VRF
VRF system City Multi VRF from Mitsubishi Electric
ProduktreiheThe modern air conditioning and heating solution for complex buildings
Our City Multi VRF system offers innovative system solutions that already meet the future requirements of the industry. The City Multi VRF system ensures efficient building air conditioning, enables individual temperature control, and offers versatile customization options. Thanks to inverter technology, the refrigerant flow can be individually adjusted to the respective requirements of individual rooms or areas. This enables precise temperature control in different zones and rooms.
How do VRF systems work?
FunctionVRF technology explained simply
VRF systems are an efficient, sustainable, and future-proof solution used in buildings for heating, cooling, ventilation, and hot water production. The abbreviation VRF stands for "Variable Refrigerant Flow." This means that VRF technology uses a flexible refrigerant system that circulates between a central outdoor unit and several indoor units. This enables individual zone control, whereby different areas of a building can be cooled and/or heated independently of each other.
VRF systems continuously adjust cooling or heating output to current demand, consuming only as much energy as is actually needed. Inverters regulate compressor output to monitor temperature precisely. The BC controller (Building Controller) enables central control, monitoring, and remote maintenance of the entire system. VRF technology therefore ensures more precise temperature control, individual zone control, increased energy efficiency, and seamless integration into building automation systems. Compared to conventional air conditioning systems, VRF technology can offer tailor-made solutions for a wide range of applications in buildings and is therefore often the preferred choice in modern, complex buildings.

Areas of application where City Multi VRF demonstrates its strengths:
1. Commercial buildings and office complexes:
City Multi VRF is ideal for office buildings and commercial facilities where individual zone control and energy efficiency are crucial. Different office floors or business areas can be cooled or heated independently of each other to maximize employee comfort and minimize energy consumption.
2. Hotels and accommodations:
In the hotel industry, City Multi VRF enables precise control of the room temperature in guest rooms, guaranteeing a pleasant stay. At the same time, the system can provide optimal air conditioning in common areas.
3. Educational institutions:
Schools, universities, and educational institutions benefit from the flexible zone control of City Multi VRF. Different classrooms and areas can be individually adjusted to create a comfortable learning environment.
4. Healthcare:
Hospitals and medical facilities have demanding requirements for indoor air quality and temperature control. City Multi VRF can meet these requirements while offering energy-efficient solutions.
5. Retail:
In retail, City Multi VRF systems can optimize air conditioning in sales rooms to ensure customer comfort while reducing energy costs.
6. Residential buildings:
City Multi VRF is also suitable for residential complexes. Residents can individually adjust the temperature in their apartments, while the system operates efficiently overall.
7. Restaurants and catering:
City Multi VRF technology offers restaurants the flexibility to efficiently air-condition different areas such as dining areas and kitchens.
Advantages of City Multi VRF systems
Climate and heating solutions for demanding projectsCity Multi VRF enables individual zone control, allowing each room or zone of the building to be cooled or heated independently. This not only contributes to increased personal comfort, but also saves energy, as unused areas are not excessively air-conditioned.
Compared to traditional air conditioning systems with central ventilation ducts, City Multi VRF requires less complex installation. The wiring and piping are simpler, which reduces installation time. In addition, less space is required for ventilation shafts or ducts.
Intelligent control and adjustment of energy requirements in real time lead to a reduction in operating costs. Energy consumption is optimized by using energy efficiently and avoiding overload peaks.
City Multi VRF is suitable for both new buildings and the modernization of existing buildings. Its flexible installation options and retrofitting capabilities make it the ideal solution for a variety of construction projects.
City Multi VRF indoor units are known for their quiet operation. This makes them ideal for environments where quiet and comfort are of the utmost importance, such as hotel rooms, hospital rooms, or conference rooms.
The energy efficiency of City Multi VRF reduces CO2 emissions compared to conventional air conditioning systems. This helps to minimize environmental impact and reduce the ecological footprint of buildings.
The integration of City Multi VRF into building technology enables comprehensive control and monitoring of energy management, load management, security, room occupancy, and more. This takes comfort, energy efficiency, and security to a whole new level.
The central control unit of City Multi VRF ensures easy monitoring and maintenance of the system. Errors and problems can be detected and solved at an early stage, maximizing uptime and efficiency.
R2 series: Simultaneous cooling and heating with heat recovery
R2 seriesVersatile climate control, optimized for the whole year
The R2 series from Mitsubishi Electric is the only heat recovery system in the world that enables simultaneous cooling and heating with just two pipes. Heat energy extracted from a room during cooling operation can be used to heat other rooms or to heat water. Another efficiency bonus: the use of a special booster unit also enables hot water to be heated to up to 70 °C in the same system. The central component of every City Multi VRF R2 system is the BC controller, which acts as a refrigerant distributor and, together with the outdoor unit, forms a refrigeration and control unit for heat recovery.
Key features of the R2 series:
- Each indoor unit can be used individually in cooling or heating mode.
- Energy generated is reused in the process
- Fewer connection points and thus reduced potential for leakage
- No downtime when changing the operating mode of the outdoor unit, ensuring stable operation of the indoor units
- Heat recovery with a system COP above 8
Y series: Heating or cooling – always energy efficient
Y seriesSmart efficiency, personalized comfort
The Y-series is a flexible and powerful air conditioning system that combines maximum climate comfort with maximum energy efficiency.Your 2-pipe system for alternating cooling or heating operation connects up to 50 indoor units of various designs in a single refrigeration circuit. A wide selection of indoor units, extensive control options, and many other strengths make the Y-Series a particularly powerful solution for applications ranging from hotels to open-plan offices.
Key features of the Y series:
- High seasonal energy efficiency
- Individual temperature control on each indoor unit within the respective operating mode
- Zubadan technology in VRF outdoor units for 100% performance at outdoor temperatures as low as –15 °C
- Up to 50 indoor units can be integrated into a single refrigeration circuit
- Space-saving installation thanks to compact dimensions
