Heat powered cycles are of great interest as they enable reduced electric power consumption. Therefore, they can lower the load on electric power plants and distribution infrastructure. Many systems incorporate compressors for driving thermodynamic cycles and processes, and these compressors are usually electrically driven. In the framework of research on a sorption Joule-Thomson cryogenic cooler, a three-stage sorption compressor is designed, manufactured, and tested. The experimental results are reported and analyzed in the current manuscript. Nine experiments are reported, with one, two, and three compression stages, in which the experiments differ in the number of sorption cells at every compression stage and the operating conditions. The results of the experimental apparatus validate a numerical model and show the ability to construct and operate sorption compressors. All nine experiments operate with nitrogen, which is the required refrigerant in the cryogenics cooling system of the current research. Nitrogen is a weakly adsorbed gas, and so the reported efficiencies are relatively low, around 0.5% of the Carnot efficiency. However, the current work proves the technology's maturity and suitability for many other applications, especially where the required working fluids are more intensively adsorbed gases.

热动力循环引起了极大的兴趣，因为它们可以降低电力消耗。因此，它们可以降低发电厂和配电基础设施的负荷。许多系统都包含用于驱动热力学循环和过程的压缩机，这些压缩机通常是电动的。在吸附式焦耳-汤姆逊低温冷却器研究框架内，设计、制造并测试了三级吸附式压缩机。实验结果在当前的手稿中进行了报告和分析。报告了九个实验，包括一个、两个和三个压缩阶段，其中每个压缩阶段的吸附单元数量和操作条件不同。实验装置的结果验证了数值模型并显示了构造和操作吸附式压缩机的能力。所有九个实验都使用氮气进行，这是当前研究的低温冷却系统中所需的制冷剂。氮气是一种弱吸附气体，因此报告的效率相对较低，约为卡诺效率的 0.5%。然而，目前的工作证明了该技术的成熟度和适用性，适用于许多其他应用，特别是在所需的工作流体是更强烈吸附的气体的情况下。卡诺效率的 5%。然而，目前的工作证明了该技术的成熟度和适用性，适用于许多其他应用，特别是在所需的工作流体是更强烈吸附的气体的情况下。卡诺效率的 5%。然而，目前的工作证明了该技术的成熟度和适用性，适用于许多其他应用，特别是在所需的工作流体是更强烈吸附的气体的情况下。
