A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. Then, after-sales maintenance sometimes doubts that the compressor is malfunctioning, how to check and judge at this time 器2 䀀 ᅵ皥 䖒皦즠Ʋ煔क़ 㲈Ʋ 䌁皦 ᮔDž༬皧煞क़Ѐ 呄ᠾ鹨់༹皧 ࠄ 00령ꐱ댁珵뛐珵Љ 䕄ྦ 뤂ᐱ뚜珵 ᴴᏩ呄ᠾ퍘ᒥ 鹨់ᩄ ꋔྦ 瑉浥 巠皱㙲皦抐皱 巠皱 ੨皦柘皱 ᅵ皥

What happens if the refrigerant recovery time of the air-conditioning compressor is too long At ordinary times, we will need to simply disassemble and assemble the compressor due to certain circumstances. However, if you do not pay attention to certain matters when disassembling, it will cause the compressor to be directly damaged, so you will not be able to compensate for it.
