Abstract
A system off configuration for an automotive climate control system is provided. The climate control system includes a compressor having two downstream flow paths. The two downstream flow paths may be selectively used to provide multiple modes of operation. When the compressor moves to an off condition the valves found in each flow path immediately downstream from the compressor are closed so that a refrigerant oil blend is kept in the compressor.
