Kellyville North Public School

North Kellyville Public School is a purpose-built learning environment, providing 40 brand new future-focused learning spaces and core facilities to accommodate for 1000 K-6 students.

The school opened its doors at the start of 2019, with pupils unknowingly welcomed and comforted by a Hitachi VRF system. January is well known to be one of the hottest months during the Great Australian Summer.

The school was initially built with limited air conditioning in specific locations and gas heating throughout. Then Jay Smith, Project Manager for Fredon Air Service received a request from the NSW Department of Education to design and construct a complete reverse cycle refrigerated HVAC system. Kellyvile North PS had just qualified for the Cooler Classrooms Program and the pressure was on to have the new heating ventilation and cooling system implemented prior to the new school year commencing.


A bit more about the Cooler Classrooms Program:

* A NSW government initiative focused on providing NSW schools with healthy and comfortable learning environments
* As part of the $500 million NSW government, eligible schools are those in areas with an average max January temperature of 30°C or more
* For more information, visit the Cooler Classrooms Official Website


A completely new approach was developed to meet the NSW Department of Education's requirements within tight deadlines.

Fredon Air had just 2 months to complete these works from design stage to final fit off and commissioning. They designed a VRF concept with help from Hitachi, that was eventually approved and signed off by all relevant parties.

"Greg Liolios (Hitachi Commercial Specialist) and James Perram (Hitachi Commercial Account Executive)
helped enormously with HVAC unit selection, on and off site technical support and fast-tracked deliveries.
Hitachi VRF's combination of quality, technology and technical support made it the perfect choice for this project.”
-- Jay Smith (Fredon Air)


Double ceilings, perforated and acoustic ceilings previously installed made installation very difficult as the suspended ceiling needed to be removed in order to run the piping and install the cassette units.

However, the project was completed on time. Hitachi’s Technical Manager, Siva Suppramaniam, from Temperzone was involved with the commissioning ensuring the site implementation and installation went smoothly. 


We would like to thank the following companies and individuals for their assistance throughout this project:

  • Jay Smith, Josh Harris & the team at Fredon HVAC
