color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">客户反应开空调,空调不工作,经检查压缩机不吸合。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">首先,车辆正常着车,在空调打开鼓风机,打开AC,鼓风机工作正常,但是没冷风出来,前面无离合器吸合声音。其可能的原因有:1. 管路内无冷媒,系统没无压力2.压力开关损坏,导致信号无法传递至ECU3.蒸发箱温度传感器/环境温度传感器4.发动机内有其他的故障码5.压缩机本身故障,电磁离合器故障6.压缩机继电器和线路断路7.压缩机控制线路断路8.空调面板损坏9.发动机ecu损坏,无法控制继电器吸合</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">首先确认不制冷为压缩机不吸合,那我们要检查的方向就是压缩机吸合条件,和压缩机的执行线路,我们第一时间使用空调压力表,检查下管路里是不是有正常的压力。系统内有没有冷媒。<br style="box-sizing: border-box; outline: 0px !important;"><img decoding="async" src="https://wapq.cn/wp-content/uploads/2025/03/IMG_2632-1024x768.png" alt="IMG_2632" data-edit-file-id="185" data-full-url="https://wapq.cn/wp-content/uploads/2025/03/IMG_2632.png" imgbox-index="1" style="box-sizing: border-box; outline: 0px !important; border: 0px; vertical-align: middle; max-width: 100%; max-height: 100%; height: auto; display: block; margin: auto;"></p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">1.冷媒压力,低压9bar,高压9bar。符合压缩工作条件,系统内有冷媒。2.检测压力开关,开关为4线制,1号、3号都有12V,使用万用表确认,当前压力下1-4导通,2-3不通,我们短接1-4,故障依旧。<img decoding="async" src="https://wapq.cn/wp-content/uploads/2025/03/IMG_2633.png" alt="IMG_2633" data-edit-file-id="183" data-full-url="https://wapq.cn/wp-content/uploads/2025/03/IMG_2633.png" imgbox-index="2" style="box-sizing: border-box; outline: 0px !important; border: 0px; vertical-align: middle; max-width: 100%; max-height: 100%; height: auto; display: block; margin: auto;"></p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">3.我们用进入空调系统,没有任何故障码,解码器读取数据流:环境温度29°、蒸发箱温度34°,环境温度和蒸发箱温度显示正常,排除相关传感器故障。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">4.电脑内无任何故障码,系统内没有读取到异常数据,排除其他有关数据导致ECU停止压缩机工作。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">5.我们检测压缩机继电器无吸合,使用导线短接继电器的30-87,压缩机吸合,且正常制冷。可以排除压缩机、压缩机保险及继电器到压缩线路问题。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">6.检测压缩机的控制脚,在打开压缩机的情况下,没有负极控制,正极脚有电,直接通电继电器,继电吸合。问题在发动没有控制吸合。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">7.压缩机的控制脚,到电脑42针脚,线路电阻为0.2欧姆。线路正常无断路。<br style="box-sizing: border-box; outline: 0px !important;"><img decoding="async" src="https://wapq.cn/wp-content/uploads/2025/03/IMG_2634.png" alt="IMG_2634" data-edit-file-id="184" data-full-url="https://wapq.cn/wp-content/uploads/2025/03/IMG_2634.png" imgbox-index="3" style="box-sizing: border-box; outline: 0px !important; border: 0px; vertical-align: middle; max-width: 100%; max-height: 100%; height: auto; display: block; margin: auto;"></p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">8.根据电路图所示,空调面板通过10#给压力开关信号,通过压力开关,告诉需要压缩机运行,经检查,打开AC开关式。1号为13V,关闭AC开关时1号为0V,可以判断面板没有问题。(电路图,1-3通,实测为1-4通)9.在电脑版24针脚确认开空调有13V信号进来,但是ECU并未执行压缩机工作,加上上述检修流程判断为电脑版损坏。更换电脑板后,压缩机正常工作。</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">故障总结</p><p style="box-sizing: border-box; margin-bottom: 20px; color: rgb(78, 83, 88); font-family: &quot;Helvetica Neue&quot;, Helvetica, Arial, sans-serif; font-size: 16px; outline: 0px !important;">空调的故障是夏天检修最多的故障,其牵扯传感器广泛,问题繁多,所以能够快速诊断空调的电路故障,是修理工必须要掌握的技能。</p><p></p>
