The invention relates to a defrosting and demisting device which is used in a pure electric bus, and the pure electric bus comprises a heat pump air conditioner. The defrosting and demisting device comprises a shell and a first heat exchanger, and the shell is provided with an air inlet, an air outlet and a first air duct communicating with the air inlet and the air outlet. The first heat exchanger is arranged in the first air duct and used for conducting heat exchange on cold water output by the heat pump air conditioner and airflow passing through the first air duct so that the airflow passing through the first air duct can be cooled. Aiming at the working condition of fogging in the automobile in summer, a refrigeration mode is adopted for demisting, the temperature difference between the inner side and the outer side of the windshield can be reduced to eliminate fog, and the demisting effect is improved.
本申请涉及一种除霜除雾装置,用于纯电动客车中,纯电动客车包括热泵空调。除霜除雾装置包括壳体和第一换热器,壳体设有进风口、出风口以及连通进风口和出风口的第一风道。第一换热器设置于第一风道内,第一换热器用于对热泵空调输出的冷水和经过第一风道内的气流进行热交换,以使经过第一风道内的气流降温。针对夏季车内起雾的工况,采用制冷方式除雾,能够降低挡风玻璃内侧与外侧的温差而使雾消除,提高了除雾效果。
