摘要

本文以焓差实验室为平台，以住宅建筑凹槽内的两台某型号分体式空调室外机的安装条件为研究对象，研究三种室外机安装条件对周围热环境、空调器EER和凹槽面积的影响。凹槽内室外机的三种安装条件分别为同一平面相互垂直安装（两室外机在同一高度，室外机长度延长线互相垂直相交）、同一平面左右水平安装（两室外机在同一高度，室外机长度延长线共线）及沿外墙上下垂直安装（不同高度，室外机高度延长线共线）。实验结果表明：该型号两台室外机同一平面垂直安装时，建议水平间距(平行于外墙)d1≥650 mm，小于此间距时，距百叶较远的室外机运行环境恶劣，回风温度高于正常运行温度45 ℃；垂直间距（垂直于外墙）d2选择300 mm左右，继续增大则回风温度上升；当凹槽内两台室外机间不具备水平安装条件，但满足水平、垂直间距大于650 mm×300 mm空间要求时，建议采用平面垂直安装方式。水平安装时，回风效果较好，但考虑凹槽占用面积大，且水平间距d1﹥70 mm后，回风温度和EER都趋于平稳，故最佳间距为70 mm。上下垂直安装时，凹槽占地面积小于水平安装方式和平面垂直安装方式，回风效果明显优于平面垂直安装方式，最低回风温度甚至低于水平安装方式，最佳间距为150 mm。

Abstract

The installation conditions of two outdoor units were examined experimentally in an enthalpy-potential laboratory platform in this study. The influence of three installation conditions of outdoor unit on the surrounding thermal environment

air conditioner EER and groove area was studied. Three kinds of the outdoor unit installation conditions of groove were vertical installation of the same plane (two outdoor units at the same height

the length extension line of the outdoor unit perpendicular to each other and intersect)

horizontal installation of the same plane (two outdoor units at the same height

the length extension line of the outdoor unit is collinear) and parallel installation in height direction along the wall (two outdoor units at different heights

the height extension line of the outdoor unit is collinear)

respectively. For vertical installation in the same plane

the results suggest that horizontal distance (parallel to the exterior wall) d1 should not be less than 650 mm. Otherwise

a less favorable ambient environment will be obtained for the outdoor unit

and the return air temperature will be higher than normal

at 45 ℃. Further

the vertical distance (perpendicular to the exterior wall) d2 is recommended as 300 mm because bigger distance would cause the return air temperature to rise. If the slots do not match the installation conditions

but meet the horizontal and vertical spacing requirements (greater than 650 mm × 300 mm)

the perpendicular installation method to yield vertical installation in the same plane is recommended. The return air effect is good when plane installation is employed

and the considered grooves occupy a large area. Further

neither the return air temperature nor energy efficiency ratio (EER) increase obviously when d1 is more than 70 mm; thus

the optimal distance is 70 mm. When vertical installation perpendicular to the plane is employed

the groove area is less than those for horizontal installation and vertical installation in the same plane

and the return air effect is considerably better than that for vertical installation in the same plane. In addition

the lowest return air temperature is lower than that for plane installation; thus

the optimal distance is 150 mm.
