Heat Pump System With Thermal Energy Storage

A climate-control system comprising:

• a first fluid circuit including a compressor, a thermal energy storage device, a first outdoor heat-exchanger conduit, a second outdoor heat-exchanger conduit, and a third outdoor heat-exchanger conduit, wherein the compressor circulates a first fluid through the thermal energy storage device, the first outdoor heat-exchanger conduit, the second outdoor heat-exchanger conduit, and the third outdoor heat-exchanger conduit;
• and
• a second fluid circuit including a first pump, a second pump, a first indoor heat-exchanger conduit, a second indoor heat-exchanger conduit, and a third indoor heat-exchanger conduit, wherein the second fluid circuit defines a first closed loop including the first pump and the first indoor heat-exchanger conduit, wherein the second fluid circuit defines a second closed loop including the second pump and the third indoor heat-exchanger conduit,
• wherein:
• the first and second fluid circuits are fluidly isolated from each other,
• the first outdoor heat-exchanger conduit is in a heat transfer relationship with the first indoor heat-exchanger conduit,
• the third outdoor heat-exchanger conduit is in a heat transfer relationship with the third indoor heat-exchanger conduit,
• the climate-control system is operable in a plurality of cooling modes and in a plurality of heating modes,
• the second indoor heat-exchanger conduit is a part of the first closed loop in the heating modes, and
• the second indoor heat-exchanger conduit is a part of the second closed loop in the cooling modes.
