Air-Conditioning Loop Functioning As A Pulse Electro-Thermal Deicing Heat Pump

An air conditioning loop (200) for a heating, ventilation and/or air conditioning system in which a coolant circulates and which is capable of functioning in at least one heat pump mode of operation in order to heat a passenger compartment, the air-conditioning loop comprising at least:

• a compressor (210) comprising a coolant outlet connected to a delivery pipe (20) and a coolant inlet connected to a suction pipe (21);
• an internal heat exchanger (220) which is capable of functioning at least as a condenser, and which is connected to the compressor (210) via the delivery pipe (20);
• and
• an external unit (230) which is connected to the compressor (210) via the suction pipe (21) and which includes at least one external heat exchanger (250) capable of functioning at least as an evaporator, with the internal heat exchanger (220) being connected to the external unit (230) via a first intermediate pipe (22) comprising at least one expansion element (300);
• wherein the air conditioning loop (200) includes a deicing pipe (30) connected to the compressor (210) and/or to the delivery pipe (20), as well as to the external unit (230).
