Mitsubishi Electric Cooling and Heating: Makers Of Amazing

Mitsubishi Electric is the true industry leader in ductless units air-conditioning and heat pump technology. If compared with other brands, it is apparent that no other manufacturer surpasses the Mitsubishi Electric performance for quiet, easy-to-use, and energy-efficient operation. Because these ductless units technology carries the Mitsubishi Electric name, you know every product is built to last. Mitsubishi Electric systems deliver the ultimate in comfort control for your home or office. It’s true today and will be comfortably evident for years to come.

Commercial ductless units utilize “variable refrigerant flow” technology (VRFZ). Up to 40 indoor units can be connected to one outdoor unit, capable of 40 or more tons combined capacity. These systems are best for office buildings, hospitals, hotels, and other applications where unique climate is needed in each room. Variable Refrigerant Flow (VRF) systems have been developed to be ecologically sound and energy efficient. The City Multi, a variable refrigerant flow zoning (VRFZ) system from Mitsubishi Electric HVAC Advanced Products Division, features inverter technology and simultaneous cooling and heating, making it ideal ductless system for a wide variety of applications.

The City Multi VRFZ systems allow building owners to provide each individual space with its own personalized comfort while realizing energy savings for the owner.  There is a variety of indoor ductless units, including wall-mounted, floor standing, ceiling-recessed and concealed-ducted types.

Mitsubishi Electric continues to advance the category with industry-leading products, training, and support. VRF systems have helped solve complex HVAC challenges in buildings of practically every shape and size across the country.



Residential Multi-Room Ductless Units

Multi-room ductless units can cool or heat multiple separate rooms. These ductless units consist of up to 8 indoor units connected to one outdoor unit (condenser). With combined capacities up to 60,000 BTUh, each indoor air handler can be controlled independently with a full feature remote.

One outdoor compressor powers up all indoor unit, each separately controlled by a wireless remote. This offers a flexible option for configuring your preferred comfort. You can even choose to add units to your compressor in the future after you have already installed just two indoor units (depending on the maximum number of connectable units), allowing for more streamlined expansion or renovation of your home as time and budget allow.

A multi-zone (also called a multi-split) ductless system connects an outdoor unit to an one or more indoor units, letting you control the temperature in several different zones of your home. Variable Refrigerant Flow (VRF) systems are a type of multi-zone ductless systems. VRF systems are energy efficient, and they can be used to heat one zone while cooling a different zone at the same time.




Residential Single-Room Ductless Units

Single zone ductless units are designed to cool or heat one room, these units come in 9,000 to 36,000 BTUh total capacities. Various indoor unit configurations are available. They consist of one indoor ductless unit and one outdoor unit (condenser). Most of single-room ductless units are operated by wireless remote controls and are packed with convenience and comfort features.

Single-room ductless units can be installed so that the indoor unit corresponds directly to outdoor compressor. The compressor sends refrigerant and power to the interior unit via a small pipe, running through a small opening, installed with very little impact to your home.

Various “hot spots” and “cold spots” can be extremely frustrating for homeowners. Window air conditioners and space heaters can help, but they also cost a lot of money to operate. As a result, most homeowners avoid using those rooms in the heat of summer and cold of winter. Closing off access to a library, sunroom or even a bedroom is impractical. It reduces living space and can cause frustration among family members.



Inverter Technology

Ductless units use ultra-quiet Inverter technology, operating at variable speeds, which results in more balanced temperature control, greater energy savings and efficient dehumidification. The computer-controlled compressor’ speed modulates automatically, just like a car on cruise control, so the system is not running constantly at full capacity, but draws energy when it’s needed.

Mitsubishi Electric ductless units are up to 40 percent more energy-efficient than traditional central air systems and window A/C units, potentially saving an average of $440 per year. Where conventional HVAC models maintain temperature by switching the compressor on and off (see graph above), INVERTER-driven compressors are maintained by finely tuned control of compressor speed.
