Advantages of building small refrigerators in rural areas:
It is most suitable to build small cold storage of 10-20 tons in rural areas. This kind of small cold storage unit has the advantages of small capacity, easy control, convenient in and out of the warehouse. A product is easy to be fully stored, rapid cooling, stable temperature, low power consumption, high degree of automation, and is as easy to manage as household air conditioner and refrigerator. Several such small refrigerators are built together to form a group of small refrigerators with a total capacity of hundreds of tons and thousands of tons. Its total investment is similar to that of medium and large refrigerators of the same scale. But it can keep more products and varieties fresh. According to the different requirements of keeping fresh temperature, it can be controlled separately, which is not easy for large capacity cold storage. In a word, the flexibility, operability, automation, energy-saving effect, and operation effect of small-scale refrigerators in rural areas are much better than those of medium-sized and large-scale refrigerators.
Refrigeration equipment for small refrigerators:
Refrigeration equipment is the heart of cold storage, which is very important. The most critical condition for the performance of cold storage is the condensing unit for cold room. There are two kinds of refrigerants: ammonia machine and fluorine machine. Some fluorine machines are general models of various refrigerants. Advanced fluorine machines use R22 and other new refrigerants which have little impact on the environment. Fluorine machine is generally small in size, low in noise, safe and reliable, high in automation and wide in the application, which is suitable for small rural cold storage. The combination of refrigerator, condensing unit for cold room and other equipment is often called a refrigeration unit, which is divided into the water-cooled unit and air-cooled unit. The common compression chillers are divided into open type, semi-closed type, and fully closed type. The hermetic compressor has the advantages of small volume, low noise, low power consumption, high efficiency, and energy-saving. It is the first choice model of small rural cold storage. The air-cooled refrigeration unit mainly composed of totally enclosed compressors can be made in the form of a split air conditioner and hung on the wall. At present, the quality of products imported from developed countries or jointly invested by Chinese and foreign companies is more reliable, but the price is more than 50% higher than that of domestic compressors.
