AERMEC S.p.A

Aermec RePuro is the innovave soluon which oers air renewal with 90% eciency and its purica-
on at the same me through Plasmacluster, this device is a standard equipment on each unit
Aware of the importance of air renewal and puricaon, AERMEC RePuro, has been designed in order to
oer the best performances compared to the products currently available on the market, we can high-
light:
1 – Very high heat recovery eciency
Caused by the countercurrent air/air exhanger
The “countercurrent exchanger” technology permits to reach recovery eciency greater than 90%. Con-
sequently the fresh air gets in at a very similar temperature to that of the room: this performance is ab-
solutely greater than a tradional recovery mixed ow unit.
2 – Minimized energy consumpon
Caused by inverter driven fans
The employ of high eciency inverter technology, in line with commission regulaon (EU) No 327/2011,
grants the maximum exibility in air ow and avalable stac pressure regulaon for each system. The fans
eciency is already in line with the stated values in commission regulaon of 2015.
3 – High quality of the air
Because of Plasmacluster device
Plasmacluster technology is based on the physical principle of ions generaon which aract the water
molecules of the air creang aggregates called “clusters”. The “clusters” completely surround the danger-
ous microparcles of the room, and consequentely removing their harmful eects on people. This creates
a further ltraon eect compared to the standard mechanical lters currently available on the market.
4 – High availability of accessories
The best tecnology of RePuro involves an high availability of accessories so this unit can be perfectly inte-
grated in each kind of system.
5 – User interface
simple in the ulizaon and elegant shape
All RePuro units are complete with a wall hung user interface with capacive touch LCD screen coming
from the aesthecally pleasing VMF-E4 which won the “Good Design” award in 2010.
6 – Only one system for each comfort need
through the integraon of RePuro with Aermec VMF system
Compared to a stand alone tradional mechanical venlaon system, RePuro has been designed to be
part of (oppure to be integrated in) the VMF system network as the component dedicated to the air re-
newal and puricaon.
Starng from today Aermec oers a complete system which allows to control each need of:
- Heang
- Condioning
- Domesc hot water management
- Air renewal and puricaon
granng the overall best system eciency beyond an opmal result ensured by an unique manufactorer.

Benzene
Produced from external trac or from proximity to pet-
rol staons, chemical industries, and steelworks. With
garages joined to dwellings it can move towards internal
rooms. It can be released from cooking and heang sys-
tems.
Elevated concentraons can cause death in a maer
of hours. Exposure by connuous inhalaon at lower
levels mainly aects the blood producing illnesses of
anaemia, lymphopenia and leukemia.
Carbon Monoxide
(CO)
Is found in external air and is produced by the bad
combuson of endothermic engines. In internal
spaces it can be caused by an incorrect installaon,
a defect, or poor maintenance of cooking systems or
heang systems burning fossil fuels.
High concentraons (>80%) cause death by cardiac
arrest. Exposure by connuous inhalaon at lower
levels can cause memory loss, psycho-emove al-
teraons, asthma, and heart failure.
Formaldehyde
Mainly produced within internal environments. It is
generated by tobacco smoke, heang systems, burn-
ing candles or incense. It is also produced by construc-
on materials (resins applied on wooden furniture and
insulang materials) and is frequently used in cleaning
products (it is a strong bactericide).
Provokes irritaons of the upper respiratory system.
In more serious forms it causes carcinomas.
Nitrogen dioxide
(NO2)
Derives from combuson processes (the main pro-
ducer is vehicular trac). Within internal environ-
ments this substance is produced from tobacco
smoke and combuson (from any combusble);
combuson being the worst and major producer of
this gas.
Can cause eczema, throat and ear infecons and
leads to increased allergen sensivity in children.
In adults it can contribute to the increase of respira-
tory symptoms (such as asthma).
Polycyclic aromac
hydrocarbon (PAH)
Produced from combuson at high temperature.
Comes from vehicular trac in the external air. Inter-
nally it is produced from cigaree smoke, re places,
cooking systems, smoke from candles and incense.
Is a carcinogenic substance.
Radon
Is naturally produced from the radioacvity of certain
rocks. There can be traces in some construcon mate-
rials and in the water.
Is a carcinogenic substance (lung cancer).
Trichloroethylene
Is produced in industrial environments (cooling sys-
tems), dry cleaners, print works (prinng ink), paints,
texle prinng. In internal environments it comes
from printers, fax and photocopy machines, as well
as cleaning products and furniture paint.
Is a carcinogenic substance (liver and lung tumours);
other symptoms involve deformity of the eyes and
heart.
Tetrachloroethylene
Is a solvent agent used in industrial applicaons
(steelworks, texle industries, inks and cleaning
products). In internal environments it can be pro-
duced from adhesives, perfumes, stain removers,
fabric nish, water repellents, wood detergents and
detergents for vehicles.
In various concentraons aack eyes, kidneys, liver,
lungs and mucous membranes of the skin, causing
renal, liver and reproducve systems failure. A cor-
relaon has also been shown with oesophageal and
cervical cancer.
4. INTRODUCTION TO RESIDENTIAL VENTILATION AND THE AERMEC RePuro TECHNICAL SOLUTION
4.1. 
In terms of preventing health risks deriv-
ing from ambient factors it is only in recent
years that more attention has been paid to
internal air pollution; the quality of the en-
vironments in dwellings or schools, techni-
cally defined as indoor.
When we think about the air that we
breathe in a residence in a traditional ur-
ban centre, compared to that outdoors,
we conclude that the outdoor air quality
is worse.
This is not always the case and the oppo-
site could be true.
On average the internal air of a domestic
environment is more polluted than that
outdoors.
Due to infiltration caused by the opening
of doors and windows the air breathed in-
doors is the same as outdoors.
In practice the result becomes:
air in house
=
external air + internal pollutants
Recently constructed dwellings are de-
signed to minimise the infiltration of air,
and as a consequence the pollutants pro-
duced internally remain there.
Internal and external pollutants are of this
nature:
- chemical
- biological
- physical
The following table shows the main pollut-
ants, where they come from and what ef-
fects they provoke or cause (source: World
Health Organizaon – (WHO) GUIDELINES
FOR INDOOR AIR QUALITY – 2010).

