8 m³ Controlled Climate Test Room

Walk-In Temperature and Humidity Testing for Large Assemblies and Batch Loads

The DERUI 8 m³ walk-in temperature humidity test chamber provides a configurable conditioned room for full-size assemblies, equipment racks and multiple products. Airflow, refrigeration, heating and humidification are engineered around the actual load and test profile rather than volume alone.

Application Fit

What Fits an 8 m³ Walk-In Climate Chamber?

Nominal volume is not the same as usable test space. Air supply and return, wall clearance, floor loading, door swing, cable routing and service access reduce the usable envelope.

Automotive and Electronics

Condition control cabinets, vehicle electronics, charging equipment, instrument assemblies and component batches.

Energy and Industrial Systems

Test power electronics, energy-storage subsystems, enclosures and industrial products when the approved safety configuration supports them.

Materials and Packaged Products

Run temperature-humidity conditioning, storage and durability profiles on large parts or multiple packaged specimens.

Capacity check: provide the specimen drawing, quantity, mass, heat dissipation, rack dimensions and clearance. DERUI should confirm usable workspace and airflow before quotation.
Climate Control

How the Chamber Maintains Temperature and Humidity

Forced-Air Recirculation

An externally driven extended-shaft centrifugal fan circulates conditioned air. Supply and return geometry should limit dead zones and avoid direct airflow that biases specimen temperature.

Refrigerant Clarification

Confirm the Final Refrigeration Architecture

The source first lists R404A and later R404A/R23. This may represent single-stage and cascade options, but it is not one confirmed specification. Zero ozone-depletion potential does not by itself make a refrigerant low-impact; review local rules, service availability and global-warming potential.

Confirm compressor brand, stages, refrigerant(s), charge, condenser type and any alternative refrigerant before publication.
Perguntas Frequentes

8 m³ Walk-In Temperature Humidity Chamber FAQs

What does 8 m³ mean?

It is nominal internal volume. Exact dimensions vary, and usable volume is smaller after airflow, rack and access clearances.

What temperature and RH range does it provide?

The source does not include approved ranges. DERUI should issue the temperature range, RH range and operating chart for the selected configuration.

Can an operator stay inside during a test?

No. Enter only for loading or service under safe conditions; personnel should not remain inside during operation.

Can it test energized equipment?

Only after heat load, electrical interfaces, airflow, failure modes and safety controls are reviewed.

How is humidity performance verified?

Use calibrated sensors at defined locations after stabilization under stated ambient and loading conditions.

Is it delivered as one piece?

It may be integral or panel-assembled. Confirm shipping route, container, doorway and room access.

What water quality is required?

Request the maximum conductivity, pressure, consumption, tank and drain requirements for the selected humidity system.

What is needed for quotation?

Send specimen/load data, temperature-RH profile, room/utilities, ports, doors, monitoring, safety and acceptance criteria.

Configure the 8 m³ Chamber Around the Actual Load

Send DERUI your specimen dimensions, quantity, heat and moisture load, temperature-humidity profile, room access and acceptance criteria.

1. Qual é o princípio de funcionamento da câmara de teste de temperatura e humidade de entrada?
Resposta: Regulando a temperatura através do sistema de refrigeração e controlando a humidade em combinação com o dispositivo de humidade/dehumidade, forma-se um espaço ambiental estável, utilizado para simular o teste de resistência às condições meteorológicas do produto sob diferentes condições de temperatura e humidade.

2. Comparado com câmaras de teste pequenas, quais são as vantagens das câmaras de teste de entrada?
Resposta: É maior em tamanho e pode acomodar o teste de máquinas completas ou equipamentos de grande escala. Suporta monitorização remota; controlo de temperatura independente em várias regiões Atende à necessidade de testes simultâneos por várias pessoas.

3. Quais são os intervalos de controlo habituais para temperatura e humidade?
Resposta: O intervalo de temperatura é geralmente de -70℃ a +150℃, e o intervalo de humidade é de 20% a 98%RH (alguns modelos podem ser expandidos). Os parâmetros específicos devem ser ajustados de acordo com a marca e a configuração.

