Parasol EX Comfort modules
Function
Parasol EX is the name of the product family of comfort
modules for suspended installation. The modules are designed to supplement one another and provide optimal room
comfort.
4-way air distribution in combination with Swegon ADCII
(Anti Draught Control), creates a maximized mixing zone
and minimizes the risk of draught issues. The Parasol EX is
designed for distributing air slightly upward. This gives the
chilled air more space to mix with the room air before it
reaches the occupied zone.

Flexibility
The easily adjustable nozzles in combination with Swegon
ADCII offer maximal flexibility if changes in the room
layout become necessary. All the sides can be set independently of one another so that the comfort module can
distribute more or less air and simultaneously discharge air
in whatever direction desired in the room.
Design
By styling straight lines and sharp edges, Swegon architects have created a timeless design that fits in well in
most room decor together with other installations in the
room.

1 = Primary air
2 = Induced room air
3 = Primary air mixed with cooled room air
Draught-free indoor climate
Utilizing four directions for discharging chilled air into the
room also maximizes the size of the mixing zone. In practice, this effectively mixes the chilled primary air with the
room air before the air reaches the occupied zone. When
the mixed air reaches the occupied zone, it has attained a
temperature that reduces the risk of draught. The special
design of the outlet discharges the distributed air slightly
upward, which to a great extent contributes towards both
reducing air velocity in the occupied zone and ensuring
that the chilled air is mixed with room air before it reaches
the occupied zone. This upward discharge provides a distribution that is not dependent on nearby surfaces to create
a coanda effect. In a simple operation, the ADCII, included
as standard, enables you to move the deflector groups to
direct the airflow in whatever direction you desire.

PARASOL EX
Supply air module
A comfort module for supply air only is available (variant
C – without coil) to supplement certain types of rooms
where the occupants need a great quantity of air, but
only a smaller amount of water-based cooling energy.
This applies, for instance, to certain conference rooms or
the inner zones in large rooms. To avoid over-sizing, it is
common to combine units with cooling function and units
with supply air function only. Since the supply air variant
is also designed according to the induction principle, it is
possible to discharge supply air substantially below room
temperature and yet not need to think about possible
reheating, which may be required in combined systems
with chilled beams and air diffusers. The rate of induction
varies depending on pressure and flow conditions but
lies generally in the range of 3-5 which means that if you
add 30 l/s, 3 to 5 times as much warm room air (90–150
l/s) will be induced. The mixed air then has a substantially
higher temperature than the temperature of the supply
air, which reduces the risk of draught in the occupied
zone.
Figure 5. Nozzle adjustment
PARASOL EX
Another advantage of the supply air module is, that it
operates with the same duct pressure as the modules
with coil. In other words, there is no need to throttle the
pressure in any duct branch more than necessary. Instead
of incorporating a coil into the supply air module, the
module has an induction control with punched nozzles
that is designed to provide the same rate of induction as
the units with coil. This makes it possible to use Swegon
ProSelect the dimensioning program for sizing throw
lengths, even for supply air modules. If shorter throw
lengths than standard are desirable, certain openings can
be plugged to reduce the free area in the induction control, to reduce the percentage of induced room air. The
capacity of the primary air is never affected by an increase
or decrease in the rate of induction.
High capacity
The high performance and small overall dimensions of the
Parasol EX units make them ideal for replacing awkwardly
large products, without sacrificing comfort.
Simple to adjust
Built-in nozzle control makes the Parasol EX very flexible.
The product can easily be adapted to current requirements by increasing or decreasing the airflow. A large
room can be converted into separate office rooms without influencing the room climate. A partition wall can
be installed in close proximity to any of the product’s
sides. The only measure required for preventing possible draught is to optimize the portion of air distributed
from each side of the comfort module. The end result is
a system that will provide excellent performance throughout its functional life.

PARASOL EX
ADC II
All the comfort modules contain ADCII as standard. ADC
stands for Anti Draught Control, which enables you to set
the diffusion pattern of the air being distributed to avoid
risk of draught. A number of ADCII sections with four air
deflectors per section are arranged on each side of the
unit. Each section is adjustable from a straight setting to
40° air deflection to the right or left in increments of 10°
(see Figure 6). This provides great flexibility and can be
easily adjusted without at all having to affect the system as
a whole.
The sound level and the static pressure are not at all affected by the ADCII. The water capacity is reduced by 5 - 10%
if the ADCII is adjusted to "fan-shape".

