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;

Certificação dos produtos na TÜV (Alemanha) e EUROVENT;

Potenciou-se fortemente a Relação com a Universidade do Minho (UM) Tecminho;

Participação em projeto IDI do 7º Programa-Quadro de apoio comunitário;

Laboratório de Investigação instalado na Universidade do Minho com contrato de exploração através de um QREN;

Participação em inúmeros eventos internacionais na área de purificação de ar, quer como especialistas quer como interessados no conhecimento;

Candidatura, tendo ganho o Concurso Nacional de Inovação na área de Clean Tech e Processos Industriais 2012, tendo por base o conhecimento adquirido;

Quatro “model box” certificada na TÜV (Alemanha) e EUROVENT elevado nível de exigência de qualidade, graus D1(resistência mecânica)/L1(estanquicidade)/T2TB2(Térmica), ou seja grande investimento no desenvolvimento do produto;

Clientes que confiam em nós

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.


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.


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.

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

Phenomena

UVGI Photocatalysis


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.


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.


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.

Air Purification

Phenomena

UVGI Photocatalysis


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.


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.


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.


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.

?


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


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.


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.

processes for microbes and

Because of large difference in

scale, energy efficiency was a

concern. At the first system for AHU

we used UV LEDs, just for testes.

Although this technology is still far

from industrial use, mainly because

of life time. Contamination Monitoring and Control Systems

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

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.
