Abstract

In this study, a mathematical model of the dual suction compressor which can be applied to the household temperature and humidity independent control air conditioning system was established. The parameters of R410A were calculated with the help of REFPROP. The power consumptions of the dual suction compressor at different frequencies were calculated at different evaporation and condensing temperatures. Comparing with the experimental data, relative errors within \(\pm10\)% between the simulated and experimental values of compressor power consumption occurred under various conditions, suggesting that the accuracy of the established energy consumption model met the requirements of engineering application. With the established model, the influence of different evaporation and condensing temperatures on the compressor power consumption and energy efficiency were simulated. The results showed that when keeping the evaporation temperature and condensing temperature of the LT side as a constant, the compressor power consumption decreased by 3.2% with each 1°C increment of the average evaporation temperature of the HT side. On the other hand, when the HT side evaporation temperature and condensing temperature was maintained as a constant, increased by 10% and the compressor power consumption decreased by 1.7% with each 1°C increment of the average LT side evaporation temperature. The verified model can be applied to guide the optimization of evaporation and condensing temperatures in the future practical application of dual suction compressor in temperature and humidity independent control air conditioning system.

新型双吸入式压缩机能耗模型的建立与应用

摘要在本研究中，建立了一个可应用于家用温湿度独立控制空调系统的双吸气压缩机数学模型。借助 REFPROP 计算了 R410A 的参数。在不同的蒸发和冷凝温度下，计算了不同频率下双吸气压缩机的功率消耗。与实验数据相比，在各种条件下，压缩机能耗的模拟值与实验值的相对误差都在 \(\pm10\)% 以内，这表明所建立的能耗模型的准确性符合工程应用的要求。利用建立的模型，模拟了不同蒸发和冷凝温度对压缩机能耗和能效的影响。结果表明，当低温侧的蒸发温度和冷凝温度保持不变时，高温侧的平均蒸发温度每升高 1°C，压缩机的耗电量就会降低 3.2%。另一方面，当 HT 侧蒸发温度和冷凝温度保持不变时，LT 侧平均蒸发温度每升高 1°C，压缩机耗电量增加 10%，压缩机耗电量减少 1.7%。验证后的模型可用于指导今后温湿度独立控制空调系统中双吸气压缩机蒸发和冷凝温度的优化。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
