In the context of the booming cold chain logistics today, the performance of equipment for vehicle refrigeration transport unit is crucial, especially the refrigeration stability in high temperature and high humidity environment is directly related to the quality and safety of goods.
First of all, the design of the refrigeration system of equipment for vehicle refrigeration transport unit is a key factor. The use of efficient compressor technology, such as scroll compressor, can continuously and stably provide strong refrigeration power in high temperature environment. Its special structural design makes the suction, compression and exhaust processes more efficient, and can quickly reduce the temperature in the car even if the outside temperature rises. At the same time, with a large area condenser, the heat sink material of the condenser is made of aluminum alloy with high thermal conductivity, which can quickly dissipate heat in a high humidity environment, ensuring the smooth progress of the refrigeration cycle and avoiding the decrease in refrigeration efficiency due to poor heat dissipation.
Secondly, the temperature control system plays a role in precise regulation. Advanced sensor technology can monitor the temperature and humidity changes in the car in real time and feedback to the control system. The control system automatically adjusts the start and stop of the compressor, the speed of the fan and other parameters according to the preset temperature range. For example, when the temperature is detected to be rising in a high temperature and high humidity environment, the refrigeration capacity is quickly increased, and the frequency conversion technology is used to make the compressor run at high speed to accurately maintain the required temperature of the refrigerated environment and prevent the goods from being damaged by temperature fluctuations.
In addition, the quality of thermal insulation materials has a significant impact. The compartment wall adopts multi-layer composite thermal insulation materials, such as polyurethane foam sandwich panels, whose internal micro-bubble structure can effectively block heat transfer and reduce the interference of external high temperature on the temperature in the compartment. In a high humidity environment, the moisture-proof performance of the material is also critical to prevent water vapor from invading and reducing the insulation effect, and ensure the sealing and stability of the refrigerated space.
The defrosting system should not be ignored either. Under high temperature and high humidity conditions, the surface of the evaporator is very easy to frost. If it is not handled in time, it will hinder heat exchange and reduce refrigeration efficiency. Therefore, it is equipped with an intelligent defrosting system, which can start the heating element or hot gas bypass defrosting in time through comprehensive judgment of multiple parameters such as time, temperature, and pressure, to ensure that the evaporator is always in good working condition and maintain stable refrigeration.
In addition, daily maintenance of equipment for vehicle refrigeration transport unit is essential. Regularly check the amount and purity of the refrigerant. In high temperature environments, insufficient refrigerant will seriously affect the refrigeration effect; clean the dust and dirt on the surface of the condenser and evaporator to ensure heat exchange efficiency; check the connection and insulation of the electrical system to prevent short circuit failures caused by high temperature and high humidity, and ensure the reliable operation of the unit.
From the long-term operation data, the equipment for vehicle refrigeration transport unit, which has been optimized and strictly maintained, can stably control the temperature of the carriage within the specified refrigeration range in high temperature and high humidity environments, such as the southern coastal areas in summer, effectively ensuring the freshness and quality of perishable goods, and providing solid protection for cold chain logistics.
