Bar fridge refrigerant pressure

Bar fridge refrigerant pressure

Bar fridge refrigerant pressure

(OP)
I have a question about stats for a typical small fridge.
like this one for example;
http://www.backwoodssolar.com/Catalogpages2/refriger2.htm
NOVAKOOL R-4500 PLUS 25

I am wondering how much work the compressor has to do on the refrigerant and what pressures are involved.
eg. What is the pressure difference, and therefore temperature difference created by the compressor both on the high pressure side and low pressure side on the cycle.
Also the flow rate would be useful.
ie, what volume of refrigerant is pumped through the pipes on a typical day/hour in a small bar fridge, and what would the total volume of refrigerant be?
I guess this question could be reframed as "what are the likely approximate pumping stats of the compressor".

I hope this is not a stupid question.
I am only need approximate answers.
Thanks for the great forum.
