Optimization design of installation platform for outdoor units of residential air conditioners
摘要：
调查了重庆地区住宅空调室外机常见安装方式，按临空面数将其划分为5种类型。通过实验测试研究了各种安装方式对室外机进风温度（评估指标）的影响。结果表明，临空面数量越少，进风温度越高，热泵效率越低。在实验和模拟研究的基础上，提出了2种优化设计方案：在室外机出风口设置分隔进出风的分隔板；在室外机出风口设置引流管道。实验和CFD模拟结果表明，进出风分隔板可以显著降低进风温度，带有引流管道的设计可以使进风温度仅略高于环境空气温度，热泵性能得以改善。
Abstract：
Investigates the common installation methods of outdoor units of residential air conditioners in Chongqing, and divides them into five types according to the number of exposure surfaces. Studies the influence of various installation methods on the inlet air temperature (evaluation index) of outdoor units through experimental tests. The results show that the less the number of exposure surface, the higher the inlet air temperature and the lower the efficiency of the heat pump. On the basis of experiment and simulation research, proposes two kinds of optimal design schemes: 1) set up a partition board to separate the supply and exhaust air at the exhaust outlet of outdoor units, 2) set up an induced pipe at the exhaust outlet of outdoor units. The experimental and CFD simulation results show that the partition board can significantly reduce the inlet air temperature, and the design with an induced pipe can make the inlet air temperature slightly higher than the ambient air temperature, which improves the performance of the heat pump.
