Abstract (en)

[origin: WO2019020953A1] The present invention relates to a method for managing an indirect reversible air conditioning circuit (1) in which a refrigerant circulates, said reversible air conditioning circuit (1) being able to operate in a heat-pump mode in which the refrigerant passes in succession into : a compressor (3), a condenser (5), a first expansion device (7), an evaporator (9), a second expansion device (11), and an evaporator-condenser (13), said air conditioning circuit (1) comprising a central control unit (40) able to control the opening of the first expansion device (7), said management method comprissing: a step of determining: the opening Cestim of the first expansion device (7), a reference superheating SHcomp_in_sp, SHcomp_in_sp being comprised between a minimum superheating SHcomp_in_sp_min and a maximum superheating Shcomp_in_sp_max, a step of opening the expansion device (7) according to Cestim and of controlling the superheating SHcomp_in by varying the opening of the expansion device (7) so as to achieve the reference superheating SHcomp_in_sp and keep SHcomp_in between SHcomp_in_sp_min and SHcomp_in_sp_max.
