摘　　要：以上海市临港新城的某高层住宅为例,利用Airpak软件,用CFD模拟的方法,探讨了设置于连廊内天井内侧向出风的空调室外机气流组织情况。得到结论:天井两侧室外机型号相同时,两侧出风口不对称,靠外一侧的出风口出风射流干涉另一侧出风射流,使其方向偏向内侧,两个出风射流易与进风口短路,使出风口靠内侧的室外机回风温度升高较大;连廊上的安全护栏为栏板时,散热条件与安全护栏为栏杆时相差较大,且栏板的位置对散热也有一定的影响。随内天井长度的减小,栏板对散热的影响逐渐减小。Taking a high-rise residence in Lingang New City in Shanghai as an example,using Airpak software and CFD simulation method,the airflow distribution of an air conditioner outdoor unit installed in a patio in a corridor with lateral air outlet is discussed.It is concluded that when the outdoor units on both sides of the patio are the same model,the air outlets on both sides are asymmetrical,and the air outlet jet on the outer side interferes with the air outlet jet on the other side,causing its direction to be tilted to the inner side.The two air outlet jets are easy to be short-circuited with the air inlet,and the return air temperature of the outdoor unit on the inner side of the air outlet increases greatly;When the safety guardrail on the corridor is a railing,the heat dissipation conditions are quite different from when the safety guardrail is a railing,and the position of the railing also has a certain impact on heat dissipation.As the length of the inner patio decreases,the impact of the railing on heat dissipation gradually decreases.
