史透林循环制冷机按照封闭的回热式热力循环工作,工质在不同的温度下压缩和膨胀。一般史透林循环制冷机都使用气态工质,但应用两相、两组份工质后,制冷量可能得到显著改善。这两相、两组份工质包括一种气态载体以及一种在低温区域为液态而在环境温度空间为气态的组份,在回热过程中这一组份发生相变。这样就增加了工质压力波动范围,因而也就增加了制冷量,无须在尺寸、重量或成本方面增加多少代价。改善的程度取决于制冷机的工作条件和特殊设计。本文探讨了某些参数变化的影响。
History of the Turbine circulating refrigerator in accordance with the closed regenerative heat cycle work, working fluid at different temperatures, compression and expansion. The general history of TURF circulation refrigerators use gaseous working fluid, but the application of two-phase, two-component refrigerant, the cooling capacity may be significantly improved. The two-phase, two-component working medium includes a gaseous carrier and a component that is liquid at low temperature and gaseous at ambient temperature and undergoes phase transformation during the reheat. This increases the pressure fluctuation range of the working fluid and therefore increases the cooling capacity without any additional cost, size, weight or cost. The degree of improvement depends on the operating conditions and the special design of the refrigerator. This article explores the impact of some parameter changes.
