Unlike the ancient times when ice is difficult to be obtainable, nowadays with the help of ice making machines, people can make ice easily anytime and anywhere. And the types and shapes of ice is also very rich to choose from, including cube, flake, tube, block, plate and etc. Moreover, ice machines can also be divided into commercial ice machines and industrial ice machines. But no matter what kind of ice machine it is, the principle for making ice is much the same, which mainly consists of four key components:the compressor, the condenser, the evaporator and the throttle valve.
Compressor can be considered as the "heart" of the ice machine. It will firstly compress the low pressure refrigerant vapor into high pressure refrigerant vapor, and the vapor will then be delivered to the condenser.
The vapor will also go through some transformation in the condenser. Under the work of the condenser, the vapor will further be condensed into the high pressure liquid. There are mainly three types of condenser, which are air cooling, water cooling, and evaporative cooling.
Throttle valve here acts as the role of pressure release. When the high pressure liquid pass the throttle valve, it will then become the low pressure liquid.
After a series of transformation, here in the evaporator, the low pressure liquid will then conduct the heat exchange, and finally the ice is created.
In a nutshell, the content explained above is the basic working principle which is followed by most ice making machines.
