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 heat-
ing 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.
Parasol Zenith has variable k-factor setting and large air
flow range. The product is available both as a CAV
product with fixed k-factor and is easy to upgrade to a
VAV function with the help of different accessories. It is
also possible to order as a VAV variant from the factory
fitted with control or actuator for air flow control (0-10 V)
(see Parasol Zenith VAV b)

PARASOL Zenith b

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
slots (B). The high speed means that the surrounding air is
drawn in and mixed with supply air, which generates
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
further lowers the air velocity and lessening the temperature
difference 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.
Figure 4. Induction principle in Parasol Zenith
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.
As greater demands are made on being able to offer
customised office solutions and to easily change the floor
layout for new or existing tenants if changed needs arise,
it is important to take this into consideration as early as
the design phase. As this will minimise future costs for
rebuilding. Regardless of the scenario, new Parasol Zenith
gives - through its simplicity in terms of air flow range,
operation and commissioning - all the possibilities to find
this flexible and optimal solution.

Control variants
Parasol Zenith provides unique advantages with its slot
control and through this a large working range on the air
side.
Parasol Zenith is designed to handle a large air flow range
in one and the same product. This gives benefits such as
easy sizing and a straightforward product upgrade path.
In addition to quick and easy adjustment with the help of
a knob on the constant flow product PARASOL Zenith b,
there are two other designs:
WISE Parasol Zenith for the WISE II system
PARASOL Zenith VAV for stand-alone applications
(Launched week 17).
For more information, see the product sheets
WISE Parasol Zenith and Parasol Zenith VAV on
www.swegon.com.
You can also integrate Parasol Zenith as a pure CAV
product (without motorised damper function) in the WISE
system. This is done by choosing a WISE CU as a fitted
accessory. This gives additional flexibility to use wireless
technology and at the same time future-proof the product.
With the help of our upgrade kits the product can sub-
sequently be upgraded with a motor and e.g. face plate
with presence sensor and then turn into a WISE Parasol
Zenith with variable motorised control of the air flow.
Read more about our upgrade kits on page 26.

PARASOL Zenith b

In order to clarify the large work area of Parasol Zenith
we can compare the curves for cooling capacity/air
flow with the cooling requirements for seven different
types of rooms:
A+B Individual office room (1 person)
C+D Office for customer visits (3 people)
E, F, G, Conference room (4, 6, 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 diagrams 1 and 2, we can see that the product variants
can handle all types of rooms. All that is required is to
adjust the slot openings as required.
You can also see that the products can 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 working range
The work area related to the smallest to the largest air
flow in one and the same product is very large for
Parasol 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
possible by Parasol Zenith being equipped with slots for
versatile and easy air flow adjustment. This also gives the
following advantages:
• Fewer variants through larger air flow range/
k-factor area
• Products with easy k-factor setting on site for quick
start of the build
• Simple commissioning

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 aerodynamic designed dual outlets in combination
with the integrated damper and the placement of the slot
openings, PARASOL Zenith distributes the air with very
good adhesion to the suspended ceiling (Coanda effect)
even at low driving pressure and you do not need to place
a commissioning damper in front of the product.
If you still, for example in large conference rooms with up
to four products, want to install a VAV damper in front,
the duct pressure, dependent on the air flow rate, can be
lowered down to 20 Pa.
Figure 7. Double outlets.
All 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.
ADC can also be used to reduce the throw length. By setting
ADC to L-shape, the distance between two units can be
reduced to a minimum and still ensure good comfort.
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 direction of the air can be easily adjusted and gives
future-proofing, offering a simple measure on location for
any change to the furnishings and layout. The ADC does
not affect the sound level or static pressure at all.

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 extract 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.
