摘要
Abstract
A super high-rise building in Guangzhou is taken as the research object to analyze the heat dissipation performance of the air-cooled variable refrigerant flow system outdoor unit set up in the recessed restricted space of the building through numerical simulation.The study simulates three typical platform configurations(platform 1-E,2-W,2-S),from analyzing the return air temperature,local heat accumulation effect and the influence of external building components on airflow organization.Through the simulation of the building wind field and the equipment heat dissipation model,the heat dissipation effect of different outdoor unit platforms is analyzed and optimization suggestions are made.The results show that the reasonable design of the depth of the outdoor unit platform and the optimization of the fresh air make-up path,as well as the selection of equipment with a high shutdown protection temperature,can effectively improve the heat dissipation effect and ensure the reliable operation of the air conditioning system.关键词
