Ao fazer pesquisas sobre HVAC, voc\u00ea ouvir\u00e1 muitos termos como FCU, AHU, PAU, RCU, MAU, FU, HRV, FAU, OAC, EAF, <\/strong>etc. Para ser honesto, pode ser muito confuso para algu\u00e9m que n\u00e3o conhece a ind\u00fastria de HVAC. Neste artigo, aprenderemos sobre os termos HVAC mais comuns que s\u00e3o frequentemente usados para sistemas e subsistemas HVAC.<\/p>\n\n\n\n

<\/a>O que \u00e9 FCU (Unidade Fan Coil)<\/h2>\n\n\n\n

Uma unidade Fan Coil, ou FCU na ind\u00fastria de HVAC, usa um ventilador e uma bobina para aquecer ou resfriar a sala. Este sistema n\u00e3o requer uma conex\u00e3o Ductwork. As FCUs s\u00e3o frequentemente usadas em trabalhos em edif\u00edcios residenciais, industriais ou comerciais. \u00c9 o sistema mais comum na ind\u00fastria HVAC. O ventilador move o ar para a bobina, onde o ar fica frio ou quente antes de empurrar o ar de volta para a sala. A instala\u00e7\u00e3o do FCU \u00e9 mais barata do que um sistema HVAC de duto. As FCUs est\u00e3o dispon\u00edveis em diferentes tipos de montagens, como teto, piso e independentes.<\/p>\n\n\n\n

\"Unidade<\/figure>\n\n\n\n

<\/a>O que \u00e9 AHU (unidades de tratamento de ar)<\/h2>\n\n\n\n

Uma unidade de tratamento de ar ou AHU \u00e9 um dispositivo usado para sistemas HVAC. AHU \u00e9 um enorme dispositivo de ar condicionado interno com caixa de metal que geralmente \u00e9 instalado no telhado. Ele usa ar externo e interno para ar condicionado. A AHU coleta o ar pelos ventiladores e remove impurezas como poeira e outras part\u00edculas e, em seguida, fornece ar refrescante aos ambientes atrav\u00e9s dos dutos. O sistema AHU tamb\u00e9m utiliza uma serpentina cheia de \u00e1gua ou refrigerante, para resfriar o ar. O ar coletado passa por uma s\u00e9rie de filtros de ar antes de chegar \u00e0 serpentina e ser enviado de volta aos dutos com o aux\u00edlio de ventiladores.<\/p>\n\n\n\n

<\/a>O que \u00e9 RCU (Unidade de Tratamento de Ar Reciclado)<\/h2>\n\n\n\n

A unidade de tratamento de ar reciclado ou RCU \u00e9 uma unidade de circula\u00e7\u00e3o de ar interna que controla a circula\u00e7\u00e3o de ar em HVAC. O objetivo do RCU \u00e9 manter a press\u00e3o interna, a temperatura e o n\u00edvel de umidade.<\/p>\n\n\n\n

<\/a>O que \u00e9 DCC (bobina de resfriamento a seco)<\/h2>\n\n\n\n

A serpentina de resfriamento a seco ou DCC \u00e9 usada em um sistema de resfriamento interno, onde as serpentinas s\u00e3o resfriadas por \u00e1gua gelada. A principal fun\u00e7\u00e3o da serpentina de resfriamento a seco \u00e9 eliminar o calor sens\u00edvel do ambiente. Este calor sens\u00edvel \u00e9 produzido por pessoas, m\u00e1quinas ou raios.<\/p>\n\n\n\n

<\/a>O que \u00e9 MAU (unidade de maquiagem-AIr)<\/h2>\n\n\n\n

A unidade de ar complementar ou MAU tamb\u00e9m \u00e9 um tipo de sistema HVAC. O ar de reposi\u00e7\u00e3o foi projetado para edif\u00edcios e espa\u00e7os que necessitam de alta qualidade do ar interno (IAQ). Em alguns edif\u00edcios, o ar n\u00e3o pode ser recirculado. Esses espa\u00e7os podem ser perigosos para a sa\u00fade, por isso a MAU foi projetada para fornecer ar fresco externo a esses espa\u00e7os. A MAU extrai ar fresco do exterior para substitu\u00ed-lo pelo ar existente no interior do edif\u00edcio. MAU \u00e9 um grande manipulador que fornece ar fresco condicionado aos espa\u00e7os e tamb\u00e9m produz ar quente e frio. Uma unidade de ar complementar \u00e9 uma solu\u00e7\u00e3o onde a ventila\u00e7\u00e3o do ar \u00e9 altamente necess\u00e1ria devido ao menor fluxo de exaust\u00e3o.<\/p>\n\n\n\n

