How ductless air works
Every building and every situation presents it's own problems with climate control. Architects and engineers have realized this for years, of course, and they have struggled to adapt air-conditioning technology to modern living and working demands. Ductless systems now make the job much easier. Going ductless can mean changing indoor climates from variable and unpredictable to cool and consistent, without expensive renovation work or compromising the structures integrity. And the work can often be done by a professional in a matter of hours.
With a ductless system, simple copper tubing and electrical wiring to indoor units connects a separately installed outdoor unit. Refrigerant is pumped from the outdoor condenser coil and compressor through the tubing to the indoor unit or units. A fan then quietly distributes cool air drawn across the unit's evaporator coil. The amount of cold air entering the room is regulated by an remote control - thermostat. If multiple zones (air handlers) are being utilized, one room - area of a building can maintain a different temperature from another area in the same building thereby satisfying endless comfort levels.
In a central air conditioning system, refrigerant is also pumped from the outdoor condenser coil indoors to a single indoor coil from which cooled air is distributed to each room through a system of ducts. In many houses and businesses, the amount of cold air in one room cannot be regulated without changing the temperature of every room in the building.
The technology behind Mitsubishi Electric Cooling & Heating systems is referred to in many different ways, including mini-split, multi-split, split-ductless, split-zoning, and variable refrigerant flow.
Split-zoning systems allow each room (or space) using an individual indoor air-handler to be controlled independently from other rooms, providing individualized comfort control within each room of a home.
The cooling and heating system requires no ductwork and use two small refrigerant lines plus power and control wiring to connect an outdoor unit to each individual air handler. This allows for easy installation in new construction and causes minimal disruption if you are renovating or retrofitting your home.
The following features highlight the advanced technology, design, and components used in many Mitsubishi Electric Cooling & Heating systems:
INVERTER Technology including INVERTER-driven compressors, electronic linear expansion valves, sensor and information processing components
Advanced processors and system control provide computing power in the indoor units, outdoor units, and remote controllers
Smart Coil™ design and operation uses multiple sensors to maintain coil temperature and regulates refrigerant superheat and subcooling for optimal capacity and performance
Enhanced filtration systems use multiple layers of filtration to improve indoor air quality (IAQ) by helping to remove allergens and odors
Hot-Start™ technology in heat pump systems prevents cool air from blowing during HEAT operation by regulating the fan on the indoor unit so that it does not blow any air until the unit coil has reached the correct operating temperature
i-See™ Sensor scans the upper and lower areas of a room to detect hot or cold spots and adjust temperature and airflow settings in real-time to maintain consistent comfort throughout the space.
Smart Controls on the wall or in your hand provide perfect function, temperature selection, and mode selection plus various timer and program options
