With the rapid development of China's economy, the refrigeration equipment has entered various fields supermarkets, commercial, agricultural and industrial, closely linked with our lives. Due to the rapid development of refrigeration, the user faces many of the manufacturers on the market and a wide variety of, often do not know how to choose, especially high demand, when investing more, even more difficult choice. Here we introduce some common sense and the purchase method of cold storage, cold storage might be helpful for you to buy. ? The use of cold storage and classification? Cold is a way for artificial refrigeration temperature reaches a predetermined temperature within a fixed space for storing items in the building. Cold storage can be widely used in food plants, dairies, pharmaceutical plants, chemical plants, fruit and vegetable warehouse, eggs warehouses, hotels, restaurants, supermarkets, hospitals, blood banks, troops, laboratories and the like. Cold storage is mainly used for food, dairy products, meat, fish, poultry, fruits and vegetables, drinks, flowers, plants, tea, medicines, chemicals, electronic instrumentation and other constant temperature storage. Cold storage can be divided into different types according to various characteristics. ? First, according to the classification scale cold storage capacity. Currently, cold storage capacity division nor unity, generally divided into large, medium and small. Large cold storage refrigeration capacity of 10,000 tons or more; medium-sized cold storage refrigeration capacity in 1000 to 10,000 tons; small refrigerator refrigeration capacity of 1000 tons. Second, according to the design temperature refrigeration classification. It can be divided into high, medium temperature, low temperature and cryogenic refrigerator four categories. ? General design temperature refrigerated cold temperature -2 ℃ ~ + 8 ℃; temperature cold storage refrigeration design temperature at -10 ℃ ~ -23 ℃; cold storage temperature is generally -23 ℃ ~ -30 ℃; ultra-low temperature frozen storage temperature General of -30 ℃ ~ -80 ℃. ? Third, according to the library structure into the categories. ? First, cold storage construction. This is more of a build cold storage, it can be built single or multiple layers. The main building is generally reinforced concrete frame structure or masonry structure. Cold storage building envelope is a heavy civil body structure, large thermal inertia, the outdoor air temperature outside the diurnal fluctuation and envelope surface by the diurnal temperature fluctuations caused by solar radiation, greater attenuation in the envelope, the envelope so the inner surface temperature fluctuations on small and easy storage temperature will stabilize. Followed by a combination of cold plate. This cold storage as a single form, the library board is lightweight prefabricated steel frame insulation board assembly structure, its load-bearing member to use more thin-walled steel production. Within the library board, the outer panels are color steel plate, the library board's core material is a rigid polyurethane foam or polystyrene foam board adhesive. Because in addition to the ground, all components are according to uniform standards in the professional factory pre-sets, assembled at the site, so construction progress fast, short construction period. ? Once again, cold soil. It is also known as the cold soil cave, cave mostly arched structure, a single-hole style, but also form a continuous arch. Generally brick masonry, and some loess cover layer thickness as insulation. Casing used for low temperature cold storage, the foundation should cave in on easy gravel layer of frost or bedrock. Because of its local conditions, local materials, the construction is simple, low cost, durable, etc., to obtain greater development in Northwest China. ? There is a cave cold. Usually built relatively hard stone, overall good rock within the inside lining or cave generally do spray anchor handling, rock cave covering thickness of not less than 20 meters.
