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 evapo-
ration 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 ener-
gy is recirculated, which is consu-
med during evaporation and relea-
sed during condensation.
During dehumidification of
the supplied air, the amount of
heat energy produced is greater
than that expressed in 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 build-
ing release their moisture.
Safety notices
The units were subjected to ex-
tensive material, functional and
quality inspections and tests prior
to delivery.
However, the units may constitute
a hazard if used by untrained per-
sonnel, 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 atmospheres
containing oil, sulphur or salt
■
The units must not be exposed
to direct water jets
■
The air inlet and outlet must al-
ways be kept free
■
The air intake grilles must al-
ways be kept free of dirt and
loose objects
■
The units must not be covered
during operation
■
Never insert foreign objects into
the units
■
All electrical cables outside the
units must be protected against
damage (e.g. by animals, etc.)
ATTENTION
All work on the refrigeration
system and electrical
equipment must be referred to
an authorised specialist!
■
The units must only be installed
or mounted in the intended po-
sition (horizontal)
■
Free and frost protected
condensate drain must always
be ensured
■
The unit connections must al-
ways be established in compli-
ance with the applicable instal-
lation regulations
