Mitsubishi Electric’s City Multi VRF (Variable Refrigerant Flow) is a premium HVAC solution for any building in need of a specified, long-lasting and reliable HVAC system. It is the world’s first and only 2-pipe system that offers simultaneous heating and cooling. City Multi is best used for ducted or ductless buildings, commercial buildings of any size, spaces with specified area needs, condominium buildings, residential buildings and server rooms. In order to provide high levels of comfort and efficiency, City Multi has been engineered to incorporate many leading edge HVAC technologies including:

  • Variable Refrigerant Flow (VRF) technology that moves the eco-friendly R410A through 2 refrigerant pipes in adjusted levels to meet exact load requirements
  • Simultaneous heating and cooling throughout any building
  • Quiet indoor operation as low as 22dB(A)
  • Voltage options of 208V, 460V, and 575V
  • Indoor handling units in multiple configurations to suit the needs of each space
  • Advanced Lossnay Energy Recovery Ventilators (ERV) for optimized indoor air quality
  • Hydra-Dan energy conversion systems that significantly reduce CO2 emissions and operating costs

Features & Benefits

VCSi Technology
At the heart of Mitsubishi Electric’s Mr.Slim™ technology is Variable Compressor Speed Inverter (VCSi) technology. As opposed to conventional systems that inefficiently start with a surge and stay on at a maximum fixed speed, the VCSi technology automatically adjusts the system’s capacity to match your home’s moment to moment heating and cooling needs, thus saving you from the higher bills of a conventional system that runs at full speed even when demand is low.

VRF Technology
Variable Refrigerant Flow (VRF) technology is the brains behind the City Multi multi-split system. It ensures that the exact amount of refrigerant is circulated in the 2-pipe system in order to transfer heat between the indoor and outdoor units to meet the specific needs of each particular zone. Unlike most chiller systems, there is no refrigerant-to-water heat loss. Unlike most air ducted systems, there is no heat loss through lengthy metal ducts. VRF enables City Multi to adjust dynamically to meet actual load requirements, meaning no unnecessary waste in energy or operating expenses.

Hyper Heat at -30°C
City Multi’s patent-pending Hyper Heating Inverter (H2i) technology makes it one of few heat pumps that provide ultimate, energy-efficient room comfort when outdoor temperatures drop to -30 °C.

Air Source or Water Source Heat Pump
City Multi can be operated as either an air source or water source heat pump. In buildings where there is limited exterior access or simply for even greater energy efficiency, City Multi simply taps into a building’s existing water loop to provide highly efficient year round heat transfers.

Hydra-Dan Booster
City Multi, Hydra-Dan Booster and HEX units combine to convert recovered heat energy into hot water for sanitary use or hydronic radiant heating and cooling applications. Use City Multi and reduce your CO2 emissions while drastically reducing your operating costs.

Simultaneous Heating and Cooling
City Multi is the world’s first and only 2-pipe system that offers simultaneous heating and cooling using heat recovery. This heat recovery occurs via a branch circuit controller (BC Controller) which redistributes temperatures across zones while bypassing the compressor unit and thereby saving energy.

Zone Control
City Multi’s multi-zone Variable Refrigerant Flow (VRF) technology saves energy and allows you to program each room to its own temperature, satisfying any buildings diverse needs.

Environmentally Friendly
Using industry leading technologies like VRF, H2iTM, zone control systems and environmentally friendly refrigerant R410-A, City Multi ensures only the necessary amount of energy in consumed, depending on the actual load of each building on an ongoing basis.

Mitsubishi Electric City Multi systems use ozone friendly and non-CFC R-410A refrigerant, allowing you to feel cool while staying green.

Reduces Installation Time and Costs
With compact indoor and outdoor units designed for easy ductless installation, and control circuits and remote controllers that are proprietary to City Multi through a non-polar 2-wire M-Net communication bus, City Multi is designed to minimize installation time and costs.
