Good afternoon dear experts,
I need to replace R22 on R404A in a refrigerator (0 С … +6 С). I change compressor Embraco NE6181E on NE6181GK, I put the new (clean) evaporator and the condenser.
How to determine the sizes of a capillary tube and amount R404A?
what freon’s values of pressure and temperatures to be guided by?

Thanks for any advice

Let it be!

Go to Embraco website, you will find the amount of refrigerant necessary for each model. R404A is usually for low temp equipments. Since you have capillary for your orifice, you will charge the unit with sub cooling.

Oops! I was surprised no one caught me on this. You should charge by superheat for capillary tube.
