Os Desafios de um Hospital Atual
Museu da Imprensa - Madeira
História, percurso empresarial VieiraLopes, o Alvaro Vieira e o
Marco Lopes, começaram como instaladores de Ar condicionado e
sistemas de ventilação em 1998, logo após 5 anos de actividade,
começou-se a perceber que existia uma grave crise no setor da
construção civil.
Nessa altura, o outro socio gerente Alvaro Vieira por cautela,
começou com a ideia de se reformar, também com receio em
relação à evolução dos acontecimentos no ramo da construção
civil. Esta situação fez com que Marco Lopes adquirisse a sua cota
na empresa VieiraLopes.
Claro, era factual que a única forma de alterar a crescente divida
de clientes, problemas de cobrança, prazos de recebimento muito
alongados, favorável enquadramento jurídico para as grandes
construtoras em detrimento das PME’s…era mudar a estratégia, o
percurso da empresa.
Quem somos?
Agradecimentos Associação Portuguesa de Infeção Hospitalar (APIH) e a
Associação de Técnicos de Engenharia Hospitalar
Portugueses (ATEHP), Secretaria Regional da Saúde da
Região Autónoma da Madeira, Museu da Imprensa, Câmara
de Lobos.
Apostou-se em dois caminhos distintos: 1. A criação de uma atividade paralela industrial/fabrico e mudança geográfica na atividade da VieiraLopes.
Apostamos no mercado Espanhol inicialmente e depois no Francês onde estamos à cerca de 7 anos, mais recentemente com uma empresa local VLopes Clim na zona de Paris. Faturamos cerca de 5M€. Iniciamos à cerca de 2 anos em Copenhaga VLopes Scandinavia.
Por outro lado a OCRAMclima começou a operar como um fabricante de Unidades de Tratamento de Ar (UTAs) à cerca de 7 anos também possuindo a Unidade Industrial em Braga.
Claro, no caso da Ocram, temos a sorte de ter uma longa experiência e know-how para operar de forma eficiente e centrada na resolução de problemas, pois nascemos como instaladores. O "core business" de OCRAMclima é o fabricante e comercialização de unidades de tratamento de ar e produtos associados.
Temos agora uma vasta gama de equipamentos, unidades de ventilação, unidades de baixo perfil, Chillers, bombas de calor e sistemas de purificação de ar. Trabalhamos em conjunto com os nossos clientes para responder melhor às suas necessidades e oferecer as melhores soluções. A qualidade do ar interior é uma das principais preocupações internacionais. Afim de resolver os requisitos legais e ajudar a melhorar a qualidade do ar interior, oferecemos uma ampla gama de purificação NPS ® sistemas para operar individualmente ou integrar nossos produtos.
Na aposta Ocram Clima foi seguido um trajeto com uma forte componente I&D.
A chave para o sucesso desta nova atividade centrou-se nas seguintes apostas:
Análise profunda dos Decretos-Lei da atividade e das alterações futuras das diretivas comunitárias centradas certificação energética de edifícios e da qualidade do ar interior;
Certificação ISO 9001 do Departamento Industrial;

