  2. Preview • Project Background • PDS Summary • Internal Search • External Search • Design Evaluation • Current Progress

  3. Project Background • Objective: • Produce a retrofit-able sealant oven capable of controlling humidity and temperature that allows for more efficient flow control • Current Methods: • Large size - inefficient flow control • Anchored to floor - Costly to move

  4. PDS Summary • Performance • RH 50 ± 5% @130 ± 5 oF • Un-plumbed • Ergonomics • < 35 lb supply

  5. Internal Search • Atomizing water • Advantages • Inexpensive • Suitable for lower temperature and lower humidity • Disadvantages • Droplet/moisture formation • Temperature change

  6. Internal Search Cont. • Steam injection • Advantages • Higher RH (100%) • Dry process • No temperature change • Disadvantages • Delay initial steam supply • More complex design • Expensive (steam generator)

  7. External Search • Boeing’s traditional humidity controlled oven • Steam injection • Humidity control • Over sized-poor flow control • Plumbed system

  8. External Search Cont. • Green roof simulator • Measures effective R value for green roofs • Simulates environmental conditions • Utilizes steam injection / RH controls

  9. Design Evaluation Concept Scoring Matrix Scores from 1 to 5, 1 being the lowest. Scores multiplied by weight factor to determine the total score

  10. Current Progress Steam injection Design: Including on board water supply, steam generator and controls
