HVFS series Series HVFS 1 HVFS terminal units with fan CONTENTS Description Versions and dimensions Technical data 2 3 8 2 Series HVFS HVFS terminal units with fan Description The HVFS terminal unit is a solution that fully adapts to installations in which it is desirable to retain the flexibility of a variable air volume (VAV) system, while also providing a constant air volume to specific areas (VAC). When the thermal demands in the conditioned space are highest, the flow rate supplied by the HVFS air terminal is 100% primary air, an action that is controlled by the volume control damper. The HVFS boxes include the following: - Double-inlet fan with built-in single-phase motor, with adjustable speed drive. - Differential pressure sensor at the primary air inlet. - Actuator-Belimo NMV-D2M volume control damper, at the primary air inlet. - Airtight volume control damper, manufactured of galvanized steel sheet, that runs at low pressure. - Return air inlet with acoustic silencer at inlet. - Fiberglass insulation with a thickness of 50 mm on the inner surface of the box enclosure. As the thermal needs of the conditioned space gradually decrease, the primary air intake to the air terminal also gradually decreases and the secondary air intake increases proportionally. The air flow supplied by the fan to the diffusers remains constant, whereas the temperature changes according to thermal demand. The HVFS boxes control the supply air temperature by varying the primary air intake (characteristic of a VAV system), while the supply flow to the rooms remain constant (characteristic of a VAC system). The HVFSW and HVFSE air terminals include a hot-water or electric coil, respectively, when necessary to combat negative loads (winter), e.g., perimeter loads or in the cases of prolonged shutdown of the installation. In these cases, the primary air intake is low, ensuring a minimal ventilation air supply. The HVFS terminal unit comes in 7 sizes, covering an air flow range of 300 to 6200 m3/h. The HVFS terminal units are serviced from the outside, with no need to remove the unit; the fan motor assembly may be removed through the lower panel, and the control elements from one side of the unit.
