Analysis and repair: The machine had been installed for more than a month when the frequent shutdown phenomenon occurred. It was in the peak of summer, so it was analyzed that this phenomenon was mostly caused by poor heat dissipation or unstable power voltage. After inspection, the machine was installed on the roof where the heat dissipation effect was not very good, but it was still not enough to cause frequent shutdowns, and the power voltage was basically normal. Suspecting that the problem was installation-related, the system was then thoroughly checked. An unstable gauge pressure and compressor overheating were discovered, preliminarily judging that air was not completely expelled during installation. After re-evacuating and adding refrigerant, the cooling effect was excellent with no frequent shutdowns.
