EC/DC MOTOR rotor permanent magnet lamination stackHall-effect sensorbearing system winding commutation electronics 7. Why the shift to EC/DC motor technology? To use less energy. Current building regulations require that that the specific fan power, Watts per Litre per second, for a FCU does not exceed 0.6 W(L/S). Most design specifications are looking for this to be 0.4 W(L/S) or less. Energy costs have soared taking this further up the agenda. To continue to give designers a choice. AC motors are inefficient and use to much energy. Without the introduction of energy efficient EC/DC technology designers would have to look at using alternative systems. 8. What are the benefits of using EC/DC? Use less energy50% reduction compared to ACCreate Less HeatReduced heat pick up and, Therefore, overall cooling requirement . Very useful in something that provides coolingInfinitely VariableFan speed is set via a 2 10 volt DC signal providing a much greater level of control and flexibility.Longer LifeCooler running, sealed for life bearings and casings make the EC/DC motor capable of lasting twice that of its AC counterpart. 90,000 Hrs.And Further Operational Benefits 9.

The first ETL listed FCU controller and strategy! Being on the Energy Technology List (ETL) means a business can take advantage of the Enhanced Capital Allowance Scheme (ECA). The ECA scheme allows businesses to claim 100% first year capital allowance on investments on ETL listed energy saving equipment. If a business spent 1000 the standard capital allowance would be approx. 41.50. The ECA would be worth a 230 one off tax relief in the first year! 39.

Basic Energy Monitoring Heath Check - Dirty FilterHeath Check - Fan FailureThe unit monitors the power consumption for a certain air volume on its curve after activation each day.If a drop in power consumption results in an alarmStandby Sentinel When fans are not required all non-essential controls elements are powered down minimising consumption.Basic Energy Monitoring The controller monitors the power consumption of the unit and reports it to an AV in watts 47. Control Strategy Uses an energy saving Variable Air Volume strategy. With an increase in cooling demand the first call is too raise the water flow rate. At a given point the Airflow starts to increase to provide more cooling. If the supply air temperature from the FCU approaches the minimum set value the air volume will be raised to offset this. All parameters are adjustable on a global or individual basis. 48. 100 %Air24 CSupply TempTypical With 6/12 Water80 %22 C 20 C60 %Air18 CSupply Volume16 C40 %14 C 20 % 12 C 0%Water10 CFlow Rate0%25 %50 %Space Load kW75 %100% 49. 100 %Air24 CSupply TempTypical With 14/17 Water80 %22 C 20 C60 %Air18 CSupply Volume16 C40 %14 C 20 % 12 C 0%Water10 CFlow Rate0%25 %50 %Space Load kW75 %100% 50.

What checks are done at the end of the line? FansAll fans are enabled and checked that they run from signal provided by the controller.ActuatorsValve actuators are fully functioned through the Delta Controller.Temperature SensorsA routine is run to normalize the temperature readings from the four sensors to remove potential measurement errors.TriacsAll the Triac outputs are checked for function, including those that are not connected.Comms CheckVia a laptop, communication with the controller is established to ensure it functions correctly. 56. Matrix - Environmental Commissioning Verifies kW cooling or heating output remotely. Accomplished by running a third of units in cooling and the rest in heating. Results are logged in a routine that runs from a Laptop. Results are corrected for differences between test conditions and design. FCU are selected to deliver cooling and heating. Matrix gives you the Ability to site verify this. 57. Matrix Engineering Tool Supplied on a NetBook to every Matrix project. Commissioning Tool to check operation, adjust operational parameters on a single or, via BMS, multiple Fan Coils. Can connect to the FCU via wireless network if appropriate access points are installed. This software has been developed over many years and is tailored to the Matrix range of Fan Coil Units. 58.
