換弁を備えたことを特徴とする冷暖房装置。(1) A high-temperature side displacer and a low-temperature side displacer that reciprocate out of phase, a high-temperature side cylinder that is divided into a high-temperature chamber and a medium-temperature chamber by the high-temperature side displacer, and a high-temperature side cylinder that communicates with the high-temperature chamber and is connected to the outside from the outside. A high-temperature side heat exchanger to be heated, a heat storage device and a medium-temperature side heat exchanger arranged between this heat exchanger and a medium-temperature side heat exchanger, and a low-temperature side displacer are used to divide the room into a low-temperature chamber and a medium-temperature chamber. A refrigerator is composed of a low-temperature side cylinder, a low-temperature side heat exchanger and regenerator disposed between the low-temperature chamber and the medium-sized greenhouse, and a communication chamber that communicates the two medium-sized greenhouses. The heat exchanger is connected to the indoor heat exchanger, and the medium temperature side heat exchanger is connected to the outdoor heat exchanger for heat radiation. During heating, the medium temperature side heat exchanger is connected to the indoor heat exchanger, and the low temperature side heat exchanger is connected to the indoor heat exchanger. An air-conditioning/heating device characterized by comprising switching valves connected to respective heat-absorbing outdoor heat exchangers.
