摘要

本文以理論分析與實驗量測來對以引擎廢熱回收爲動力的車用空調系統做一探討。其運作係以熱電發電模組將車體所排放的廢熱回收轉換成淨潔電力，來供給熱電致冷模組致冷所需電力，達到車內冷房空調的效果。目標在於節省車輛的油耗。其系統結構包含了熱電發電子系統、電力電子子系統及熱電致冷子系統等三個子系統。系統中所使用的熱電發電與熱電致冷模組都是半導體固態元件，全系統能源轉換過程沒有噪音及溫室氣體排放，這個整合型車用系統具備零噪音、零溫室氣體排放及使用壽命長、淨潔能源等特色。

This report presents both a theoretical analysis and the physical measurement of an experimental set-up for waste-heat recovery from an internal combustion engine (ICE) for reuse in the air-conditioning system of a vehicle. A thermoelectric generator (TEG) is used for recovering the heat to generate electricity. The resulting clean power is used to drive a thermoelectric cooler (TEC) which air-conditions the vehicle. Both the TEG and the FEC are thermoelectric modules (TEMs) consisting of semiconductors with no moving parts. The energy exchange processes of both devices are quiet and emission-free. Therefore, the integrated system has the advantages of silent operation, zero-emission of greenhouse gases, a long lifespan, and clean energy.
