Cooling Lab – Room AC & Fan Airflow Simulator

Place and aim multiple air conditioners and pedestal fans in a 3D room. Watch cool-air particles and a live floor heatmap reveal where the cooling actually reaches. Add furniture as obstacles, resize the room, switch AC louvers between fixed / horizontal / vertical swing, and fine-tune fan speed, yaw and pitch. A coverage score shows what percent of the floor is being cooled, and a “Suggest better spot” button helps you improve fan placement.
