電動車用區域性空調系統研發
The Development of Regional Air-Conditioning System inside an Electric Vehicle
摘要
考量車艙人員舒適度與電動車輛續航力之需求，本研究針對人員的生理、心理層面與安全方面之人因需求，進行車艙各項參數（出風吸口位置、風速、角度、及溫度）的模擬研究，並建立3-D的車艙模型與理論數學模型，利用CFD軟體-FLUENT發展區域性空氣流管理技術，來控制車艙內的空氣流場結構，將熱量及物質控制在某一個區域內，且區域之間不需以實物隔開，在雙人乘坐時可達成個人化區域舒適度控制，單人乘坐時可降低空調系統資源的浪費，達到省能的效果。電動空調系統藉由MATLAB軟體估算車艙熱負載與動態模型建立分析得知各元件的效益以及電動車的里程數，並以負壓艙效應降低車內熱負載而提高空調冷房效率，使得車艙溫度可達到一最佳安全舒適之環境，藉以提高電動車之續航力，透過本系統之開發，未來可轉移到符合人員需求之電動車輛空調系統發展，以達到車輛節能、低污染與提高市場接受度之目的。

The comfortableness for car cabin staff and the range ofthe electric vehicle should both be taken into consideration in this research. The main focus of this research will be on the ergonomic demand of the car cabin staff in terms of their physiology, psychology and safety, and then study the simulated parameters of the vehicle cabin (the position of the air outlet, wind velocity, angle and temperature). Furthermore, to build up a 3-D model of the vehicle cabin and a mathematical model, and then making use of the CFD software – FLUENT – to develop the management technique of regional air-conditioning system, which can control the structure of the air-flow within the vehicle cabin, gathering the heat and substances in a specific region without any solid division between each region. It can help to achieve the goal of controlling the level personalized regional comfortableness when two people are in the vehicle, and when there is only one person, it can help to reduce the waste of energy of the air conditioning system, thus to achieve the effect of power-saving. Through the MATLAB software, the electric automatic air-conditioning system can estimate the heat load of vehicle cabin, and based on the result of analysis to understand the efficiency of each component as well as the odometer of the electric vehicle. And then make use of the negative pressure chamber effect to reduce the heat load within the cabin, in other words, to raise the air conditioner’s EER for cooling, in this way to build a safest and most comfortable environment within the vehicle cabin in terms of the temperature. The final goal of this research is to increase the range of electric vehicle. Through the development of this system, it can be expected that in the future there will be more studies of the air-conditioning system of electric vehicle which satisfies the needs of staff, and achieve the goal of power-saving, low pollution and increasing the acceptance level of the market.
