The principle is the same as for a refrigerator; the physical rule that says that liquid that evaporates absorbs heat. There is a liquid refrigerant that’s led into an evaporation system. Low pressure makes the refrigerant liquid evaporate into a gas that cools air-conditioning flanges. The cold from the flanges is then blown out into the room by a fan. Heat is also generated from this process and has to be dissolved.
It depends on the size of the area being cooled and how cold you want it. For an area of 45 square metres, the cost is usually around 7 pence an hour, if you cool it down from approximately 27 degrees to around 21 degrees. For an area of 60 square metres, the cost is around one 8 pence an hour, and for 80 square metres, it is just under 17 pence an hour. However, this can vary as the price of electricity varies; this is just an indication of the cost. Cooling a bedroom on a hot summer night costs about 70 pence.
There are fixed and portable air conditioners. In both cases, the heat generated in the cooling process must be dissipated. A fixed installation requires a process where the heat is being led out through a pipe to a permanently-mounted outdoor unit. A portable air conditioner has a hose to dissipate the hot air, meaning that no outdoor unit is required. The hose can, for example, be led out through a window in your home.
It is rarely allowed to install a fixed air conditioner in a rental apartment. It may be easier in a condominium, but you should always check with the building association, as the installation can be quite disruptive. The outdoor unit can be fairly noisy, which may be disturbing for the neighbours. You can do as you please with a portable air conditioner, but you should keep in mind that there must be a way to let out the hot air, for example through a window or a balcony.
The air conditioner itself does not make you sick. Bad maintenance of the air conditioner, however, can indeed be harmful to your health. It is very important to change filters every now and then. If you don’t do this, the filters will have the opposite effect; instead of filtering out bacteria, vira, pollen, and dust, a worn-out filter will start to spread the particles in the room.
When choosing air conditioners, it's crucial to ensure they have the right cooling capacity for your space. Cooling capacity is measured in British Thermal Units (BTUs) and determines how effectively the air conditioners can cool a room. As a general rule of thumb, you need about 20 BTUs per square foot of living space. For example, if you have a room that's 300 square feet, you'll need an air conditioner with at least 6,000 BTUs. Make sure to measure your room accurately and consider factors like ceiling height and sun exposure, which might require a higher capacity.
Energy efficiency is key when buying air conditioners, as it impacts both your electricity bill and the environment. Look for air conditioners with a high Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER). The higher these ratings, the more efficient the unit is. An efficient air conditioner can save you money over time by reducing energy consumption. Additionally, consider models with programmable thermostats or smart features that allow you to control them remotely for even greater energy savings.
No one wants an air conditioner that disrupts their peace with excessive noise. Before purchasing, check the noise level rating of air conditioners, usually measured in decibels (dB). For bedrooms or quiet spaces, aim for units that operate below 50 dB. Some modern models are designed with noise-reducing technology to ensure they run quietly without compromising on performance. Reading user reviews can also provide insights into real-world noise levels experienced by other buyers.
