An air handling unit (AHU) is the key component of an air conditioning system. It takes in outdoor or ventilated air, removes particles and dust, controls temperature and humidity levels, and supplies conditioned air via ducts. Inside an AHU casing are water cooling/heating coils, reheating coils, a humidifier, an air filter, and blower.

Apr 02, 2019 The latter creates higher pressure ratios than a centrifugal fan can achieve. This type of fan is typically attached to a system of ducts or tubes. This increases pressure, creating high-pressure airflow. Centrifugal fans usually have lower flow rates, move lesser volumes of air, and have steadier flow than axial fans.

Monitoring and Control of Cooling Water Equipment. An open recirculating cooling system uses the same water repeatedly to cool process equipment. Heat absorbed from the process must be dissipated to allow reuse of the water. Cooling towers, spray ponds, and evaporative condensers are used for this purpose.

The closed recirculating cooling water system evolved from methods used for the cooling of early engine designs. In a closed system, water circulates in a closed cycle and is subjected to alternate cooling and heating without air contact. Heat, absorbed by the water in the closed system, is normally transferred by a water-to-water exchanger to ...
