Solar hot water system design for modular bathrooms for Tohono O’odham
Course: 22.521 - Solar Fundamentals
Semester: Fall 2007
Instructor: John Duffy
Partner:Tohono O’odham reservation and the TOCC
This project involved the detail design of a solar hot water collector that would be suitable for the Arizona climate and that could eventually be built locally by the students in AZ at the Tohono O’odham Community College (TOCC). The Solar Fundamentals students were able to specify the type of glazing to be used (and how many to use), the type of absorber plate needed (including the necessary special coating), how much insulation would be needed, the frame layout, the tubing and the spacing necessary between the tubes. The students drew detailed sketches of the construction of the collector for future use by the TOCC students, and they also estimated the designed collector’s characteristic parameters that represent the efficiency and the losses experienced by the collector.
