The invention provides an automotive heat pump air conditioning system and a passenger car, and belongs to the technical field of passenger cars. The heat pump air conditioning system comprises an air conditioning unit, a top exhaust duct arranged at the top of a vehicle, a bottom exhaust duct arranged at the bottom of the vehicle and an air duct air inlet. An air duct baffle is arranged at the air duct air inlet, the air duct air inlet is divided into an upper air inlet and a lower air inlet, and air is supplied to the top exhaust duct and the bottom exhaust duct through the upper air inlet and the lower air inlet respectively; an air volume distribution mechanism is further arranged at the air duct air inlet, and the air inlet volume of the upper air inlet and the lower air inlet of the air conditioner in different modes is controlled through a proportional air door. According to different densities of hot air and cold air, air is supplied mainly through the bottom exhaust duct in the air conditioner heating mode, air is supplied mainly through the top exhaust duct in the air conditioner refrigeration mode, the uniformity of the temperature in a vehicle cabin is guaranteed, and the comfort and experience feeling of passengers are improved.
本发明提供了一种车用热泵空调系统及客车,属于客车技术领域。热泵空调系统包括空调机组、用于设置在车辆顶部的顶部排风道、用于设置在车辆底部的底部排风道、风道进风口;并在风道进风口处设置风道挡板,将风道进风口分为上进风口和下进风口,通过上进风口和下进风口分别向顶部排风道和底部排风道送风;还在风道进风口处设置了风量分配机构,通过比例风门控制空调在不同模式下上进风口和下进风口的进风量。本发明考虑到热风与冷风的密度不同,在空调制热模式下以底部排风道送风为主,在空调制冷模式下以顶部排风道送风为主,保证车舱内温度的均匀性,提高乘客的舒适性与体验感。
