Air conditioning device for a heating installation, a ventilation installation and/or a air conditioning installation

摘要: The loop (12) has a compressor (14), first heat exchanger (16) for heating an air flow distributed into cab interior of motor vehicle, expansion device (18) e.g. electronic valve, exterior (20) and second (24), that are arranged according to direction closed circuit circulation coolant in the loop. A thermal storage (28) is connected outlet exchanger. bypass arm (36) parallel with member. chosen from group comprising subcritical fluid, such as 1, 2-Tetrafluoroethane (R134A) or supercritical fluid R744 carbon dioxide.
