摘要：

The air conditioner of diesel vehicles consumes the fuel of engine, which reduces the economic benefits of diesel vehicles especially in areas with strong solar radiation. To solve this problem, a set of solid sorption vehicle air-conditioning system driven by the exhaust gas of engine is built. The system consists of two solid sorption beds filled with CaCl2/MnCl2/expanded natural graphite treated with sulphuric acid (ENG-TSA) composite sorbent, an evaporator, a condenser, a liquid storage tank, and valves. It uses ammonia as refrigerant. Natural wind cools the solid sorption bed and provides continuous cooling effect to the cabin, while the heating phase for generation is completed by exhaust gas. The system is simulated, and the refrigeration effect is tested by experiments. The simulation results show that the optimal cycle time of the system is 45 min, and theoretical average cooling power of the system can reach more than 3.5 kW, while the system COP is between 0.2 and 0.25. The experimental results show that the system can generate an average cooling capacity of 3 kW under the exhaust gas temperature of 230℃. Under the ambient temperature of 40℃, the average temperature difference of the system at the inlet and outlet of the evaporator is 6.5℃, and the average cooling capacity is 3.2 kW. © 2020, Chemical Industry Press Co., Ltd.
