VAV FPMB with Central Station Air Handler with Chilled Water
This system is best suited for large zone applications. In the cooling mode this system uses a single duct with constant temperature air and modulates the airflow quantity to control the comfort in the space. In the heating mode the fan-powered mixing boxes recover ceiling plenum light heat, and along with optional supplemental heat, use this to help heat the perimeter spaces. The air handling units are equipped to modulate the airflow, and when combined with the chilled water system allows for part load control enhancing the overall system efficiency and saving energy. Fan-powered systems are often selected because they deliver higher air circulation rates through the space while retaining all the advantages of VAV systems.
