Re:
Build proposal, budget and winter gantt chart
Dr. Hubbard,
As per your request, I am pleased to submit the build proposal for a Residential Comfort Cooler on behalf of Design
Team #11. This document includes a brief device background, a list of undetermined variables, CAD drawings, winter
Gantt chart, and a budget.
The purpose of our device is to improve the environmental comfort levels of a partially enclosed area; more specifically,
this device is intended for use in tropical environments of higher humidities. The key principles upon which the cooler
will function are air circulation throughout the area and evaporative cooling.
It is important to note that there are still important aspects of the design that have yet to be finalized. These aspects are
as follows:



Fan size
Pump size
Number of nozzles
While these factors will affect the final design, they have been overestimated in this document. That is, if any changes
are necessary, they will entail reductions in size or complexity.
Included are drawings of the following:





Top, side and front views of the device
Reservoir tank detail
Frame isometric detail
Frame, chamber and fan assembly isometric detail
Frame, piping, pump and reservoir isometric detail
The Gantt chart and budget are located after the CAD drawings.
Sincerely,
Ewan Fraser
for Design Team # 11

Frame:
 Dimensions may change slightly based on sizing of fan.
 Shown are the MAXIMUM dimensions.
 All angles are at 90 degrees.
 Material: Angle Iron or Square Tubing (Aluminum or Iron).
 Assistance required: Welding and Shaping.
Frame, Chamber, Fan and Baffle Assembly:
 Page 2
 Fan and Baffle will be purchased.
 Materials: Light steel or plastic for Evaporation Chamber (blue in above Diagram).
 Assistance Required:
o Holes to install brackets to stabilize Chamber, Fan and Baffle against Frame.
o Holes in Evaporation Chamber sized for our Nozzles (45 degree intervals).
o Possible mounting of Fan to Frame.
Frame, Piping, Pump and Reservoir Assembly:
 Page 3
 Pump, Nozzles and Elbows/T’s will be purchased.
 Materials:
o Flexible Plastic Hose (Navy Blue in Figure)
o Rigid Pipe (Copper or PVC) or Flexible Plastic Hose (Magenta in Figure)
o Plastic or Sheet Metal for Reservoir under Evaporation Chamber
 Assistance Required:
o Holes in Evaporation Chamber for Nozzles
o Brackets welded to frame to support Piping
o Possible Welding of Reservoir
