상품 소개

The single-duct VAV reheat terminal unit combines a round primary-air inlet, averaging flow sensor, modulating damper and rectangular discharge casing with an integral heating section. During cooling demand, the controller varies primary airflow between programmed minimum and maximum values. When the zone requires heat, airflow is held at the heating minimum while a hot-water valve or staged electric heater raises the discharge temperature. An acoustic liner and optional attenuator control regenerated noise, while coil access panels support inspection of the downstream heating section.

주요 기능

An averaging inlet sensor and matched controller maintain primary airflow as duct static pressure changes.

Hot-water or electric reheat adds sensible heat downstream of the control damper without a terminal fan.

Programmed cooling, ventilation and heating minimums allow airflow to follow the zone operating sequence.

Acoustic lining and optional discharge attenuator reduce radiated and air-path noise above occupied spaces.

고객 제품 관심사

A reheat terminal must preserve required ventilation airflow, prevent discharge overheating, control noise and keep the heating coil and controller accessible above the ceiling.

Reducing cooling airflow below the ventilation minimum compromises room air exchange.Separate programmed cooling and occupied minimums keep primary air above the required ventilation quantity.

Reheat energizes at too little airflow and produces excessive discharge temperature.Airflow proof and a defined heating minimum enable the coil or heater only when sufficient air passes through the box.

High inlet static pressure produces objectionable regenerated noise over the room.Correct inlet sizing, duct-pressure reset and acoustic attenuation limit velocity and throttling sound.

A leaking water coil valve causes simultaneous cooling and heating energy waste.A tight-closing modulating valve and discharge-air temperature monitoring expose unintended heat input.
