Home Blogs Refrigerant Line Sizing – Formulas and Calculations Calculator July 12, 2024 Introduction to Refrigerant Line Sizing Proper sizing of refrigerant lines is crucial for efficient operation of HVAC systems. It involves considerations such as refrigerant type, load calculations, and line diameter. Key Considerations Refrigerant Type and Pressure Drop Load Calculations (Cooling or Heating) Velocity and Flow Rate Requirements Pipe Material and Insulation Formulas and Calculations Pressure Drop Calculation: ΔP = f * (L / D) * (ρ * V^2 / 2) Where: ΔP: Pressure drop f: Friction factor L: Length of the pipe D: Diameter of the pipe ρ: Density of the refrigerant V: Velocity of the refrigerant Refrigerant Line Sizing: D = √( (4 * Q * ρ * V) / (π * ΔP) ) Where: D: Diameter of the refrigerant line Q: Flow rate of refrigerant ρ: Density of the refrigerant V: Desired velocity of the refrigerant ΔP: Maximum allowable pressure drop Example Calculations Example 1: Refrigerant Line Sizing Given: Refrigerant: R-410A Flow Rate: Q = 0.5 kg/s Density: ρ = 5 kg/m3 Desired Velocity: V = 5 m/s Maximum Pressure Drop: ΔP = 100 kPa D = √( (4 * Q * ρ * V) / (π * ΔP) ) D = √( (4 * 0.5 * 5 * 5) / (π * 100) ) D ≈ 0.399 m Therefore, the recommended diameter of the refrigerant line is approximately 0.399 meters.
