Hello people a question ... I am repairing a frigobar. The engine is 1/10 hp ... when he charged r134 coolant and brought it to 5 psi for half an hour it doesn't cool anything ... but then I am given a little charge every half hour until it cools but if it the return spout is escrache or anything similar ... until taking it to 2 degrees the only drawback is the psi that shot at 20 psi but the amprerage is below what the label indicates ... you have any idea why Can you raise both psi with only 2 degrees of temperature? How much is the normal temperature inside a frigobar? From already thank you very much! It is an 80 liter scourge with an amprerage of 0.70, r134a refrigerant 26 grams.
