| 电动汽车没有足够的余热可供冬季取暖，因此将热泵引进电动车具有重要意义。文章对两种汽车热泵系统：三换热器与四通阀的热泵系统进行了分析研究。测试结果表明：在大部分工况下，两个系统的能力相近，只相差10~50W，但四通阀系统的COP要比三换热器系统高7%~15%，压缩机功率则比三换热器系统低50~150W。 |

| Abstract: |
| Electric vehicles don’t have enough waste heat for heating in winter, so the introduction of heat pump system to electric vehicles is of great significance. Two kinds of heat pump system with three heat exchangers and four-way valve are researched in the article, and the result shows that: in most conditions, the two systems’ ability are similar, the difference between them is only 10W to 50W, but the COP of four-way valve system is 15% ~ 18% higher than that of three heat exchanger system, and the compressor power of four-way valve system is 50 to 150W lower than that of three heat exchanger system. |
