AIR CONDITIONING THERMODYNAMIC LOOP INTEGRATED IN A HEATING, VENTILATION AND/OR AIR CONDITIONING SYSTEM A VEHICLE, IN PARTICULAR AN ELECTRIC PROPULSION VEHICLE

摘要

The invention relates to an air conditioning thermodynamic loop (4) that generates a coolant flow and that includes a four-way valve (6) for reversing the coolant flow direction in a first portion (7) of the air conditioning thermodynamic loop (4), arranged between a first opening (9) and a second opening (10) of the four-way valve (6) and including at least one air-based heat exchanger (11) and a first expansion member (12). The first portion (7) of the air conditioning thermodynamic loop (4) includes an inner heat exchanger (15) provided between the first expansion member (12) and the second opening (10) of the four-way valve (6).
