Drug cold install the cool production design Zi Yun no-frost refrigerator brand frozen refrigeration mode, configure the brand compressor and refrigeration parts, the use of automatic defrosting, control microcomputer intelligent control. Refrigeration system using green refrigerant, the 21st century belongs to the international advanced refrigeration technology. Material novel: Library body with rigid polyurethane or polystyrene foam insulated sandwich panels with high-pressure foaming process once infusion molding, can be made of various lengths, specifications to meet the different requirements of customers. Its characteristics are: thermal insulation performance, light weight, high strength, corrosion resistance, aging resistance, beautiful appearance. Cold storage panel types are: color steel, salinization steel, stainless steel, embossed aluminum. Easy assembly and disassembly: Zi Yun cold siding mold all unified by the internal bump slot connector for easy assembly and disassembly handling, installation time is short, medium and small refrigerator 2-5 days to delivery, storage body can be freely combined according to user needs, separated or increase, decrease. Widely applicable: cold storage temperatures are + 15 ℃ ~ + 8 ℃, + 8 ℃ ~ + 2 ℃ and + 5 ℃ ~ -5 ℃. And to achieve a library dual temperature or temperature, to meet the different needs of users. Between large and small refrigerator to cool for 1 to buy into the library need to be refrigerated or freeze after pre-cooling (refers to the use of secondary freeze process) of room temperature food, cooling or pre-cooling. Processing cycle is generally 12 ~ 24h, the product after pre-cooling temperature is generally 4 ℃. 2. The need for inter-freeze frozen food at room temperature or by rapid cooling down to -15 ℃ state or 18 ℃, the processing cycle is generally 24h. 3. cooling substance known as inter-temperature refrigerated cold room, mainly used for storage of eggs, fruits, vegetables and other foods. Frozen Food Storage Room 4. Also known as cold storage rooms, the main storage via freeze processed foods, such as frozen meat, frozen fruits and vegetables, frozen fish and so on. 5. freezer storage room, also known as ice, for the storage of artificial ice, the need to solve the shortage of ice and ice season capability contradictions. Temperature and relative humidity between cold, should be based on all kinds of food cold or frozen process requirements to determine the general election according to Table 1-1-1
