The core is equipped with an efficient on-board dedicated refrigeration unit, supporting the optional installation of domestically produced or imported units with equivalent power. The refrigeration temperature can flexibly cover all scenarios from -25 ℃ to+15 ℃, which can complete the freezing transportation of meat, seafood and other goods, as well as the preservation and refrigeration of fruits, vegetables and dairy products. It can also adapt to transportation scenarios with strict temperature requirements such as vaccines and drugs, in line with GSP certification requirements. At the same time, it can meet the transportation needs of goods such as flowers that require specific constant temperature environments, effectively extending the shelf life. The refrigeration system operates stably, with a fast cooling rate that can quickly reach the set temperature and maintain a constant temperature. Temperature fluctuations are controlled within a reasonable range, combined with excellent insulation performance to avoid deterioration of goods due to temperature fluctuations during short and medium distance transportation. At the same time, the refrigeration unit also takes into account energy conservation and environmental protection, reducing energy consumption and environmental pollution. The refrigerated compartment body adopts a fully sealed sandwich composite structure, strictly following the professional thermal insulation process, and the exterior is made of high-quality anti-corrosion glass fiber reinforced plastic, which is beautiful, durable, and anti-aging. The internal skeleton is made of wood wrapped galvanized pipes and has been subjected to bridge breaking and thermal insulation treatment. The middle is filled with a high-density polyurethane thermal insulation layer, which has low thermal conductivity and excellent thermal insulation performance. It can effectively block the external temperature conduction, reduce cooling energy consumption, ensure the long-term stability of the temperature in the compartment, and adapt to the continuous thermal insulation needs of short and medium distance transportation. The bottom of the cabin is equipped with aluminum alloy anti slip patterned plates, which are easy to clean and anti slip and wear-resistant. Aluminum guide rail ventilation slots can be optionally installed according to needs to improve the efficiency of cold air circulation; The exterior is wrapped with aluminum alloy profiles and stainless steel corners. The rear door frame and locking components are made of stainless steel material, paired with tight rubber sealing strips to enhance sealing performance and prevent air conditioning leakage. The top of the carriage is closed and cannot be opened, further improving the insulation effect.
