Component Specifications

Definition
Tubing in evaporator coils is a critical component in refrigeration and air conditioning systems, designed to facilitate efficient heat transfer by circulating refrigerant. It typically consists of serpentine or coiled configurations that maximize surface area for heat absorption from the surrounding air or medium. The tubing must maintain structural integrity under varying pressures and temperatures while ensuring minimal thermal resistance and leakage.
Working Principle
Operates on the principle of phase-change heat transfer, where refrigerant inside the tubing evaporates from liquid to vapor, absorbing latent heat from the external environment. This process cools the surrounding air or fluid, with the tubing's design optimizing thermal conductivity and flow dynamics.
Materials
Commonly made from copper (C12200 or C11000) for high thermal conductivity and corrosion resistance, or aluminum alloys (e.g., 3003 or 6061) for lightweight applications. May include coatings or alloys for enhanced durability in specific environments.
Technical Parameters
  • Diameter 3/8" to 5/8" (9.5 mm to 15.9 mm)
  • Surface Finish Smooth or enhanced (e.g., micro-grooved) for improved heat transfer
  • Wall Thickness 0.032" to 0.049" (0.81 mm to 1.24 mm)
  • Pressure Rating 300 to 600 psi (2.07 to 4.14 MPa)
  • Temperature Range -40°F to 250°F (-40°C to 121°C)
Standards
ISO 9303, DIN 2391
