Refrigerant Line Charge Calculator
Calculate the proper refrigerant line charge for HVAC and refrigeration systems. Determine the correct refrigerant amount based on line length, diameter, refrigerant type, and system specifications.
Step 1: Line Specifications
Understanding Line Charge
Proper refrigerant line charge calculation is essential for HVAC system efficiency. Too little refrigerant reduces cooling capacity, while too much can damage the compressor and reduce efficiency.
Step 2: Refrigerant Parameters
About Refrigerant Density
Refrigerant density varies by type and temperature. Higher temperatures typically decrease density, requiring more refrigerant to fill the same volume. Always refer to manufacturer specifications for precise calculations.

Refrigerant Charge Formula
Refrigerant Charge = π × (Diameter/2)² × Length × Density × Safety Factor
To calculate refrigerant charge: Calculate line volume using cylinder volume formula, multiply by refrigerant density at ambient temperature, then apply safety factor for optimal system performance.
