How to choose an air conditioner for a bedroom?


In the quest for a good night’s sleep, the importance of a comfortable environment cannot be overstated. Factors such as temperature and humidity play pivotal roles in ensuring restful slumber. Modern air conditioners, as of 2023, have transcended their traditional roles as mere cooling devices. They now regulate humidity, filter pollutants, and maintain consistent bedroom temperatures, making the choice of the right unit essential for optimal rest.

Understanding the Basics of Air Conditioners

Let’s take a look at the most popular types of air conditioners:

Types of Air Conditioners

  • Portable Units: Easy-to-move units suitable for cooling different rooms at different times. Portable air conditioners are also quite affordable – prices vary from 200 USD to 500 USD;
  • Window Units: Compact air conditioners that fit into windows, suitable for cooling single rooms. Although these devices are quite expensive (over 400 dollars), their efficiency may not be satisfying;
  • Split or Ductless Units: Consists of two parts, an indoor unit and an outdoor compressor, efficient for larger spaces without ductwork. Even though such devices are quite costly, it’s definitely the most reasonable solution for your bedroom (as well as for entire house).

How Air Conditioners Work?

how does an air conditioner work?

Air conditioners function based on the principles of thermodynamics, specifically the movement of heat from one area to another. Here’s a basic overview of how this process works:

  1. Refrigerant Cycle: At the heart of every air conditioner is a refrigerant, a special fluid that changes states between liquid and gas. This refrigerant circulates through a cycle of evaporation and condensation, driven by a compressor and other components.
  2. Cooling Process:
    • Evaporation: Inside the unit, the refrigerant is allowed to expand and turn into a low-temperature gas. As room air is passed over this cold coil, the air loses its heat to the refrigerant, thereby cooling the air.
    • Condensation: The refrigerant, now carrying the absorbed heat, is compressed and pumped to the outdoor unit. Here, the heat is released, and the refrigerant cools down, turning back into a liquid. The cycle then repeats.
  3. Air Circulation: Fans play a crucial role in circulating air. An indoor fan blows room air over the cold evaporator coil, cooling it down, while an outdoor fan expels the absorbed heat outside.
  4. Thermostat Regulation: Modern air conditioners come with thermostats and sensors that monitor the room’s temperature. When the desired temperature is reached, the air conditioner will cycle off. If the room gets warmer, it will cycle on again.
  5. Air Filtration: In addition to cooling, air conditioners often contain filters that remove airborne particles, improving indoor air quality.
  6. Dehumidification: Air conditioners also function as dehumidifiers. As air passes over the cold evaporator coils, moisture from the air condenses on these coils, reducing the humidity level in the room.

To sum up, an air conditioner cools your room not by adding cold air, but by removing heat from the room and expelling it outside. This cycle continues until the room reaches the temperature set on the thermostat. The basics of working of these devices are the same as for the fridge.
