Outside Air Treatment

Cutaway

Daikin has a range of Outside Air treatment solutions to meet the needs of your commercial air conditioning application.  Our Outside Air Processing units are able to pre-condition the outside air to deliver a fixed discharge air temperature to suit your needs.  The Outside Air Processing Unit can be operated as a single Heat Pump system or combined as part of a standard VRV Heat Pump or Heat Recovery solution. 

Daikin also offers Heat Reclaim Ventilator systems;  Our flagship VAM-GJ series are compact, energy efficient and can operate under a wide outdoor operating temperature range.  These units provide high enthalpy efficiency due to the greatly enhanced performance of the thin film element.  Furthermore, improved external static pressures offers greater design flexibility to the engineer.

Daikin Outdoor Air Processing Unit

Outdoor Air Processing Unit

With Daikin’s Outdoor Air Processing units, Outside Air treatment can be achieved with a single Heat Pump system.  The results are enhanced design flexibility and a significant reduction in total costs.

Daikin Outdoor Air Processing Units are available in three different capacities:

FXMQ125MFV1:  14kW, 300 l/s (rated condition)
FXMQ200MFV1:  22.4kW, 466 l/s (rated condition)
FXMQ250MFV1:  28kW, 583 l/s (rated condition)

Key features:

  • Daikin’s optimized scroll compressor designed for R-410A provides a quiet, reliable energy-efficient operation
  • Ability to set discharge air temperature from 13-25°C in Cooling and 18-30°C in Heating mode and provide the flexibility to integrate with a standard Daikin indoor unit or duct directly to the space
  • High ESP, up to 250Pa for greater ductwork design flexibility
  • Continuous operation from 19-43°C (Dry Bulb) in Cooling mode and -5-15°C (Dry Bulb) in Heating mode
  • Long pipe runs of up to 165m between indoor and outdoor unit
  • Possible to centrally manage the Outside Air Treatment unit by connecting it to the Daikin DIII Net for central control via an Intelligent Touch controller, Intelligent Touch Manager, or BACnet® gateways (Discharge temperature cannot be changed from the central control system)
 

Heat Reclaim Ventilator (VAM) series

Daikin Heat Reclaim Ventilators are designed to integrate with your air conditioner to create a high quality interior environment and reduce your air conditioning load by pre-treating the outside air with waste heat recovered from extracted air leaving the conditioned space.   Daikin's VAM series provides high enthalpy efficiencies, improved ESP for greater installation flexibility and night time free-cooling operations to further enhance the energy efficiency of the system.  

Daikin Heat Reclaim Ventilators are available in nine different models, with airflows ranging from 41 to 555 l/s.  For more details, contact your Daikin representative or download the brochure.

Key Features:

  • High temperature exchange and enthalpy exchange efficiencies due to the greatly enhanced performance of the thin film element
  • Wide operating range from -15-50°C (Dry Bulb)
  • Unique functions such as independent operation, interlock with other HVAC systems and Automatic Night Purge to reduce cooling load and improve energy efficiency
  • Interlock simultaneous operation with VRV indoor units through a single controller
  • Auto mode switches the ventilation mode (from Total Heat Exchange to Bypass mode) according to the operating status of the air conditioning system
  • Pre-cooling/heating control function to delay the start of ventilation during air conditioner start-up for improved energy efficiency
  • Night time free cooling mode to reduce the cooling load when the air conditioners are turned on in the morning
  • Filter sign and display reset notifies when filter changes are required
  • Sound levels as low as 21 dB(A) for noise sensitive locations (operating under low fan speed)
