建筑凹槽中室外机安装条件对散热影响的实验研究

Experimental study on the effect of the outdoor unit installation conditions on the heat dissipation in the building groove

以焓差实验室为平台,以建筑凹槽内某型号室外机为研究对象,通过实验研究分体式空调室外机在不同安装位置和不同凹槽封闭百叶形式下的周围热环境及空调器的EER.实验结果表明:该型号室外机和墙体之间的间距应大于80 mm,随着两者间距的增大,空调器的散热量、制冷量和EER也随之升高;室外机排风扇距百叶300 mm左右时,系统运行状况最佳;百叶开度为30°左右时,空调散热效果最好,同时随着百叶间距的增大,空调散热效果增强.

This study was based on the enthalpy difference lab, with a certain type of outdoor machine in the building groove as the research object, through the experimental study the thermal environment surrounding outdoor machine and the EER in different locations and the different louver form in the groove. The experimental results show that the distance between the certain type of outdoor machine and the wall should be more than 80 mm, with the increase of the distance, quantity of heat, air conditioner refrigerating capacity and EER was increased. When the outdoor machine fan from the shutter is about 300 mm, the running condition of the system is best. When the shutter opening is 30°, the cooling effect air conditioning is best. At the same time with the increase of the louver spacing, the heat dissipation air conditioning is greatly enhanced.
