Chad

Objective

  • Need to cool beverages while at the beach, with no ice

  • Solution of a Solar Powered Mini-Cooler

  • Not as straightforward as it seems

    • Difficulties in the concept

    • Not only difficult in the concept, but the implementation of the design as well


Design considerations

Spencer

Design Considerations

  • Heat transfer in a Closed System (Controlled Volume)

    • Closed cooler allows for assumption of a simple controlled volume

    • Ambient of up to 35°C

  • Durability of the cooler

    • Drop from 3ft onto concrete, no shock or physical damage

  • Ease of Use

    • Non-confusing controls

    • User adjustable internal temp

    • Easy to clean


Design limitations

Spencer

Design Limitations

  • Need to cool a controlled volume to a specific temp, regardless of ambient

  • Regulate the volume temperature to a user defined, or pre-defined, temperature

  • Cool a maximum of a 2ft3control volume

  • Need to be aware of how much power we can achieve from solar panels

    • Can be limited in the cooling capacity if limited to only panels for power

    • Use of battery packs can give more cooling power, and use when sun is limited

Comparison analysis

Gabe

Comparison Analysis

  • Each of the different concept designs were rated by using a weight comparison table and then compared to each other

    • Rated by using general criteria with different weighted values.

  • The design that has the highest rating would be chosen as the cooler that we choose to build

  • If certain aspects from a lower rated cooler design are useful they may be incorporated into the final design.


Comparison analysis1

Gabe

Comparison Analysis

  • Useable surface area for the solar panels – 30%

    • Must be able to collect sunlight anytime of the day when the sun is out

    • Solar panel area will require around 1000 in2 for 100W worth of panels

  • Maneuverability/Ergonomics – 20%

    • Easy to carry or roll when empty or lightly filled

    • Easy to lift into trunks or backseats as well as storage

  • Efficiency – 30%

    • Walls of the cooler are thick enough to minimize heat conduction

    • Electronics do not interfere with temperature of cooler

    • Constructed in such a way that the least amount of power is required to keep it cool

  • Asthetics – 20%

    • Professional, minimal, and rugged

Summary and recommendation

Jose

Summary and Recommendation

  • Concept one was selected for further development of the solar powered mini cooler and is also the preferred preliminary design

  • This design is simple and should be easy to use for any consumers.


Summary and recommendation1

Jose

Summary and Recommendation

  • Cooling Techniques

  • Multiple Peltier Cooler at low voltages (without fan)

  • Single Peltier Cooler with fans
