Краткое описание

The waste heat characteristics of the exhaust gases from the coach engine were analyzed at different coach running speeds and different gears. Based on the waste heat load, the cycle thermal calculation results and the given operating conditions, the structural parameters of the main devices in the absorption−compression hybrid refrigeration cycles (ACHRC) were determined. The conditions of the temperatures of cooling air, condensation, and evaporation are 35°C, 55°C, and 3°C, respectively, and the coach air-conditioning load is 30 kW. The performance of the ACHRC was investigated by coupling the heat transfer equations for the devices in the ACHRC and the cycle thermal calculation equations. The results indicate that the absorption refrigeration subcycle (ARSC) driven by the gases can completely meet the coach cooling requirement when the coach running speed reaches 105 km·h−1. The cooling load is fully supplied by the compression refrigeration subcycle (CRSC) powered by the engine output when the coach running speed is lower than 40 km·h−1.
