  • Systems and methods for capacity modulation through eutectic plates
    Patent number: 11014427
    Abstract: A system may include a compressor, a first heat exchanger, a first working fluid flow path, and a second working fluid flow path. The first heat exchanger receives working fluid discharged from the compressor. The first working fluid flow path may receive working fluid from the first heat exchanger and may include a second heat exchanger and a first control valve that is movable between a first position allowing fluid flow through the second heat exchanger and a second position restricting fluid flow through the second heat exchanger. The second working fluid flow path may receive working fluid from the first heat exchanger and may include a third heat exchanger and a second control valve that is movable between a first position allowing fluid flow through the third heat exchanger and a second position restricting fluid flow through the third heat exchanger.
