Commercial Combined Sections AHU Air Handling Unit features and advantages introduction:
The surface cooler adopts the structure of four, six and eight rows of copper tubes and aluminum foil. The aluminum foil is in the form of double flanged corrugated edges. The large elbow heat exchanger reduces the welding elbow by 60%, which improves the heat exchange power. The mechanical expansion tube ensures the contact performance of the heat exchanger. The heat exchanger is divided into two types: fixed type and rotary type. Users can choose one according to their needs. The heat medium is steam or hot water.
This section is used for the connection of the transition section and the internal maintenance and lighting of the unit. Before the filtering section, there must be an intermediate section before and after the cooling section, heating section and muffler section.
Fresh air/exhaust section (also known as flat-top air split mixing section) This section of the box is equipped with a primary air return valve. The top of the box before and after the valve is equipped with an exhaust port and a fresh air port, and is equipped with a regulating valve. Its functions are: When there is a return fan, the supply air conditioner discharges part of the return air, so that the fresh air and the primary return air are mixed according to the required ratio; when the direct current system is adopted in the transition season, the primary return air valve should be closed, and the exhaust valve and fresh air valve should be fully opened.
