The invention provides a vapor compression cycle refrigeration method for a sealed cabin in a vacuum environment. The method comprises the steps that firstly, gas carrying heat in the sealed cabin is conveyed to a first heat exchanger; secondly, the first heat exchanger transfers heat to a liquid first medium, and the liquid first medium absorbs heat and is vaporized into a low-temperature low-pressure gaseous first medium; thirdly, the low-temperature and low-pressure gaseous first medium is compressed into a high-temperature and high-pressure gaseous first medium, and the high-temperature and high-pressure gaseous first medium is sent to a second heat exchanger fourthly, the second heat exchanger transfers heat carried by the high-temperature and high-pressure gaseous first medium to a second medium so that the second medium can be liquefied into the high-temperature and high-pressure gaseous first medium; fifthly, throttling and pressure reducing treatment is conducted on the high-temperature and high-pressure liquid first medium, and the low-temperature and low-pressure liquid first medium is conveyed to the first heat exchanger; and sixthly, the steps 1-5 are repeated to complete refrigeration in the sealed cabin in the vacuum environment. By means of the technical scheme, the technical problem that in the prior art, a sealed cabin in the vacuum environment cannot be refrigerated is solved.

    本发明提供了一种用于真空环境中密封舱体的蒸汽压缩循环制冷方法,该方法包括:一,将密封舱体内的携带热量的气体送至第一换热器;二,第一换热器将热量转移至液态第一介质,液态第一介质吸热汽化为低温低压气态第一介质;三,将低温低压气态第一介质压缩为高温高压气态第一介质,将其送至第二换热器;四,第二换热器将高温高压气态第一介质所携带的热量转移至第二介质以液化为高温高压液态第一介质;五,对高温高压液态第一介质进行节流减压处理,将低温低压液体第一介质送至第一换热器;六,重复步骤一至五以完成真空环境中密封舱体内的制冷。应用本发明的技术方案,以解决现有技术中无法对真空环境下的密封舱体进行制冷的技术问题。
