摘要

本研究之主要目的，在於研發一種由跑步機直接傳動冷凍循環系統之製冷製熱裝置之可行性，並驗證跑步機不但具有運動健身之效果，另一方面又可將運動時身體所產生之動能加以利用，藉由冷凍循環之原理可將常溫之水轉換成熱水及冰水可供飲用，即成為運動型冷熱飲水機。
在實驗方面進行三種傳動模式：完全電動傳動、人力加電力傳動與完全人力傳動進行實際之系統測試，以獲得系統製冷製熱效果之相關數據，作為系統性能研究分析的依據。接著將實驗數據以熱力學與熱傳學之基礎建立數學模式進行分析，用來作為驗證實驗之可靠性與評估系統之可行性的參考。
實驗結果顯示，由人體實際測試結果發現跑步約20分鐘，可令 1.3 公斤的水平均溫度下降 15℃，製冷量為 96kJ的冷能，製熱效果上則可使 2公斤的水溫度上升 20℃，製熱量為188kJ的熱能。由上列實驗數據與系統性能分析結果即可證明跑步機所直接傳動之冷凍系統確實能達到運動健身與製冷製熱之雙重獲益，最後並將人體所消耗之卡路里與系統性能指標之間的關係進行比較與探討。

The main purpose of this study is to validate the feasibility of the refrigeration and heating equipment that is a vapor compression refrigeration system driven by a treadmill directly. Furthermore, this equipment not only achieves the goal of maintaining health but also makes the normal temperature water into hot or chiller water bestowing from the kinetic energy during exercising. This kind of equipment taken for drinking purpose is called “Exercise-driven-type Water Dispenser.”
The experiment setup has three experiment modes: Motor only driving mode, Motor combined with Manpower driving mode, and Manpower only driving mode. By carrying through threes experiments, the acquiring data would serve as the basis of performance investigation and further analysis. In the mean time, we establish a mathematical model in order to validate the reliability of experiment data and feasibility of this new type refrigeration system transmitted by treadmills.
The experiment results of testing on the human indicate that running about 20 minutes drops 15℃ of the average temperature in the 1.3 kg water and releases 96kJ cold energy. In terms of producing hot energy, running about 20 minutes raises the water about 20℃ by absorbing 188kJ heat energy. By analyzing both experiment data and performance investigation results, this innovative refrigeration system transmitted directly by treadmills can actually obtain the goal of producing chiller and hot water and exercising for body fitness at one time. Finally, we take discussion and comparison between the calories consumed by humans and the performance parameters of the system.
