PARASOL Zenith

Comfort module PARASOL Zenith
Our latest addition to the Parasol family have be developed,
with as few variants as possible, to handle large variations
in the air flow rate, cooling load and heating load. This is
to enable tenant adaptations without the need of making
extensive changes in the system as a whole.
The increased cooling capacity also enables a lower duct
pressure or a higher cooling water temperature can be
used, which saves energy and even improves room com-
fort further.
PARAGON Zenith is available in the following variants:
Variant A: Supply air and waterborne cooling,
(1200 and 1800)
Variant B: Supply air, waterborne cooling and heating
(1200)
Installation: Flush mounting for suspended ceilings
Range of Application
Parasol Zenith is ideal for use as a standard application in
such premises as:
• Offices and conference rooms
• Classrooms
• Hotels
• Restaurants
• Hospitals
• Shops
• Shopping centres
Function
Parasol Zenith is a 4-way air discharge comfort module with
induction function. Exactly as in a climate beam, the supply
air is used to operate the cooling and heating function of a
central air handling unit and therefore does not include an
integrated fan or other moving parts. This gives very quiet
operation and minimal maintenance requirements. Unlike
a 2-way air discharge climate beam, air distribution to the
room occurs from all 4 sides of the unit, which means as
large areas of the ceiling as possible are used to spread the
air, thus ensuring comfort in the occupied zone.

Market-based module dimensions
The order range includes module dimensions to fit the
standardised ceiling measurement c-c 600, 625 and 675
mm. In addition, there is a mounting frame for drywall
ceilings and ceiling solutions of the clip-in-type, for exam-
ple, Dampa and FineLine. In order to guarantee a good fit
in T-bar systems, we recommend T sections with a width
of 24 mm.

Induction principle
Primary air (A) from the air handling unit provides Zenith
PARASOL with supply air via a supply air duct and builds
up positive pressure in the unit's plenary.
The supply air is forced out at high speed through small
nozzles (B). The high speed means that the surrounding
air is drawn in and mixed with supply air, which gener-
ates negative pressure above the unit’s integrated heat
exchanger (C). Room air (D) is continuously drawn up
from the room through the water-based heat exchanger
where, if necessary, it is cooled or heated before it mixes
with the supply air.
The mixed air is then distributed to the room via aero-
dynamically designed outlets. The outlets are designed
to ensure that the distributed air follows the suspended
ceiling by utilising the so-called Coanda effect (E). The
supplied air is then mixed with additional room air, which
reduces air velocity and lessening the temperature differ-
ence before it reaches the occupied zone.
The proportion of recirculated room air drawn through
the heat exchanger is typically about 3-5 times the pro-
portion of primary air, i.e. if 20 l/s supply air comes from
the air handling unit, then approximately 60-100 l/s room
air will pass through the exchanger and be tempered.
Condensation-free cooling
Parasol Zenith has been developed to work condensation-
free and therefore requires no drainage system or filter.
Normally inlet temperatures between 14-16 °C are used
for the cooling water.
High comfort – today and tomorrow.
A good indoor climate is characterized by good air quality
and the correct room temperature without draughts and
noise. Different requirements are made on air flow, cool-
ing capacity and heating capacity depending on the type
of building in question and how this will be used. If you
are sure that the initial floor plan will never be changed
you do no need to take into account future changes.
However, if it is likely that the floor plan will change, you
need to take this into account at an early stage to mini-
mise the high costs of subsequent retrofitting. No matter
which scenario you imagine, Parasol Zenith gives you the
possibility to find the right solution.

PARASOL Zenith

In order to clarify the large work area of Parasol Ze-
nith we can compare the curves for cooling capac-
ity/air flow with the cooling requirements for five
different types of rooms:
A Individual office room (1 person)
B Office for customer visits (3 people)
C Conference room (4 people)
D Conference room (6 people)
E Conference room (8 people)
The individual office and the office for customer visits are
assumed to be placed at the façade, while the conference
room is assumed to be placed on the floor’s inner zone.
In diagram 1, we can clearly see that the same product
can handle all types of rooms. All that is required is that
the nozzle strips are adjusted to open or close the nozzles
as needed.
You can also see that the products give a higher cooling
capacity than the demand. This allows several options:
• Use the full capacity to quickly correct the deviations in
room temperature
• Lower the driving pressure in the supply air duct and
save fan energy
• Increase the supply flow temperature of the cooling
water and save energy (chiller)

Large operation range
The work area related to the smallest to the largest air
flow in one and the same product is very large for Para-
sol Zenith. In practice this means that one and the same
product can handle a variety of room types, by being
adjusted as required. The large work area is made pos-
sible by Parasol Zenith being equipped with dual nozzle
rows and thus more available nozzles. This also gives the
following advantages:
• Individually adjustable air flow on all four sides of the
unit
o Move the air where you want
• Possible to maintain the same k-factor in different
distribution patterns
o No need to readjust the damper
• Nozzle setting of the k-factor (small step)
• Fewer variants
o One Parasol Zenith serves many needs

