How the ice maker circulates and freezes?

The principle of ice maker circulatory freezing is achieved through the phase change process of the refrigerant in the circulation system. The specific principles are as follows

1. The circulation system of the ice maker contains a refrigerant, usually ammonia or Freon. The refrigerant absorbs heat under high pressure and then releases heat under low pressure.

2. The compressor in the circulation system sucks the refrigerant into the condenser to increase its pressure and temperature. The high-temperature and high-pressure refrigerant enters the condenser at this time.

3. Through heat exchange in the condenser, the refrigerant releases heat, and the temperature and pressure drop. At this time, the refrigerant becomes a high-pressure liquid.

4. The high-pressure liquid refrigerant enters the evaporator through the expansion valve, and there is low-temperature and low-pressure air inside the evaporator.

In the evaporator, the refrigerant absorbs heat and evaporates, while cooling the air in the evaporator. The temperature and pressure of the refrigerant drop accordingly.

6. The cooled air is blown out of the ice maker, and when it comes into contact with water, the temperature of the water also drops, and finally freezes.

7. The refrigerant that passes through the evaporator becomes a low-pressure gas and enters the compressor again, and the cycle repeats.

Through continuous circulation, the refrigerant in the ice maker realizes the cyclic process of absorbing heat to evaporate and releasing heat to condense, thereby achieving the purpose of cooling and freezing.
