6 Myths about Air Conditioning


Summer is not yet over. There is still heat in some cities, which will not even recede by September. But right now, many people have started thinking about how to install air conditioners. There are many misconceptions about the work of an air conditioner. Let’s unmask the most common of them.

6 Myths about Air Conditioning

Air conditioner causes cold

Of course, you can catch a cold if you stay for a long period near the device in such a way that it blows straight at you. Nevertheless, an air conditioner is equipped with special dampers that change the direction of airflow. If properly placed, it cannot inflict harm.

Besides, it is necessary that an air conditioner is correctly installed. It is better to place it in such a way that it does not blow at anyone at the back. Therefore, when ordering for a conditioner, tell how the sofa and bed in your apartment are located.

Air conditioner ventilates a room

Air conditioners do not ventilate a room. Many people confuse ventilation with air conditioning and believe that the external power unit pumps fresh air from outside. In fact, it cools the refrigerant circulating inside it. Therefore, it is necessary to ventilate the house. It is better to organize a draft for at least thirty minutes before going to bed.

Inflow of air from outside can be actualized only by duct air conditioners mounted in the ceiling and walls of a building.

Air conditioners spread bacteria

There is a myth that legionellae multiply rapidly in the humid surroundings of an air conditioner. These bacteria breed exclusively in central air conditioning systems operating on the principle of recycling water supply. Such conditioners are however rarely used.

In household air-conditioners, a dirty filter in the bathtub drain may lead to the emergence of unpleasant odor and harmful bacteria. Consequently, most air conditioners should be cleaned at least once a month and filters should be changed in time. In some newer models of air conditioners, self-cleaning filters that require cleaning and replacing filters rarer are used.

The more powerful, the better

It makes no sense to put a very powerful unit in a small room. Such air conditioners can create strong air currents that can make you catch cold and cause papers on your desk fly about like butterflies. The opposite situation is no better: a low-capacity compressor in a large hall will burn down after a month due to excessive load. Determine the required power in advance.

Air-conditioners consume much electricity

Air-conditioners consume less energy than an electric kettle or a smoothing iron.

Air conditioners can replace central heaters

Many air conditioners can indeed work not only in a cooling mode but also as a heater. However, an air conditioner can maintain a comfortable temperature in the room only if the temperature outside is not below -7°C. This figure does not depend on the brand or capacity of the conditioner: such are the physical properties of the coolant.

Outdoor units of most air conditioners are covered with ice during winter thereby causing a breakdown. For that reason, it is far more rational to use an air conditioner during off-season: it is cost-effective and safer.
