The number one cause for
costly production downtime
is an excessive component
temperature. The priority,
therefore, is to discover and
eliminate the hot spots.
Rittal value-added service:
Thermal analysis of
enclosures and electronic
housings using CFD simulation
and infrared thermography.
Your reliability is our concern!
TO P PE R F O R M A N C E
Cooling output – efficient generation, focused air
circulation.

Wallmount designs provide
even cooling throughout!
A “short-circuit” in the internal
air circulation is avoided – even
without baffles – due to the
distance between air inlet and
outlet.
6
Roofmount versions are
perfect for every situation.
The air intake for the external
circuit is always from the front,
with the outlets to the sides and
rear. An outlet to the top is also
possible as a special configuration. The internal air circulation is targeted and efficient:
the warm air is removed centrally and the cooled air is supplied as necessary at the four
corners. An air-ducting system
permits targeted distribution
of this cooling stream.

ROOFMOUNT AIR CONDITIONERS
Overview
Roofmount
air conditioners
5200 BTU/1520 Watt
Maximum flexibility
Completely redesigned interior air circuit. The warm air in the
enclosure is removed centrally by the air conditioner. The cold air
is then introduced at up to four outlets arranged at the side
corners. This optimizes cold air circulation within the enclosure.
Many possibilities for air routing
Variable external air circuit. The air intake is at the front of the
air conditioners, while the warm air exhausts for the external circuit
are to the sides (right and left) and to the rear of the unit. The
customer is therefore totally unrestricted in a choice of site or in the
decision to mount a series of air conditioners on a bayed enclosure
system against the wall.
For bayed enclosure suites located against a wall, roofmount air
conditioners with warm air exhaust through the top surface are
available as a special order.

Metal filter for Rittal
TopTherm air conditioners
Rittal air conditioners are low-maintenance
and are supplied without filter mats. Filter
mats may be used for extreme conditions.
Particularly when air conditioners are used
in dusty and damp environments, it is
advisable to use washable metal filters.
If air or steam condenses on the metal
surfaces, any particles that may be present
will adhere to the metal and are easily
washed out with water or grease-dissolving detergents.
Material:
Open-celled polyurethane foamed plastic
with excellent physical and mechanical
properties. Temperature-resistant from
– 40 °F to 176 °F/ – 40 °C to + 80 °C.

Quick-change frame for
roofmount air conditioners
The quick-change frame is more than just
an alternate frame. The sealing gasket is
used to screw the quick-change frame to
the enclosure, allowing the ready-wired air
conditioner to be installed or removed from
the quick-change frame from the outside,
using quick-release fasteners. This means
shorter assembly times and minimum
downtime during servicing. In addition,
quick-change frames offer effective protection against the ingress of oil in oily atmospheres, due to their integrated drainage
trough.

Air duct system for
Rittal TopTherm
roofmount air conditioners
With the air duct system for Rittal TopTherm
roofmount air conditioners, it is possible to
route the cold air directly to specific areas
of the enclosure. The risk of “short circuits”
in the air circulation due to installed
devices with their own ventilation is thus
capably eliminated. Covers can be used to
cover unused cold air outlets.

SK BUS system for
Comfort Controllers
The SK BUS system creates communication facilities between several TopTherm air
conditioners. The BUS uses a master/slave
set-up similar to that required in bayed
enclosure systems for optimum operating
results.
Technical description:
The master-slave layout facilitates common activation and deactivation via door
limit switches, parallel activation and
deactivation via a temperature setpoint,
and common collective fault signals and
temperature logging, eliminating the need
for intricate wiring.
RiDiag II for
Comfort Controllers
RiDiag is a diagnosis tool for the operating
conditions of Comfort controller-regulated
air conditioners. By connecting a PC, it is
possible to retrieve error messages, temperatures and capacity utilization levels of
the air conditioners.
The system includes integrated temperature measurement from four sensors in the
air conditioner, and also features graphical
representation of the temperature over
time.

