【正文】 conditioning system as the main assembly affect auto fort, one of the passengers ride provides a good environment, and to use and maintenance of the automobile airconditioning and some other technical problems bring new challenges. This article through to related material, summarized study materials, further deep for automotive air conditioning system structure working principle and simply introduces detection. Paper finally to automotive air conditioning breakdown maintenance method, and maintenance of automotive air conditioning for simple case to the discussion of automotive air conditioning system, understand, and use in practical work.
