Progress Blog #4
Blog Entry #4: During the period between April 9th and 23rd, we accomplished several key aspects of our design for the spring semester. We made a mathematical model of our water loop system and how it interacts with the surface of the chair. Also, we created a 3D-CAD model of our thermoelectric cooler (TEC) Peltier system and how it will fit together. Figure 1: Model of chair showing pipes and waterloop. This model simplifies the system by taking a 2D slice of the chair cushion with the waterloop installed. The pipes are cut across their cross-sections. The layers of the chair and waterloop are shown in green. Nodes are marked in red. The center to center distance of the end pipes is the distance 0 to L along the surface of the chair. We want to maintain a constant comfortable surface temperature of approximately 22°C. When a person rests on the seat, the surface will have a constant heat flux of approximate...
