Abstract:
An externally-controlled variable displacement compressor (EVDC) cold-start method is described including, during an EVDC cold-start procedure, iteratively alternating an amount of a control current supplied to an electronic control valve (ECV) associated with the EVDC between no control current and a full control current. Systems for implementing the described method are provided.
