无分凝器的氨水吸收式制冷循环系统研究

在常规单级氨水吸收式制冷循环的基础上,本研究提出了一种无分凝器的氨水吸收式制冷循环系统。应用能量和质量守恒方程对循环中不同部件分别建立热力学模型,通过运用C++软件编程,对两种循环的循环特性进行了模拟计算。结果表明:在发生温度为150℃,冷却水进口温度32℃工况下,随蒸发温度的升高无分凝器循环的性能系数越来越接近常规循环,在空调工况下最为接近;反之,越来越偏离常规循环。

The Study on Ammonia- Water Absorption Refrigeration Cycle without Fractional Condenser

Based on conventional single stage ammonia-water absorption refrigeration cycle,a novel kind of ammonia-water absorption refrigeration cycle without fractional condenser is proposed in this study.The thermodynamic models of the components,based on the First Laws,have been assembled so as to quantify simulation the performance of the two cycles by Microsoft Visual C＋ ＋ programming.The results show that the COP of the cycle without fractional condenser is more and more close to conventional cycle,for generator temperature of 150℃ and cooling water inlet temperature of 32℃.They are closest at air conditioning condition.Conversely,they’re increasingly deviating from it.
