  1. Members Sean Gallagher Pamela McDowell Brian Davison Prathana Vanarath Sponsors Dr. Wexler Dr. Advani Advisor Dr. Keefe Team 10Air Conditioning Experiment

  2. Presentation Overview • Introduction • Method • Concept Generation • Concept Selection • Schedule & Budget • Questions

  3. Project BackgroundNew Curriculum for Mechanical Engineers “ME 2000 Curriculum” • Joint Laboratory Classes for Thermodynamics and Heat Transfer classes • We must investigate 2 aspects of this issue: • Single lab apparatus for multiple labs (Hardware) • Increased understanding of Thermodynamic and Heat Transfer fundamentals (Lab Experiments)

  4. Mission • Design a set of thermodynamic and heat transfer experiments for the University of Delaware Mechanical Engineering Undergraduate Laboratory, using a window air conditioner, that will be completed by April for approximately $4000.

  5. Identifying customer(s) wants needs constraints. Benchmark to identify competitors metrics possible solutions. Generate concepts Compare, eliminate, expand and synthesize possible solutions based on the metrics. Proceed to a Go/No-Go review of the concepts. Build and test a prototype. Approach

  6. Dr. Wexler Dr. Advani Undergraduate students Graduate students Judy Green: Educational Dr. Sun William Davison Manufacturers: Hampden, Armfield Ltd. Other Schools: Georgia Tech, Penn State Effective learning tool Easy to Use Self Evident Easy to set up Cost Effectiveness Multiple Purposes LabView compatible data acquisition Forgiving of incompetence Quiet Quick CustomersWants

  9. Hardware Develop a lab apparatus using a window air conditioner and sensors Develop a Data Acquisition Program Lab Experiments Develop a set of experiments that include a variety of Thermodynamic and Heat Transfer Principles Problem Description

  10. Systems Benchmarking(Major Competitors) • Hampden Basic Refrigeration Cycle Trainer • Hampden Basic Refrigeration Cycle and Heat Pump Trainer • Hampden Refrigeration Demonstrator • Hampden Heat Pump Trainer • Armfield Heat Exchanger Training Equipment Series • Armfield Heat Transfer Teaching Equipment Series • Armfield Temperature Measurement Bench • Others

  11. Functional Benchmarking • Omega Engineering - Sensors • Carries every type of sensor we will require • Catalogs are an excellent technical reference • Optrand - Sensors • Fiber-optic pressure transducer • Air Conditioning Manufacturers - AC units • University of Delaware HVAC - sample AC

  12. Easy to Use Visible Components Physically look at chosen apparatus and rate 1 - 10, target value 10. Accessible Components same as above Cost Effectiveness Low initial price Target value $4000 Low operating cost Target value $22. Durable Target value 10 years Parts availability Target value: 2 week lead time Metrics

  13. Self Evident Clear Lessons/Objectives Survey scored 1 - 5: target value 5 Logical Procedure Survey scored 1 - 5: target value 5 Quiet Low noise level Target value of 60 dB Effective Learning Tool Fun Number of Fundamentals Clear Lessons/Objectives Real World Connection to Students Keeps Students’ Interests Hands-on/Interactive All are evaluated yes or no, the target value is yes. Metrics Cont’d

  14. Quick Time Target Value within set lab time (2 hrs) Easy Maintenance Parts visibility Physically look at chosen apparatus and rate 1 - 10, target value 10. Parts availability Target value: 2 week lead time Forgiving of Incompetence Years of experience Target value 2 years engineering experience Easy to set up Time Target value 15 minutes Self Contained Target value 1 Metrics Cont’d

  15. Apparatus Concept Generation and Selection Concept Lab Reports Hardware Number of Experiments Presentation of Lab Reports Sensors Overall Presentation of Experiments

  16. Concept Generation and Selection Number of Experiments 1 Experiment 4-7 Experiments 13 Experiments

  17. 4 - 7 Experiments Easy to set up More effective learning tool than  and  Multiple Purposes One Experiment using different sensors Not an effective learning tool Difficult to set up Number of ExperimentsGeneration and Selection • 13 Experiments • Easy to set up • More effective learning tool than  • Multiple Purposes

  18. Concept Generation and Selection Overall Presentation of Experiments By Component By Fundamental

  19. By Fundamental Self Evident: clear lessons Quick: can be completed in lab time By Component Self Evident: clear lessons Quick: can be completed in lab time More effective learning tool than  Overall Presentation of ExperimentsGeneration and Selection

  20. Concept Generation and Selection Presentation of Lab Reports Standard Lab Reports Short Lab Reports + Technical Paper

  21. Standard Lab Reports Self Evident: clear lessons Short Lab Reports & Technical Paper Self Evident: clear lessons More effective learning tool than  Presentation of Lab ReportsGeneration and Selection

  22. Concept Generation and Selection Apparatus Air Conditioning Unit Other

  23. Other Quick: can be completed in lab time Easy to set up: can be set up in less than 15 min. Air Conditioning Unit Quick: can be completed in lab time Easy to set up: can be set up in less than 15 min. More effective learning tool than  More self evident than  Easier to use than  More cost effective  ApparatusGeneration and Selection

  24. SensorsGeneration and Selection • Fully Instrumented with Redundancy • Most expensive • Fully Instrumented without Redundancy • Most feasible • Economically Instrumented • Least expensive but sacrifices functionality

  25. Updated Concept Flow-Chart

  26. Number of Experiments 4 - 7 Experiments Overall Presentation of Experiments By Components Apparatus Air Conditioning Unit Presentation of Lab Reports Short Lab Reports & Technical Paper Sensors Fully Instrumented without Redundancy Final Concept Selection

  27. Working Model • Lab Experiments • See Handout • Air Conditioner • See apparatus

  28. Wanted to be here: Develop Heat Transfer Lab Fundamentals Develop Thermodynamic Lab Fundamentals Investigate Educational Values/Criteria Evaluate Key Equations Obtain Sample Air Conditioner for Study Examine Possible Sensor Placements We are here: Applied Heat Transfer fundamentals to labs Applied Thermodynamic fundamentals to labs Researched and applied these values to labs Lab write-ups made Sample Air Conditioner used in determining labs Possible locations determined Actual Progress

  29. Not Too Detailed Schedule • January • February • Compile and finalize lab manuals • Select and purchase required equipment • March • Assemble lab apparatus • Test and evaluate labs • April • Complete project
