Daily Shutdown 1. Display the "main screen" click "Stop" button to run the light off, the crew slowly shedding until shutdown. 2. Stop the condensate pump and cooling tower fan. 3. When the evaporator outlet temperature is higher than 15 ℃ after stopping the chilled water pump. Long-term shutdown as long downtime required to disconnect the main power supply, when the ambient temperature is below 5 ℃ cooling equipment maintenance, must be within the evaporator and condenser discharge clean water, to avoid freezing unit. 3. brass condenser fouling and more small diameter used refrigeration equipment, poor heat dissipation. Solution: Clean the condenser brass. 4. Too many refrigerant. Solution: excess refrigerant emissions. 5. The expansion valve opening is too large. Solution: appropriate to reduce the expansion valve opening degree, the compressor protection thermal relay valves (RESTET) pressed to identify the cause of cold storage refrigeration equipment, refrigeration Snow Dragon (certified), refrigeration equipment by the Dongguan City-long Refrigeration Electrical and Mechanical Equipment Engineering Co.
