Safety notes
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.
The units have been subjected to
extensive material, functional and
quality inspections prior to delivery.
However, dangers can result
from the units if they are used
improperly or not as intended by
untrained personnel.
The following notes
must be observed in full:
■
The units may not be installed
or operated in explosive
environments
■
The units must not be installed
or operated in atmospheres
containing oil, sulphur, chlorine
or salt
■
The units must be installed
upright and in a stable position
■
The units must not be exposed
to direct jets of water
■
An unobstructed air inlet and
air outlet must be guaranteed
at all times
■
The air-inlet grille must always
be kept free of dirt and loose
objects
■
The units must not be covered
during operation
■
Never stick foreign objects into
the units
■
The units must not be
transported while they are
running
■
The units may only be
transported upright
■
All electrical cables on the
outside of the units must be
protected against damage
(e.g. by animals etc.)
■
Before each change of location,
the condensate container must
be emptied
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit power
consumption, cable length and
local use.
Work on the refrigerant
system and on the electrical
equipment must only be
conducted by a specially-
authorised specialist!
