The unit did not trigger any alarms; why did the safety valve activate?
Thread Content
When the refrigeration unit was started, no alarm was triggered for the high discharge pressure; however, for some reason the safety valve of the condenser opened, resulting in a large amount of Freon and oil leaking out. I would appreciate it if any expert could help explain this phenomenon. Thank you!
It’s possible that the setting for the safety valve’s operating pressure is incorrect, causing it to activate before reaching that pressure; it’s best to consult the manufacturer. Waiting for the expert to make corrections!
Possible causes: 1. Faulty exhaust pressure sensor. 2. Incorrect startup logic (such as delayed detection of exhaust pressure). 3. Faulty safety valve
