HALL-MX:
OUTSTANDING AIR QUALITY. ALWAYS.
In multi-screen cinemas, where the various rooms can be
crowded to a lesser or greater extent, air quality is a fundamental
requirement of spectators.
This quality greatly depends on the capacity of the airconditioning
system to optimise temperature and humidity levels
whilst ensuring silent running.
With this in mind, Climaveneta has developed a simple
and reliable system for delivering constantly clean and healthy
air at optimal levels of energy efficiency. Thanks to a built-in heat
recovery system, the new HALL-MX independent conditioning
units ensure low installation and running costs whilst providing
the required environmental conditions.
Designed for cinemas, shopping centres, restaurants, conference
halls, open-space offices, gyms, sports centres and discos,
the new Climaveneta HALL-MX range, featuring special attention
to design and accurate selection of materials, provides constantly
clean and healthy air whilst offering energy savings of up to 20%
compared with other systems.

SUPERVISION
SYSTEM.
The FWS supervision
system allows the system
to be monitored without
having to install any
additional software onto the
dedicated supervision PC's
as standard applications
(Internet Explorer,
Netscape,...) that are
normally already installed
on PC's are used.

MAIN ADVANTAGES.
Structure
The structure comprises a base made from
hot-galvanised, epoxy powder-painted sheet steel
profiles.
The frame and outer panelling are made
from aluminium alloy which offers total protection
from atmospheric agents.
The panels are easy to remove and allow easy
access to internal components.
The area in contact with the treated air is made
from double-wall (42 mm) sandwich panelling in
galvanised sheet metal for the delivery fans and
expansion coil, in galvanised sheet metal (internal)
and aluminium (external) for the other components,
separated by an insulation layer of hot-injected
polyurethane with an average density of 45 kg/m 3 .
Cross-section of Sandwich panel
Outstanding air quality.
The incoming air filter sections (EU4),
the banks of bag filters (up to EU7) and the CO 2
probe provide excellent treated air quality even
for highly crowded areas containing high levels
of contaminants.
CO 2 probe
All the surfaces in contact with the treated
air are made from perfectly cleanable metal,
hence guaranteeing hygiene, internal air quality
(IAQ) and compliance with Legislative Decree
626/94 regulating occupational health and safety.
Static heat recovery
unit
Energy saving.
As the system is required to condition high flows
of external air, the presence of an air/air plate-type
static heat recovery unit effectively reduces running
costs as well as complying with DPR (Decree of the
President of the Republic) n° 412: “Design rules for
the purposes of energy saving”.
The greater the temperature difference between
the external air and ambient return air flows which
are combined inside the heat recovery unit,
the more thermal energy can be recovered.
Peak efficiency levels lie at around 75%.
The ambient return air and the external air flows
are hermetically separated and cannot mix, hence
totally guaranteeing the quality of the treated air.

Minimum space, minimum impact.
Its particular aesthetic and structural compactness
makes it possible to install HALL-MX anywhere
with a minimum of environmental impact.
Easy maintenance.
Large access panels make maintenance particularly
simple, while ad hoc construction solutions make it
easy to access and remove components requiring
periodic cleaning.
Easy installation.
After positioning the unit, it is now ready
to be connected to the ducts. During this operation,
the electrical connections can also be completed,
thereby allowing assembly to be performed rapidly
along with ventilation testing and calibration
of the air circuit.
Wide range of accessories:
• additional heating
- hot water coil
- heating element,
• humidification
- immersed electrode humidifier,
• dirty filter detector,
• gas heating unit.
• enthalpic free cooling.
Free-energy.
In normal air-conditioning units, the rooms are cooled
or heated by a cooling circuit which uses electricity
to power the relative compressors and fans.
In spring and autumn, in winter with crowded rooms
or in summer during the coolest hours
of the day, the external air may very well have
the same temperature and humidity conditions
as those required for the rooms.
If these external conditions are suitably used, they
can respect internal rated conditions by simply
keeping the fans working. Stopping the cooling
compressors makes drastic reductions in power
consumption and therefore saves a large amount
of money.
In particular, if the external air is fresher than the
internal air, the room can be cooled by directly
delivering the suitably filtered external air without
having to use the cooling section (Free- Cooling).
Similarly, the rooms can be heated when external air
conditions allow (Free- Heating).
In both cases, the modes are automatically activated
by the electronic control unit on board the unit which
is programmed to keep the system as efficient as
possible and minimise running costs.
4

Ease of selection and choice
of the most suitable unit.
Units sized and tested to ensure
optimal comfort, air quality,
temperature, humidity and silent
running for multi-screen cinemas
depending on the number
of seats and an external airflow
of 8 l/s per person.

