Features of design
Symmetrical laid out 4 ducts with 1118 mm in diameter and 38 m in length in the whole shopping area and design different air velocities according to different functional areas. For example, in refrigeration, cooling and freezer areas: In order not to break cold chain in these areas and airflow model was PM, end air velocity was limited to 0.1 m/s; In household appliance, daily necessaries, food areas: Selected PS airflow model and end air velocity was limited to 0.3 m/s since customer flow was not very large; In check-out areas: Selected EJ airflow model and end air velocity was limited to 0.5 m/s since customer flow was very large in these areas.
Features of application:
Uniform airflow with great comfort, easy to installation and cleaning and maintenance, energy-saving and economic
