Small refrigerator is generally divided into indoor and outdoor type, with large cold storage units the biggest difference is that the refrigeration equipment, such as the small cold storage refrigeration equipment is mostly used for general air-cooled units, and large cold storage with water-cooled units mainly. To cold storage temperature setting to distinguish small cold storage is mainly divided into three categories: cold storage, cold storage, low temperature cold storage. Cold storage temperature at 0 ℃ below small cold storage, the installation must be paved on the ground channel is used to keep the bottom overhead storage, ventilation; above this temperature cold storage can directly contact with the ground.
　　Many want to build refrigeratory businesses and individuals are hoping to be a lower price to build, which ignores the cold storage equipment configuration matching result is reasonable, cold storage projects after the completion of installation of refrigeration effect is not ideal. The reasonable configuration of cold storage project in the refrigeration equipment is very necessary, although a certain increase in the investment, but in the long-term use can effectively reduce the energy consumption and maintenance cost.
　　Refrigeration unit is a cold heart, small refrigerator uses basically is totally closed compressor units, import and production joint venture refrigeration equipment quality indeed superior to domestic equipment, but the high price. Because of many small refrigeratory lack of professional maintenance staff, maintenance cost and recommendations from the enterprise in the compressor selection of imported products. Current common market refrigeration unit for Pitzer and eureka.
　　In addition to remind users of various cold storage, daily stock volume have certain restrictions, general every purchase amount shall not exceed the effective volume of the 8-10%, if more than this value will affect the cold storage refrigeration effect, effective volume is generally around 70% of total storage space; if the cold storage is used for storage of vegetables and other agricultural products, general also need to reduce 20% of the volume of purchase.