Comfort guarantee
As previously described, Parasol Zenith has 4-way air
distribution, which gives low air velocities in the occupied
zone. Distributing the cooled air over a large ceiling area
creates the low air velocity. The comfort module’s closed
design with a circulation opening for return air in the face
plate of the module also contributes to its advantageous
mixing performance.
With its dual nozzle rows in combination with the aero-
dynamically designed double outlets PARASOL Zenith dis-
tributes the air with very good adhesion to the suspended
ceiling (Coanda effect) even at low driving pressure. The
duct pressure can then, depending on air flow rate, be
lowered down to 20 Pa. This saves fan energy while the
noise level is kept to an absolute minimum.
Figure 5. Double outlets.
All the comfort modules contain ADC 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 ADC sections with nine 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°.
This provides great flexibility and can be adjusted without
having to affect the system as a whole. The sound level
and the static pressure are not at all affected by the ADC.

Change of layout - Example
Figure 9 shows an example of the floor plan of a build-
ing with offices and a conference room. Assume it is
arranged as illustrated and the that the highlighted rooms
were originally used as a group rooms or small conference
rooms. New demands on the premises in the form of
alternative usage or other activities may mean that some
of the rooms need to be partitioned off as in figure 10,
for example, to create small individual offices. Adjustable
air flow through adjustable nozzles, high k-factor range,
air deflectors ADC and 4-way air distribution mean that
no new installations are needed, but the same products
can be used with other settings.
The large working area permits great opportunities to
control the air flow rate individually on all four sides of
the Parasol Zenith. At 80 Pa total pressure, a 1200-size
can supplying anywhere from 0 to 11 l/s on one short
side and between 0-34 l/s on one long side (Figure 11).
A 1800-size can supplying anywhere from 0 to 11 l/s per
short side and between 0 and a full 42 l/s on one long
side (Figure 12).
Figure 9.
Figure 10.
The direction and rate of the air flow can be easily opti-
mised using the Swegon ProSelect sizing program avail-
able at www.swegon.com. You can then easily export
CAD models with the current settings from ProSelect to
MagiCAD or other CAD programs.

Design
The face plate of the Parasol Zenith is always “flush”, i.e.
always in line with the suspended ceiling which gives a
stylish and discreet installation. The double outlets means
that there is no need to lower the face plate for high air
flow rates, maximum capacity (induction) is still achieved.
The face plate on PARASOL Zenith is available with four
different perforation patterns that make it easily adapta-
ble to suit different types of ceiling components, e.g. light
fittings and axtract air diffusers that share the surface
of a suspended ceiling. A suspended ceiling containing
different types of perforation patterns can otherwise be
experienced as disturbing to the eye. As standard, the
face plate has round perforations arranged in a square
pattern. Other patterns are of course available on special
order. For further details, get in touch with your nearest
Swegon representative.

Easy installation
PARASOL Zenith is built on a platform with very compact
dimensions. In many cases the design permits installation
in the existing T-bar system without the need of disman-
tling, provided that there is at least 300 mm of space
between the suspended ceiling and the joists.
The slim design and lightweight result in simpler handling,
especially when handling the products on the site, which
gives less handling damage and a better working environ-
ment. Parasol Zenith’s compact units fit most common
modular dimensions and fit most suspended ceiling
system on the market.
As standard the units include four mounting brackets.
These are adjustable +/- 20 mm in both directions and in
doing so create the adjustment range normally required
during installation.
Figure 17. Installation in existing T-bar system
Rooms with elevated hygiene demands
PARASOL Zenith is available as a variant with a fold-out
coil for easy access to the complete heat exchanger.
A dust-free environment is especially important in rooms
with elevated hygiene demands.
Over time large amounts of room air pass through Parasol
Zenith’s coil (heat exchanger). Dust particles, which fasten
on the coil, not only result in less capacity, but also fail to
comply with the hygiene requirements that apply to the
room.
Parasol Zentih has, as an option, the possibility of fold-out
coils to meet these requirements.
In addition to normal cleaning, by wiping off dust from
the white painted surfaces exactly as you clean other sur-
faces in the room, the option of more thorough cleaning
is now possible.
1. It is recommended to vacuum clean the coil several
times a year. More frequently in a room with a lot of
textiles and a high rate of air change. The face plate
is opened or dismantled to gain access to the coil, see
figure 18.
2. In environments with elevated hygiene demands
additional cleaning of the comfort module may be
a requirement. The use of flexible connection hoses
and the possibility to fold out the coil permits clea-
ning of the top of the coil in these instances, see
figure 19.
Figure 18. Removing the face plate to access the coil
Figure 19. Removing the face plate and folding out the coil for
accurate cleaning in the event of high hygiene requirements.
Note! requires the product to be ordered with the accessory, fold-
out coil, and that flexible connection hoses are used on the water
side.
