Refrigeration reason of star freezer

Star freezer is a kind of refrigeration equipment widely used in business and home. It can reduce the indoor temperature to below the temperature of the external environment, thus rapidly cooling down. The principle of star refrigerator refrigeration is to use compression refrigeration technology to absorb and release heat during compression and expansion by circulating refrigerant, so as to achieve refrigeration effect.

Star freezer is mainly composed of compressor, condenser, expansion valve and evaporator. When the star refrigerator is started, the compressor starts to operate, compressing the refrigerant into high-pressure gas. Then, the high-pressure gas enters the condenser and releases heat through heat exchange with the outside. At this time, the refrigerant has become a liquid, which is gradually decompressed by the expansion valve and flows into the evaporator. In the evaporator, the refrigerant expands into a gaseous state, exchanges heat with the surrounding air, and absorbs the heat of the indoor air, thus reducing the indoor temperature. Finally, the refrigerant is sucked into the compressor and recycled again to form a complete refrigeration process.

It should be noted that the refrigeration efficiency of star freezer is related to the indoor and outdoor temperature difference. If the temperature difference is small, the cooling effect will be weakened accordingly. In addition, long-term operation, poor heat dissipation, refrigerant leakage and other problems will also affect the refrigeration effect. Therefore, when using the star freezer, we should pay attention to regular maintenance, clean the condenser and evaporator in time, and ensure a good ventilation and heat dissipation environment to ensure its long-term stable and efficient operation.
