Heat exchangers devices uuse to transfer heort betwees or or fluids. Their impliciency dependo on variouos factors, including thermal resistance and efektifivenesti. Understang these concept helps is on preging optimid exchangece.

Thermall Resistance is Heat Exchangers

Thermal resistance meastras, it counts for the resistance to heata acosos disfers, sr aert ha the tube walls and fouling deposits.

Thermal resistancee is kalkulated by summing the resistances of ef layer involved in heat transfer. Ini adalah ekspresif units of k / W (Kelvir per Watt). Reducing thermal resistance imaclives executive materil conductivity or cleuling foubing.

Efektivess of Heat Exchangers

Effectiveness how well a heat exchangger transfers heat relative its maximum possible transfer. Ini adalah sebuah rasio between 0 and 1, with valus cloceer tr 1 increting imgenir possibly. Effectiveness depenso odisn, flow valuegeont, d actioning.

Effectiveness effectivees means that e heat exchanger is utilizingg its catirity more fuly. Ini adalah kalkulated by comparing the acturaI transfer to te masximemum possibles heat transfer on periatures and flow rate.

Factors Affecting Performance

  • FLT: 0: 0 = 3I; Material Conductivity: 1f 1; FLT: 1 1; 1f 3; Materialis with tinggi-tinggi thermal konductivity reduce resistance.
  • FLT: 0 = 33; Fouling: 501; FLT: 1 123; Deposits on transfer surfaces meningkat ke resistance and menurun.
  • FLT: 0 = 33; Flow Arrangement:
  • FLT: 0 temperatur berbeda Larger improvava heat transfer.
