Mitsubishi Electric City Multi VRV Heat Recovery & CAHV Ecodan® System

Mitsubishi Electric City Multi VRV Heat Recovery & CAHV Ecodan® System — Independence Hub & Foundation Block, Brockenhurst College

The Challenge

Air Control were appointed by IDC Electrical & Mechanical Engineering to deliver the air-conditioning installation for the new Independence Hub & Foundation Block at Brockenhurst College in the New Forest. The project involved multiple teaching spaces requiring precise climate control to support student comfort and learning.

The challenge was to design and install a system capable of delivering simultaneous heating and cooling to all spaces while maintaining energy efficiency and ensuring quiet operation suitable for a learning environment. Close coordination with IDC and other trades was essential to ensure the installation aligned seamlessly with the building services strategy.

The Requirements

The client required a fully integrated solution that could provide heating and cooling simultaneously across multiple teaching areas. Acoustic performance was critical to avoid disruption during classes, and reliability was a key consideration for the college’s long-term operational needs.

The system also needed to provide high-temperature hot water for the building’s requirements, with a solution that could efficiently deliver large volumes of water while maintaining energy efficiency and sustainability.

All indoor units were required to be discreetly installed, maintaining the clean aesthetics of the teaching block, and centralised control for monitoring and zoning was a priority.

The Solution

Under the direction of Tom Luff, Senior Contracts Manager at Air Control, the team designed and installed a Mitsubishi Electric City Multi VRV heat recovery system, supplying all teaching spaces with simultaneous heating and cooling. All indoor units were 4-way ceiling cassettes, providing quiet, even air distribution while remaining discreet within the classrooms and communal areas.

In addition, Air Control supplied and commissioned a Mitsubishi Electric CAHV Ecodan® Packaged Hot Water Heat Pump system. The monoblock air-condensing outdoor unit produces very high volumes of high-temperature hot water, providing efficient and sustainable hot water supply for the building’s requirements. This system integrates seamlessly with the VRV installation, delivering a fully coordinated mechanical services solution.

Centralised control of the VRV and hot water systems is provided via Mitsubishi Electric’s management interface, allowing the college’s facilities staff to monitor and adjust all zones and hot water operation with ease. The installation was closely coordinated with IDC Electrical & Mechanical Engineering and other trades, ensuring smooth integration with the building services programme.

The Result

The completed installation delivers precise, energy-efficient climate control and high-temperature hot water across the Independence Hub & Foundation Block. Classrooms and teaching spaces benefit from quiet, evenly distributed heating and cooling, while the CAHV Ecodan® system provides reliable, high-volume hot water for the facility.

“Air Control delivered an exceptional solution for the Independence Hub & Foundation Block at Brockenhurst College. Tom Luff and his team fitted seamlessly into the project, working closely alongside our engineers throughout every stage. Over the course of the installation, the Air Control team and ours have become trusted colleagues and friends, which really emphasises the strength of their collaborative approach. The Mitsubishi Electric City Multi VRV and CAHV Ecodan® systems provide reliable, energy-efficient heating, cooling, and hot water. The installation ran smoothly alongside our wider M&E works, and their professionalism, technical expertise, and commitment to teamwork made them an invaluable partner on this project. We have worked with Air Control on many schemes and this project was another excellent example of their ability to deliver high-quality solutions while fostering a positive working environment.”
