City Multi Indoor Units

Mitsubishi Electric commercial air conditioners can be integrated with building management systems (BMS) to enable centralised control, real-time monitoring, and automation of HVAC operations.

This integration helps optimise:

• Energy use
• Occupant comfort
• Sustainability goals
• Insights for long-term efficiency

Commercial air conditioners from Mitsubishi Electric are designed for new constructions and adaptive reuse projects, making them ideal for retrofitting older buildings. These systems’ versatile and space-efficient design allows for seamless integration into heritage-listed properties, office conversions, hotels, and other commercial spaces where traditional HVAC solutions may not be practical.

For heritage buildings like The Rocks Discovery Museum in Sydney, a City Multi PUHY air-cooled heat pump and PFFY floor console units were installed without drilling into sandstone walls. Instead, refrigeration piping and cables were routed through the mortar between sandstone blocks or existing penetrations, while overhead pipes were concealed beneath floorboards.

For adaptive reuse projects, such as the Abode Hotel in Woden, the City Multi VRF heat recovery system was selected to convert a 1970s government office into a modern, energy-efficient hotel. This system enabled simultaneous heating and cooling across different rooms, improving guest comfort while contributing to the hotel’s 4.5-star NABERS Energy rating. Unlike traditional HVAC systems, City Multi VRF operates with just two refrigerant pipes, reducing installation costs.

For similar projects, the flexible HVAC solutions from Mitsubishi Electric—including ceiling-concealed units, floor consoles, and heat recovery VRF systems—provide energy-efficient climate control without major structural modifications. Whether upgrading an outdated system or integrating air conditioning into a challenging floor plan, these systems offer proven solutions for older buildings and adaptive reuse developments.
