Re: ac and ref engineer basic knowledge
There are three references you will need to work in AC and refrigeration. One is the ASHRAE handbook -Fundamentals. A new issue is out this year. If you join ASHRAE, which I would recommend, you will receive one handbook per year as part of your memebership fee.
Two other essentials for a practicing ME in any field are Machiniery's Handbook and Mark's Standard Handbook for Mechanical Engineers.
