A combined refrigeration cold chain transport vehicle

Abstract

The invention belongs to the field of cold chain transportation, and discloses a combined refrigeration cold chain transport vehicle comprising a vehicle fueled by LNG, a tank arranged on the vehicleand liquid inert gas storage tanks which are acrried. A heat exchange refrigeration system that uses liquid LNG and liquid inert gases as a cold source to exchange heat with the internal space of thetank to realize refrigeration. By combination usage of liquid inert gas and liquid LNG cooling capacities, the cold chain transport vehicle can reduce the volumes of liquid inert gas storage tanks, reduce the vehicle volume, increase the logistics distance, improve the energy utilization, and avoid problems of large fluctuations in refrigeration, a short logistics distance, and excessive equipmentvolumes due to exclusive usage of liquid inert gases and LNG as a cold source.

Description

technical field [0001] The invention relates to the field of cold chain transportation, in particular to a combined refrigeration cold chain transportation vehicle. Background technique [0002] The applicant Huaxing Longhui (Beijing) Technology and Trade Co., Ltd. filed an invention patent application CN201811126598.3 in 2018, disclosing an intelligent multifunctional gas molecule cold chain vehicle. On the front of the wall-mounted vehicle, the container insulation box is installed on the rear of the wall-mounted cold chain vehicle, and the cooling source is installed between the container insulation box and the front of the wall-mounted vehicle; the condenser unit is installed outside the container insulation box, and the cooling source is connected through pipelines To the container insulated box, the gas molecule balance component is installed on the top of the container insulated box; the condenser unit provides refrigerant for the container insulated box; the cooling ...

AI Technical Summary

Problems solved by technology

[0010] The disadvantage of the above technology is that if an independent cold source is used, then the vehicle needs to mount two 450L liquid nitrogen tanks in a journey of 2000-3000km to be barely enough, as shown in the attachment of CN201811126598.3 figure 1 As shown, it mounts four 450L liquid nitrogen tanks

[0011] If LNG is used for cooling alone, the gas source will not be stable as the vehicle is running. For example, the vehicle does not need LNG as fuel when the vehicle is parked for rest or transit, so the stable supply of the cold source cannot be guaranteed.
