The dynamic characteristics of automobile operation and the changeable external environment put forward some special requirements for the performance and structure of automobile air conditioner compressor, which is shown in:
(1) In order to have good low-speed performance, the compressor in the automotive engine at low speed and no-load with greater refrigeration capacity and high efficiency.
(2) Low input power when driving at high speed, which not only saves fuel consumption, but also reduces the power consumption of engine used in air conditioning, and enhances the vehicle's own dynamic performance.
(3) The compressor to small lightweight, this can save the car space, installation location convenient, and save material and fuel consumption.
(4) to withstand the test of poor operating conditions, there is a high degree of reliability and durability. At idle speed, the car engine cabin temperature is sometimes up to 80 Shan condensation pressure is high, it requires the compressor can withstand high temperature and high pressure and limited overload. There is always a bumpy vibration on the road, which also requires the compressor to have good seismic performance and reduce the leakage of refrigerant to the lowest degree.
(5) Do not adversely affect the car. Compressor operation is required to be stable, small vibration, low noise, start and stop on the engine speed of the impact of small, starting torque small.
