REFRIGERATION TUTOR |
|
INTRODUCTION :-
Vapour Compression Refrigeration Cycle is a very widely used
cycle. The main object is to demonstrate Refrigeration system
with basic components and necessary controls. The practical
working is demonstrated here and also a considerable amount of
theoretical analysis and performance can be studied. |
