Heat of condensation
The energy transferred from the
condenser to the air is composed
of:
1. Heat energy previously removed
in the evaporator.
2. �lectrical motive energy.
3.
Heat of condensation released
during condensation of the wa-
ter vapour.
For the change from a liquid to a
gaseous state, energy is necessary.
This energy is called heat of eva-
poration. 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 con-
densation.
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 lar-
ge amount of energy is released
through the condensation of water
vapour.
If the moisture to be condensed is
not introduced through evaporati-
on in the room itself, but from out-
side, 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 dehumidi-
fication 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 de-
termined by the rate at which the
material or parts of the building
release their moisture.
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 persons who
have not been instructed in their
use, improperly or not for the in-
tended purpose.
The following information must
be observed:
■ The units must not be installed
and operated in hazardous are-
as.
■ The units must not be installed
and operated in oil, sulphur,
chlorine or salt containing at-
mospheres.
■ The units must be installed up-
right and stable.
■ The units must not be exposed
to direct water jets.
■ The air inlet and outlet must al-
ways be kept free.
■ The air inlet grilles must always
be kept free of dirt and loose
objects.
■ The units must not be covered
during operation.
■ Never insert foreign objects into
the units.
■ The units must not be transpor-
ted during operation.
■ The units must only be transpor-
ted upright.
■ All electrical 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 equip-
ment must be referred to an
authorised specialist!!
