According to the method, heat delivered to the cabin (H) comes from a hot source ( 18 ) of a heat pump ( 12 ) comprising a main refrigerant circuit ( 14 ) taking heat from a cold source ( 16 ) to transfer it to the hot source ( 18 ). Heat taken from the cold source ( 16 ) comes from a flow of air re
According to the method, heat delivered to the cabin (H) comes from a hot source ( 18 ) of a heat pump ( 12 ) comprising a main refrigerant circuit ( 14 ) taking heat from a cold source ( 16 ) to transfer it to the hot source ( 18 ). Heat taken from the cold source ( 16 ) comes from a flow of air recycled from the cabin. The cold source ( 16 ) has a refrigerant/coolant heat exchanger ( 24 ) thermally coupling the main circuit ( 14 ) to a first secondary coolant circuit ( 26 ) capable of being selectively connected to an outside heat exchanger ( 30 ) and to a cold heat exchanger ( 32 ). Air flow circuits have an inlet for admitting air recycled from the cabin, an outlet for delivering air to the outside of the vehicle, first connection means for connecting the recycled air inlet to the upstream end of the cold heat exchanger ( 32 ), and second connection means for connecting the downstream end of said cold heat exchanger ( 32 ) to the outside outlet.
