How to avoid colds from air conditioning in summer?

The hottest season of the year is here and with it the problems associated with air conditioning, which 'make' our hot working days more enjoyable. Have you ever encountered coming home from work after a busy day and having a cold the next day? In a summer where everyone would think it's almost impossible to get a cold? This summer cold usually comes from the sharply cooled office space in which we move. We have given you some explanations as to why this is the case and how to avoid it.

What does heat and cold do to the air?

You probably always thought that the heat was rising and the cold was falling down. But the claim is not entirely correct. It is more correct to say that warm air rises upwards and cool air falls down. We'll explain it in a simple example. If we imagine a hot air balloon, we realize very quickly how the mechanism works. Warm air is steered into the sail, which immediately begins to lift the shell and float it. If we stop heating the air, the shell will begin to sink to the ground. This is a natural and immutable mechanism that works and is verified.

Classic air conditioning works the other way around than it should.

Let us now translate the like-up we used in our example to something we all know well. We spend our working day in a classic openpac, and from above the air conditioning blows on us, when the sharply cooled air falls directly to the ground (from there we know such an unpleasant phenomenon for ladies, cold from the feet). Now imagine that you are in a wine cellar, where you are pleasantly cooled by the cooled walls in the space. What's more pleasant? Air conditioning blowing or cooler radiation in the cellar? I'm sure we can all agree that B). On this principle, radiant cooling systems work, the bodies of which cool down and then radiate the cold evenly into the space and without temperature shocks.

Solution? Natural airflow.

Do you think if you turn on the air conditioning in the summer, in a room where it's hot, you'll feel better? Yes, if you let the classic air conditioning blow on you all day, you will feel colder, but it is very likely that after such a day at work, you can just lie down in bed with tea for a week. The healthiest and most natural way of cooling in this case is natural flow, which can be achieved with radiant technology that works with smaller temperature differences than conventional air conditioning.

Air conditioning cools the air with water, which has a very low temperature (6°C) compared to outdoor air, causing us to feel unassuged in air-conditioned areas, we have a cold and such sharply cooled dry air does not allow us to breathe comfortably. Radiant technology works with water at a significantly higher temperature (18°C) and is thus closer to summer temperatures. Thanks to the fact that the temperature shocks for the body are not so great, then we can then function all day without having a cold and breathing dry air all day.
