Thermal Environment Analysis of Outdoor Units of Air Conditioners in the Wind Field Environment of a Building Cluster
When the air-conditioner is in operation,the heat dissipation of the external outdoor unit will be interfered by the complex wind field environment in the building cluser,which will in turn affect its operational efficiency.Taking the outdoor unit of the air conditioner arranged in the groove as the object,considering the change of the flow field inside the building cluster,the thermal environment of the frontal wind and the rear wind when the outdoor unit is running downward is studied,the thermal environment difference of the outdoor unit with the height and location of the building is analyzed,and the difference of heat dissipation of the outdoor unit in the windward building and the downwind building is emphasized.The result shows that the operating efficiency of air-conditioning outdoor units is strongly influenced by the wind field environment within the building cluster.In the frontal wind direction,the higher the wind speed,the worse the efficiency of the outdoor unit;the efficiency of the outdoor unit operating at building B in the downwind direction is even worse.In the back wind direction,the average inlet temperature of the outdoor unit at the downwind building A is relatively higher.
