Since human beings eat in the world since the day they come to life, the rest needs to be kept. They sought different remedies. It is understood from the storage sections in the caves in the old chests in our country.
 
In the recent past in our country, we know that our farmers have made wells for the soil to store potatoes. By using the technological systems in the best way today, we see that our products today come from harvesting as fresh and intact as our table. Various services have been tried to date.
 
Some of them are like this;
 
1- Vapor compression mechanical cooling
2- Absorption cooling
3- Adsorption cooling
4- Thermoelectric cooling
5- Magnetic cooling
6- Paramagnetic cooling
7- Cooling with a vortex tube
8- Humidifier evaporative evaporative cooling
9- Cooling by means of melt
10- Cooling with expansion of gases
11- Vacuum cooling
12- Cooling with steam pocket injector
13- Sterling cooling
14- Acoustic sound cooling
 
Until today, cooling systems have been in various searches by evolving and trying.
 
Today, the most economical cooling system for us is evaporative evaporation system. This system is the most preferred feature due to its easy and economical. Various companies prefer ammonia cooling in this system. Ammonia system, which is harmful for environmental health, gases that are not harmful to the environment are preferred.
 
Today, A404 gas is used instead of refrigerant R717 ammonia in Cold Storage and Cold Room Systems.
