Eco Changes

Mitsubishi Electric's multi-zone
HVAC system
cools and heats different rooms simultaneously.

Room temperatures differ even in the same building, according to the amount of sunlight that reaches into the room and the direction the windows face. In such offices, Mitsubishi Electric's City Multi R2-Series Variable Refrigerant Flow (VRF) System offers an ideal solution. In addition to controlling the entire building, the R2-Series simultaneously cools and heats different zones in the building. This means an optimum temperature can be set for each room according to the amount of sunlight it receives, the number of people who use the room, the number of electronic appliances that are used in the room, and other such specific conditions.

For example, you can set the system to provide cooling in machine rooms and west-facing rooms where temperatures tend to be high, and provide heating in offices that receive little sunlight or window-less conference rooms. Furthermore, the R2-Series uses just two pipes, something that no other manufacturer in the industry can do, to significantly save on pipe installations. There is no doubt the R2-Series is the perfect multi-zone HVAC system for future offices.

Flexible cooling and heating settings enable HVAC operations suited to the actual status of each room, such as room temperature and purpose.

City Multi R2-Series Two-pipe Simultaneous Cooling and Heating HVAC System

Mitsubishi Electric has developed a multi-zone HVAC system that provides simultaneous cooling and heating to satisfy customers who seek solutions to a large number of individual needs. By connecting the required number of indoor units to an R2-Series outdoor unit, each room can be cooled or heated as desired. Moreover, through the use of the Branch Circuit (BC) Controller, which is equipped with a gas-liquid separation function and a flow dividing function, differing phases of refrigerants are circulated between indoor units with differing demands, for effective energy recovery.

The industry's only two-pipe simultaneous cooling and heating system saves on materials and installation.

The industry's only* two-pipe simultaneous cooling and heating system has fewer pipe connections compared to the three-pipe system, and offers greater system stability. It also uses less copper pipes and insulation, and contributes to the sustainable development of the environment.
