Cold storage type and selection of rural origin construction

      cold storage type and country of origin of our choice of cold storage type many, the lack of uniform standards of classification. According to the type and origin of commonly used simple introduction is as follows:  
(1) according to the storage size classification of large cold storage, medium and small points. Commercial, medium-sized library general information sense, capacity is too large. According to the current frozen cold storage in our country are relatively small and the characteristics of the masses used to name, can put the capacity of 1000 tons more than the library called large base, 1000 tons, 100 tons more than the following library called medium base, 100 tons of library called small library. The most suitable for the origin country to build 10 tons to 100 tons of small-scale cold storage.
(2) according to refrigerant refrigerator use can be divided into ammonia refrigeration ammonia hangar and fluoride machine refrigeration fluorine hangar, rural origin to build a small cold storage can choose a high degree of automation of the fluorine hangar.
(3) temperature in cold storage was built at low temperature and high temperature of library library library, preservation of fruits and vegetables is generally high temperature storage, the lowest temperature 2 C. Aquatic, carnivorous fresh library is the library at low temperature, temperature - 18 DEG c..  
(4) in cold storage in the form of exhaust pipe cold distributor of cold storage and cold storage cold air machine. Fruits and vegetables preservation generally with the cooler cold storage, commonly known as cold library.  
(5) according to the warehouse building mode is divided into cold storage construction, assembly of cold storage and civil assembly composite type cold storage. Cold storage construction is generally sandwich wall insulation structure, covers an area of large, long construction period, the early cold storage is this way. Fabricated cold storage is prefabricated insulation board assembly of the warehouse, the construction period is short, removable, but larger investments. Civil assembly composite type cold storage warehouse, the bearing and a peripheral structure is civil form, spray polyurethane foam insulation structure is or polystyrene foam board assembly form. The civil assembly composite type cold storage of polystyrene foam board insulation is the most economic and suitable, is the preferred form of storage of origin.
