Building Comfort Solutions
CITY MULTI can be tailored to fit your building. From the moment you sit down with your engineer to design your buildings comfort solution, whether new construction or retrofit, you will see how truly flexible CITY MULTI can be. The modular approach to CITY MULTI allows you to truly customize your system layout. Multiple styles of indoor units are available to fit the unique space and design requirements of each zone. ductless or ducted models give you options for pinpointing precise comfort.
VRFZ (Variable Refrigerant Flow Zoning)
The CITY MULTI VRFZ (Variable Refrigerant Flow Zoning) System takes advantage of inverter technology by varying the speed of the compressor in the outdoor unit to meet the changing load requirements in each of the indoor zones.
CITY MULTI Controls Network (CMCN)
The CMCN manages up to 2,000 indoor units from a single networked PC in terms of operation, monitoring, scheduling (daily, weekly, and yearly), error email, personal browser, tenant billing and maintenance diagnostic information. The CITY MULTI Controls Network (CMCN) put individual, personalized comfort in the hands of the tenants and the building manager. Features include:
- Remote controllers
- On/Off controllers
- Centralized controller
- PC interface
- G-50A web browser
- TG-2000 software
The best way to ensure total comfort is to provide each individual zone with a personalized comfort system.
CITY MULTI’s inverter technology is highly responsive and efficient. By varying the capacity of the system to match your indoor space load requirements whil responding to outdoor conditions, CITY MULTI provides the ultimate in precise indoor comfort control, plus great energy savings.
CITY MULTI Variable Refrigerant Flow Zoning (VRFZ) Systems provide engineers the flexibility to meet their application designs ranging from the simple to the complex. Each CITY MULTI system can be configured for up to 20 zones within a building. Multiple CITY MULTI systems can be integrated into our controls network to air-condition and manage up to 2,000 zones from a single networked computer using Mitsubishi Electric furnished software.
Simultaneous Cooling and Heating (R2-Series)
CITY MULTI systems provide simultaneous cooling and heating operation in fall, winter and spring when the temperature drops below 65°F. So there is a significant number of days when the CITY MULTI R2-Series takes advantage of simultaneous operation while maximizing comfort. This innovation results in virtually no energy wasted by being expelled outdoors. This special function results in optimum energy usage.
Ductless and Ducted Indoor Units
CITY MULTI outdoor units can operate up to 32 ductless or ducted indoor units, making the system ideal for virtually any type of application, or any variety of applications within the same building.
CITY MULTI is designed for the quietest possible operation both indoors and out. Outdoor units are as quiet as 56 dB(A) and indoor units as low as 24 dB(A). That is a huge advantage, especially for classrooms, schools, universities, hospitals, healthcare facilities, and libraries, where quiet conversations are paramount.
LonWorks® and BACnet®
The CMCN supports integration with Building Management Systems (BMS) via our LonWorks® and BACnet® interfaces.
The Mitsubishi Electric HVAC LonWorks® interface, LMAP03U, supports up to 50 indoor units with a variety of network variables on a per indoor unit basis.
The Mitsubishi Electric HVAC BACnet interface, PAC-YG31CDA, is compliant with BACnet/IP (ANSI/ASHRAE 135-1995, 135a) and UDP/IP of Ethernet (ANSI/ASHRAE 135-1995, 135b). Our BACnet interface requires a dedicated network computer configured with the BACnet software license, per G-50A, licensed by Mitsubishi Electric HVAC and the TG-2000 software.
