Automotive automatic air conditioning system with variable desplacement compressor.

摘要

In an automotive automatic air conditioning system having at least a variable displacement compressor (2), a condenser (3), an expansion valve (6), and an evaporator (4); an improvement comprising a refrigerant temperature sensor disposed between the outlet of the expansion valve (6) and the inlet of the evaporator (4) for detecting a refrigerant temperature, and a controller (40) for setting a target refrigerant temperature are disclosed. The controller (40) controls the discharge of refrigerant from the compressor (2) such that the refrigerant temperature reaches the target refrigerant temperature.
