The invention relates to the field of refrigeration cold chain transportation, and discloses a comprehensive heat exchange uniform-temperature refrigeration fresh-keeping transportation device which comprises a carriage, a set of refrigeration main machine system, an enhanced convection heat exchange tail end and a ceiling radiation heat exchange tail end. The refrigeration main machine system comprises a conventional compressor, a condenser and an expansion valve. The enhanced convection heat exchange tail end comprises an air supply fan, a fan for mixing air in the compartment and two evaporators which are arranged in series front and back. The ceiling radiation heat exchange tail end comprises a heat exchange coil and a cold radiation ceiling. The two tail ends are connected with the refrigeration main machine system through respective valves and are used for switching working states. By means of different working characteristics of the two heat exchange tail ends, the problems that an existing cold storage cold chain transportation device is slow in pre-cooling, goods placement is limited, and temperature distribution in a compartment is uneven are solved, and the cold storage cold chain transportation device is suitable for the application fields of various cold storage cold chain transportation devices and the like.
本发明涉及冷藏冷链运输领域,公开了一种综合换热的均温冷藏保鲜运输装置,包括车厢、一套制冷主机系统、一个增强型对流换热末端和一个吊顶辐射换热末端。制冷主机系统包括常规的压缩机、冷凝器和膨胀阀。增强型对流换热末端包括一个送风用风机,一个混合车厢内空气的风机以及两个前后串联布置的蒸发器。吊顶辐射换热末端包括换热盘管和冷辐射吊顶。两个末端通过各自的阀门与制冷主机系统连接,并进行工作状态切换。本发明通过利用两个换热末端不同的工作特性解决了现有冷藏冷链运输装置预冷慢、货物摆放受限制、车厢内温度分布不均匀等问题,适用于各种冷藏冷链运输装置等应用领域。
