| Popis: | How 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. |
