Heat of condensation
The energy transferred from the condenser to the air consists of: The heat earlier transferred
from the evaporator. Real electrical power. The heat of condensation released through the
condensation of water vapor. When liquid turns into a gaseous state, the energy should flow
in reverse. This energy is called the heat of evaporation. It does not cause any rise of
temperature, it is only necessary for the change from a liquid to a gaseous state. Vice versa,
the energy is released when gas turns into liquid, such energy is called heat of condensation.
The heat generated at condensation and evaporation and is identical. For water this is
2250kJ/kg (4.18kJ = 1kcal). This shows that a relatively large amount of energy is released in
the process of water vapor condensation. If the moisture to be condensed is not generated at
evaporation in the room but is introduced from outside, e.g. via ventilation, the heat of
condensation released in the process will be used for the room heating. If it is required to dry
materials or rooms the heat energy recirculates, i.e. it is consumed during evaporation and is
released during condensation. A large amount of heat energy is generated at the supplied air
dehumidification process, which is expressed as a rise of temperature. Normally the time
necessary for drying does not depend only on the unit capacity, but is determined by the rate
at which the material or the building elements release the moisture they contain.
