The development of cold storage can be traced back to the time when humans began to use natural ice and snow to preserve food. With the advancement of science and technology, cold storage technology has gradually evolved and has gone through several important stages. In ancient times, humans relied on natural ice and snow to preserve food. For example, ancient Chinese ice cellars used ice and snow collected in winter to store food, and ancient civilizations such as Egypt, Greece, and Rome also had similar technologies. Although this method is simple, it is limited by climatic conditions and storage time. In the early 19th century, mechanical refrigeration technology began to appear, marking a revolutionary advancement in cold storage technology. In 1805, American Oliver Evans designed the first vapor compression refrigerator. Subsequently, John Gorrie of Britain and Carl von Linde of Germany successfully manufactured practical refrigera […]

The refrigeration system is a general term for the equipment and pipelines through which the refrigerant flows, including compressors, condensers, throttling devices, evaporators, pipelines and auxiliary equipment. It is the main component system of air conditioning equipment, cooling and refrigeration equipment. The blockage failure of the refrigeration system has many forms such as ice blockage, dirty blockage and oil blockage. The unified fault characteristics of blockage are: the condenser is not hot when touched, the evaporator is not cold, the compressor operating current is smaller than normal, the pressure gauge is connected to the bypass charging valve, indicating negative pressure, the outdoor unit is running light, and there is no sound of liquid in the evaporator. Causes and fault phenomena of ice blockage The occurrence of ice blockage failure is mainly due to excessive moisture in the refrigeration system. With the continu […]
