Come fare il chiller industriale è allarmante quando acceso?
Analisi della causa dell'allarme di alta tensione:
& nbsp; & nbsp; & nbsp;The problem is very easy to solve if the cooling water is not turned on, but it is a frequent mistake. Solution: Please open the water valve.
& nbsp; & nbsp; & nbsp;The cooling water flow rate is too small or the temperature is too high. Solution: increase the flow of cooling water or reduce the temperature of the water (cooling water is allowed from 21 degrees to 38 degrees).
& nbsp; & nbsp; & nbsp;The condenser copper tube has much fouling, small diameter and poor heat dissipation. Solution: clean the condenser copper tube.
& nbsp; & nbsp; & nbsp;Too much refrigerant. Solution: appropriately reduce the opening degree of the expansion valve, press the compressor thermal relay protection switch (RESTET), and find out the reason.
Analisi della causa dell'allarme di bassa pressione:
& nbsp; & nbsp; & nbsp;Insufficient refrigerant. Solution: Pick up the leak, is there any leak point in the pipe joint? Replenish the refrigerant after repairing.
& nbsp; & nbsp; & nbsp;The filter is clogged. Solution: Remove and wash or replace the filter.
& nbsp; & nbsp; & nbsp;The expansion valve opening is too small. Solution: Properly reduce the opening degree of the expansion valve, and the high and low pressure protection will automatically reset after elimination.
