汽車空調系統壓力多值少正常 ？汽車空調製冷劑壓力值多少正常？——What is the normal pressure range for air conditioning systems and air conditioning refrigerants?

汽車空調製冷劑正常壓力是: R134a 空調系統壓力正常範圍，表讀數: 低壓側0.15~0.25MPa，高壓則為1.37 ~ 1.57MPa

可以通過連接空調壓力錶檢查空調系統的壓力檢查製冷劑量是否正常

空調壓力錶使用注意事項:

①    連接時，用手而不要用任何工具緊固加注軟管.

②    如果加注軟管的連接密封件損壞，則更換

③    由於低壓側和高壓側的連接尺寸不同，連接軟管時不要裝反

④    軟管和車側的維修閥門連接時，把快速接頭接到維修閥門上並滑動，直到聽到“卡嗒”聲.

⑤ 連接壓力錶時，不要弄彎管道

汽車上空調的高、低壓管路的區分:

管路相對較細，並且檢測口保護蓋上標有“H”的為高壓管:

管路相對較粗，檢查口保護蓋上標有“L”的為低壓管.

The normal pressure of car air conditioning refrigerant is: R134a air conditioning system pressure normal range, meter reading: 0.15 ~ 0.25MPa for low pressure side, 1.37 ~ 1.57MPa for high pressure

You can check the pressure of the air conditioning system by connecting to the air conditioning pressure gauge to check whether the refrigerant quantity is normal.

Notes on the use of the air conditioning pressure gauge.

① When connecting, tighten the filling hose by hand and not with any tools.

② If the connection seal of the filling hose is damaged, replace it.

③ Do not reverse the size of the connection between the low pressure side and the high pressure side.

④ When connecting the hose to the service valve on the vehicle side, attach the quick coupling to the service valve and slide it until you hear a "clicking" sound.

⑤ When connecting the pressure gauge, do not bend the pipe.

Distinguish between high and low pressure lines for air conditioning in vehicles.

A relatively small line with an "H" on the inspection port cover is a high pressure line.

A relatively thick line with an "L" on the inspection cap is a low-pressure line.
