【正文】 裝置。 ） 第五階段 微機控制。自從冷暖一體化出現(xiàn)后，通用公司就著手研究自動控制的汽車空調(diào)，并于 1964 年首先安裝在卡迪拉克牌轎車上，緊接著通用、福特、克萊斯勒三大汽車公司競 相在各自的高級轎車上安裝自動空調(diào)。隨著汽車空調(diào)技術(shù)的改進(jìn)，目前的冷熱一體空調(diào)基本上具有降溫、除濕、通風(fēng)、過濾、除霜等功能。歐洲、日本到 1957 年才加裝這種單一冷氣轎車。 第二階段 單一冷氣。到 1927 年發(fā)展到具有加熱器、風(fēng)機和空氣濾清其的比較完整的供熱系統(tǒng)。s living standard, car entered families. People always in pursuit of automobile safety, reliability, at the same time, also pay more attention to the requirements of fort now. Therefore, air conditioning system as a basic equipped with modern cars, became inevitable. The function of auto air conditioner is through the way of thought to create a suitable environment to the human body. Automotive air conditioning refrigerating system, heating system, ventilation system, the operation control system and air purifying system. This article on automotive air conditioning refrigerating system, problems existing in the use of the ponents of the refrigeration system are analyzed, the working principle, mon failure and later maintenance and maintenance, etc. Fault inspection and related professional equipment, analysis the cause of the problem, based on the practical maintenance. And about automotive air conditioning refrigerating system mon fault diagnosis methods and processes.
