15. A method for defrosting a second heat exchanger of a heat pump circuit of an air conditioning device comprising:
-
the heat pump circuit, comprising at least one first heat exchanger with the air from the compartment, a compressor, the second heat exchanger with the outside air, and an expander device, and another heat pump circuit, comprising a first other heat exchanger with the air from the compartment, another compressor, a second other heat exchanger with the air from the outside, and another expander device, a heat storage reservoir, connected to the heat pump circuit, in parallel with said first heat exchanger with the air from the compartment, and connected to the other heat pump circuit, in parallel with said secondary heat exchanger with the air from the compartment, wherein; the heat pump circuit comprising the second heat exchanger to be defrosted, operates in a cold storage configuration, in which a refrigerant circulating in that heat pump circuit withdraws heat from the storage reservoir and gives that heat back to the second heat exchanger to be defrosted, the other heat pump circuit operates in a heating configuration of the compartment, in which a refrigerant circulating in that circuit withdraws heat from the second other heat exchanger of that other heat pump circuit and gives that heat back to the first other heat exchanger of that other heat pump circuit. - View Dependent Claims (16)
