摘 要:汽車空調(diào)是空調(diào)技術(shù)在汽車上的應(yīng)用，是空調(diào)領(lǐng)域的一個(gè)分支。其主要作用是向車室提供舒適的溫度、濕度。隨著社會(huì)經(jīng)濟(jì)的發(fā)展，汽車空調(diào)必將越來越普及，同時(shí)，人們對(duì)其性能的要求也越來越高，汽車空調(diào)正面臨著許多新的課題。 本文針對(duì)制冷量為24KW的大型客車空調(diào)系統(tǒng)介紹了汽車空調(diào)系統(tǒng)設(shè)計(jì)的全過程。本設(shè)計(jì)采用蒸氣壓縮式制冷循環(huán)，制冷劑用環(huán)保型制冷劑R134a，冷凝器和蒸發(fā)器均采用了較成熟的套片式換熱器。本文介紹了：壓縮機(jī)、膨脹閥及其它部件的選取，同時(shí)給出了冷凝器和蒸發(fā)器的設(shè)計(jì)計(jì)算過程。最后本文介紹了汽車空調(diào)系統(tǒng)的控制系統(tǒng)。 關(guān)鍵詞：汽車空調(diào)，蒸氣壓縮式制冷循環(huán)，制冷劑R134a，控制系統(tǒng)，套片式
ABSTRACT:Automobile air conditioning is the application of air conditioning technology on automobile, and it is used to offer a comfortable environment. With the development of social economy, the Automobile air conditioner will be more and more Popular, and its capacity should be improved. Today, Automobile air conditioning confronts many new problems. This article introduces the process of automobile air conditioning system design. This design adopts vapor compression refrigeration, and refrigerant uses a new refrigerant R134a which does less harm to the atmosphere than R12; The condenser and the evaporator uses the tube and band type, and they all are very efficient. This article introduces the quality of R134a and the choose of the compressor , expansion valve and other accessories. This article also introduces the design of condenser and evaporator, and offers a calculating program with friendly interface. Finally, this article presents the control system of this automobile air conditioning system. Keywords: Automobile air conditioning vapor compression refrigeration the tube and band type the fin-tube type |