A pergunta que se põe é a seguinte:
Qual é mais importante, questões de saúde humana (QAI) ou eficiência energética dos
edifícios? O legislador Português para já escolheu a eficiência energética… Agora
felizmente esta legislação permite que saiam portarias com intuito de criar um
sistema de fiscalização, ou seja, a porta está aberta para a melhoraria…
Em todo este contexto analisamos muito bem a referida norma ASHRAE 62.1. A maioria
das alterações legislativas baseou-se nesta norma e percebemos que ela aborda um
tema realmente interessante, a relação entre eficiência energética e QAI, sendo
que a existência de sistemas dinâmicos de purificação de ar, já previstos nesta, são
a chave para a resolução da maior parte dos problemas. Recordo que é muito mais
complicado dimensionar um sistema de climatização num edifício de grande altura
(vertical) do que em construção horizontal mais típica nas cidades europeias. O
espaço necessário para as condutas do ar, as necessidades de ar fresco exterior
devido aos envidraçados fechados, a própria contaminação exterior em grandes
cidades, jogam a favor destas tecnologias. Daí que os EUA estão mais empenhados
devido à natureza tecnológica e estado da arte dos sistemas de purificação de ar na
sua economia, isto é, em seguir um caminho de utilização de sistemas de
purificação de ar dinâmicos. Aliás a certificação de edifícios verdes ASHRAE prevê
uma bonificação significativa aquando da utilização deste tipo de sistemas.
NPS ®
O sistema de purificação de ar tem como objetivos:
No mínimo, reduzir os poluentes concentrações aos limites legalmente
exigidos
Desnaturar e / ou destruir os microrganismos (bactérias, fungos )
Decompor compostos orgânicos voláteis em espécies não agressivos
Fazer isso com baixa perda de pressão para uma melhor eficiência energética
Radiação
UVGI
Superfície
fotocatalítica
Um sistema de purificação de ar dinâmico é uma espécie de catalisador, como vulgarmente vemos nos automóveis interagindo com os elementos nocivos do ar, à sua passagem e através de reacções físico-químicas alterando as suas características com o intuito de no final termos um ar mais “puro” ou seja descontaminado. No caso de vírus, bactérias, fungos inativando a sua actividade, por quebra nas ligações proteicas do DNA, no caso de COV’s ou Formaldeído, por ionização catalítica do ar e posterior oxidação destes elementos adsorvidos nas superfícies catalíticas. A diferença para os sistemas tradicionais, existentes na generalidade dos equipamentos de ar condicionado é que a filtragem é apenas estática, como uma rede que retém à passagem as partículas que arrastam estes elementos.
Nós inventamos o NPS (Nano Purifying System) onde conseguimos estes efeitos e “gastamos” assim, quando instalado num sistema, Unidade de Tratamento de Ar (UTA), menos ar exterior, utilizado mais recirculação do interior. Regula-se a inserção de ar fresco exterior apenas pela quantidade de pessoas e respectivo consumo de CO2. Coloca-se sondas de qualidade de ar e tudo é analisado como se trata-se, utilizando uma analogia, de regular a temperatura ambiente.
À alguns anos a regulação da temperatura começou a ser uma obrigatoriedade no inverno, passando depois a ser também no verão. Nos dias de hoje em locais mais exigentes existe também a regulação da humidade. Portanto a busca do conforto humano é uma evolução constante. No futuro a QAI será certamente uma realidade/obrigatoriedade não para efeitos de conforto mas sim de saúde humana isso não temos dúvidas!
Cabe a todos contribuir para que as coisas mudem…
First, what is Cleanroom?
“A room in which the concentration of airborne particles is controlled, and
which is constructed and used in a manner to minimize the introduction,
generation, and retention of particles inside the room and in which other
relevant parameters, e.g. temperature, humidity, and pressure, are
controlled as necessary.”
From ISO 14644-1
“A room in which the concentration of airborne particles is controlled and
which contains one or more clean zones.”
From Federal Standard 209E
Contamination Monitoring and Control Systems
Just some curiosities...
Although the cleanrooms of yesteryear had similarities to modern cleanrooms,
a principal omission was positive ventilation by filtered air. The use of
ventilation, albeit the natural type, to reduce bacterial infection had been
advocated by people such as Florence Nightingale and mechanical ventilation
was provided in the hospital designed for the Crimea by Brunel in 1855.
However artificial ventilation was rare until about 60 years ago.
Contamination Monitoring and Control Systems
Ventilation of hospital room in the 1920s
A patient could inhale
fresh air from the
funnel. Foul air from
the floor was
extracted by another
funnel.
Contamination Monitoring and Control Systems
The development of contamination
control and cleanrooms
Primarily been a result of research and development taking place from 1940 onwards. Some of these development and research projects are as follows:
• The atomic bomb (the Manhattan project) - 1942-1944;
• The biological and chemical war industry;
• Instrumentation for the air and space industry;
• Industries working with miniaturization;
• Industrial plants dealing with radioactivity or hazardous microorganisms;
• The space program;
• Surgical operations;
• Tumour therapy, both when producing, preparing and administering solutions containing cytostatic components;
• Microelectronics.

Contamination Monitoring and Control Systems
Unidirectional flow type cleanroom
The air changes are normally equal to, or greater than, 20 per hour, this being much greater than that used in ordinary rooms, such as in offices. In this style of cleanroom, the contamination generated by people and machinery is mixed and diluted with the supply air and then removed.
This air sweeps across the room in a unidirectional way at a speed of around 0.4 m/s and exits through the floor, thus removing the airborne contamination from the room. This system uses much more air than the turbulently ventilated cleanroom but, because of the directed air movement, it minimizes the spread of contamination about the room and sweeps it out through the floor. Contamination Monitoring and Control Systems
The dispersion and spread of
contaminants
Different contaminants will have different impacts on production processes and products. It is therefore of major importance to be fully cognizant of all aspects of the production process and of how to control them.
The following list contains some of the major sources of contamination that pose a risk to the production process:
- Personnel
- Incoming ventilation air
- Machinery and other equipment for production
- Raw material and semi-finished material
- Packaging material
- Different media used in the production process as well as chemicals used for cleaning

Contamination Monitoring and Control Systems
So, lets add something more.
Photocatalysis is the acceleration of a photoreaction in the
presence of a catalyst. In catalysed photolysis, light is
absorbed by an adsorbed substrate.
In photogenerated catalysis, the photocatalytic activity (PCA)
depends on the ability of the catalyst to create electron–hole
pairs, which generate free radicals able to undergo secondary
reactions.
Contamination Monitoring and Control Systems
How does Photocatalysis work
UV irradiation (photon) with energy equal to or
greater than TiO2 band-gap.
Promote the passage of
electrons from VB to CB,
generate an electron-hole
pair. Electron-hole pair
have enough lifetime
to migrate until
reach catalytic
surface and
participate in RedOx
reactions.
Contamination Monitoring and Control Systems
How does Photocatalysis work
Electron react with oxygen and
generate superoxide radical anion
(O2-).
Hole react with water to produce
hydroxyl radical (•OH).
Superoxide radical anion (O2-) and
hydroxyl radical (•OH) are highly
reactive and they can oxide VOC’s.

