📘 Principle of Vapour Compression Refrigeration System | RAC

In this video, we explain the principle of the Vapour Compression Refrigeration System (VCRS) in a simple, clear, and exam-oriented manner, specially designed for Diploma and Polytechnic mechanical engineering students.
You will understand how refrigeration is produced using vapour compression, and how heat is absorbed and rejected during the cycle.

This topic is a core concept of Refrigeration & Air Conditioning (RAC) and is frequently asked in polytechnic exams, semester exams, MCQs, short notes, and viva.