HEAT DISSIPATION
Introduction
Modern production technology has become far more powerful since the advent of
electronics, particularly microelectronics.
However, as electronic components
become increasingly miniaturized and the
packing density in enclosures and electronic housings increases, these complex
systems have become more sensitive to
external factors such as dust, oil, humidity
and temperature.
This is critical, since the failure of electronic components inevitably leads to the
shutdown of entire production lines. The
resulting costs can be astronomical.
Heat in particular is the number one enemy
of sensitive electronics.
For semi-conductors, for example, a rule of
thumb states that for every 18°F/10°C
increase in the operating temperature, in
relation to the maximum permissible operating temperature, service life is halved.
On the other hand, high temperatures are
inevitable in enclosures because the
installed drives, transformers, power distribution components, programmable logic
systems and electronic components dissipate heat while in operation. This results in
“heat loss.”
the heat can be dissipated via air flow, in
closed enclosures, this can only be implemented via the enclosure walls.
The output-dependent temperature
fluctuations in an enclosure or electronic
housing can also be substantial. These
fluctuations cause stress, which in turn
leads to faster aging of the electronic
components and may cause premature
failure.
As mentioned above, correct operation
of electronic circuits and the problem-free
operation of entire production lines
depends substantially on the extent to
which the heat occurring in the enclosure
is dissipated to the outside.
Whether enclosures are open, i.e. air permeable, or closed, i.e. air impermeable,
has a decisive effect on the type of heat
dissipation. Whereas in open enclosures,

Basic terms
used in calculation
In order to select air conditioner components correctly, some calculations are
required. The following factors play a
significant
role:
.
Q V [watts]: Heat loss of the electronic
components
built inside the enclosure.
.
Q S [watts]: Thermal output absorbed or
dissipated by the effective surface area
of the enclosure (as specified by
VDE 0660, part 500). If the interior
temperature of the enclosure is higher
than the ambient temperature (Ti >Tu),
heat
. is dissipated by the enclosure
(Q S > 0). If the ambient temperature is
higher than the interior temperature
(Ti <Tu),. heat is absorbed by the enclosure (Q S < 0).
38
.
Q E [watts]: Required cooling output of
an air conditioner; this refers to the thermal output which the appliance must
dissipate
from the enclosure.
.
Q H [watts]: Required thermal output of
an enclosure heater.
Ti [°C]: Maximum permissible interior
temperature of the enclosure as prescribed by the manufacturers of the
electronic components. Generally
between + 35 °C and + 45 °C. Tu [°C]:
Maximum ambient temperature at which
performance of electronic components
is
. not degraded.
V [m3/h]: Required volumetric flow of a
filter fan unit.
A [m2]: Effective surface area of the
enclosure determined in accordance
with DIN 57 660, part 500 or VDE 0660,
part 500.
k [W/m2K]: Heat transfer coefficient of
enclosure:
Sheet steel ~ 5.5 W/m2K
Plastic ~ 3.5 W/m2K

Please note the following:
Where will the enclosure be sited
(dusty or oily air)?
What type of installation to
DIN VDE 0660, part 500 is your
calculation based on?
What type of ambient temperatures do
you anticipate, e.g. ambient temperature and humidity?
What is the heat loss Q v in the
enclosure?
What is the required maximum interior
temperature of the enclosure Ti ?
What are your protection category
requirements to DIN 40 050?
In the case of bayed enclosures, any
output radiated by the neighboring
enclosures must also be taken into
account.
The radiated output e.g. from the
environment into the enclosure must be
taken into account.
The air conditioners should always be
connected via door operated switches
in order to prevent excessive condensation.
The installation site of the enclosure and
the arrangement of the air conditioner
must be carefully selected to ensure
good ventilation of the external air
circuit.
The distance between the units and
from the wall should be at least 7.87˝/
200 mm.
In order to prevent an air short-circuit
in the internal circuit, the air inlets and
outlets should not be covered over.
To prevent increased condensation, the
enclosure should be well sealed on all
sides, including wireways and conduits.
Enclosure air conditioners
Practical tips
In all situations where optimum operating
temperatures are required inside an enclosure, even at high external temperatures, a
Rittal enclosure air conditioner can provide
the right solution. It is even possible to cool
the interior temperature of the enclosure to
well below the ambient temperature.
The favorable air flow arrangement of the
air inlet and outlet openings in the internal
and external circuits ensures optimum
air circulation inside the enclosure. This
sample calculation will show you a quick,
time-saving method for calculating a air
conditioner.
We are looking for a wallmount air conditioner.

Selecting an air conditioner
Consequently, an enclosure. air conditioner

is required at an ambient temperature
Tu = + 50°C and a desired enclosure

Using the performance diagram, we
selected an enclosure air conditioner
(SK 3305.100) to mount against a wall with
a continuous useful cooling capacity of
4250 BTU/1250 watts (see diagram).

Condensation and dehumidification
of enclosure air when using air
conditioners
An unavoidable side-effect of using
air conditioners is the dehumidification of
the enclosure’s interior air. As it cools
down, part of the humidity contained in the
air condenses on the evaporator coil. This
condensate must be discharged reliably
from the enclosure. The amount of condensate occurring depends on relative humidity, the air temperature in the enclosure and
on the evaporator coil, and the air volume
present in the enclosure.
The Mollier h-x diagram shows the water
content of air depending on its temperature and relative air humidity.
