Heat of condensation (definition)

Condensation heat — is the amount of heat released when steam condenses into liquid. This process occurs when steam, which is in a gaseous state, is cooled to a temperature at which it changes into a liquid phase, forming condensate.

Condensation heat: basic aspects

• Condensation process:
  • Description: Condensation occurs when steam cools to a temperature below the dew point. In this process, the steam loses its internal energy and turns into a liquid, releasing heat.
  • Application: In heating and air conditioning systems, condensing heat is used to increase the efficiency of heat exchangers and boilers.
• Condensation heat and energy:
  • Energy efficiency: In condensation boilers, for example, additional heat is used to increase the efficiency of operation. The heat exchanger in such boilers allows for the extraction of additional heat from the condensate, which increases the overall efficiency of the heating system.
  • Examples: In condensing boilers and some heating and cooling systems, this heat is converted into additional useful heat, reducing fuel consumption and increasing overall system efficiency.
• Formula and units of measurement:
  • Formula: The parameter can be calculated using the formula $Q=m\cdot L$, Where $Q$ — the amount of heat, $m$ — the mass of condensate, and $L$ — specific heat of condensation.
  • Units of measurement: Usually measured in joules (J) or kilocalories (kcal).
• Application in practice:
  • Boilers: Condensing boilers use the heat of condensate to extract heat from the water that is formed during combustion of fuel, increasing the overall efficiency of the boiler.
  • Climate systems: Condensate heat is also used in systems where heat exchange and maintaining a set temperature are required.

Condensation heat is an important aspect in systems designed to maximise energy efficiency and reduce resource consumption, ensuring more efficient use of energy.
