The results show that the cooling capacity of LNG heavy truck is 6.150 kW in the upper section of the air-conditioning system, the cold storage capacity is 0.551 kW. The air conditioning refrigeration capacity of the stationary section is 4.201 kW, the cold storage capacity is 0.420 kW. The cooling capacity of the downhill section is 2.902 kW, and the cooling capacity of the regenerator is greater than that of 0.598 kW. The system can control the storage quantity rationally by controlling strategy, and meet the demand of stable cooling of the air conditioning system under the whole road condition of LNG heavy truck.
