Table 56: Single Zone Mega, Standard Efciency, and Mega 115V Piping System Additional Refrigerant Charge.
• Capacity is based on standard length.
• Equivalent Pipe Length = Actual Pipe Length + Number of Bends x 0.3.
• Additional Refrigerant Charge Calculation : X (g) = [ (Refrigerant Pipe Length) - (No Charge Pipe Length) ] × (Additional Refrigerant).
• There is no need to add refrigerant if equivalent pipe is less than the “piping length with no additional refrigerant” in the table above.
