Educational Facility Air Conditioning Solutions

Daikin Air Conditioning Variable Refrigerant Volume (VRV) solutions with fresh air processing for heating, cooling and indoor air quality treatment (VRV AHU and Rooftop package units with economiser cycle) are generally used for education facilities.

1. Daikin VRV system is a multi-split type air conditioner (one outdoor unit with multiple indoor units) for commercial buildings that uses variable refrigerant flow control developed by Daikin to provide customers with the ability to maintain individual zone control in each room and floor of a building.

VRV indoor units that are generally used:

  • Highwalls (wall mounted)
  • Ducted Units (ceiling concealed) — complete with inbuilt drain pumps
  • Cassettes (ceiling mounted) — Roundflow cassettes with sensing panel or compact cassettes (600 x 600mm fully flat)
  • Under-ceiling (ceiling suspended)
  • Outdoor Air Processing unit (ceiling concealed)

2. VRV AHU (Air handling unit) is a system that pre-conditions outdoor air for ventilation purposes as required by the Building code and reduces operational load of air conditioning system. It consists of VRV outdoor units and air handling unit (filters, heat exchangers, dampers, fans in a framed casing) designed based on the client’s requirements.

3. Rooftop package unit is a system that contains all the components in one concise unit and provide conditioned air for large open space applications. This system can be also paired with Economiser kit that allows modulations of outdoor air and return air mixture for even further reduction of total operational load of air conditioning systems. It usually serves for bigger spaces like gyms or assemblies.

Education pack can also include:

  • Interfaces for opening window
  • Temperature setback
  • After hours use and scheduling
  • Central remote controller
  • Web access for off-site control (optional)
  • Bacnet interface (optional)
  • Energy monitoring (optional)

Wifi capabilities vary and are individual to each project and application

VRV outdoor units are recommended to installed outdoors to keep free air circulation around them and prevent overheating/short cycling. All coils have Blue fin anti-corrosion coating.

Package units are designed to be installed outdoors with its standard corrosion treatment and insulation. AHUs can be installed not only indoors but also outdoors with optional corrosion treatment and certain insulation thickness.

Limitations on Use
  • Certain connection ratio and max piping length rules between VRV outdoor unit and indoor units/AHU should be considered and met
  • Systems should not be used in corrosive indoor environments and high humidity applications (e.g. swimming pools)
  • For corrosive outdoor environments, additional treatment is required such as Blygold
  • Outdoor VRV units are not recommended to install in enclosed spaces unless required air intake volume and exhaust provided to and from the space. 
  • Refrigerant concentration compliance with AS/NZS 5149.1 & 5149.3 to be considered if VRV systems (R410A) used. Daikin offer an assistance with refrigerant concentration compliance volumes and mitigation methods on project basis
  • Daikin systems are designed for human comfort only — contact the Daikin team to discuss other applications
  • Please contact Daikin for full information
Statement of Building Code Compliance
  • Full range of Daikin products have been tested and registered in accordance with MEPS requirements (Minimum Energy Performance Standards)
  • Refrigerant leak detectors can be provided by Daikin with VRV systems to comply to standard AS/NZS 5149.1 and 5149.3

Other Performance Attributes
  • The VRV solution comes with the option of VRT smart technology. This technology allows the fluctuation of the refrigerant temperature. This provides better thermal comfort of the supply air temperature provided to the occupants and results in energy savings.
  • Blygold Coatings (on request)will prolong the life of the outdoor unit coupled with a maintenance plan.
  • Daikin is able to provide in-house modelling of airflow and temperature distribution in the installation spaces (CFD analysis) for their VRV for their VRV and Chilled water systems to ensure plant spaces are accurately designed to accommodate Daikin systems. This analysis will also give an indication if the units will be short cycling, creating inefficiencies in the operation.
  • Refrigerant leak detectors can be provided by Daikin with these VRV systems to comply to standard AS/NZS 5149.1 and 5149.3


  • Extended warranty to 7 years for MOE specific requirements 
  • Included Daikin Gold Health check pack for 7 years  to provide continued long term optimisation
