What are the reasons for the working process of the ice machine and the excessive sound of the compressor?

After the compressor of the ice machine is in normal operation, it will evaporate in the evaporator at a low temperature of -10 to -18 degrees through the suction-compression-exhaust-condensation-throttling process, and the frozen water will be vaporized in the low-temperature water It condenses into an ice layer on the surface of the evaporator. The following editor will introduce to you the working process of the ice machine and what causes the compressor to make too much noise? content, welcome to read!

The working process of the ice machine:

1. After the ice machine is powered on, the switch indicator light of the controller box is on, the water pump and the drain solenoid valve need to be powered on for 45 seconds, and the drain time is set to 45 seconds. The residual water in the tank needs to be removed to ensure the cleanliness of the entire ice making water Spend. The hot gas valve needs to be energized throughout the unit draining process.

2. Turn on the water inlet solenoid valve for the entire ice making and harvesting process. 5 seconds after the compressor is started, the hot gas valve is closed, and the compressor starts the water pump after 30 seconds of pre-cooling the ice chamber (evaporator). When the water in the sink touches the water level detector for 3 seconds in a row (when the water level detector is in contact with water, the water level WATER indicator light of the controller is on), close the water inlet valve for 6 minutes in a row.

3. Under the action of the water pump and the water separator, the water flows through every small grid of the refrigerator and is frozen. As the water level of the ice cubes drops, the water level WATER indicator goes out. At this time, stop replenishing water to the water level until the detector is in contact with water for 3 seconds, and stop enough water to make ice.

What are the reasons for the excessive sound of the compressor?

1. The pressure of the refrigerant in the ice machine is too high or too low, which makes the compressor unable to work normally.

2. The gas or sundries in the refrigerant pipes cause deformation of the equipment pipes.

3. The fan of the air-cooled ice machine is broken, and the speed is relatively slow, resulting in poor heat dissipation, so the ice making speed is relatively slow and the time is relatively long, causing the compressor to burn out.

After the ice machine has been used for a period of time, it is necessary to open the water inlet pipe and clean the filter screen of the water inlet valve to avoid excessive sand and mud impurities in the water, which will reduce the water intake and prevent the equipment from making ice normally. After each ice maker makes ice, the excess water in the water tank is discharged by cooling, which can achieve the purpose of cleaning and reduce the amount of scale in the evaporator and water circulation.
