WHAT IS COOLING AND WHAT IS THE OLDEST FORM OF COOLING?

Keeping an environment constant at the desired temperature and ensuring its continuity can be called “Cooling”. In short, the degree obtained by transferring the heat in an environment to the outside is called “Cooling”. In the field of application, for the first time in 1860, Dr. James Harrison (Australia) successfully used mechanical cooling during the production process.

The simplest and oldest form of cooling is to keep the ice formed by nature in cold regions and to provide cooling by placing them in hot or heat-required places. It is known that the method of preserving the Snow and Ice that occurs in winter and using it for cooling purposes in the hot seasons has been applied since 1000 BC. It is seen that this practice is a valid form of cooling in some parts of our country even today. Another method, since the ancient Egyptians, is known to cool the water in ceramic jugs, which are placed in such a way that they can see the sky with their mouths open at night. This cooling method is provided by making use of the fact that the temperature of the sky in the dark at night is at absolute zero (-273 C) and the heat is transmitted to the sky by radiation.
