Embodiment Construction

[0025] figure 1 Shown in is a conventional air conditioning circuit of a motor vehicle with an engine, comprising a compressor 10 of a refrigerant fluid, which may be an organic, inorganic or fusible fluid. Supercritical carbon dioxide CO can be quoted 2 Designated as R134A, 1234yf or GAR ("Global Alternative Refrigerant"), as non-limiting examples. Downstream of the compressor 10, the pressurized refrigerant fluid passes through a heat exchanger 11, which is called a "gas cooler" for carbon dioxide or a "condenser" for R134A, since in this case the initial The refrigerant in the vapor phase leaves the condenser in a liquid state.

[0026] exist figure 1 In some examples, the exchanger 11 may be a water type exchanger, or an air type exchanger directly cooled by outside air.

[0027] The refrigerant fluid is then directed towards the safety valve 12 whereby the refrigerant fluid is cooled before entering the evaporator 13 where heat exchange then takes place between the ai...

Abstract

The invention relates to a method for managing a hybrid compressor (10) for an air-conditioning circuit of a motor vehicle with a heat engine, said hybrid compressor being adapted, on the one hand, to be driven by said heat engine and, on the other hand, to be driven by said heat engine The compressor ( 10 ) is driven by the electric motor ( 20 ) during periods when the drive to the compressor ( 10 ) is interrupted. According to the invention, during a drive break, the method comprises starting the electric motor (20) before the start of the drive break. The invention can be used in air-conditioned motor vehicles which have a heat engine and are provided with an automatic stop and restart system.

Description

technical field [0001] The invention relates to a method for managing a hybrid compressor of an air-conditioning circuit of a motor vehicle with an engine. [0002] The invention finds a particularly advantageous application in the field of air conditioning of motor vehicles with engines equipped with an automatic stop and restart system, such as a system capable of implementing the function known by the term "stop and start". Background technique [0003] Under some conditions, the "stop and start" function includes automatically causing a complete stop of the engine when the vehicle itself has stopped, and then automatically restarting the engine after, for example, a driver action interpreted as a restart request. [0004] A typical situation for implementing a "stop and start" function is that of stopping at a red light. When the vehicle is stopped at the light, the "Stop" mode of the "Stop and Start" function causes the engine to stop automatically, and the vehicle the...
