The invention discloses a vehicle-mounted cold energy utilization and air conditioning refrigeration combination device for a LNG (liquefied natural gas) heavy truck. The vehicle-mounted cold energy utilization and air conditioning refrigeration combination device comprises an LNG steel cylinder, a vaporizer, an air conditioner, a refrigerator, an engine and a controller, wherein the LNG steel cylinder is connected with the vaporizer through a pipeline; the vaporizer is connected with a circulating pump and an engine respectively; the circulating pump is connected with a heat exchanger, an air conditioner and the refrigerator through a first solenoid valve, a second solenoid valve and a third solenoid valve respectively; the heat exchanger, the air conditioner and the refrigerator are connected with the vaporizer through a pipeline respectively; a circulating pipeline is arranged between the heat exchanger and the engine; the controller is connected with the circulating pump, the first solenoid valve, the second solenoid valve and the third solenoid valve respectively. According to the vehicle-mounted cold energy utilization and air conditioning refrigeration combination device, a compressor is reduced, fuels for driving the compressor to operate are saved, the cold energy in a LNG gasification process is recycled, effects of saving the energy, reducing the consumption and reducing the cost are achieved, and the environment pressure is effectively relieved. Moreover, the vehicle-mounted cold energy utilization and air conditioning refrigeration combination device is simple in structure, simple in process and convenient to popularize and use.
