Theoretical and Practical Ammonia Refrigeration: A Work of Reference for Engineers, and Others Employed in the Management of Ice and Refrigeration Machinery (Classic Reprint) Paperback – August 24, 2018

This is a print copy of a scan of a publication from 1895 (not kidding). Apparently it's from some sort of archive from University of California - there are numerous stamps from "Library of the University of California" on the pages. The only reason I give it two stars instead of one is because there is factual information in the book that remains true to this day - things like corrosiveness (of ammonia), explosiveness, specific heat and etc.Other than that this book is a historical curiosity.

It's an awasome book recommended reading for nh3 reefer techs. One of the most informative books on the subjects that is so low cost.
