These flexible indoor units were available last year, but only when paired with a multi-zone outdoor condensing system. When coupled with a single-zone heat pump or air conditioning unit, the 9,000, 12,000 and 18,000 BTU air handlers now fit a wider range of installations.
Heating capacity at low outdoor temperatures is achieved through the use of a large heat exchanger and a high-capacity compressor. The systems operate optimally with ambient temperatures as low as -5 F.
The ceiling cassette unit fits conveniently into the space of a standard 22.5-inch ceiling tile. In addition to a larger heat exchanger, Fujitsu has equipped the ceiling cassette units with a two-stage turbo fan, providing even air distribution and two separate airflow streams.
The compact duct unit can be installed horizontally or vertically, and a built-in drain pump allows for installation of the slim duct unit in smaller spaces than traditional units. It requires only 9.4-inches of space in the ceiling or in the wall – almost four inches less than traditional duct units.
Other standard features include a wired remote control, built-in condensation pump and a host of different operating modes. Optional equipment includes backlit controls and a wireless remote control. The RLFCC and RLFCD units are ideal for residential spot cooling applications, or hospital rooms, dorms and office suites.
