To all

I am an enginnering teacher at 2nd level in Ireland (ages 13-18)

As part of the leaving certificate(final examination before university) in engineering, students must study a specialised topic and the topic for this year is

"Basic principles and operation of compressors in refrigeration"

I would be grateful if anyone has any notes or can lead me to a website that would be useful

my email is alan.mongey@ul.ie

thanking you in advance

I would seem any study of compressor operation would necessarily with some thermodynamics and the ideal refrigeration cycle. Chapter 1 of the ASHRAE Fundamentals Handbook provides a nice overview of this subject. Some areas that can be considered for study


Carnot cycle and the second law of thermodynamics
The ideal refrigeration cycle
The ideal compressor
Ideal gas law; Boyle's Law; Charles' Law

These subjects can get a bit technical. Your average 16 year old may blanch at the idea of explaining compressor operation in terms of the second law. :confused:
