とに接続したことを特徴とする冷暖房装置。1 A cylinder filled with working gas, a high-temperature side displacer and a low-temperature side displacer that divide the inside of this cylinder into a high temperature chamber, a medium chamber, and a low temperature chamber, and a gas flow path that connects the high temperature chamber and the medium chamber. A high-temperature side heat exchanger, a high-temperature side regenerator, and a medium-temperature side heat exchanger for heating the working gas are placed in the gas flow path, and a low-temperature side heat exchanger and a low-temperature side heat exchanger are placed in the gas flow path connecting the cold room and the medium temperature room. In an apparatus having a refrigerator comprising a regenerator, a medium-temperature pipe line through which a medium heated by the medium-temperature side heat exchanger flows, a low-temperature pipe line through which a medium cooled by the low-temperature side heat exchanger flows; The medium-temperature pipe line and the low-temperature pipe line are connected to the indoor heat exchanger and the outdoor heat exchanger via a flow path switching valve. A heating and cooling device characterized by being connected to an exchanger.
