We could catalog the Evaporative Refrigeration as Natural Refrigeration, simply because it is the one used by Nature. To take a close example, our body, which makes us sweat when the outside temperature is high, by the process of evaporative cooling, evaporate this sweat, and get an immediate refresh.

But in contrast to this Natural Refrigeration, the Evaporative Refrigeration, is what we can call Artificial Refrigeration, or Artificial Cold, the common refrigeration, that of the Air Conditioning, whose problems for the Health of the People are remarkable and that surely we have all perceived in Any occasion.

Control y Ventilación, S.L. is a manufacturer of a line of Natural Refrigeration equipment, Evaporative Refrigeration equipment marketed under the HUMIBAT brand, equipment that uses the evaporation of water to lower the temperature of the air that is introduced into the cabin to be conditioned. Control and Ventilation adds to the goodness of the Evaporative Refrigeration, the ease of maintenance and cleaning and the high and constant performance of its equipment facilitated by its evaporative substrate consisting of a plastic material filling, High Density Polyethylene, marketed in turn as PANAL C&V y SEPARADOR C&V.

Given the importance of the health of the Natural Refrigeration as opposed to the Artificial Cold, we transcribe this article published in El Periódico de Aragón on July 31, 2017.

THE RISKS OF ARTIFICIAL COLD

Dryness of cooling affects the bronchi and causes rhinitis, pharyngitis and asthma

The systems that condition the air to reduce the environmental temperature in summer are complex structures that force the bronchi and larynx to a continuous adaptation so that the flow that reaches the interior of the lungs does not differ in excess of 35 to 37 degrees in that the human body is maintained.

Adaptation to environments that differ in excess of that temperature may not be perfect and cause rhinitis that causes an unstoppable nasal drip, a pharyngitis that lasts all summer, a cervical contracture or a cold induced by any of the respiratory viruses ubiquitous in the air, warns the pulmonologist Xavier Muñoz, attached to the Vall d’Hebron Hospital.
The cooled air is, in addition, too dry, and also demands that the body modulate it. “The oxygen contained in the air conditioning, of extreme dryness, burns the respiratory passages,” says Muñoz. The bronchial cells maintain a constant effort to humidify the air that reaches them, until adapting it to a physiological temperature for the individual ».
It is easy to check the consequences of oxygen in any living element, adds the pulmonologist: it is enough to observe what happens with an orange that is split and left to air. “In a couple of hours, oxygen makes it a wrinkled and aged fruit,” he says. The human organism must ignore all these contrasts: the body is what actually acts as an air conditioner outside, “concludes Muñoz.

The filters of the cooling towers of the large buildings and those of the electric ventilation systems of homes must remain clean, warn the specialists. These filters, and the compressors of domestic appliances that generate heat and condense moisture, favor microorganisms that usually inhabit the environment, such as legionella bacteria or fungi, one of them the aspergillus. These proliferate in environments that the air conditioning maintains at 16 or 18 degrees.
