Automotive Vehicle Thermal Conditioning System

Abstract

The invention relates to a thermal conditioning system (100) for a motor vehicle, comprising a refrigerant circuit (10) including: - a main loop (A) comprising successively: - a compressor (7), - a first heat exchanger (1) thermally coupled to an interior airflow (Fi) to the passenger compartment of a motor vehicle, - a first expansion valve (21), - a second heat exchanger (2) thermally coupled to an exterior airflow (Fe) to the passenger compartment of the motor vehicle, the second heat exchanger (2) comprising successively: - a first heat exchange section (2A), - a first refrigerant accumulation device (5), - a second heat exchange section (2B), - a second expansion valve (22), - a third heat exchanger (3), - a first bypass branch (B) comprising a third expansion valve (23) and a fourth heat exchanger configured to exchange heat with the interior airflow (Fi),in which the third expansion valve (3) is a thermostatic expansion valve.
