Air Handling Unit

The modular air handling unit (AHU) is at the core of the system. It is connected to a sustainable heating/cooling source such as a heat pump, solar panel or high efficiency boiler.

EC Fan Motor

A variable frequency direct drive (VFD), inverter, permanently lubricated, electronically commutated (EC) fan motor is housed within the AHU. The same motor is used for all three model sizes.

The fan motor uses less energy than standard motors.  It is brushless, does not generate excess heat and is cold to the touch.

The motor provides a wide range of speeds and only uses the amount of power needed to achieve the desired speed. It adjusts its speed to suit requirements.  It converts the single phase supply to a three phase for extra efficiency.

The constant fan option increases energy efficiency further.

WEG Inverter Drive

The digital display WEG inverter drive is a reliable and robust motor control.  It is housed within the air handling unit and provides many years of issue-free operation.

The WEG is sized to ensure increased reliability and higher efficiencies at peak load. It allows for minimum power consumption at reduced loads (<100w average for constant fan speed).

It allows the setting of minimum and maximum fan speeds. Fan speed is determined by the PSB circuit board. The PSB converts the pressure in the duct to a 0 - 10vdc output to control the VFD.

PSB Circuit Board with Pulse Wave Modulator

PSB Circuit Board

The PSB sends control signals to the heating/cooling source. When used with inverter heat pump air conditioning DX outdoor units, it is connected to an interface panel supplied by the heat pump manufacturer.

Pulse Wave Modulator

A pre-installed pulse wave modulator (PWM) speed controls the EC fan motor via the WEG inverter drive.

Return Air Box

The return air box is an optional component for the return air plenum, which is connected to the air handling unit (AHU). It is acoustically lined with half-inch sound absorbing insulation.

Take Off

The take-off connects the main plenum ductwork to the flexible mini ducts.

Plenum Duct

The air handling unit (AHU) is connected to a supply ductwork plenum. The plenum connects to small diameter, 3m long flexible ducts called mini ducts. The mini ducts terminate in discreet air outlets positioned discreetly in the walls, floors and ceilings.

Rough-in Boot

The rough-in boot is connected to the mini duct and is used to position the mini duct and the air outlet vent plate. The insulation and vapour barrier that is around the mini duct can also be used for the rough in boot.

Discreet Air Outlet

There are three types of air outlet, depending on the finish and style you require. These can be mixed and matched.

Air outlets are positioned discreetly in ‘out of traffic’ areas in walls, ceilings, floors and bulkheads.

The system’s method of air delivery constantly and gently circulates the air to maintain room comfort. This allows more options for outlet placement.

Flexible Mini Duct

The air handling unit is connected to the main ductwork plenum. The plenum connects to small flexible ducts called mini ducts. The mini ducts terminate in discreet air outlets positioned in ‘out of traffic’ areas in floors, walls and ceilings.

There are two sizes of mini duct, HE (72mm diameter) and HV (50mm diameter). The air flow from one HE duct is equal to two HV ducts of the same length.

Heating/Cooling Source

The Ingenious Air Small Duct System is connected to a heating/cooling source. This provides the heating and/or cooling. The type of heating/cooling source will depend on the services you want the system to perform.

Heating/cooling sources include:

  • Air to air heat pumps (refrigerant heat pumps)
  • Air to water heat pumps
  • Ground source heat pumps
  • High efficiency boilers (gas, oil fired, electric, bio-mass etc.)
  • Solar panels
  • Chilled water systems
  • Electric heater
  • District heating systems.

Connectors

There are five types of connectors:

  1. Tee
  2. Elbow
  3. End cap
  4. Straight
  5. Reducer

Keeping the number of connectors to a minimum gives best system performance.

Optional Modules

A choice of optional modules can be added to the air handling unit (AHU). These provide up to six functions to create your ideal indoor environment:

  • Cooling - refrigerant or chilled water
  • Heating
  • High specification air purification
  • Humidity control
  • Outside air ventilation
  • Mechanical heat recovery ventilation
