Hi, Is there any method to know the thermal output of a compressor if I know the type of refrigerant and amount that is used? I only know the voltage and running current and amount and type of refrigerant.

Thank you all.

? Of the compressor or the whole system? What exactly do you want to know? It can get very complicated, that's why design engineers have engineering degrees. Coils, surface areas, airflow over coils, temperatures, dry and wet bulb, all factor in.

Well, first I appreciate your help so much. Here is the situation and the information in hand.
There is a robotic welding machine which is controlled by an electrical control panel. This panel consumes too much power and the heat dissipated from it is huge amount. The electrical panel manufacturer added a built-in air conditioning to it to cool it down because when it reaches high temperature it disconnects because the thermal overload. This built-in air condition is out of order (the compressor) and the manufacturing company is closed and the model is obsolete. I want to to replace this compressor with new one, but all what I know about the old compressor is the voltage, ampere, type of refrigerant and the amount it takes of it. No more data is available. Is there any way to know how much cooling capacity this old system was providing to be able to supply new spot cooling mechanism to the electrical panel? Note that no manuals are available on hand or over the internet.

Thank you very much,

Gasser

There should be a plate welded to the top of the compressor, it will have the manufacturer and model, you can cross reference that to, lets say, a Bristol or Copland compressor.
