Heat Pump Design Team 4 –Ricardo Blackett : blackett@udel.edu –Andrew Parke : aparke@udel.edu –Scott Quirico : scottq@udel.edu –Brian Zigmond : bzigmond@udel.edu Customer: Whalen Co.Advisor: Dr. Keefe Mission: In eight and a half months, to improve the Whalen Co. Vertical Heat Pump by eliminating standing water, decrease the noise level, and draw air from both rooms being conditioned. Approach: Through the use of competitive benchmarking, FPED’s knowledge, and Whalen’s field expertise, to create an improved vertical heat pump design that comfortably satisfies the general needs of everyone.

4. Project Background By 2000, ARI will require that no standing water be allowed in HVAC systems. This prompts Whalen Co. to redesign the current condensate drip pan in their vertical water source heat pump While solving this problem, they decided to address some others, as well...

5. Problem as presented to FPED Eliminate the standing water in the condensate drain pan of the unit. Improve the circulation in the “two room” units. Lower the operating noise level.

6. Benefits The new drain pan will be in accordance with ARI standards, as well as reducing the chances of health risks due to stagnant water. The “two room” return air draw will allow Whalen Co. to be more competitive in the industry. A quieter unit will bolster sales.

8. Preliminary Constraints size –Whalen’s current package design regulating agency standards –American Refrigeration Institute –Underwriters Laboratories Inc

9. Budgeting Mr. Christopher Whalen has agreed to “provide a unit and any and all materials needed within reason.” We are awaiting more information as to what “within reason” means more specifically.

10. Main Competitor #1 The Trane Company Flush-mounted, hinged panel for quality sound attenuation Convenient serviceability Adjustable risers to accommodate varying height constraints.

11. Main Competitor #2 ClimateMaster 816 Series 45 return air/discharge air options Three return air panel options for optimum sound dissipation Removable refrigerant chassis for easy access to the drain pan along with the other components Optional acoustical return air Panels
