HVAC:
The basic air handling system consists of horizontal draw - through type air handling units with replaceable media filter banks, chilled water cooling coils, air distribution devices and constant air volume (CAV) fan-powered terminal devices. Heating for exterior zones is provided by hot water heating coils mounted in the CAV fan-powered terminal devices. Individual room thermostats - which are located in every CAV zone - control each terminal device. Each office floor is separated into a particular number of air conditioning zones, each served by a separate CAV fan- powered terminal device. The number of temperature zones per floor varies according to floor size; this system has the capability to provide a tenant with additional zones by adding or rearranging the fan-powered devices on that floor. There are 3 Trane Centravac centrifugal refrigeration machines, two 600-ton units and one 300-ton unit provide the air handlers with chilled water. Temperatures and pressures are controlled through the Building Management System (BMS). Condenser water is available at the riser in each air handling unit room for the tenant’s use.
