Dear friend and colleague ,

Here you will find a course and updated book in refrigeration and air conditioning.
Better not found. Is Roy Dossat 100 years ago.

The Indian Institute of Technology has developed this course and you can find it for free on http://nptel.iitm.ac.in/courses/Webc...ew_index1.html

There is no truth in the pocket and those speaking under a black curtain are charlatans
