FIELD: engines and pumps.
SUBSTANCE: climate control system includes a compressor with two located downstream channels that can be selectively used to work in different modes. When the compressor is switched off, the valves installed in each channel immediately after the compressor are closed, as a result of which the refrigerant and oil mixture remains in the compressor.
EFFECT: better lubrication of the compressor when it is turned on again.
