LNG refrigerator car

Abstract

The invention belongs to the field of cold-chain transportation, and provides an LNG refrigerator car. The LNG refrigerator car comprises an intelligent temperature-control refrigeration system and an anti-explosion early-warning processing system. The two systems are intelligently controlled through an intelligent anti-explosion temperature-control box, a refrigeration pipeline and a standby power air-supply pipeline are included, on-off of LNG can be regulated according to the temperature of a heat-insulation compartment, and the LNG refrigeration efficiency is improved through the structural design of an evaporator and an air cooler; and if leakage occurs, a fuel gas alarm gives out an alarm, the refrigeration pipeline is closed by the corresponding system, the standby power air-supply pipeline is opened for supplying air to an engine, the refrigerator car travels to a safe area, and thus disastrous consequences are avoided.

Description

technical field [0001] The invention is applied in the field of cold chain transportation, and in particular relates to a refrigerated truck using LNG for refrigeration. Background technique [0002] At present, traditional refrigerated vehicles use mechanical refrigeration, and the working principle is to use vapor compression refrigeration. With the development of energy sources, liquefied natural gas (LNG) gradually enters the field of life. LNG is generally stored in LNG tanks at a pressure of 0.1-0.2 MPa and at -163°C. It releases a large amount of gas during its heat-absorbing vaporization from a liquid state to a gaseous state. In terms of cold energy, there have been a variety of refrigerated vehicles using low-temperature LNG for refrigeration. The invention patent of patent number CN201210010484.9 "A cold energy utilization device for liquefied natural gas refrigerated vehicles" and the invention patent of patent number CN201520030571.X "a commercial refrigerated ...

AI Technical Summary

Problems solved by technology

[0003] Natural gas is becoming more and more popular as a non-polluting clean energy. In the field of cold chain transportation, LNG can be used as a transportation energy and a cold source, and it will be widely used. However, natural gas, like coal gas, is bringing people While providing convenience, there are also potential safety hazards, especially the leakage of refrigerated vehicles that use LNG to provide cold energy, which will cause catastrophic consequences such as explosions
