Small cold storage with a refrigerator and condenser and other equipment together often called refrigeration units, refrigeration units have water-cooled units and air-cooled units. Small cold storage to air-cooled unit for the preferred form, it is simple, compact, easy to install, easy to operate, less ancillary equipment, etc., this refrigeration equipment is also easier to see. Refrigeration unit of the refrigeration machine is the heart of the refrigeration equipment, the common compression type refrigeration machine has open, semi-closed and fully closed type. The hermetic compressor is small, low noise, low power consumption, energy efficient. It is the first choice of small cold storage model, the air-cooled refrigeration unit composed of hermetic compressor-based, can be made into a split air conditioning like the form, hung on the wall mounted. Now on the market better hermetic refrigeration compressor, imported from developed countries or Sino-foreign joint venture refrigeration equipment product quality is more reliable, but the price is relatively high compared to the domestic machine to be more than 50% higher, more suitable for small towns and cities with refrigeration equipment for cold storage.
Freezer refers to a variety of equipment refrigeration, can be artificially controlled and maintain a stable low-temperature facilities. Refrigeration system, control devices, insulated warehouse, attached buildings are the basic components of the cold storage. Cold storage is used for the frozen processing and cold storage of food, medicine and machinery, which keeps the room at a certain low temperature through artificial refrigeration. Refrigeration system, cold storage refrigeration system mainly includes cold storage unit, which is the core of the cold storage, to ensure the supply of cold source in the cold storage room. Control device is the brain of the cold storage, it commands the refrigeration system to ensure the supply of cold. Cold storage cold storage warehouse, is the storage of fresh agricultural products, its role is to maintain the stability of the low-temperature environment, usually the thermal insulation is said to be heat preservation. Cold storage room good thermal insulation structure, can maximize the cold storage unit to maintain the cold volume manufactured in the cold storage less leakage to the outside, and conversely, is to minimize the cold storage outside the heat leakage to the cold storage, which is the main difference between the cold storage and general housing.
