RESIDENTIAL DUCTLESS UNITS
In October 2010, Daikin’s Quaternity™ was re-rated to a SEER level of 26.1, which the company stated makes it the most energy-efficient single room system in North America. The all-in-one appliance provides heating and cooling, dehumidifies the air to a user-defined relative humidity setting, and provides air-cleaning functions. Users can set higher set point temperatures with a 50 percent humidity target, realizing significant energy savings. According to Daikin, Quaternity also has exceptional IAQ features, including Flash Streamer Technology, a multilayered air purifying function which decomposes and removes molecules of allergens and odors by colliding them with high-speed electrons.
The Mitsubishi Electric RedLINK wireless controller communicates through radio frequency and features intuitive operational functions for added convenience.

Fujitsu’s Halycon HFI Flex System allows eight indoor units to be connected to one outdoor unit for whole-home year-round comfort.

The Mitsubishi Electric DOAS works with Mitsubishi Electric VRF zoning cooling and heating systems and supplies outdoor ventilation air to a building.

Daikin’s innovative Round Flow cassette is ideal for open plan applications such as classrooms and offices where variances in temperature and airflow can cause discomfort.
According to Mitsubishi, the wall-mounted controllers look almost identical to traditional wall-mounted thermostats. They feature easy-to-read backlit displays and intuitive operational functions.

Heat Controller InverterFlex mini-splits can be mixed and matched to cool and heat two, three, or four rooms. Each indoor air handler is independently controlled with its own wireless remote and can be set for individual preferences or turned off when not needed.

Released last October, Daikin’s Round Flow cassette is designed to provide 360-degree airflow while reducing drafts, temperature fluctuations, and air velocity. The 3-by-3-foot fan coil units can be combined with Daikin’s VRVIII-S, VRVIII, and VRV-WIII. According to the company, the Round Flow cassette is ideal for open plan applications, such as classrooms and offices, where variances in temperature and airflow can cause discomfort. However, with 23 configurable airflow distribution patterns, it can also be effective in smaller, more intricate spaces, too.
Quaternity™ by Daikin boasts a SEER rating of 26.1.

Offices are ideal locations for ceiling cassettes: The overhead location allows conditioned air to reach cubicles and work areas within a large space. Heat Controller units can be programmed for daily, weekly, and holiday operation for energy savings.
