Capacity of Heat Exchanger

The heat exchange amount of the heat exchanger is determined by the circulating amount of the heat medium circulating, the circulating amount of the exchange fluid, the heat transfer area and the heat transfer speed of the heat exchanger, and the average water temperature difference between the two exchange fluids.

Q = U × A × ΔT

  • Q Heat exchanged = kcal/hr
  • A (Heat transfer area) = the indirect contact area of the two fluids being heat exchanged m2
  •  U Overall heat transfer coefficient: kcal/㎡-hr-℃
  • The amount of heat exchanged for 1 hr at the indirect contact surface per 1 ℃ of temperature deviation (ΔT) per 1 m2 of the heat transfer area of the heat exchanger
  • It depends on the heat conduction of the metal material constituting the heat exchanger and depends on the characteristics of the exchanged fluid.
  • ΔT = average temperature difference (Δ℃)
  • Units used in heat exchanger design
    – Calorie 1kcal/h = 1.163W
       1 W = 0.86 kcal/h
       1kW = 860 kcal/h
       1usRT = 3,024 kcal/h
    – Heat flux
       1kcal/m2/h = 1.163 W/m2
       1W/m2 = 0.86 kcal/m2-h
