Method for the diagnosis of an air conditioning system
First Claim
1. Method for the diagnosis of an air conditioning system having a condenser, an evaporator, an expansion device and a compressor having a variable stroke which can be set via a valve so as to range from a minimum stroke to a maximum stroke, in said method the maximum compressor stroke being set abruptly when the air conditioning system is running, whereupon a pressure impulse which arises in the high pressure side of the refrigerant circuit is measured in order to determine the degree of filling of the refrigerant circuit.

Abstract
In a method for the diagnosis of an air conditioning system having a condenser, an evaporator, an expansion device and a compressor, the stroke of which can be set via a valve, a maximum compressor stroke is set abruptly when the air conditioning system is running and a pressure impulse arising in the high pressure side of the refrigerant circuit is measured in order to determine the degree of filling of the refrigerant circuit.
