The energy storage type refrigerating system comprises a heat regenerator and a phase change cold storage unit, the heat regenerator is provided with a low-pressure channel and a high-pressure channel which can achieve heat exchange, and an outlet of the high-pressure channel is divided into two branches; wherein one branch exchanges heat with the phase change cold storage unit through a throttling valve and then enters a low-pressure channel of the heat regenerator, the other branch enters a generator through a second control valve and a first circulating pump, and high-temperature and high-pressure refrigerant steam generated by the generator serves as working fluid and enters a first ejector and a second ejector correspondingly; the first ejector ejects refrigerant superheated gas from a low-pressure channel outlet of the heat regenerator, an outlet of the first ejector is connected with an ejection fluid inlet of the second ejector, and an outlet of the second ejector is connected with a high-pressure channel inlet of the heat regenerator through the condenser. According to the device, photovoltaic and vehicle tail gas waste heat complementation is adopted, consumption of petrochemical energy is reduced, and the distribution range of the cold chain vehicle is widened.
本发明公开一种蓄能式制冷系统、冷链运输车及其制冷方法,包括回热器和相变蓄冷单元,所述回热器具有能够实现热交换的低压通道和高压通道,所述高压通道的出口分为两个支路,其中一个支路经过节流阀与所述相变蓄冷单元进行热交换后进入回热器的低压通道,另一支路经过第二控制阀和第一循环泵进入发生器,发生器产生高温高压的制冷剂蒸汽作为工作流体分别进入第一喷射器和第二喷射器,第一喷射器引射来自回热器的低压通道出口的制冷剂过热气体,第一喷射器的出口与第二喷射器的引射流体入口相连,第二喷射器的出口通过冷凝器与所述回热器的高压通道入口相连。本装置采用光伏与车辆尾气余热互补,减少了石化能源的消耗,扩大了冷链车的配送范围。
