Volume 146, 2016, Pages 350–358The 8th international cold climate HVAC ConferenceEdited By Lin Duanmu, Xiangli Li and Shuang Jiang Influence of Air-conditioning Outdoor Unit Arrangement Strategy on Energy Consumption ☆a b Available online 1 July 2016How to prevent the hot air entering the outdoor unit is thus critical for Split-type air conditioner (AC) operation temperature control. This investigation studied the influence of louver installation (angle and spacing) and outdoor AC unit arrangement (style and location) on the system ventilation using computational fluid dynamics (CFD) technique. With the louver spacing increasing and the distance between neighbouring outdoor AC units decreasing, the working temperature increases. Considering heat dissipation and protecting machines from rainwater, the optimum louver angle is 100 degrees.

The vertical arrangement for outdoor units is more beneficial to exhaust hot air than the horizontal arrangement. In conclusion, in order to reduce operation temperature while saving energy, the following design points are recommended:a.Vertical arrangement for outdoor units;b.Larger distance between neighbouring outdoor units;c.Smaller louver spacing;d.100 degrees for the louver angle.References[1][2]Optimum placement of condensing units of split-type air-conditioners by numerical simulation[3]Thermoeconomic analysis and optimization of residential split-type air conditioners[4]Influence of a depth of a recessed space to flow due to air-conditioner heat rejection[5]Effects of stacked condensers in a high-rise apartment building[6]Flow analysis of condenser cooling air delivery via building light well[7]Effect of building re-entrant shape on performance of air-cooled condensing units[8]Placement of condensing units of split-type air-conditioners at low-rise residences[9]Numerical heat transfer and fluid flow[10]Prediction of temperature rise near condensing units in the confined space of a high-rise building© 2016 The Author(s).