FWS SUPERVISION. (optional)
The FWS supervision system allows the system
to be monitored without having to install any
additional software onto the dedicated supervision
PC's as standard applications (Internet Explorer,
Netscape,...) that are normally already installed
on PC's are used.
The FWS module is generally installed near the
PC.The units communicate with the module along
an RS 485 local network for a maximum distance
of 1,000 metres, while the module and the PC
either communicate directly or along an Ethernet
network (LAN).
The supervision PC shows the following information
for each unit:
- unit status and alarms
- main temperature settings
- set-points and operating mode
- compressor status and operating hours
The following can be set and modified:
- operating mode
- room washing override
-rapid start-up up override
- weekly/daily programming with five time bands.
If the supervisor is disabled, each unit can work
normally using the on-board thermoregulation
device.
Access to the supervision programme is reserved to
users with Login and Password.
A customided access profile may also be defined for
each user to allow them to operate in pre-selected
and well-defined areas.
The user interface has been organised like
a website with dynamic pages that can be accessed
through links. The information on each page
is organised in the form of a table.
On request, the pages can be customised with
photos, diagrams and descriptive texts, or links
to screens showing details of the units.
If the FWS unit is connected to the Internet,
the supervision software can be updated
or modified from a remote PC.
For equipment not supplied by Climaveneta (e.g.
exhaust fans, split,...), the FWS supervision system
allows commands to be made through volt-free
contacts and temperatures to be read through NTC
probes.
It is also possible to configure FWS to report any
alarms directly to “Climaveneta Service” by e-mail
and/or SMS.

OPERATING METHOD.
Standard operation.
It may be necessary to cool or heat a room according
to temperatures and crowding levels. Depending on
requirements, the unit will automatically operate in
the cooling, dehumidification or heat pump mode.
Considering that using external air alone
is extremely expensive, a varying blend of external
air and ambient return air is used.
To guarantee the quality of the air in the room, some
of the inlet air is constantly discharged externally.
Flow is adjusted according to the level of crowding
and, consequently, the number of people in the
room. This value is measured by a CO 2 probe and
processed by the control unit.
The external air used in the blend is pre-heated or
pre-cooled using a static heat recovery unit which
makes it possible to significantly reduce energy costs
connected with the treatment of external air.
The recovery unit transfers heat between the
ambient return air and the external air without it
being possible for the two floes to contaminate one
another and totally free of charge as no power is
required. The external air leaving the heat recovery
unit and the ambient return air make up the flow
that will be sent to the room after final treatment is
performed by the cooling circuit treatment bank.
For special requirements, it may be necessary to
adjust the humidity level in the room separately from
the temperature.
To satisfy these needs, the dehumidified and
therefore thoroughly cooled air goes through a postheating
coil where part of the condensation gas from
the refrigerating system circulates, and then it is
released into the room. As a result, the dehumidified
air is heated free of charge, thus providing an
elevated level of comfort at low power costs.
The static heat recovery unit is an extremely safe
and reliable heat exchanger with no moving parts.

The unit can be fitted with a direct steam humidifier
in order to maintain constant control of the internal
humidity conditions also during winter.
The quantity of vapour is constantly adjusted
according to the real requirements of the system.
Start-up. Used ambient air only.
This heats the room rapidly by circulating
the same air. This function is used after the room
washing function when the room is empty and offers
considerable energy saving.
Room washing.
This rapidly refreshes the ambient air.
External air is introduced into the room
for a pre-set time while the used ambient
air is totally expelled.
