Condensate Cooling Duty Calculator — Sensible Heat, kW & Annual Energy

Calculate sensible cooling duty when hot condensate is cooled to a target temperature, plus annual recoverable or rejected thermal energy.

Inputs

Results

Cooling duty 93.02 kW
Heat rate 317405 BTU/h
Annual thermal energy 558133 kWh
Temperature drop 40.0 °C

Formula

Q=ṁCp(Tin−Tout)/3600.

Worked example

Cooling 2,000 kg/h condensate from 90°C to 50°C releases about 93 kW of sensible heat using Cp=4.186 kJ/kg-K.

Assumptions & limits

  • Sensible liquid cooling only; flash steam and phase change require a steam-property calculation.
  • Use an appropriate liquid heat capacity when chemistry or temperature makes the water approximation unsuitable.

FAQs

What does this Condensate Cooling Duty Calculator calculate?

Calculate sensible cooling duty when hot condensate is cooled to a target temperature, plus annual recoverable or rejected thermal energy.

What should I verify before using the result?

Check units, operating point, measured site data and OEM limits. This calculator is a transparent screening tool, not a substitute for equipment selection or code-required design.

Why are intermediate results included?

Intermediate values expose the engineering chain so you can audit assumptions, compare scenarios and catch unrealistic inputs.
