摘     要
 隨著石油的不斷減少和漲價，世界低碳生活的呼聲越來越高，電動汽車的發(fā)展已成為一種必然的趨勢，由于純電動汽車不依賴石油為動力，而且具有零排放的優(yōu)點(diǎn)，目前受到各國政府的高度重視，空調(diào)作為汽車中一個必不可少的配置，在電動汽車中同樣重要。本次設(shè)計結(jié)合現(xiàn)有知識和技術(shù)對電動汽車空調(diào)系統(tǒng)進(jìn)行設(shè)計設(shè)計研究。
  本文首先簡單講述了電動汽車空調(diào)的組成，驅(qū)動方式及功能，并根據(jù)此對汽車空調(diào)進(jìn)行一個總體的設(shè)計，然后進(jìn)行了汽車?yán)湄?fù)荷的計算并進(jìn)行壓縮機(jī)的參數(shù)匹配及選型。從整車制冷及設(shè)計布置要求對冷凝器，蒸發(fā)器，膨脹閥深入研究計算，最終確定其尺寸大小和各項(xiàng)參數(shù)。最后在完成汽車空調(diào)系統(tǒng)最主要的幾個組成部分匹配設(shè)計之后簡要介紹了此次設(shè)計中選用的汽車制熱系統(tǒng)及風(fēng)道設(shè)計。

The Design of Electric Vehicle Air Conditioning

Abstract
With oil prices declining and the world's increasing demands for low-carbon life, the development of electric vehicles has become an inevitable trend, as pure electric vehicles is not dependent on oil as the driving force, but also has the advantages of zero emissions, currently subject to national government attach great importance, air-conditioning as an essential vehicle configuration, the electric car is equally important. This design combined with existing knowledge and technology to design electric vehicles air conditioning system design study.  First, this article about the electric car air-conditioning composition, form and function-driven and based on this on auto air conditioning for an overall design, then the car cooling load calculations and the parameters to match the compressor and selection. Design layout from the vehicle and require refrigeration condenser, evaporator, expansion valve in-depth study calculating the size and determine the parameters. Finally, the completion of several major automotive air conditioning system components match the design brief, after the selection of the design of heating systems and automotive air duct design.
