How Does a Portable Air Conditioner Work?

In this article, we will discuss the mechanisms of a portable air conditioner and understand how portable air conditioners work and why it is preferable to use one.

Portable air conditioners are responsible for pulling hot air out and removing humidity from a closed room or area.

They provide the same cooling power without any requirement for permanent installation and are easy to move from one place to another.

They are a multi-skilled and convenient way to cool down a room.

There are three principle components of a portable air conditioner:

  1. Refrigerant: used for cooling down the air
  2. Compressor: used for compressing the refrigerant
  3. Fan: used to move the air

Portable ACs have two major types of systems. Single Hoes and Double Hoes. The following are the steps explaining the function of a portable air conditioner.


During the cooling down procedure, the first step is to vent the hot air.

The exhaust hose is attached to the back of the portable AC and it is connected to the window adapter.

The adapter is inserted into a window or a door which allows the heat to escape from the room.

Air Intake

After the ventilation system is set up, the fan sucks the hot air from the room.

Through the front section, the cool air is pulled into the portable air conditioner and passes over a cold evaporator coil.

Cooling Down

An evaporator coil that contains refrigerant (that absorbs heat from the air) allows warm air to pass over it. Air is cooled down and the moisture is extracted.

Refrigerant fluids evaporate and turns into gas. The cool air is circulated back to the room and the excess moisture is removed from the room to prevent uncomfortable air.

Refrigerant Compressing

The compressor compresses the refrigerant gas which makes it hot. The condenser cools down the hot refrigerant and it turns back to liquid.

The liquid is sent back to the refrigerator and the cycle repeats. The heat produced during this process is vented out of the exhaust fan.

Automatic Shut off

Some portable air conditioners possess an automatic shut-off feature which helps in turning the unit off when the required temperature is reached. It helps in preventing damage to the system and works efficiently.

Why Should You Prefer a Portable Air Conditioner?

There are several reasons why one should consider using portable air conditioners.

  • Easy to install

Unlike other ACs, they do not require heavy equipment and space for installation.

It does not require any professional technicians to install it. Because of their reasonable size and weight, they can be moved from one place to another.

  • Less Expensive

A portable air conditioner is better than other air conditioners in terms of price and cost. It also helps in reducing electricity bills in comparison to other air conditioners.

  • Multifunctional

It is very effective for you if you live in a region where the weather changes to its extremes. It has a system of cooling and warming according to your needs.

  • Better Air Quality

It has better indoor air quality. Air is filtered through the filters of portable air conditioners. Dust particles and microorganisms are removed through the air of a portable air conditioner.


Portable Air conditioners work efficiently to improve air quality inside the room where they are easy to install.

They are a convenient and cost-friendly way to cool down your room or house. They are versatile, environment friendly, and help in keeping the atmosphere cool or warm without any permanent installation.

They help in improving the indoor air quality of a room by dehumidifying the air. To recapitulate, investing in portable air conditioners is effective and cost-friendly.
