Started in the trade working on comfort cooling, high temperature refridgeration. Starteing to make the leap into medium and low temperature refridgeration. Principles are the same, but thats where it stops. Different controls, defrost timers, epr valves, cpr valves, low pressure cut in and out to maintain desired temperatures. New (new to me) refridgerants. Someone help. Any good books or literature?
