Reed valves are widely used in hermetic reciprocating compressors for domestic refrigeration. They are crucial components in terms of efficiency, cooling performance and reliability of the compressor. While reed valves already cause a significant proportion of the thermodynamic losses in fixed speed compressors, they cause even more challenges in variable speed compressors. Especially in variable speed compressors, a further improvement of the reed valve dynamics requires the consideration of a new valve concept. In this work, a new and cost-effective concept of a mechanically assisted suction reed valve is introduced. Simulation based response modelling and a multi-response optimization approach are applied to systematically optimize the design. Simulations between 1500 rpm and 5000 rpm indicate the strengths and weaknesses of individual optimized design variants over a wide compressor speed range. Calorimeter and valve dynamics measurements show considerable improvements of the COP and the valve impact velocity.

多响应优化应用于封闭式往复式压缩机的机械辅助簧片阀

簧片阀广泛用于家用制冷的封闭式往复式压缩机。就压缩机的效率,冷却性能和可靠性而言,它们是至关重要的组件。尽管簧片阀已经在定速压缩机中造成了很大比例的热力学损失,但它们却给变速压缩机带来了更大的挑战。特别是在变速压缩机中,簧片阀动力学的进一步改善需要考虑新的阀概念。在这项工作中,引入了一种新的,具有成本效益的机械辅助吸入簧片阀的概念。基于仿真的响应建模和多响应优化方法被应用于系统地优化设计。1500 rpm至5000 rpm之间的仿真表明,在宽的压缩机转速范围内,各个优化设计方案的优缺点。量热仪和阀门动力学测量结果表明,COP和阀门冲击速度有了显着提高。
