  • Requirement:

Qual./Quant. Must Do: Reach/maintain required temperature, at 108 oF ambient temp, wind, clear sky quantitative Maintain humidity within 20% of target quantitative Temporal/Spatial temperature distribution quantitative Alert System qualitative Run off 120v/240v AC power source. qualitative Full-scale cost under $20,000 quantitative Should Do: Modular qualitative Full-scale cost under $15,000 quantitative Would Be Nice: Solar Powered qualitative Have mobility of some form qualitative Full-scale cost under $10,000 quantitative

Structure and insulation were completely

effective

Difficulties encountered in sealing doors Next iteration should focus on more

efficient refrigeration unit

Produce prototype size without forklift

accessible floor

Gather information from more farmers
