heater). On a cold day, this part of the unit may be turned right up so the HVAC works as a heater.
  4. A fan at the top blasts the air back through another grille into the room. If the heating element is turned down, the air re-entering the room is much cooler, so the room gradually cools down.
  5. Meanwhile, coolant (a volatile liquid that evaporates easily) flows through the chiller pipes. As it does so, it picks up heat from the air blowing past the pipes and evaporates, turning from a cool liquid into a hotter gas. It carries this heat from inside the room to the outside of the building, where it gives up its heat to the outside air. How? Just like in a refrigerator, the coolant flows through a compressor unit and some condensing pipes, which turn it back into a cool liquid ready to cycle round the loop again.
  6. What happens to the heat? In the unit outside the building, there are lots of metal plates that dissipate the heat to the atmosphere. An electric fan blows air past them to accelerate the process.
  7. Over time, the heat inside the building gradually pumps away into the outside air.

Component of an Air Conditioner

Generally an air conditioner comprises of Four(4) main component, They are….

1. The Condenser

Air Conditioner: Condenser – The Palm

A condenser is a device or unit used to condense a gaseous substance into a liquid state through cooling. Condenser helps to convert vapor to liquid. And there are three types of condensers namely, Air-cooled, Evaporator, and Water-cooled condensers.

2. The Compressor

Air Conditioner: Atlas Copco Compressor and AC 21 - 10 E Kompre Automan AC, 1 ...

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

An air compressor is a specific type of gas compressor. Compressors are similar to pumps: both increase the

pressure on a fluid and both can transport the fluid through a pipe. It is responsible for the moving of the

refrigerant between the Condenser and Evaporator coils, thereby ensuring that the refrigerant converts gas to liquid when needed.

3. The Evaporator

An evaporator is a device in a process used to turn the liquid form of a

chemical substance such as water into its gaseous-form/vapor. It is just the opposite of condenser, in Air conditioner the

an evaporator the refrigerant liquid is converted to gas, thereby absorbing heat from air in the compartment,  

its heat content makes it much cooler than the fan air flowing around it as the evaporator pressure is been reduced.

4. The Expansion Valve

Air Conditioner: The Expansion Valve

A thermal expansion valve or thermostatic expansion valve (often abbreviated as TEV, TXV, or TX valve) is a component in refrigeration and

air conditioning systems that controls the amount of refrigerant released into the evaporator thereby keeping

super-heat, that is, the difference between the current refrigerant. In air conditioner, expansion valve changes a state

from liquid to gas/vapor by removing pressure from the liquid.

Is it better to run AC all day or just at night?

People do ask “is it better to leave your Ac all day or just night”. we are going to explain how to use your Ac.

Jennifer Thorne Amann once said “Air-conditioning systems run most efficiently when they’re running at full speed”,

If you have noticed your Air conditioner starts making noise when initially cooling a space down from 75 – 80 degrees,

so it requires more energy running all day with less speed. According to American Council for Energy-Efficient Economy (ACEEE),

Air conditioner uses 3% – 5% less energy for every degree you raise the thermostat.

So it is advised to leave your thermostat set at 75 degree or more when you are out.

How do I make my air conditioner colder?

When the day is very sunny you are to increase the thermostat to cool the inside (your house).

This can also be proven by turning your thermostat on the highest on a hotterday and lowering it on a warmer day.

For instance on a very hot day you observe that there is much heat even inside your house,

so to reduce the heat you will have to increase your thermostat in other to feel colder inside