10 IREPPY - 1404 - 4238051_01
The chemical-physical pollutants, as
shown above, are not the only elements
that contribute to the pollution of the in-
door environment.
There are also biological pollutants (mites,
bacteria, virus, moulds, dirt from animal
origin) that provoke or cause chronic res-
piratory symptoms. A collection of studies
on this subject is published in DAMPNESS
AND MOULD from 2009 produced by the
WHO.
Living in residences with high humidity
levels increases the risks of illnesses.
The table summarises the symptoms in
percentages that occur to people living in
environments with polluted air.
Symptom Percentage increase in symptoms
Upper respiratory related symptoms 52%
Cough 50%
Hoarseness 44%
Asthma already diagnosed 50%
Asthma not diagnosed 33%
Development of asthma 30%
People who live in “unhealthy” buildings
can be subject to asthma and allergies; the
risk of contracting rare diseases line chron-
ic rhinitis, allergic alveolitis, or hypersensi-
tivity pneumonitis are increased.
Internal environmental pollution has con-
sequences, not only on health, but also
on society. All the diseases shown here
constitute a significant cost for the health
system. The Italian Ministry of Health pro-
duced in 1999 a study on the impact these
pollutants have on the population and the
direct health costs.
Bad air quality certainly has effect on
human productivity, both at work and
school. We all have experiences of reduced
concentration in closed environments
without ventilation.

IREPPY - 1404 - 4238051_01
4.2. PLASMACLUSTER
Each RePuro unit is supplied as standard
with a Plasmacluster filter.
Plasmacluster is a system of ion genera-
tion suitable for the purification of internal
spaces. It works by deactivating bacteria
and viruses present in the air.
It is not an electrostatic filter, having an air
purification mechanism. Using a genera-
tor it decomposes certain water molecules
present in the air (humidity) by electrical
discharges, creating a flow of hydrogen and
oxygen ions.
Molecules or atoms electrically charged
are called ions. The process of electron
gain or loss is called ionisation. Ionisation
is normally carried out by the application
of high energy to the atoms, in the form of
electrical potential or radiation. . An ion-
ised gas is called “plasma”.
The positive and negative ions thus gener-
ated are supplied to the space, transport-
ed by the treated air flow, and attract the
water molecules present creating “clus-
ters” of molecules.
As the process continuous these clusters
collect around a pollutant agent (for ex-
ample, a virus). At this point positive and
negative ions unite to form the hydroxyl
radical OH- which removes the hydrogen
from the surrounded virus, necessary for
its survival.
From the hydroxyl OH-acquiring the hy-
drogen, water is produced which is intro-
duced to the space; the virus is damaged
by the reaction and therefore eradicated.
The Plasmacluster purification process is
completed.

