SCImago Journal Rank (SJR indicator) is a measure of scientific influence of scholarly journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from.
Refrigeration is a vital technology that has revolutionized various industries, including food processing, preservation, and transportation. The principles of refrigeration are essential to understanding how refrigeration systems work and how they can be applied to different fields. In this essay, we will cover the fundamental principles of refrigeration, as outlined in the book "Principles of Refrigeration" by Roy Dossat.
You can find more details in "Principles of Refrigeration" by Roy Dossat.
Refrigeration is the process of removing heat from a substance or a system, resulting in a decrease in its temperature. This process involves the transfer of heat from a colder body to a hotter body, which is opposite to the natural flow of heat. Refrigeration is used to preserve food, cool buildings, and even preserve biological samples.
In conclusion, the principles of refrigeration are essential to understanding how refrigeration systems work and how they can be applied to various fields. The refrigeration cycle, types of refrigeration systems, key components, and applications of refrigeration are all critical aspects of this technology. As outlined in the book "Principles of Refrigeration" by Roy Dossat, these principles provide a foundation for designing, operating, and maintaining refrigeration systems. By understanding these principles, engineers, technicians, and researchers can develop more efficient and effective refrigeration systems that meet the demands of various industries.

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?
Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
