Heat of condensation
The energy transferred from the
condenser to the air is composed
of:
1. Heat energy previously removed
in the evaporator.
2. Electrical motive energy.
3. Heat of condensation released
during liquefaction of the water
vapour.
For the change from a liquid to a
gaseous state, energy is necessary.
This energy is called 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, energy is released
during the liquefaction of
gas, which is called heat of
condensation.
The amount of heat of evaporation
and condensation is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
This shows that a relatively large
amount of energy is released
through the condensation of water
vapour.
If the moisture to be condensed
is not introduced through
evaporation in the room itself, but
from outside, e.g. via ventilation,
the heat of condensation released
in the process contributes towards
room heating. In drying processes,
the heat energy is recirculated,
which is consumed during
evaporation and released during
condensation.
The supplied air
during dehumidification creates
a large amount of heat energy,
which is expressed as a rise of
temperature.
The time necessary for drying
normally does not depend only
on the unit capacity, but is rather
determined by the rate at which
the material or parts of the
building release their moisture.
The units were subjected to
extensive material, function and
quality inspections and tests prior
to delivery.
However, the units may constitute
a hazard if used by persons who
have not been instructed in their
use, improperly or not for the
intended purpose.
The following information must
be observed:
■ The units must not be installed
or operated in locations subject
to explosion hazards
■ The units must not be installed
and operated in oil, sulphur,
chlorine or salt containing
atmospheres.
■ The units must be installed
upright and stable.
■ The units must not be exposed
to a direct jet of water.
■ The air inlet and outlet must
always be kept free.
■ The air intake grilles must
always be kept free from dirt
and loose objects
■ The units must not be covered
whilst in operation.
■ Never insert foreign objects into
the units
■ The units must not be
transported during operation.
■ The units must only be
transported upright (water
spillage).
■ All electric cables outside the
units must be protected against
damage, e.g. by animals, etc.
■ The condensation collectors
must be emptied prior to each
change of location.
aTTEnTiOn
Only qualified electricians may
extend the connecting cable
taking into account the rating
of the unit, cable length and
use locally.
aTTEnTiOn
All work on the refrigeration
system and electrical
equipment must be referred
to an authorised specialist
company!
