Development of Practical Unit of Thermal Controllable Chair and Installation of Fan Speed Fluctuation Function

Abstract

In the first part of this paper, we summarize the issues involved in the practical application of a thermal controllable chair and describe the process of solving these issues. The performance requirements for the fixture were seating comfort, usability, safety, durability, manufacturability, and maintainability. We aimed to address each of these needs by matching the function of thermal control and the performance as a fixture with fixture manufacturers. Finally, a practical specification was developed. In the latter part of this paper, we present the implementation of a variable airflow function in thermal controllable chairs. The 1/f fluctuation was theoretically generated and implemented in a practical machine. The trial evaluation indicated a favorable evaluation. However we found some problems with sound were noted.
