Cooling in the caves

The first men who inhabited the Earth took refuge in caves, but is this a coincidence? The reality is, no.

The caves were not only a refuge to avoid predators at night but also a refuge to combat bad weather . When we talk about bad weather it is not only when it snows excessively or when the rains are torrential, it is also considered bad weather when the heat reaches a point that is unbearable.

That is why the caves were essential. The caves managed to maintain an average temperature in relation to the outside temperature. They talked about an inner heat in winter and a bearable cold in summer.

Civilizations: another form of cooling.

The first refrigeration techniques

The first refrigeration techniques were based on building using materials that insulated from temperatures. These constructions were the well-known huts of the first nomads. In this way, they also looked for the ideal place to stay safe from climatic changes.

Egyptian refrigeration techniques

In Egyptian times they had a clear solution to meteorological problems: air currents . Both the buildings and the techniques were focused on creating these air currents.

Even the orientation of the streets, the use of windows, doors and corridors were also intended to benefit these air flows.

Vertical tunnels were also built in the houses to improve the air outlet.

Refrigeration according to the pharaohs

Legend has it that the pharaohs had their own cooling techniques and they were also quite extreme.

At night they were dedicated to dismantling the stones that closed the interior of the royal palace and left them out in the open all night in the middle of the desert. In this way, full cooling was achieved when those same stones were put back into position in the morning. best refrigerator in bangladesh

Although it was a rather laborious method, it was the best way to keep the entire palace refrigerated throughout the day.

Another cooling technique: snow pits

From Mesopotamia to the Romans there was a common obsession to combat the days of harsh heat: ice and snow. For this reason, the wells or houses that were made were made of snow.

Considering that the most important business of the time was the snow trade, and that wealthy families of the time wanted to stay sheltered from the heat, snow pits were essential. Hence, every wealthy family had one in their inner courtyard.

However, those who did not have so much money to install a well in their house, settled for cooling their houses by putting snow or ice on the structure. In addition, they also put sawdust as insulation and even added drains to take advantage of the cold water.

Arrival of air conditioning: latest refrigeration technique

And finally the air conditioning arrived . Our great salvation from the climate change that we are currently suffering and, although some are fan lovers, more and more of us are within this community. The high temperatures do not let us rest and not only in the summer months.

Due to this, during this particular summer, we have seen how companies that sell both air conditioners and fans have had a large stock break.

Shop windows without products and houses like freezers. That is the phrase that sums up the refrigeration technique used by today's civilization.
