汽车空调的制冷剂量直接影响到制冷效果。空调制冷系统抽真空后,加注制冷剂量可按使用说明书规定,如一般小客车为800g左右。但因泄漏原因或马虎修理引起制冷剂在系统中的存量低于或高出说明书规定的量,可通过动态检查方法来判断。检验时,保持发动机快怠速运转,打开制冷开关,使制冷系统工作,把开关开到最高档位,并运转数分钟,然后观察玻璃检测口,以确定制冷剂的注入、排出量。
Refrigeration air-conditioned car directly affects the cooling effect. After the air conditioning and refrigeration system is evacuated, the amount of refrigerant can be increased according to the instruction manual, for example, an ordinary passenger car is about 800g. However, due to leakage or sloppy repair refrigerant inventory in the system below or above the amount specified in the instructions can be determined by dynamic inspection methods. During the test, keep the engine running at idle speed, turn on the cooling switch, make the refrigeration system work, turn the switch to the highest gear and run for a few minutes, and then observe the glass test port to determine the amount of refrigerant injected and discharged.
