How do portable air conditioners work?

A portable air conditioner works in a similar way to a wall-mounted split, but it concentrates the indoor and outdoor unit in the same device. Its operation is very simple and basically consists of:

  1. Extract hot air from the environment, which enters the appliance through slots
  2. Cool it thanks to tubes with refrigerant inside
  3. Expel the already cooled air into the room
  4. Blow the uncooled air outside the house, so they should be placed next to a window or balcony

Thus, the sensation of freshness is practically immediate nothing else connects the device. In addition, thanks to its temperature sensor, it can be configured to reach a certain temperature in the room and keep it constant.

Types of portable air conditioner

There are different types of portable air conditionerbeing the most common:

  • Single duct or monoblock monotube air conditioning. It consists of a flexible tube that expels the hot air generated in the condensation and that is placed in the window. It is economical and it is the most common, although not the most effective since by taking in the air from the room itself, it is also expelling part of the already cooled air.
  • Double duct or double pipe monoblock air conditioner. It consists of two flexible tubes: one of them takes in the air from the street to condense it and generate cold air, and the other expels the hot air from the condensation. It is more expensive, but more efficient and low consumption.
  • Equipment with outdoor unit or split portable air conditioner. The condensing unit is separate and is placed outside, communicating with the indoor unit through a tube placed in the window. It is the most expensive, but also the lightest and quietest, since the compressor is outside and the air conditioner is inside.

On the other hand, we must differentiate between a portable air conditioner and a portable air conditioner. The second have a similar operation to that of a fan and do not have any connection tube with the outside. Basically, it collects air from the room and cools it by passing it through a compartment with cold water or ice.

Although an air conditioner is light and cheap, it only manages to lower the temperature of the room by a few degrees. In addition, it increases the level of humidity and they are not highly recommended in climates that are already humid.
