VAV control core parameters are therefore protected against unauthorized changes after production. Discharge and radiated sound power for a 700-cfm shut-off VAV box. These VAV boxes are designed to maintain the temperature for a desired level of occupant comfort by controlling the volume flow rate of the condi-tioned air in to an occupied zone in response to a duct. They are common in premium VAV systems and in applications such as conference rooms, cafeterias, etc. TSS系列出风口可选90度折边法兰;TCS&TVS标配90度折边法兰,更符合国内施. In response to varying loads in the ventilating zones, VAV damper's position changes in order to maintain required airflow. This is a ducted connection that provides air from an AHU. Low-temperature VAV Turndown. 5 million cycles. Traditional – It is basically the VAV box with the damper. Schematic of pressure-independent VAV box with hydronic reheat. 13-nom1 (0221) Single Duct VAV (TSS) Critical in today’s building environments is the need to place significant emphasis upon the occupants comfort and indoor acoustics.
