The core component of an air-cooled ultra-low temperature freezer is the refrigeration system, which consists of a compressor, a condenser, an expansion valve, and an evaporator. When the compressor works, it will suck in the cryogenic gas and compress it into a high-temperature and high-pressure gas, and then release the heat into the external environment through the condenser, so as to obtain a high-pressure liquid. Next, the expansion valve expands the high-pressure liquid into a low-pressure liquid and sucks it into the compressor again for circulation. In this process, the cryogenic gases in the evaporator absorb the heat of the item and cool it down.
In addition to the refrigeration system, the air-cooled ultra-low temperature freezer is equipped with advanced control systems and safety protection devices. The control system can monitor and control the operating status of the equipment to ensure that the equipment is operating in the best condition. Safety protection devices can prevent equipment from being damaged or accidents under abnormal circumstances.
The advantages of air-cooled ultra-low temperature freezers are that they are efficient, reliable, safe and environmentally friendly. It uses advanced refrigeration technology to reduce the items to the required low temperature in a short period of time, while ensuring the quality and safety of the items. In addition, it is also energy-saving and environmentally friendly, which can reduce the impact on the environment.
In short, air-cooled ultra-low temperature freezer is an efficient, reliable, safe and environmentally friendly equipment, which is widely used in the freezing and transportation fields of food, medicine, chemical and other industries. The minimum temperature can reach minus 120 degrees.
