Engine as the power source of refrigeration system during the night/midway parking causes large energy consumption and much exhaust emission. To solve this problem, a refrigeration system supplied by solar auxiliary power of refrigerator car was proposed. The dynamic mathematical model was established and matching methods of the system were proposed. The effectiveness of the model was verified by experiments and the cooling performance of the solar auxiliary power was analyzed. The results show that the power generation of the system is able to supply the refrigerator for continuous operating for 4.45 h in a day. Temperature in the compartment needs about 580 s to drop from ambient temperature to the specified value at three typical driving speeds and then remains stable. Compared with the refrigeration effect of traditional refrigerator car, the system has remarkable energy-saving effect and increases the delivery range of the refrigerator car.
