Applying the Phase Change Materials (PCMs) in the refrigerated truck is a reliable method of cold storage because they have high latent heat of melting and can have very low melting points. The PCM absorbs the cooling load of the container during its melting and ensures a constant temperature. In this study, the temperature variations inside the box of a 6-ton refrigerated truck are presented for three types of PCMs. The tested materials were Sub-Zero Eutectic PCMs named by E-26, E-29, and E-32. The tests were conducted for a constant path of 466 km length. Each PCM was studied at different truck speeds of 80–110 km h⁻¹. The overall heat transfer coefficient was obtained from the measurement results in different situations. The results showed that the speed of the truck increases the overall heat transfer coefficient. The minimum and maximum overall heat transfer coefficients of 0.27 and 0.33 W m⁻² K⁻¹ were obtained for E-26 and E-29 PCMs at the truck speeds of 81 and 110 km h⁻¹, respectively. Among the studied PCMs, the type E-26 gave the maximum melting time of 17200s at the truck speed of 81 km h⁻¹. For a stationary truck, E-26 PCM had the maximum melting time of 18,400 s. The maximum traveling distance of 491 km was obtained when PCM E-26 was used at a truck speed of 110 km h⁻¹.

在冷藏车中使用相变材料（PCM）是一种可靠的冷藏方法，因为它们具有较高的熔化潜热，并且熔点可能非常低。PCM吸收了融化过程中容器的冷却负荷，并确保了恒定的温度。在这项研究中，针对三种类型的PCM，介绍了6吨冷藏卡车箱内的温度变化。被测试的材料是由E-26，E-29和E-32命名的次零共晶PCM。测试是针对466公里长的恒定路径进行的。在不同的卡车速度80–110 km h ^-1下研究了每个PCM。从不同情况下的测量结果可以得出总的传热系数。结果表明，卡车的速度增加了总的传热系数。对于E-26和E-29 PCM，在卡车速度分别为81和110 km h ^-1时，最小和最大总传热系数分别为0.27和0.33 W m ^-2 K ^-1。在所研究的PCM中，E-26型在卡车速度为81 km h ^-1时的最大熔化时间为17200s 。对于固定卡车，E-26 PCM的最大熔化时间为18400 s。当以110 km h ^-1的卡车速度使用PCM E-26时，最大行驶距离为491 km 。
