  1. Four Points Engineering and Design Project 99.04: Heat Pump Design for Whalen Co. FPED Team Members: Ricardo Blackett, Andy Parke, Scott Quirico, Brian Zigmond

  2. Presentation Agenda 1. Introduction and background 2. Method a. Concept Generation b. Concept Selection 3. Schedule and Budget

  3. Background • The Whalen Co. • HVAC manufacturer • hospitals, apartment complexes, hotels • Boost sales of vertical water source heat pump • offer additional options • offer improved health quality

  4. Mission and Approach 1. Eliminate standing water 2. Decrease unit’s noise level 3. Improve circulation in the two-room units Present FPED’s Solution to Whalen Co. Develop Concept • Produce a unit that: • eliminates standing • water • is quieter • has improved room • circulation

  5. Constraints Size and geometry of unit and enclosure. Regulatory commission specifications. (ARI, UL)

  6. Customers and Wants

  7. System Benchmarking • Trane: Well insulated unit gives quiet performance, removable drain pan for easy maintenance. • ClimateMaster: Removable chassis for easy maintenance, sound-suppressing baffles on intakes.

  8. Drain Pan sheet metal guide positive pitch pump evaporation Sound neoprene pads isolate insulate external baffles Two Room Draw return grilles sheet metal ducting Functional Benchmarking

  9. Quality Metrics & Target Values

  10. Concept Generation

  11. Sound diffusion ducting isolation insulation Drain Pan sloped insert channel Two Room Air above the coil below the coil adjacent to coil rotate coil Partial Concept Generation

  12. Insert high manufacturing cost long time to fabricate Drain Pan Concept Selection

  13. Final Drain Pan Concept

  14. Sound Attenuation Concept Selection • Diffusion Ducting • Not applicable • Insulate and Isolate • every metal to metal vibration point • double insulate cabinet • Testing • which points need isolation • optimum insulation thickness

  15. Rotate Coil changes footprint Above Coil difficult to maintain/repair Adjacent to Coil additional parts additional manufacturing costs minimal air changes per hour Two Room Draw Concept Selection

  16. Final Two Room Draw Concept • Duct underneath condenser coil

  17. Overall Final Concept

  18. Past Schedule

  19. Future Schedule

  20. Estimated Engineering Time • FPED • 4 hours building • 24 hours testing • The Whalen Co. • 5 additional hours to implement final concept

  21. Project Budget • Total Budget = $5000 • Expenditures to date • gas for trip to Whalen $11.31 • photographs taken during visit $ 9.29 • model materials(foam core) $ 9.99 • Future Expenditures • decibel meter $45.00 • battery 12 V $10.00
