多联式空调系统APF性能仿真的模型开发与软件实现
Model development and software implementation for predicting APF of multi-split air conditioning system
摘要
Abstract
The energy efficiency evaluation index of multi-split air conditioner(VRF)system has been converted into the annual performance factor(APF).To improve the APF performance of VRF system,it is necessary to improve the design efficiency through computer simulation.Based on the component models and solving method of VRF system,this article proposes a correction method for low-temperature heating under unsteady conditions,using factors such as compressor frequency and indoor and outdoor fan wind speed to correct system performance parameters,and obtain the average value of system performance during the defrosting cycle.Based on modular framework design,a multi-split air conditioner APF performance simulation software has been developed.The accuracy of the software has been verified through experimental data,and the prediction errors of the software for the system capacity and power of a single APF condition are within 7%,and the prediction errors for the overall APF of the system are within 5%.The results show that the multi-split air conditioning system APF performance simulation software developed in this article has good accuracy and can meet the needs of system optimization.关键词
