lindab | comfort Lindab Pascal - Simplified VAV solution with full potential. . .

lindab | comfort Constant pressure solution Solution based on constant pressure regulation • • • Active diffusers with built-in damper plate, which is controlled by a room regulator with 0 -10 V signal Exhaust air flow regulation by measuring airflow in supply duct Pressure regulation in supply distribution duct

lindab | comfort Constant pressure solution Exhaust balance with flow measurement – master/slave function Measuring unit has a minimum flow rate limit Measuring unit requires straight duct before the unit Addition of several supply to control one exhaust is difficult FRU/VRU settings must be done special from factory Extra components for flow measurement

lindab | comfort Constant pressure solution Active diffusers Diffusers with high impulse even at low airflows Diffuser settings must be done individually from factory Not possible to put on stock Labelling with ID must be done for each room Airflow settings are based on theoretical calculated pressure (no airflow regulation) • • • Correct pressure = correct airflow Higher pressure = higher airflow Lower pressure = lower airflow

lindab | comfort Constant pressure solution Pressure regulation Areas with constant flow balanced with simple balancing damper Limited pressure allowance in diffuser Size of pressure zone not to big Difficult keeping constant pressure in all parts of a zone High demand on duct design Limited flexibility when reconstructed Exact placement of pressure sensor Higher energy consumption due to higher minimum pressure Fan optimizer only on zone dampers Extra components for pressure regulation

lindab | comfort Vision Our vision is: • Install a standard VAV system with room temperature regulation • Make settings of air flow in room regulator • Indicate which supply diffusers that affects the exhaust damper This is done by: • • Installing a motorized plenum box that can handle high pressure with low sound Installing a suitable diffuser that can handle 0 -100% airflow without the risk of draft Making sure the pressure in the system is not exceeding 200 Pa Measuring actual air flow regardless of pressure Setting all parameters in displays on Regula units Total air flow for supply diffusers is being added up and exhaust air flow is regulated The fan uses only necessary pressure for each diffuser

lindab | comfort Constant pressure solution • • • Active diffusers Constant pressure Measuring for exhaust • • • Active boxes Variable pressure Calculation for exhaust Pascal

lindab | comfort Pascal components Regula Master • • Standard hardware from Regin – known in the market Special designed software for Pascal One standard unit with three modes • • • Three basic functions in the system • Exhaust control • • Single Regula Master (SRM) Local Regula Master (LRM) Global Regula Master (GRM) • • • Summary of supply air volumes which affect the exhaust damper Summary of constant flows which affect the exhaust damper Factor for more/less exhaust than supply Fan optimizer • Secures that the most open damper is open to 85%. If the damper is more open, accelerate the fan – if less slow down Operating control • • Monitors damper behavior in the system Gives alert if a damper does not move over time All communication between Regula units with Exoline Communication to overall BMS via Exoline or via an OPC solution (BMS contractor)
