The importance of supermarkets for public life is self-evident, and as the end of the cold chain logistics of agricultural and sideline products, supermarkets have high quality requirements for product quality in distribution and retail. The freezing and refrigeration equipment in supermarkets plays a significant role in food preservation, playing an important role in meeting the growing needs of the people for a better life.

Cold chain logistics generally refers to a systematic project in which refrigerated and frozen food products are always in a specified low-temperature environment throughout the production, storage, transportation, distribution, and various stages to the consumer end, in order to ensure food quality and reduce food loss. It was established with the progress of science and technology and the development of refrigeration technology. It is a low-temperature logistics and storage process based on refrigeration technology and using refrigeration technology as a means. The rapid development of China's agricultural cold chain logistics industry requires the country to formulate and implement scientific and effective macro policies.

Food refrigeration is a specialized technology that uses low-temperature technology to lower the temperature of food and maintain it in a low-temperature state to prevent food spoilage and prolong its shelf life. Low temperature preservation can be used for the storage of fresh food materials, as well as widely used in food processing and semi-finished product storage. With the gradual improvement of living standards, people are paying more and more attention to the reasonable intake of nutrients, and the requirements for food preservation are also gradually increasing.

In industrial production, refrigeration equipment can accurately achieve certain cooling processes or perform air conditioning, and is widely used in fields such as chemical, pharmaceutical, medical, and electronics. In the pharmaceutical and medical field, due to the particularity of the industry, high requirements are placed on the environmental temperature, humidity, and cleanliness during the production and storage of pharmaceutical products, which also puts higher demands on related refrigeration equipment.

Star rated hotels and restaurants will be equipped with dedicated cold storage to store food or food ingredients. Hotel catering cold storage is often designed as dual temperature storage (or even multi temperature storage) to meet the optimal storage temperature requirements for different foods: Cold storage is mainly used for storing fruits and vegetables; The freezer is mainly used for storing seafood, frozen meat, etc

Industrial chillers are widely used in various industrial refrigeration processes such as plastics, electroplating, electronics, chemicals, pharmaceuticals, printing, food processing, etc., which require the use of chilled water. They can also provide comfortable air conditioning for activity spaces such as villas, restaurants, hotels, offices, schools, factories, etc. As one of the solutions for ammonia to fluorine conversion, low-temperature chillers are a recommended solution.
