The Ice Cubes Made in The Refrigerator At Home Melt Quickly, But The Ice Cubes in The Cold Drink Shop Melt Very Slowly. Why?

The ice cubes made in the refrigerator at home melt quickly, but the ice cubes in the cold drink shop melt very slowly. Why?

No matter the season, a drink with ice is always refreshing and a well-being booster, so why do ice cubes used in the freezer at home melt faster than those at the soda store? In fact, it can be understood as the difference between a commercial ice machine and a home ice machine. Let me share some dry goods that many people don’t know!

A household refrigerator is a relatively common household appliance. The main function of the refrigerator is refrigeration. The refrigeration system of the refrigerator is mainly composed of an evaporator, a compressor, a condenser and a capillary tube to form a closed cycle system. Refrigeration of the refrigerator is a process of energy conversion. The compressor of the refrigerator will come from the low temperature, The low-pressure steam is compressed to become high-temperature and high-pressure steam and then enters the condenser. In the condenser, the refrigerant continuously releases heat to the surrounding space and condenses into a high-pressure liquid. The high-pressure liquid becomes a low-temperature and low-pressure liquid that flows into evaporation In the evaporator, the refrigerant evaporates to absorb the heat in the refrigerator, and the low-pressure liquid is vaporized into gas, so that the temperature in the small refrigeration system of the refrigerator freezer is lowered, and the low-pressure steam after absorbing the heat of vaporization returns to the compressor, and then circulates. To achieve the purpose of refrigeration, so that the refrigeration effect of the refrigerator is realized. Since the refrigeration is a single-system refrigeration, the refrigerator and freezer share an evaporator, and when the refrigerator is cooled, the freezer will be forced to cool. At this time, the temperature of the freezer not only has a large temperature difference, but also depends on the cooling of the freezer. The temperature effect of such a freezer is definitely not good. Not only is the ice making slow, but there will also be ice cracks on the surface. Because it is an ordinary room temperature water freezer Ice cubes, the inside is opaque, there are micro-bubbles inside, and the inside is not frozen tightly, so it is easy to melt.

The ice cubes in the cold drink shop come from the commercial ice machine. The ice making principle of the commercial ice machine is that through the water inlet valve, the water automatically enters a water storage tank, and then pumps the water to the shunt pipe, and the shunt pipe flows the water evenly to the receiver. On the evaporator after the cooling of the low-temperature liquid refrigerant. The water is cooled to the freezing point, and the water cooled to the freezing point will solidify into ice, and the water that has not been frozen by the evaporator flows into the water storage tank, and the circulation is restarted through the water pump. When the ice cube reaches the required thickness, it enters the In the deicing state, the high-pressure hot gas discharged from the compressor is diverted to the evaporator through the reversing valve to replace the low-temperature liquid refrigerant, so that a layer of water film is formed between the ice cube and the evaporator, and this water film makes the ice The ice cubes leave the evaporator, and the ice cubes fall freely into the ice storage tank below by gravity. The ice cubes produced in this way have been degassed and are more like a perfect crystal. There is no air inside the ice cubes, the density is low, and the ice cubes are not easy to melt.
