Condensation heat
The energy transferred to the air
from the condenser consists of:
1. The amount of heat derived
beforehand in the evaporator.
2. The electrical drive energy.
3. The condensation heat released
by liquefying the water vapour.
Energy must be supplied when
liquid is converted into a gas.
This energy is designated as
evaporation heat. It does not cause
any increase in temperature, but is
required to convert a liquid into a
gas. Conversely, energy is released
when gas is liquefied, this is
designated as condensation heat.
The amount of energy from
evaporation heat and condensation
heat is the same.
For water, this is:
2250 kJ/kg (4.18 kJ = 1kcal)
From this it is evident that the
condensation of water vapour
causes a large quantity of energy
to be released.
If the moisture that it is to be
condensed is not introduced by
evaporation in the room itself,
but from outside, e.g. through
ventilation, the condensation
heat released contributes to
the heating of the room. With
drying operations, a heat cycle
is created, whereby heat is
consumed for evaporation and
released for condensation. When
dehumidifying fed air, a larger
contribution of heat is created,
which manifests itself as a
temperature increase.
Generally speaking, the time
required for the drying process is
not only dependent on the output
of the unit, but is determined to
a greater extent by the speed at
which the material or building
section loses its moisture.
Safety notes
General safety notes
■
Carefully read the manual before
commissioning the units or their
components for the first time. It
provides useful tips and notes
such as hazard warnings to pre-
vent injury and material damage.
Failure to follow the directions in
this manual can endanger per-
sons, the environment and the
equipment itself or its compo-
nents and will void any claims for
liability.
■
Store this manual and the infor-
mation required for the operation
of this system (e.g. refrigerant
datasheet) in the vicinity of the
units.
■
This unit may only be installed
and operated as described in this
manual.
■
Independent conversion and/or
modification of any kind is strictly
prohibited.
■
National regulations in connec-
tion with installation must be
observed.
■
Children must not be left unsu-
pervised when close to the unit.

via a power supply with ground-
ing.
■
The use of extension cables is not
recommended.
■
The air filter must be cleaned
at intervals of no more than 2
weeks.
■
The unit is not permitted to be
operated in the vicinity of heat
sources.
■
The unit must be transported up-
right. Residue from the conden-
sate must be drained off before
transport.
