During car travel, the performance of the car refrigerator is directly related to the freshness and safety of food and drinks. As the core component of the vehicle refrigerator, the refrigeration system and technology have a crucial impact on its performance.
Refrigeration system selection
First of all, the choice of refrigeration system is crucial to the performance of the car refrigerator. At present, the main vehicle refrigerator refrigeration systems include compression refrigeration and absorption refrigeration. The compression refrigeration system utilizes the cyclic process of compression, condensation, expansion and evaporation of the refrigerant to achieve the refrigeration effect. It has the characteristics of fast refrigeration speed and high refrigeration efficiency, and is suitable for most car refrigerators. The absorption refrigeration system uses the absorption and release of refrigerant to achieve refrigeration. Although the refrigeration efficiency is relatively low, it has advantages in environments where there is no power supply or where silence is required.
Refrigeration efficiency and speed
The performance of the refrigeration system directly affects the cooling efficiency and speed of the vehicle refrigerator. Compression refrigeration systems usually have higher refrigeration efficiency and speed, and can reduce the temperature inside the box to the set value in a short period of time. They are suitable for long-distance travel or scenarios that require frequent access to food. The absorption refrigeration system has a slower cooling speed and is suitable for silent environments or long-term parking situations.
Temperature control accuracy
In addition, the refrigeration system also has an important impact on the temperature control accuracy of the vehicle refrigerator. Good temperature control ensures that food and drinks inside the box stay fresh at the right temperature. Compression refrigeration systems usually have more precise temperature control capabilities and can stably maintain the temperature inside the box within a set temperature range. The temperature control accuracy of the absorption refrigeration system is relatively low, and there may be temperature fluctuations.
Energy consumption and efficiency
The energy consumption and efficiency of the refrigeration system are also important considerations in the performance of the vehicle refrigerator. Compression refrigeration systems can usually achieve a higher energy efficiency ratio, that is, they can provide better refrigeration effects under the same energy consumption. The energy efficiency ratio of the absorption refrigeration system is relatively low and may require more energy to maintain the cooling effect. Therefore, when selecting a vehicle refrigerator, its energy consumption and cooling effect need to be considered comprehensively.
