提出了一个由太阳能驱动的新型吸收制冷循环。论文将热变器原理用于吸收制冷，从而大大提高了吸收制冷的循环效率。详细介绍该新型循环的热力学模型，同时以一个典型的太阳日照为例，计算了新循环的性能系数（ＣＯＰ）、冷凝热、理论极限制冷温度和制冷量，并与传统循环进行了比较。结果表明，新循环不仅克服了传统循环在热源工况不稳定时将导致系统工况不稳定甚至不能工作的缺点，而且还具有更高ＣＯＰ值。 A new solar-powered absorption refrigeration cycle is proposed. Papers will be used to absorb the principle of heat exchange refrigeration, thereby greatly improving the absorption refrigeration cycle efficiency. The thermodynamic model of the new cycle is introduced in detail. Taking a typical solar sunshine as an example, the performance coefficient (COP) of the new cycle, the condensation heat, the theoretical limit refrigeration temperature and the cooling capacity are calculated and compared with the traditional cycle. The results show that the new cycle not only overcomes the shortcomings of the traditional cycle when the heat source is not stable, it will lead to instability or even failure of system operation, but also has higher COP value.