12 IREPPY - 1404 - 4238051_01
Compared to electrostatic filter the Plas-
macluster technology has four main ad-
vantages:
• In electrostatic filters the air is forced
through a metallic filter where the elec-
trostatic precipitation is produced. The
polluting particles are violently attracted
to the metal plates that make up the filter
by strong electric fields, where they then
remain energetically attached. All the pol-
lutants thus captured remain strongly at-
tached to the filter plates, and with the
use of the de-purifier, get progressively
dirtier until a visible layer of inert material
forms over time. At this point the dirt is re-
moved from the filter.
• The filter becomes a pressure drop as
it visibly gets dirty during operation, and
requires periodic cleaning as required by
its appearance. From this it can be easily
understood that over time there is a pro-
gressive degradation in filter efficiency of
such devices.
• Another important advantage is in the
electrical voltage which is around 10-12kV
for electrostatic filters, whilst for the Plas-
macluster system it is 100-200V. Some
electrostatic filters must have regulation
systems to stabilise the high voltages and
short circuit protection systems on the
high voltage of the filter itself.
• Traditional electrostatic filters, unlike the
Plasmacluster system, only operate well in
constant operating conditions, are physi-
cally large, normally require a pre-filter to
avoid overloading the filter and frequent
maintenance.
Plasmacluster works mainly on four fronts,
described here.
The following show the results on several viruses which are sadly well known.

To see the action of Plasmacluster on vi-
ruses here are two electron microscope
images. The left shows the virus (Feline
coronavirus) before exposure and the
right the same virus inactivated from the
action of the ioniser.
Inactivation of viruses
As described above, the ions freed by
Plasmacluster adhere to the surfaces of
microbes removing hydrogen from the pro-
tein that they are made from: this process
makes them inactive.
Numerous studies carried out by prestig-
ious European and Japanese universities
have been conducted on this matter.

Mould
As with viruses and bacteria, the ions
freed by Plasmacluster work on the pro-
liferation of the mould in closed spaces. .
A test conducted by Japanese researchers
has shown how the exposure of a normal
PVC window to the action of the Plasma-
cluster filter has allowed the reduction,
compared to a similar unit, of around 25%
of the mould that was created over a pe-
riod of 5 days.
This also has a positive effect on the mould
carried in suspension in the air. According
to a test carried out by the Ishikawa Health
Service Association, the Plasmacluster op-
erating in a room of 13m2has drastically
reduced the content in the period of about
three hours.
Elimination of odours
It has been shown that the use of Plas-
macluster facilitates the elimination of
odours created in spaces.
A test was made analysing a sample cloth
infused with cigarette smoke. In normal
conditions the odour drops to impercep-
tible levels in 4 hours, but with the use of
Plasmacluster this time is reduced to one
hour.
Development of allergens
Several studies have shown how the ion-
iser has inhibited the protein of which the
allergens are made up from, generated
from dust mites faeces, dead dust mites,
which are one of the main sources of al-
lergies.
Plasmacluster works both by inhibiting
any mites present and on their prolifera-
tion.
Germicidal lamp
RePuro can be combined with accessories
from the plenum series PLS and PLSM;
these accessories can be supplied with the
germicidal lamp which integrates the ac-
tion of the Plasmacluster for a better pu-
rity of air supplied to the room.
This exclusive device with germicidal lamp
with mercury vapour sterilises the air with
a microbiological effectiveness of 99.999%
inactivating all microorganisms Gram - and
Gram + .
The germicidal lamp is located in the supply
air to ensure a higher cleaning of the duct-
ing, preventing the formation of mould and
ensuring the maximum level of efficiency
and reduction of cleaning requirements.
Such a device for the sterilisation of air
makes RePuro indispensable in rooms that
require the maximum level of hygiene such
as hospitals, dental studios, medical and/
or veterinary surgeries, analysis laborato-
ries, pharmaceutical laboratories, waiting
rooms, beauty centres, residences, offices,
and public places.

4.3. REFERENCE STANDARD FOR THE
VENTILATION OF RESIDENTIAL BUILD
INGS
The concept of air ventilation for confine
spaces is taken into consideration by sev-
eral standards.
The Standard EN 12792:2003 (Ventilation
for buildings – symbols terminology and
graphical symbols) defines two concepts:
Aeration: meaning natural ventilation by
opening a window.
Ventilation: meaning the extraction and sup-
ply of air to a space. It is interesting to note
that the standard talks about “designing” for
ventilation.
The   talks about the
energy efficiency of buildings and defines
it as the quantity of energy effectively con-
sumed or that is anticipated to be required
to satisfy the various needs connected to
the standard use of a building, including
amongst others: heating of water, cool-
ing, ventilation and lighting. The directive
underlines to take account of the general
climatic conditions of the internal spaces in
order to avoid any negative effects due to
inadequate ventilation.
Note that it talks about ventilation and not
aeration, and even the standards that deal
with the renewal of air always use the term
renewal and not aeration: opening and
closing windows is not considered an effec-
tive system for the renewal of air.
How and when to renew is considered in
EN 15251:2007 (Criteria for the indoor envi-
ronment including thermal, indoor air quality,
light and noise), which combines aspects of air
quality within buildings with energy aspects.
Having said that the air quality in buildings
depend on numerous parameters (number of
people, activities carried out, humidity, smoke,
emissions from furniture and construction ma-
terials, etc.), it is an essential fact that ventila-
tion must be continuous, and acceptable that
the air renewal rate requirement is variable
depending on whether the space is occupied
or not.
If not occupied the air renewal rate is be-
tween 0.05 and 0.1l/s, per m2.
If the space is occupied the same stand-
ard defines different air renewal classes:
the higher the renewal rate the higher the
building class.
I: High requirement level, recommended
for spaces occupied by very sensitive and
fragile people with special needs, such as
the handicapped, the sick, very small chil-
dren and the elderly.
II: Normal requirement level, to be used for
new constructions and renovations.
III: Acceptable, moderate requirement lev-
el, to be sued for existing buildings.
IV: Values outside of the criteria for the cat-
egories above. This category might only be
accepted for a limited part of the year.
(a): The air renewal ratel expressed in l/s per m2and Vol/h (hourly volume) coincide with a ceiling height of 2.5 m.
(b): The number of occupants of a dwelling can be evaluated from the number of bedrooms.
If there are any national or local requirements these are used.

