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
Presentation Agenda 1. Introduction and background 2. Method a. Concept Generation b. Concept Selection 3. Schedule and Budget
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
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
Constraints Size and geometry of unit and enclosure. Regulatory commission specifications. (ARI, UL)
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.
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
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
Insert high manufacturing cost long time to fabricate Drain Pan Concept Selection
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
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
Final Two Room Draw Concept • Duct underneath condenser coil
Estimated Engineering Time • FPED • 4 hours building • 24 hours testing • The Whalen Co. • 5 additional hours to implement final concept
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
