Claim 10:
11. A method for controlling a reversible heat pump assembly, the reversible heat pump assembly comprising a heat pump having a first side and a second side, the heat pump being configured to transfer heat from the first side to the second side or vice versa, wherein the reversible heat pump assembly is configured to be selectively set in either a heating mode or a cooling mode, wherein in the heating mode, the heat pump is configured to transfer heat from the first side to the second side, and wherein in the cooling mode, the heat pump is configured to transfer heat from the second side to the first side, the method comprising:
for a time period, determining a heating demand for heat to be delivered by the reversible heat pump assembly and a cooling demand for cold to be delivered by the reversible heat pump assembly,
identifying, based on the heating demand and the cooling demand, simultaneous demands of setting the reversible heat pump assembly in both the heating mode and the cooling mode, and
controlling, based on the heating demand, the cooling demand and the identified simultaneous heating and cooling demands, the setting of the reversible heat pump assembly in either the heating mode or the cooling mode such that in response to identified simultaneous heating and cooling demands, temporarily setting a heat pump of the reversible heat pump assembly to deliver heat at an output greater than an output indicated by the heating demand, thereby reducing a heating duty cycle and/or temporarily setting the heat pump to deliver cold at an output greater than an output indicated by the cooling demand, thereby reducing a cooling duty cycle.