UVGI Photocatalysis
Contamination Monitoring and Control Systems
Why UV - UVGI
UV is an electromagnetic radiation with
a wavelength shorter than that of visible light, but
longer than X-rays, that is, in the range between 400 nm
and 10 nm, corresponding to photon energies from
3 eV to 124 eV
UVGI – Ultraviolet germicidal irradiation
An already well know and documented technology, but
still one very effective if used properly.
This a specific region of UV that has germicidal
properties.
Contamination Monitoring and Control Systems
The UVGI disinfection
UVGI ultraviolet radiation in the range of UVB and UVC (ultraviolet radiation-
region B and C with wavelength of 280-320 nm and 200-280 nm, respectively),
causes photochemical reactions with DNA and RNA, with absorption peak of UV
by the nucleic acids in the range of 260-265 nm Contamination Monitoring and Control Systems
The UVGI disinfection
The photochemical
reaction causes thymine
dimerization in the nucleic
acids and it is
consequently carrying to
the inactivation or
destruction of the
microorganism, in case of
sufficient damages caused
in the genetic material. The production of thymine dimers caused
by UV exposure has been, repeatedly,
demonstrated with effective inactivation
of bacteria and DNA virus.
Contamination Monitoring and Control Systems
Because Biology is more complex than
what it seems… For the success of errors introduction in microorganisms’ genetic
sequences, in case of thymine dimers, this bases should be correctly
positioned during the instant of light absorption, in which the
formation of thymine dimers corresponds to a window of 1 × 1,012 s
after the beginning of excitement with UV radiation.
Only a few percent of the
thymine doublets are likely to
be favorably positioned for
reaction and dimerization at
the time of UV excitation.
Dimerization process for a thymine
doublet with the appropriate
orientation.
Contamination Monitoring and Control Systems
Challenge – how to transfer the
phenomena to a system?
UV needs time to create sufficient errors in the genetic structures of
microbes
VOCs pollutants have to contact with catalytic
surfaces to suffer photocatalytic degradation.
?
Contamination Monitoring and Control Systems
A 4th filtration stage
Maybe an utopia but we aim to deliver an air
purification system capable of denature and/or
destroy microbes and decompose Volatile
Organic Compounds (VOCs). Contamination Monitoring and Control Systems
What for?
The air purification system aims to:
- As a minimum, reduce pollutants concentrations to the legally required limits
- Denature and/or destroy microorganisms (Bacteria, Fungi)
- Decompose VOCs into non-aggressive species
- Do this is with low pressure drop to better energy efficiency
Contamination Monitoring and Control Systems
How we did it
The TiO2 surfaces were coated by sputtering allowing a perfect physical deposition of the semiconductor in the catalytic surfaces of the air purification system.
SPUTTERING - is a process
whereby atoms are ejected fro
m a solid target material due
to bombardment of the target
by energetic particles.
Contamination Monitoring and Control Systems
Air sprayed nanoparticle deposition
TiO2 Nanoparticles deposition.
HVLP (High Volume Low
Pressure)
Was used to achieve higher
volume (HV) of air to
aerosolise and propel the
coating solution at lower
pressure. The result is a
higher proportion of paint
reaching the target surface
with reduced overspray,
materials consumption, and
air pollution.
A special spray nozzle and pressures
were used to achieve the best
possible nanoparticles’ deposition.
This method is very helpful when we
are coating large surfaces that by
sputtering would not be possible to
do.

Because of large difference in

concern. At the first system for AHU
we used UV LEDs, just for testes.

LU45 - Airborne Pathogen Detection System
Low Cost Contamination Detection Implementing the LU45 can not only have significant impacts on the effective management of airborne pathogens it can also result in lowering the overall cost of airborne contamination detection and remedial action.
The LU45 is designed to be fully automated requiring no
specialist training to operate. One operative can manage a large number of installed units with human intervention required only when a contamination event has been detected and a cartridge needs to be changed.
The LU45 also eliminates the need for external laboratory
analysis which can be expensive as the cloud based software performs automated analysis and reporting when a contamination event is detected.
•Less intervention – only requires intervention to change
cartridges
•Low cost solution resulting in the reduction of overall
contamination
risks and expenses. •Low cost wireless installation

• NPS, with the help of Microbiologic Sensors
Rapid microbial detection sensors that operates in conjunction with control platform. It facilitates remote monitoring of airborne pathogens (bacteria,
yeasts & moulds) and revolutionizes the approach to pathogen detection and control by significantly shortening contamination detection times and
automating the monitoring and detection process.
Real-time detection and reporting of air contamination events helping prevent or control an outbreak of airborne contaminants e.g. listeria in
your food production plant or E.coli in your healthcare facility. Sensors has been engineered to periodically draw a sample of ambient air into the
device where it performs optical density measurements on growth facilitation media to determine if microbial contamination is present.
