Heat pump system with reversible heat exchanger and series / parallel switching of said reversible heat exchanger by a four-way actuator

Abstract

The invention relates to a heat pump system (1) for a motor vehicle, comprising: a compressor (3), a first condenser (4) disposed downstream of the compressor (3), and a single valve (14) switchable between: a first configuration (18) in which the valve (14) allows two-phase fluid circulation in the primary circuit (2) in parallel in a first assembly (9) comprising a heat exchanger, referred to as a reversible heat exchanger (10), disposed downstream of a first expansion valve (11) of the first assembly (9), and in a second assembly (6) comprising a second evaporator (7) disposed downstream of a second expansion valve (8), and a second configuration (15) of the valve (14) in which the valve (14) allows two-phase fluid circulation in the primary circuit (2) in series in the first assembly (9) and in the second assembly (6).
