If there is oil leakage in the energy valve or if the spool valve comes loose, and the machine functions properly when under load but has difficulty doing so when under reduced load, then the cause is oil leakage in the energy valve. When the pressure of the chiller is high, insufficient oil supply from the energy valve makes it difficult to reduce the load. The owner can try to see whether the energy valve can still enable load reduction after the chiller stops operating and the pressure drops. The solution is to replace the rubber ring inside the energy valve or replace the energy valve itself. Could the original poster describe the phenomenon in more detail?
The temperature is required to be kept at 0°C, but it has already dropped to -3°C yet the energy level still doesn’t decrease automatically. It’s possible to reduce the number of plants planted manually – what’s going on?
Is there a problem with the control system of the circuit board?