Suppose we have to design an air renewal
system for an apartment of S=100m2with
room heights of h = 2.5m.
As recommended by the standard EN
15251:2007, if we want to ensure a catego-
ry III, the air renewal rate must be:
S × h × 0.5 = 100 × 2.5 × 0.5 = 125m3/h
if the space is occupied. But if the space is
not occupied the air renewal rate becomes:
S × 0.05 = 100 × 0.1 = 10l/s = 36m3/h

4.4. EXAMPLE OF ENERGY SAVING
CALCULATION
The following shows an analysis made on
the energy advantage for the heat recov-
ery solution used in a residential building
located in 2468 DD climatic zone (EN ISO
15927-6:2007).
The analysis takes into consideration a por-
tion of a twin apartment, with useful sur-
face area of 150m2. The dwelling consists of
two stacked floors.
The chart shows the winter primary ener-
gy use (EPi) expressed in kWh/(m2x year)
of the same building.
In the three cases the EPi value of the en-
closure is equal at 37,578 kWh/(m2per
year), whilst the dierence in the columns
is due to the air renewal variaon in re-
newal rate and how it is achieved.

With renewal rate 0.5Vol/h

In the absence of controlled mechanical
venlaon the air ow renewal rate of
spaces is xed at 0.3Vol/h: in such a case
the EPi index of the building is esmated as
55,978kWh/(m2per year).
Such air renewal is not sucient to have
a good space air quality which must be at
least 0.5vol/h according to EN 15251. Such
a renewal rate can be obtained with a me-
chanical venlaon system with eciency
of 50%: in which case the EPi becomes
52,928 kWh/(m2per year).
If instead a high eciency mechanical ven-
laon system like RePuro is used, this re-
quirement becomes 40,522kWh/(m2 per
year).
In the rst case (aeraon) of the building is
in class B for energy performance for win-
ter condioning and the air quality is low.
In the last case with high eciency heat re-
covery not only is the minimum air renewal
in accordance with standard EN 15251, but
the building increases its energy perfor-
mance for winter condioning.
For the soluon with mechanical venla-
on (CMV) with 50% eciency the EPi
increases considerably with increasing air
renewal rates, but with the RePuro solu-
on the value also increases, but consider-
ably less.

4.5. HEAT RECOVERY ENERGY EFFI
CIENCY
Generally heat exchanger energy ef-
ciency is dened as the relaonship
between actual energy exchanged be-
tween the two air masses (extract air
and supply air) and the ideal energy:
η = Qreal
Qideal
If the air flow rates are equal (supply and
extract), the efficiency becomes the ratio
between temperature difference:
η = Qreal
Qideal
η = tsupply air - texternal air
tinternal air - texternal air
For example, if:
texternal air = -5°C
tinternal air = 20°C
The supply air temperature is determined
once the efficiency of the heat recovery
unit is known.
Then:
tsupply air =
= η × (tinternal air - texternal air) + texternal air
So if η = 0.9 with the values shown you
have:
t supply air = 0,9 × (20+5)-5 = 17.5°C
The directive is split into two steps: the
first in 2013 and a more restrictive one in
2015.
In RePuro, not only do the fans greater
than 125W already respect the 2015 lim-
its, but even those of lower capacity do.
Certification ErP 2015
ErP
2015
With the implementation of the Kyoto
Protocol the European Union has fixed an
objective to reduce by 20% energy con-
sumptions, by 20% CO2emission and to in-
crease by 20% the renewal energy sources
by 2020.
These measures, known as 20-20-20 also
involves the ventilation industry.
The Product Directive 2009 (known as ErP
2015, Energy related Products Directive),
has established that for all types of fans,
with capacities between 0.125kW and
500kW, which operate as “stand alone” or
as components within a system, must have
a minimum efficiency depending on the
type of fan and its capacity. This efficiency
is not given only to the motor but for the
assembly of motor + controller (for exam-
ple, inverter) + Fan.
