Abstract
The disclosed technology includes a heat pump having a thermal energy storage (TES) material. The heat pump can include a first heat exchanger to exchange heat between ambient air and refrigerant, a second heat exchanger to exchange heat between the refrigerant and air supplied to a climate-controlled space, and a third heat exchanger to exchange heat between the TES material and the refrigerant in a first fluid path and the refrigerant in a second fluid path. The heat pump can include a first compressor to circulate refrigerant to the first, second, and third heat exchangers and a second compressor to circulate refrigerant to the second and third heat exchangers. The first compressor can facilitate heat exchange between the ambient air and the TES material and the second compressor can facilitate heat exchange between the TES material and the air supplied to the climate-controlled space.
