Non-Independent Split Unit Refrigeration Equipment：For Vehicle Refrigeration Transport Unit
Publish Time: 2024-08-15
In the field of cold chain logistics, vehicle-mounted refrigerated transport units are key equipment to ensure that goods remain within a specific temperature range during transportation. Among them, non-independent split refrigeration equipment has been widely used in small and medium-sized refrigerated transport vehicles due to its unique advantages. This article will introduce in detail the working principle, characteristics, application and maintenance of non-independent split refrigeration equipment vehicle-mounted refrigerated transport units.1. Working principleNon-independent split refrigeration equipment vehicle-mounted refrigerated transport units, as the name suggests, refer to refrigeration units that do not have independent power sources. This type of unit is connected to the engine of the refrigerated truck and uses the power of the engine to drive the compressor to work, thereby achieving a refrigeration effect. Its working principle mainly includes four processes: compression, condensation, expansion and evaporation. Through the cycle of these four processes, the heat in the car is continuously transferred to the external environment, thereby achieving the purpose of cooling and preservation.2. FeaturesPrice advantage: Compared with independent refrigeration units, non-independent split refrigeration equipment has a more obvious price advantage. Since the cost of independent power sources (such as generators or motors) is eliminated, the cost of the entire unit is lower and more suitable for the needs of small and medium-sized refrigerated transport vehicles.Simple structure: The structure of non-independent split refrigeration equipment is relatively simple, which reduces the complexity of maintenance and upkeep. Its split structure (such as front-mounted, top-mounted or bottom-mounted condenser) is easy to install and repair, and improves the efficiency of use.Strong dependence: However, a significant disadvantage of non-independent split refrigeration equipment is that it is too dependent on the engine of the refrigerated truck. Once the engine is turned off or fails, the refrigeration unit will not work properly, which may cause damage to the goods in the compartment.Environmental protection and energy saving: With the advancement of technology, modern non-independent split refrigeration equipment has also been significantly improved in environmental protection and energy saving. The use of high-efficiency compressors and environmentally friendly refrigerants can reduce energy consumption and environmental pollution while ensuring the refrigeration effect.3. ApplicationNon-independent split refrigeration equipment on-board refrigerated transport units are widely used in the transportation of various goods that require low-temperature preservation, such as fresh food, pharmaceuticals, chemicals, etc. For refrigerated trucks with a body length of less than 6 meters, non-independent split refrigeration equipment is a more ideal choice. Such vehicles are usually used for short-distance or point-to-point distribution within the city, which can meet the basic needs of goods for temperature control.4. MaintenanceIn order to ensure the normal operation and extend the service life of the non-independent split refrigeration equipment vehicle-mounted refrigerated transport unit, the following are some maintenance suggestions:Regular inspection: Regularly inspect the unit, including the cleaning and tightening of components such as the compressor, condenser, and evaporator. Check the pressure and leakage of the refrigerant to ensure the normal operation of the system.Maintain the engine: Since the non-independent split refrigeration equipment relies on the engine of the refrigerated truck to work, maintaining the engine is essential for the normal operation of the unit. Maintenance measures such as regular oil replacement and air filter cleaning can improve the working efficiency and reliability of the engine.Avoid frequent switching on and off: Frequent switching on and off will cause unnecessary wear and load on the compressor and other components of the unit. Try to keep the unit running continuously during transportation to reduce the number of starts and stops.Reasonable use: Reasonably set the refrigeration temperature and working time of the unit according to the type and temperature requirements of the goods. Avoid excessive cooling or long-term low-temperature operation to reduce energy consumption and unit wear.In summary, the non-independent split refrigeration equipment vehicle-mounted refrigerated transport unit has occupied a certain market share in the field of cold chain logistics with its price advantage and simple structure. However, in practical applications, attention should still be paid to its shortcomings such as strong dependence, and effective measures should be taken for maintenance to ensure the normal operation of the unit and extend its service life.
