REGULATING DEVICE FOR A COOLANT CIRCUIT OF AN AIR CONDITIONING SYSTEM

摘要

The invention relates to a regulating device for a coolant circuit of an air conditioning system. Said coolant circuit is divided into a high pressure side and a low pressure side by a compressor and an expansion element. The regulating device comprises a regulating part (8 to 12) located on the high pressure side and has a regulating part (1 to 7) located on the low pressure side for respectively regulating one or several system components which can be regulated and which are located on the high pressure side or on the low pressure side. According to the invention, both regulating parts are coupled to one another in that at least one influencing quantity (ys) of the one regulating part (1 to 7) forms a coupling quantity which is injected into the other regulating part (8 to 12) as an influencing quantity which is also effective in said regulating part. The invention is used e.g. for CO2 air conditioning systems in motor vehicles.
