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.

PARASOL Zenith

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.

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.

PARASOL Zenith

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.
