    • In heating and cooling apparatus, for air conditioning and other use, molecules of working gas are excited by light irradiation and thereby cooled as the gas flows through a mirrored cooling cell (22). In a closed loop embodiment, radiation Q hv from a laser (20) or other light source travels as a beam (34) through window (21) and then bounces between opposing side mirrors (44) of cooling cell (22). It thereby passes through and kinetically cools a working gas flowing along gas flow path (32). The working gas is further cooled as its pressure drops when it passes through expander (24). As the gas passes through first heat exchanger (26), heat QA from the environment (38) to be cooled, is transferred from the gas. The working gas flows through conduit (40) to compressor or fan (28) where it is compressed; and it then flows through second heat exchanger (27) where heat QR is transferred from the gas to a heat sink (38'). The apparatus may be used simililarly to a common heat pump, for heating; or, similarly to common air conditioner, for cooling. In an open-end cooling apparatus embodiment, the gas flows from the cooling cell, through the first heat exchanger, and to atmosphere. The light source may be a 10.6 micron laser; or a 9-11 micron electric arc, a hot filament or the Sun. Working gases comprise N 2 and CO 2 ; exhaust gases of engines or fuel cells; and gases which comprise different molecular composition gases or different isotopic species of the same molecular composition gas.
    • 在加热和冷却装置中,对于空调和其他用途,工作气体分子被光照射激发,并且随着气体流过镜像冷却单元(22)而被冷却。 在闭环实施例中,来自激光(20)或其他光源的辐射Q> hv通过窗口(21)作为光束(34)行进,然后在冷却单元(22)的相对的侧反射镜(44)之间弹跳。 从而通过并动态地冷却沿着气体流路(32)流动的工作气体。 当工作气体通过膨胀器(24)时,其压力进一步降低。 当气体通过第一热交换器(26)时,来自待冷却的环境(38)的热量QA从气体传送。 工作气体通过导管(40)流到压缩机或风扇(28),压缩机或风扇(28)被压缩; 然后流过第二热交换器(27),其中热量QR从气体传递到散热器(38')。 该设备可以类似于普通热泵使用,用于加热; 或类似于普通空调器进行冷却。 在开放式冷却装置实施例中,气体从冷却单元流过第一热交换器,并流到大气中。 光源可以是10.6微米的激光器; 或9-11微米电弧,热丝或太阳。 工作气体包括N> 2 <和CO> 2 < 发动机或燃料电池的废气; 以及包含相同分子组成气体的不同分子组成气体或不同同位素物质的气体。
