Key Features of the Book

The book is widely regarded not just as a textbook, but as a complete learning system. Here is why it stands out:

A. Dated Industry Standards

The core laws of thermodynamics do not change, but the industry does. The book uses older examples regarding refrigerants (like R-12 or R-22), which are now largely phased out due to environmental regulations (Montreal and Kigali Protocols). While the physics remains the same, students must be aware that the specific refrigerants highlighted may not reflect modern industry standards.

A Comprehensive Review: Refrigeration and Air Conditioning by R.S. Khurmi
