I still don't understand how I am supposed to find out or calcuate int Rc? Is this a number you get from the manufacturer? Which in my case is Panasonic and I doubt I will be able to get a hold them. Any help?!!

Nena,
Can you get the cooling capacity (in tons) and the total pounds of refrigerant in a full charge (lbs of refrigerant) for the equipment from manufacturer cut sheets, technical information documentation, or the company website? Refrigerant charge is calculated by dividing the total pounds of refrigerant in a full charge by the cooling capacity of the equipment. So the resulting value is in units of lbs/ton.

Is the original charge in manufacturer's spec the same as full charge? I can only find the original charge.

The cooling capacity of the split units in our project is calculated according to ISO not ARI standard. Can I use it ?
