What Makes Ductless Systems So Versatile?

Mitsubishi Electric ductless systems offer many benefits in a tidy package for home and business owners in need of a versatile heating and cooling system. The two factors that make ductless systems so versatile – and allow them to easily exceed the performance and efficiency of ducted forced-air systems, baseboard space-heating and window-A/C space-cooling – are their configurable installation options and their advanced features. These are designed to provide superior heating and cooling for a host of applications.

Designed For Versatility

From their origins in Japan during the 1970s, ductless systems were developed by Mitsubishi Electric as a space-saving and whisper-quiet alternative to conventional ducted systemsthat used too much square footage, and noisy window-A/C units that blocked sunlight and consumed too much energy. With a sleek design and quiet operation, ductless systems quickly spread throughout Asia and Europe where a premium was, and still is, placed on every available square foot of office and living space.

Convenient Installation

Mitsubishi Electric leads the industry in ductless system development and innovation, continuously making strides to provide versatile and convenient installation options, which are attractive features of ductless heating and cooling.

The typical ductless installationonly takes one or two days for your Mitsubishi Electric Contractor to perform, depending on the number of air handlers, and the system and home design. The short installation time is a great convenience for busy home and business owners who don’t want to take several hours and days away from their schedule for extending ducts, and finishing and painting drywall. That can be quite a mess to clean up.

Ductless installation is quick and easy (for your licensed Mitsubishi Contractor),;requiring only small apertures – one through the home’s outer wall, and one for each indoor air handler. The primary components of versatile ductless systems are as follows:

  • Outside cabinet: The compressor, condenser and electronics are housed in a metal cabinet outside the home. Rather than the very large outside unit typical of conventional heat pumps and air conditioning systems, the ductless cabinet offers a small footprint, requiring only a small concrete slab for secure mounting. Or the cabinet may be mounted to the outer wall of the home or business.
  • Indoor air handlers: Air in the living space is heated or cooled at the indoor air handlers. The air handlers house the evaporator coil, indoor air quality components (IAQ) and electronic sensors. There are many location options to suit practically any interior design.

Air handlers are typically mounted high on walls to free up space in the room. Another option may be to install the air handler inside the wall, or as a stand-alone floor console. Ceiling installations are quite common. Sleek cassettes may be mounted to the ceiling, or the air handler may be hung flush in a drop-ceiling.

Mini-ducts are useful for heating and cooling a very large room or adjoining spaces, such as a bedroom, bathroom and walk-in closet. The mini-duct installation involves installing the air-handler in the attic or basement. A short duct run extends from the air-handler to one or more supply outlets, which are installed flush in the ceiling or floor. If the ductless system is sized correctly, you may use a mini-duct for two bedrooms.

  • Conduit: A flexible conduit connects the components in the outside cabinet to the indoor air handlers. The refrigerant tubing, condensate suction and power supply are housed within the thin conduit. The conduit is routed through inconspicuous locations in the home, such as inside walls, through crawl space or attic space. If you’re installing a ductless multi-split system with two or more air-handlers, you may opt for simultaneous two-pipe heating and cooling – exclusively from Mitsubishi Electric.

Advanced Features

The performance of today’s ductless systems have moved far beyond the originally-intended design as replacements for window-A/C unitsand space cooling. This is largely due to the high demand of versatile heating and cooling systems, which spearheaded the development of advanced features and performance-driven components, such as inverter-compressor technology.

