摘要

世界之能源消耗是以石油為首的石化燃料，因為燃燒時造成大量溫室氣體的排放，使得全球溫室效應與南北極冰架溶解問題更嚴重，傳統汽車所排放廢熱與佔極大比例，因此新式能源的開發與低污染特性是世界各國發展替代化石燃料的重點。而氫能源就是新超低污染能源，必要時還能達到零污染。而氫能源輸入燃料電池車裡，可大大提升氫能的輸出電力，且燃料電池只會排放水與少許廢氣，回收再利用後，即可達到零污染。
本文針對四種燃料電池在巴士車輛空調系統作性能分析，即利用燃料電池電力之電動汽車，利用蓄電池來分配電力給傳動系統與輔助系統與燃料電池的廢熱提供給小型單效吸收式當作空調來源，繼而跟傳統壓縮式空調做比較，分析電力、冷凍能力、總效率與續航力各COP值，以其提供最佳系統減碳節能特性。

The leading energy consumption in the world is the petroleum of petrochemical based fuel. Since the vast amount release of greenhouse gas resulted from fuel combustion, it renders the global greenhouse effect more serious and damaging than that from the iceberg melting from both the north and south poles of the earth. And the vast majority of the discharged exhaust heat is from traditional automobile, hence, the new energy development and its associated low emission characteristics are the essence of developments to replace petrochemical based fuels by all nations in the world. Nonetheless, hydrogen energy could well be the new energy source with extreme low emission; if necessary, it could reach the level of zero emission. Additionally, hydrogen energy can be inputted into the fuel battery for the automobile which can massively enhance the output electricity for the hydrogen energy. Nevertheless, fuel battery only discharges water and somewhat waste gases and after recycling, it can reach the state of zero emission.
This thesis conducts functional analyses in regards to the application for air conditioning system in the bus by using four types of fuel batteries, i.e. by using the electric car’s fuel cell power. It can use the storage battery to distribute the electricity to the transmission system as well as the auxiliary system. In addition, the heat waste from the fuel cell can provide as the source of air conditioning power for the small sized single effect absorption. Moreover, the comparisons between the traditional compressor of the air conditioning and this type of application were made to analyze the COP (coefficient of performance) values for electric power, condensing capability, total efficiency and sustaining power so as to provide the optimum characteristics for systemic carbon minimization and energy saving.