Range of Applications
Optional perforation patterns
The Parasol EX is ideal for use as a standard application in
such premises as:
The face of the unit is available with three different perforation patterns, so that it can be adapted to suit different
kinds of ceiling components, e.g. light fittings and exhaust
grilles. This avoids the clutter effect of mismatched components. Other patterns are of course available, on special
order. For further details, get in touch with your nearest
Swegon representative.

Location
Since each side of the Parasol EX is individually adjustable
to provide the appropriate airflow, the comfort modules
can be positioned anywhere in the room. Whether they
are located at the front edge, centre, rear edge or symmetrically in the room is of no importance. In rear edge
solutions for separate office rooms, for instance, the unit
can be installed directly against the corridor wall. The
only operation that needs to be done is to reduce the
volume of air distributed towards the corridor wall and to
open on the three other sides more (see Figure 9). This
is of benefit in comparison with other rear-edge solutions, because you can make use of the partition walls to
increase the air mixing zone. This provides low air velocities and a healthy room climate.

Room control
Reliable, well-performing control equipment is required
for maintaining uniform room temperature and ensuring a
healthy room climate. Swegon LUNA room control equipment is designed to minimize temperature fluctuations in
the room, by continuously modulating the pulse width of
signals transmitted to the actuator. This function makes it
possible to use a thermal actuator to quickly compensate
possible sudden increases or decreases in heating loads in
the room. The digital processor is easy to reconfigure and
this offers great flexibility. The operations in a premises are
likely to change over time. For example an open plan office
can be split into small office rooms. In this case the settings in the controller can easily be changed to suit the new
situation.
More detailed information about the room control equipment is available in a separate product datasheet on our
website: www.swegon.com.

To connect the air
The Parasol EX is supplied with the connecting piece on
the same side as the water connections.
There is a cover on the opposite side, which on the Parasol
EX can only be used as a cleaning door. The pipe kit and
enclosures will not fit if you use the cleaning door as an
air connection.
To connect the water
Connect the water pipes using push-on couplings or clamping ring couplings. Do not use solder couplings to connect the water pipes. High temperatures can damage the
unit’s existing solders.

Corrected capacity – water flow
Standard
Different water flow rates to some extent have effects on
the capacity output. By checking calculated water flow
against Chart 2 or 3, the capacity indicated in Tables 3-5
may need to be slightly adjusted up or down.
The cooling capacities have been measured in accordance
with EN 15 116 and have been converted for constant
water fl ow according to Diagram 2/3.
Calculating Formulae - Cooling
Below are some formulae that enable the user to calculate
which comfort module selection is best-suited to the

Nozzle setting
k-factor (C.O.P.)
The unique built-in nozzle control in the Parasol EX
means that each of the four sides can be set individually.
Depending on the unit’s location and the room’s primary
air requirement, the primary air can be guided in alldesired directions. The direction of the airflow can be easily
optimized using the Swegon ProSelect sizing program
available at www.swegon.com.
Each nozzle setting has a specific k-factor. A total k-factor
for the unit can be determined by adding together the
k-factors for the nozzle settings on each side. The relevant
k-factor (C.O.P.) for optimized nozzle setting can also be
obtained in ProSelect.
All the units held in stock are preset to the same nozzle
setting on all four sides. The airflow direction can be
easily adjusted when installing the unit, using the adjustment tools supplied with the unit. This provides logistic
advantages since the fitter does not have to take specific
room markings into account.

To specify optimized nozzle settings, always begin from
the side nearest to the left of the water connections. From
there, specify side after side in counter-clockwise order. See
Figures 19-21. If you like, you can order the units preset
from the factory (does not apply to units held in stock).

