    • A thermally operated refrigerator includes a hot space absorbing a heat from an outer heat source at a high temperature, an ambient space having a first portion and a second portion, a heat accumulator disposed between the hot space and the first portion of the ambient space for establishing a first fluid circuit in which an amount of operating fluid is filled, a hot displacer whose reciprocal movement establishes a periodical movement of the operating fluid in the first fluid circuit for rejecting the heat absorbed at the hot space to the first portion of the ambient space, a cold space absorbing a heat from a load at a low temperature, a cooler disposed between the cold space and the second portion of the ambient space for establishing a second fluid circuit in which an amount of operating fluid is filled, a cold displacer whose reciprocal movement establishes a periodical movement of the operating fluid in the second fluid circuit for rejecting the heat absorbed at the cold space to the second portion of the ambient space, a mechanism for driving the hot displacer and the cold displacer concurrently, an additional ambient space having a variable volume and disposed between the first portion and the second portion of the ambient space.
    • 热操作的冰箱包括在高温下吸收来自外部热源的热量的热空间,具有第一部分和第二部分的环境空间,设置在热空间和周围空间的第一部分之间的蓄热器, 建立其中填充有一定量的工作流体的第一流体回路,其往复移动建立工作流体在第一流体回路中的周期性运动,用于排除在热空间处吸收的热量至环境的第一部分 空间,在低温下从负载吸收热的冷空间;冷却器,设置在冷空间和环境空间的第二部分之间,用于建立其中填充有一定量的工作流体的第二流体回路;冷置换器 其往复运动建立了工作流体在第二流体回路中的周期性运动,用于排除在冷空间吸收的热量 环境空间的第二部分,用于同时驱动热置换器和冷置换器的机构,具有可变容积并且设置在环境空间的第一部分和第二部分之间的附加环境空间。