4. Como escolher o volume adequado da caixa?
Resposta: É determinado com base nas dimensões externas máximas, quantidade e requisitos de espaço de operação do objeto em teste. Recomenda-se geralmente deixar entre 10% a 30% de espaço livre para garantir um fluxo de ar uniforme.

5. O ruído será muito alto durante a operação?
Resposta: O ruído provém principalmente do compressor e do ventilador. O nível de ruído padrão é geralmente ≤65dB (A), e para modelos de alta gama, pode ser reduzido para ≤50dB. Recomenda-se adicionar medidas de isolamento acústico ao instalar perto da área de teste.

6. Como garantir a uniformidade de temperatura e humidade durante testes de longa duração?
Resposta: Priorizar a escolha de modelos com placas defletoras e ventiladores de circulação; verificar regularmente o desgaste das pás do ventilador e se o filtro está entupido. Otimizar o layout interno para evitar bloqueios no fluxo de ar.

7. Como resfriar ou aquecer rapidamente em caso de emergência?
Resposta: Câmaras de teste equipadas com função de proteção de paragem de emergência suportam troca rápida de modo dentro de uma faixa segura, mas é necessário evitar flutuações severas que possam danificar o equipamento. Os limites específicos devem consultar o manual do equipamento.

8. Como operar as funções de gravação de dados e monitorização?
Instrumentos modernos geralmente estão equipados com telas sensíveis ao toque ou sistemas de controlo PLC, suportando desenho de curvas, definição de limites de alarme e exportação de dados via USB ou wireless. Alguns modelos são compatíveis com gestão remota na nuvem.

9. Como proceder em caso de avaria do equipamento para auto-resgate?
Resposta: Desligar imediatamente a alimentação elétrica, verificar o fusível e o sensor. Se houver vazamento ou cheiro desagradável, cortar a fonte de água e solicitar reparação. Profissionais não devem desmontar os componentes internos por conta própria.

10. Como prolongar a vida útil do equipamento?
Resposta: Limpar regularmente o condensador, os orifícios de drenagem e os sensores; substituir as vedações envelhecidas a tempo; evitar arranques e paragens frequentes da unidade; realizar manutenção anual e cuidados conforme recomendado pelo fabricante.

11. Pode ser utilizado diretamente exposto a ambientes inflamáveis e explosivos?
Resposta: Algumas câmaras de teste à prova de explosões suportam condições de trabalho especiais, mas é necessário adquirir modelos que atendam às certificações de proteção contra explosões (como ATEX, IECEx). Modelos comuns são estritamente proibidos de serem utilizados em áreas com riscos de segurança potenciais.

12. O consumo de energia e as tarifas de eletricidade serão muito elevados?
Resposta: O alto consumo de energia concentra-se principalmente na fase de arranque e durante a troca de diferenças extremas de temperatura. Recomenda-se combiná-lo com um sistema inteligente de economia de energia para otimizar o processo de teste e reduzir o tempo de operação desnecessário.

13. Quais são os requisitos para o material de superfície dentro da câmara de teste?
Resposta: A parede interior é revestida com uma camada resistente à corrosão e anti-adsorção (como aço inoxidável 304 ou tratamento com pintura em pó) para evitar afetar as propriedades da amostra e facilitar a limpeza e manutenção.

14. É necessário um local dedicado para a instalação?
Resposta: Deve ser reservado um espaço bem ventilado e plano, sem obstáculos ao redor que possam interferir na dissipação de calor. Ao mesmo tempo, assegure que há fornecimento suficiente de energia e água (a função de humidade precisa de estar conectada a uma canalização de água ou humidificador).

15. Como verificar a precisão de calibração do equipamento?
Resposta: Contacte o fabricante para serviços de calibração de terceiros a cada seis meses. Durante o uso diário, realize comparações cruzadas com termómetros e higrómetros de alta precisão para garantir que a divergência esteja dentro do intervalo permitido.
