Study on optimization of exhaust hole of scroll compressor for automobile air conditioning
In order to reduce the flow loss and increase the discharge pressure,the structure of vent hole is optimized to solve the flow loss caused by the change of gas flow at the vent hole of scroll compressor of automobile air conditioner.The transient simula-tion of the exhaust process of the scroll compressor with different vent structures is carried out by the three-dimensional dynamic mesh model.It is found that the larger cross-sectional area of the cashew-shaped vent makes it have better opening characteristics,which can effectively reduce the exhaust loss and improve the exhaust stability.After fur-ther diffusion optimization of the cashew vent,it is found that it can more effectively re-duce the exhaust velocity and increase the exhaust pressure.
