The invention discloses a system for refrigerating LNG automobile by utilizing gasification waste cold. The LNG automobile comprises an LNG engine, a feeding mechanism and a heat exchanger, the LNG engine is provided with a water tank, the feeding mechanism comprises an LNG storage tank and a gasifier, the gasifier comprises a first heat exchange box and a gasification pipe, the gasification pipe is arranged in a first heat exchange cavity, one end of the gasification pipe is communicated with a gas inlet of the LNG engine, and the other end of the gasification pipe is communicated with the LNG storage tank; the heat exchanger comprises a second heat exchange box and a cold water pipe. The technical scheme provided by the invention has the beneficial effects that cold energy released in the LNG liquefaction process is used for refrigerating hot water in the water tank of the LNG engine, and cold water obtained after refrigeration is used for cooling air in the second heat exchange box and then flows back into the water tank of the LNG engine; since the second heat exchange box communicates with the interior of the automobile, the cold air in the second heat exchange box can exchange heat with the air in the vehicle, so that the temperature in the vehicle is reduced, and waste of cold energy released in the LNG liquefaction process is avoided.

    本发明公开了一种LNG汽车利用气化余冷制冷系统,包括LNG发动机、供料机构及换热器,LNG发动机具有水箱,供料机构包括LNG储罐及气化器,气化器包括第一换热箱及气化管,气化管内置于第一换热腔内,气化管的一端与LNG发动机的进气口连通,气化管的另一端与LNG储罐连通;换热器包括第二换热箱及冷水管。本发明提出的技术方案的有益效果是:通过将LNG液化过程中释放的冷量用于对LNG发动机的水箱内的热水进行制冷,并将制冷后的得到的冷水用于对第二换热箱内的空气进行降温后流回LNG发动机的水箱内,由于第二换热箱与车内连通,从而第二换热箱内的冷空气可与车内空气进行热交换,以降低车内温度,避免了LNG液化过程中释放的冷量的浪费。