Ductless systems employ air-source heat pump technology (or cooling-specific ductless systems), and use the same refrigeration principles to provide efficient heating and cooling. The newly-designed Mitsubishi Electric ductless systems have overcome the former hurdles presented to comfort and efficiency by the nature of heat-exchange principles. We have raised the bar by lowering the balance point, the temperature at which the heating load exceeds heating capacity. These are the components and features that make Mitsubishi ductless systems second to none:

  • Inverter-driven compressor: A variable-speed compressor controls the amount of refrigerant flow through the ductless system. This substantially reduces the amount of electricity needed to drive the compressor, and allows for smooth heating and cooling cycles for optimal comfort.
  • Multi-speed air-handler: The indoor air-handlers offer multi-speed oscillating airflow. Multi-speed airflow works wonderfully with variable-speed compressors to maximize energy efficiency and heat exchange.
  • High-efficiency refrigerant: Old ductless systems (and heat pumps) use R-22 refrigerant (sometimes known as Freon). New high-efficiency ductless systems use an ozone-safe refrigerant (R-410A) with a broader range of super-heating and super-cooling, and the ability to work under much higher pressures. R-410A drives ductless heating to new heights, and new temperature lows – well below the freezing mark into single-digit temperatures. This ensures comfortable heating during cold Virginia winter nights.
  • Computerized sensors and electronics: Ductless systems boast a host of sophisticated sensor monitoring, which monitor room temperature from the floor to the ceiling, and monitor coil temperature for optimal heat exchange. When variances in room temperature are detected (hot/cold spots), the ductless system adjusts refrigerant and airflow to maintain comfort.
  • Indoor air quality features: Select models of ductless systems offer multi-stage air filtration and purification. An anti-bacterial filter is used to remove bacteria and viruses from indoor air. Odors are neutralized with a carbon filter, and a washable media filter captures allergens, dust and other airborne particulates.
  • Expansion valve: A thermal expansion valve tightly regulates refrigerant flow into the coils. This boosts performance on all fronts for comfort, efficiency and dehumidification during humid cooling months.

Versatile Applications

The versatility of Mitsubishi Electric ductless systems offers a complete heating and cooling solution with ease of installation, high-performance components, and by the number of applications for which they're used. If you want to convert a garage to a workshop, a ductless system protects your equipment and let’s you work in comfort. If you need to cool a stuffy upstairs bedroom, going ductless makes a lot of sense.

These are some of the home-improvement applications that ductless systems offer sensible heating and cooling solutions:

  • Remodels: Whether you’re converting a deck area into a sun room or converting attic space into a home office or spare bedroom, ductless systems provide practical heating and cooling without the obtrusiveness of extending ductwork. Ductless heating and cooling is especially effective and practical for historic homes that were not constructed with air ducts.
  • Outbuildings: Do you have a workshop, pool house or perhaps a guest house that needs a heating and cooling upgrade? Ductless systems are available in a variety of sizes to match the heating and cooling load of any living space.
  • Additions: Room additions can be particularly difficult to heat and cool without great expense, burdening the existing system by extending ducts or settling for space heating and cooling with baseboard and/or window units. Ductless systems are ideal solutions for room additions with space-saving elements and independent temperature control (zoning system).
  • Multiple zones: Ductless heating and cooling is available with a single indoor air handler (mini-split) or multiple indoor air handlers (multi-split) that are connected to the same outside cabinet. Two-pipe technology by Mitsubishi Electric affords occupants the luxury to adjust heating and cooling independently in each zone. Ductless multi-splits increase the possibilities in home design more than ever. Install an air handler in the garage, a bonus room, media room and more with one system. A multi-split also saves energy by heating or cooling only the zones that are occupied, if desired.
  • Whole-house system: If you are constructing a new energy-efficient home, one or more ductless multi-splits can provide heating and cooling for the entire home. A whole-house installation tends to initially cost more than a conventional forced-air installation, but the benefits of efficient operation, zoned comfort and quick return on investment look and feel very nice year after year. With a ductless whole-house installation, you’ll never waste energy dollars from inefficient air ducts, and the energy dollars you’ll save with a genuine zoning system will add up year after year.
  • Supplemental: After decades of innovative design and advancements, it’s still tough to beat a basic ductless mini-split for efficient and safe spot or space heating and cooling. Since the conduit only needs a small hole in the outer wall of the home, there's no security risk that exists with window-A/C units. And, ductless efficiency and comfort control are still unmatched.
