摘要：

为了满足LNG重卡驾驶空间的制冷需求，设计了一种具有蓄冷功能的LNG重卡冷能利用空调系统，构建了全路况行驶模型，并对LNG重卡在上坡段、平稳段和下坡段全路况下的制冷性能和影响因素进行了分析。结果表明：LNG重卡冷能利用空调系统上坡段的空调制冷量是6.150 kW，蓄冷量是0.551 kW；平稳段的空调制冷量是4.201 kW，蓄冷量是0.420 kW；下坡段的空调制冷量是2.902 kW，蓄冷器释放的冷量大于0.598 kW。该系统通过控制策略对蓄冷量进行合理的调控，满足LNG重卡全路况下空调系统稳定的供冷需求。

In order to meet the refrigeration demand of LNG heavy truck driving space, an air conditioning system for the cold energy of LNG heavy truck with cool storage function is designed, and the whole road traffic model is constructed, and the refrigeration performance and the influencing factors of the LNG heavy truck in the uphill section, the stationary section and the downhill section are analyzed. 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.
