Air-conditioning loop functioning as a pulse electro-thermal deicing heat pump
The invention relates to an air-conditioning loop for heating, ventilation, and/or air-conditioning equipment in which a coolant circulates. The loop including a compressor comprising a coolant outlet connected to a delivery pipe and a coolant inlet connected to a suction pipe. The loop also including an internal heat exchanger which is capable of functioning at least as a condenser, and which is connected to the compressor via the delivery pipe. The loop also including an external unit which is connected to the compressor via the suction pipe and which includes at least one external heat exchanger capable of functioning at least as an evaporator, with the internal heat exchanger being connected to the external unit via a first intermediate duct comprising at least one pressure-release member. The loop includes a deicing pipe connected to the compressor and/or to the delivery pipe, as well as to the external unit.
