Use of evaporation for refrigeration secret refrigerator works

Public refrigerator is how refrigeration felt is confused, in fact, it's principle is very simple, the liquid into gas to heat absorption.

Conversely, when the gas into liquid to heat. Refrigerator to ingenious arrangements both state changes, in order to achieve the purpose of refrigeration. The refrigerator is the use of evaporative cooling or gasification endothermic effect and achieve refrigeration purposes.

Refrigerator, within the pipes have a commercially known as freon: freon, commonly known as freon refrigerant.

Commonly used a photograph of Dichloromethane (CCL2F2), is a colorless, odorless, non-toxic gases, the boiling point is 29 degrees centigrade.

Freon gas, compressed, compressed, as shown in figure below.

Compression flow by pipe to the condenser, the back of the refrigerator borrow heatsink thermal (material is compressed, the temperature will rise), condensed into a liquid.

Liquid freon enters the evaporator of the valve, due out of compressor pressure immediately into steam, while the air inside the refrigerator and the latent heat of vaporization of food and other lessons (latentheatofvaporization), resulting in the refrigerator to cool.

Vaporization of freon and compressor pressure back to the condenser cooling outside the box, and then into the liquid, so endless, the heat pump in the fridge to the box.

This is the simple process of refrigeration, in fact, the physical above relate to the concept of a class of sublime.
