Large space for air conditioning can be implemented on a single piece of equipment for heating, cooling, ventilation and other features, a machine suitable for space at 5-30 meters tall, the products are widely used in industrial plants, warehouses, fans and locomotive maintenance logistics center, a large gymnasium, exhibition halls, auto 4S shops, supermarkets and other large space places. Products with low noise, large air volume, long range, uniform air distribution, easy to install, energy efficient air circulation heating operation to meet the tall space. Large space for air conditioning air distribution device will send the hot air evenly distributed from top to bottom throughout the space, eliminating bad indoor temperature layers. Air distribution feeders regulate gas flow rate and air supply equipment installed in accordance with the height and angle of heating, cooling and other different conditions, without the use of larger air flow temperature requirements that can achieve a sense of calm within the work area, the staff in the space feel warm and comfortable. Features: 1: repeated cycles of air to reduce the temperature gradient; 2: no hair, comfort higher; 3: You can achieve centralized control and individual control, easy to operate; 4: indoor conditions can be easily converted in accordance with various operating modes ; 5: Installation on the ceiling, you can make the job of the space bigger, nor will the workshop machinery, lighting and other internal facilities produce any hindrance. 6: In order to exclude condensate produced during cooling, the installation of the condensate flap; 7: no need to install air duct and the return air duct