The cooling capacity of the primary air can be calculated
using the following formula:
Pl = 1.2 x ΔTl x ql
Pl = 1.2 x 6 x 432 = 3110 W
The remaining cooling capacity that must be provided by
water-based cooling will then be 9600 – 3110 = 6490 W.
From Table 5 we find that a Parasol EX 1290 in the high
flow version with nozzle setting HHHH can distribute 36

The cooling capacity of the water can be read from the
same table: 612 + 682 / 2 = 647 W per unit (interpolate
between ΔTmk 8K & 9K).

647 x 12 = 7764 W which is 1274 W more than the cooling load. To avoid over-sizing, you can decide to replace
two of the units with supply air modules that do not
contain any coil. This will instead provide a total cooling
capacity on the water side of 647 x 10 = 6470 W which is
on a level with the cooling load.

The cooling or heating capacity of the air
Heating
Heating function
Heating spaces, with air heated above room temperature,
discharged from the ceiling, is a good alternative to conventional radiator heating solutions. The benefits achieved
include lower installation costs, simpler installation and
perimeter walls free from piping and radiators. Regardless
of the type of heating system installed, it is important to
consider the operative temperature in a room.
Most people are comfortable when the operative temperature in winter is in between 20–24°C, and for most quality requirements 22°C, is usually regarded as the optimal
level. This means that for a room with a cold perimeter
wall, the air temperature must be higher than 22°C to
compensate for the chilling effect of the wall. In new buildings with normal insulated perimeter walls and normal
standards of window glazing, the difference between the
room air temperature and the operative temperature is
small. But for older buildings with poor windows, it may
be necessary to raise the air temperature to compensate
for the chill from perimeter walls.

PARASOL EX
The Parasol EX is optimized for distributing supply air without help from the coanda effect and can discharge air
in a variable diffusion pattern thanks to the built-in ADCII,
that also further increases the mixture of supply air into
the room air. The Parasol EX therefore supplies heated air
to the room with a turbulent jet that quickly mixes itself
with the room air. This speeds up the process of cooling
down the heated air so that it more easily can reach
down to the occupied zone. Different operating scenarios
can be simulated easily using the Swegon ProClim Web
software to calculate the heat balance and determine the
room air temperature and operative temperature. Supplying heated air from the ceiling results in some stratification of the air. With a maximum supply temperature of
40°C, the stratification is non-existent, while at 60°C it
can be around 4 K in the occupied zone. This only applies
during the warming-up phase, when the room is unused
and there is no internal load. When the room is being
used and lighting, computers and people are in present,
the stratification is reduced or disappears depending on
the heating load. Laboratory studies, computer simulations and reference projects all show that a good indoor
climate will be achieved by means of the PARASOL EX
comfort module whatever the time of year.
Pl = 1,2 · ql · ΔTl

PARASOL EX
Calculation Example - Heating
In the same room as in the example for cooling, there is a
also a heating load of 50 W/m2. This produces a heating
capacity load of 50 x 8.0 x 20.0 = 8.0 kW. The primary air
flow must be the same as in the summer scenario, 432 l/s
which result in 36 l/s and unit.
Design room temperature (tr) 22°C, heating water temperature (flow/return) 50/40°C and the primary air temperature (tl) 20°C produces:
ΔTv = 10°K
ΔTmv = 23°K
ΔTl = -2°K
Solution
Heating
The primary airflow of 36 l/s in combination with the
primary air temperature of 20°C produces a negative
impact on the heating capacity: 1.2 x 432 x (-2) = -1037
W. The heating capacity requirement from the heating
water is thus increased to 8000 + 1037 = 9037 W. From
Tabell 10 at ΔTmv = 23°K and primary air flow 36 l/s we
produce a heating capacity of P v = 1266 W. To meet the
total heating load we need 9037 / 1266 = 7.1 units which
then can be rounded upward to 8 units. Parasol EX 1290
with heating function.
PARASOL EX
Heating Water
With a heating requirement of 9037 / 8 = 1130 W per
unit and ΔTv = 10K, we obtain the required water flow
from Chart 5: 0.027 l/s. The pressure drop for the heating
water is calculated on the basis of a water flow of 0.027
l/s and pressure drop constant kpv = 0.0213, which is
taken from Table 10. The pressure drop will then be: Δpv
= (qv /kpv)2 = (0.027 / 0.0213)2 = 1.6 kPa.
