CITY MULTI® R2-Series:
The First Two-pipe System that Simultaneously Cools and Heats.
The CITY MULTI R2-Series offers the ultimate in freedom and flexibility. Cool one zone while heating another. Set up zones to maximize simultaneous operation: interior/exterior or eastern exposure/western exposure. Each zone gets the cooling or heating that’s needed at any time.
CITY MULTI R2-Series Variable Refrigerant Flow Zoning (VRFZ) system from Mitsubishi Electric’s HVAC Advanced Products Division offers you the ultimate in enhanced comfort and effective energy usage. Mitsubishi Electric’s CITY MULTI R2-Series outdoor unit uses INVERTER-driven compressor (Variable Frequency Drive) technology to provide highly responsive cooling and heating performance. By responding to indoor and outdoor temperature fluctuations, the system varies power consumption by adjusting the compressor speed to optimize energy usage. The variable-capacity indoor units are controlled by electronic expansion valves. This feature allows operation only at the levels required to maintain a consistently comfortable indoor environment without wasting energy.
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.
Year-round energy savings
CITY MULTI R2-Series VRFZ systems provide continuous energy savings. During warm weather the CITY MULTI R2-Series VRFZ Systems will deliver the precise amount of cooling to the zones requiring cooling. During cold weather, R2-Series VRFZ System provides outstanding heating performance because of the high-speed capabilities of the INVERTER-driven compressor in the outdoor unit.
Most of the year, CITY MULTI R2-Series VRFZ systems operate in partial-load conditions, and the INVERTER-driven compressor runs only at the speeds necessary to provide the required amount of cooling and heating.
Using the same refrigerant circuit, the system provides true zoning configuration by heating one or more zones, while simultaneously cooling one or more additional zones.
Effective energy usage
The total applied capacity of the CITY MULTI R2-Series VRFZ System’s indoor units can be up to 150% of the capacity of the outdoor unit by taking advantage of load diversity and simultaneous cooling/heating operation. CITY MULTI VRFZ Systems are able to satisfy a significantly higher building load by efficiently distributing the capacity to the outdoor unit and indoor units while using much less energy.
