The reason why there is no refrigeration after replacing the air conditioning filter screen is the operation error:

　　1、空調(diào)開(kāi)關(guān)不開(kāi):你要知道空調(diào)開(kāi)關(guān)是空調(diào)，有些新車(chē)車(chē)主很可能會(huì)犯這樣的錯(cuò)誤。

　　1. Air conditioning switch does not open: you need to know that the air conditioning switch is air conditioning, some new car owners are likely to make such a mistake.

　　2. 出風(fēng)口關(guān)閉或風(fēng)向不對(duì):首先要確保出風(fēng)口是開(kāi)著的，沒(méi)有異物堵住出風(fēng)口。另外，你應(yīng)該知道出風(fēng)口的風(fēng)向調(diào)節(jié)。

　　2. The air outlet is closed or the wind direction is wrong: first, make sure that the air outlet is open and there is no foreign matter blocking the air outlet. In addition, you should know the wind direction regulation of the air outlet.

　　3.天氣炎熱時(shí)的外循環(huán):此時(shí)，外循環(huán)無(wú)疑會(huì)導(dǎo)致熱空氣從外面進(jìn)入車(chē)內(nèi)，空調(diào)的制冷效果自然會(huì)變差。因此，在天氣炎熱、無(wú)特殊情況下，應(yīng)盡量采用內(nèi)循環(huán)方式。

　　3. External circulation in hot weather: at this time, the external circulation will undoubtedly cause hot air to enter the car from the outside, and the cooling effect of the air conditioner will naturally become worse. Therefore, in the hot weather, without special circumstances, we should try to use internal circulation.

　　4. 當(dāng)汽車(chē)處于高溫狀態(tài)時(shí)，打開(kāi)空調(diào):特別是長(zhǎng)時(shí)間暴露在烈日下的車(chē)輛，記得先打開(kāi)窗戶(hù)讓熱空氣出去，然后再打開(kāi)空調(diào)。

　　4. When the car is in a high temperature state, turn on the air conditioner: especially for the car exposed to the hot sun for a long time, remember to open the window first to let the hot air out, and then turn on the air conditioner.

　　5、室外溫度過(guò)低，導(dǎo)致空調(diào)不工作

　　5. The outdoor temperature is too low, resulting in the air conditioner not working

　　不制冷解決方案:

　　Uncooled solution:

　　1.選擇正常的維修店和正常的產(chǎn)品，濾網(wǎng)堵塞時(shí)，就必須選擇合格的制冷劑進(jìn)行維修，合格的制冷劑在汽車(chē)空調(diào)中起到了關(guān)鍵的作用。

　　1. Select normal maintenance shop and normal products. When the filter screen is blocked, qualified refrigerant must be selected for maintenance. Qualified refrigerant plays a key role in automobile air conditioning.

　　2.有時(shí)汽車(chē)空調(diào)中的制冷劑不足或太少，會(huì)導(dǎo)致汽車(chē)空調(diào)制冷失效，而汽車(chē)空調(diào)不足的原因大多是由于系統(tǒng)中制冷劑的少量泄漏造成的。

　　2. Sometimes the refrigerant in the air conditioner is insufficient or too little, which will lead to the refrigeration failure of the air conditioner, and most of the reasons for the lack of the air conditioner are caused by a small amount of refrigerant leakage in the system.

　　3.在整個(gè)汽車(chē)空調(diào)系統(tǒng)中，冰箱中制冷劑和機(jī)油過(guò)量也會(huì)導(dǎo)致汽車(chē)空調(diào)過(guò)濾網(wǎng)堵塞，導(dǎo)致汽車(chē)空調(diào)不制冷。它的阻力會(huì)增大，制冷劑到膨脹閥的流量也會(huì)減小，導(dǎo)致制冷量不足。

　　3. In the whole automobile air conditioning system, too much refrigerant and oil in the refrigerator will also cause the filter screen of the automobile air conditioning to be blocked, which will cause the automobile air conditioning not to refrigerate. Its resistance will increase, and the flow of refrigerant to the expansion valve will decrease, resulting in insufficient cooling capacity.

　　4.汽車(chē)空調(diào)壓縮機(jī)的傳動(dòng)皮帶松了,壓縮機(jī)工作時(shí)將滑動(dòng),導(dǎo)致傳輸效率的降低,減少壓縮機(jī)的轉(zhuǎn)速,和輸送壓縮制冷劑的減少,從而導(dǎo)致汽車(chē)空調(diào)制冷的失敗。

　　4. The transmission belt of the automobile air conditioning compressor is loose, which will slide when the compressor works, resulting in the reduction of transmission efficiency, the reduction of compressor speed, and the reduction of transmission of compressed refrigerant, thus leading to the failure of automobile air conditioning refrigeration.
