There is noise in the directly heat pump air conditioner system in the electrical vehicle while the heat pump widely using due to its high efficiency and rapid responding speed. The sound source is confirmed to relate to the refrigerant pulsation of the air conditioner system in the vehicle through the experimental analysing. Then the principal of the refrigerant pulsation and the scroll compressor are provided. So the designed muffler which is installed in discharge pipeline of the heat pump air conditioner system in vehicle is used to reduce the refrigerant pulsation into the specification. Thus the vehicle interior noise is reduced significantly. At last the conclusions proved that the NVH performance designing rules in directly heat pump air conditioner system must be considered before.
