Types Of Refrigerants And Uses Pdf
File Name: types of refrigerants and uses .zip
Refrigerant is a compound typically found in either a fluid or gaseous state. It readily absorbs heat from the environment and can provide refrigeration or air conditioning when combined with other components such as compressors and evaporators. Air conditioners contain refrigerant inside copper coils.

Classification of Refrigerants: Primary Refrigerants: can be directly used for the purpose of refrigeration. Classification of Refrigerants: Secondary Refrigerant: there may be certain situations in which we cannot allow the refrigerant to come in direct contact with the items being refrigerated, and then the refrigerant used is termed as a secondary refrigerant.
Here, the first digit represents the number of carbon atoms in the compound minus one, the second digit stands for the number of hydrogen atoms plus one while the third digit stands for the number of fluorine atoms. The remaining atoms are chlorine. Designation of Refrigerants: 7 8.
Designation of Refrigerants: 8 9. Thomas Migely in Types of Refrigerant: 10 Types of Refrigerant: Hydro-carbons. Desirable Properties of an Ideal Refrigerant: 17 Water: When the required temperature to be maintained is above the freezing point of water, then water is universally used as secondary refrigerant mostly in air-conditioning plants and industrial cooling installations.
Brines: When the temperatures required to be maintained are below the freezing point of water then the water cannot be used, in such case brine solutions are used.

Clicking on the donut icon will load a page at altmetric. Find more information on the Altmetric Attention Score and how the score is calculated. These separate aspects are intimately intertwined and have been in more-or-less continuous development since the earliest days of mechanical refrigeration, even if sometimes out-of-sight of the mainstream refrigeration industry.
5.4 Refrigerant types
The equipment used for removing the heat continuously for maintaining a low temperature in a space is called 'refrigerator'. In the last session, we had discussed Vapor Compression Refrigeration Cycle and in today's session, we can discuss in detail the concept of Refrigeration along with its Definition, Unit, Classification of Refrigerants and Applications. Refrigeration may be defined as a process of removing heat from a substance and pumping it to the surroundings.
