LINDINVENT DCV-FLb Airflow Unit 2-Stage Controller

Introduction

• DCV-FLb is part of Lindinvent’s series of smart and installation-efficient dampers for protective ventilation or on-demand control of indoor climate at workplaces.

FUNCTION

DCV-FLb consists of a damper with a measuring unit, a damper motor, and a regulator. The device can quickly and safely switch between a fixed normal flow (workflow) and a lower minimum flow (standby mode).

• Suitable for controlling equipment where the air ow does not need a continuous demand control (it could be in a kitchen where a switch should trigger the higher or lower air ow)
• Timer function which after a set time restores the airflow to the normal flow (working mode)
• Connection for user panel FLOCHECK F with button selection to be able to switch between working modes
• Reports measured airflow via CAN
• Connected via Node-ID to a local area network (CAN) for stable communication with other controllers
• Gateway NCE is connected to the local network for access and communication via a parent system
• The controller is programmable and its parameters can be read or set locally via handset or centrally over the network
• Equipped with Bluetooth® for communication via mobile application LINDINSIDE

Circular or Rectangular

The circular version (Ø100-500 mm) is delivered as a complete module with the constituent parts connected and ready for installation as a unit. DCV-FLb Rectangular is ordered as a set of parts to be assembled on-site. DCV-FLb in circular design is available in the database for MagiCad. DCV-FLb rectangular drawn as damper JSPM and measuring unit SMRD.

flow measurement and airflow

• Circular & Rectangular
• Measurement range: 0.5 – 6.0 m/s
• Maximum range: 0.2 – 7.0 m/s
• Accuracy: ± 5 % or at least ± x l/s
• (where x = The channel area in dm2)
• Airfl ow calculation (q): q = k * √ Δp [l/s]

k-factor Rectangular

• Calculate k as follows:
• k = 749 * A where A = Width(W) * Height(H) where measures W and H in meters
• An example: SMRD 500×200 = 749 * 0,5 * 0,2 = 74,9

k-factor Cirkular

• The k-factor can be read from the damper or the table in the product description for SPMF.

Flow range per damper size DCV-FLb Circular

• Flow range [l/s] for each size of SPMF.
