Packaged Multizone System

This system is best applicable to a limited number of fairly large zones, each with potentially different cooling or heating requirements or those with a high volume of people such as classrooms, meeting rooms in hotels and public spaces in commercial buildings. These applications have high ambient loads which are handled through the multizone unit. This system mixes cold and warm air together through zone mixing dampers located inside the unit. In response to zone thermostats, each zone is served by a single duct with variable temperature, constant volume airflow to control the comfort in the space. When combined with the chilled water system allows for part load control enhancing the overall system efficiency and saving energy. Some multizone systems (bypass type) mix neutral temperature return air with either cold or warm air to reduce the amount of reheat that is required. Packaged Multizone systems are often used due to the reduced cost associated with packaged equipment as compared with a built-u

This system requires the following components:
