How Refrigeration Equipment Works?

Views: 56401/08/2020  

First of all, what is refrigeration? Refrigeration can only be said to be a technical term. Strictly speaking, there is no country in the world where scientists can make "cold". We use mechanical equipment to reduce the temperature of the cooling object to the required temperature. This is the term refrigeration.

How cold room refrigeration equipment works? For example, we put a kettle with a kilogram of 20 ℃ cold water on an iron plate that is heated to 500 ℃. The water will boil soon. If we don't take the kettle apart, the water will dry soon. It is said that the steel plate is heating the water, which in turn can also be said that the water is cooling the steel plate. Moreover, how many degrees have been reduced can be calculated. Because a kilogram of water rises from 20 ℃ to 100 ℃, it needs 80 calories from the outside world. From 100 ℃ to dry, it needs 539 calories from the outside world. That is to say, a kilogram of cold water burns to dry, and 619 calories from the outside world. If it extracts 619 calories of heat from the outside of the steel plate and turns into water vapor to cool the steel plate, this is refrigeration, which uses water to cool the steel plate. Heat is always transferred from the object with high temperature to the object with low temperature through conduction, convection, and radiation, which can never be reversed. When an object loses some heat, its temperature will decrease a little. Our purpose is to transfer the heat in the medium to the specific refrigerant through the refrigeration system, to reduce the medium temperature.