<\/a>O que \u00e9 filtro HEPA de alta efici\u00eancia<\/h2>\n\n\n\n

HEPA ou (filtro de part\u00edculas de alta efici\u00eancia) \u00e9 um filtro de ar plissado mec\u00e2nico usado na ind\u00fastria de HVAC. Os filtros HEPA t\u00eam uma efici\u00eancia de filtragem de ar de 99.97%. Ele pode remover part\u00edculas de ar, como poeira, bact\u00e9rias, p\u00f3len, mofo e qualquer outra part\u00edcula com tamanho de 0,3 m\u00edcrons (\u00b5m).<\/strong><\/p>\n\n\n\n

O principal objetivo dos filtros HEPA \u00e9 fornecer ar puro de alta qualidade sem contaminantes. O ar pode passar por esses filtros, mas as part\u00edculas de ar com tamanho de 0,3 m\u00edcron ou superior n\u00e3o podem passar. Em filtros de ar, a filtragem de 0,3 m\u00edcron \u00e9 considerada altamente eficiente, uma vez que a maioria das part\u00edculas de ar s\u00e3o maiores em tamanho; a filtragem de 0,3 m\u00edcron \u00e9 uma tranquilidade. Os filtros HEPA s\u00e3o usados em salas de cirurgia, laborat\u00f3rios e locais altamente limpos onde a qualidade do ar \u00e9 altamente preocupante.<\/p>\n\n\n\n

<\/a>O que \u00e9 PAU (unidade de pr\u00e9-resfriamento de ar)<\/h1>\n\n\n\n

PAU significa unidade de pr\u00e9-resfriamento de ar em HVAC. O dispositivo PAU \u00e9 uma unidade grande que coleta o ar externo com alta umidade e o envia para a AHU (unidade de tratamento de ar). A PAU (Unidade de Ar de Pr\u00e9-resfriamento) tamb\u00e9m funciona como desumidificador e controla o n\u00edvel de umidade desejado no ar do edif\u00edcio.<\/p>\n\n\n\n

\"Unidade<\/figure>\n\n\n\n

<\/a>O que \u00e9 EAF (ventilador de exaust\u00e3o)<\/h2>\n\n\n\n

Ventiladores de exaust\u00e3o ou EAFs s\u00e3o usados para remover o ar do espa\u00e7o. O EAF remove o odor e a umidade do espa\u00e7o e abre espa\u00e7o para um novo ar condicionado fresco. EFA (ventiladores de exaust\u00e3o) s\u00e3o usados principalmente em \u00e1reas congestionadas onde a ventila\u00e7\u00e3o do ar \u00e9 necess\u00e1ria.<\/p>\n\n\n\n

<\/a>O que \u00e9 OAC (unidade de controle de ar externo)<\/h2>\n\n\n\n

A unidade OAC \u00e9 um subsistema do sistema HVAC. A unidade OAC \u00e9 utilizada em espa\u00e7os fechados para fornecer ar fresco. O OAC pode controlar a umidade, o fluxo de ar, a temperatura e a press\u00e3o do ar de ventila\u00e7\u00e3o.<\/p>\n\n\n\n

FFU (unidade de filtro de ventilador)<\/p>\n\n\n\n

FFU ou unidade de filtro de ventilador \u00e9 um dispositivo que fornece ar puro de alta qualidade. \u00c9 usado principalmente para fornecer ar purificado a laborat\u00f3rios, instala\u00e7\u00f5es m\u00e9dicas, salas de aula e espa\u00e7os onde a qualidade do ar \u00e9 altamente preocupante. A FFU (unidade de filtro de ventilador) possui seu pr\u00f3prio ventilador motorizado e um filtro HEPA que purifica o ar. O FFU coleta o ar da parte superior e o filtra atrav\u00e9s do filtro HEPA e depois fornece na velocidade de 0,45 m\/s \u00b1 20%.<\/strong><\/p>\n\n\n\n

<\/a>O que \u00e9 HRV (ventila\u00e7\u00e3o de recupera\u00e7\u00e3o de calor)<\/h2>\n\n\n\n

HRV (ventila\u00e7\u00e3o de recupera\u00e7\u00e3o de calor) tamb\u00e9m \u00e9 conhecido como ventilador de recupera\u00e7\u00e3o de calor ou trocador de calor total. Como o nome indica, HRV \u00e9 um sistema de ventila\u00e7\u00e3o de ar que troca o ar interno com ar externo fresco. O HRV \u00e9 adequado para ambientes frios onde o n\u00edvel de umidade \u00e9 maior. Durante a esta\u00e7\u00e3o de aquecimento, o HRV recolhe o calor do ar exterior e utiliza a energia t\u00e9rmica para pr\u00e9-aquecer. Esta fun\u00e7\u00e3o \u00e9 muito adequada na esta\u00e7\u00e3o de aquecimento devido \u00e0 energia externa que recolhe, tornando-a muito eficiente em termos energ\u00e9ticos. Na esta\u00e7\u00e3o de resfriamento, o HRV retira o calor do ar que entra e retira a carga do ar condicionado. O HRV pode ser usado em conjunto com o sistema VRV.<\/p>\n\n\n\n
