The FS Multi is a variable refrigerant flow (VRF) system that uses a single outdoor unit to independently control multiple indoor units. By communicating with the indoor units, the outdoor unit controls the flow of refrigerant to each one of them to match their cooling or heating loads. This enables independent operation of each of the indoor units, with inverter control providing optimum energy-saving operation. Air conditioning in multiple rooms by a single outdoor unit also means much less construction and a big improvement in the appearance of buildings. And a wide range of indoor models is available to satisfy the needs of different kinds of buildings. Taking advantage of its extensive experience with models for both the home and commercial facilities, Panasonic is ready to provide the ideal air conditioning solution.
The FS Multi is a refrigerant charge-free system (4.0 - 6.0 HP Outdoor unit Only) that does not require a charge of additional refrigerant even when using a full pipe length of up to 90 m. This dramatically shortens the installation time required for charging with additional refrigerant, weight measurement and pressure judgment. It also eliminates charge amount calculation and there's less chance of a cooling capacity shortage due to an incorrect amount of refrigerant being used or other errors.
The total length of the pipe between a system’s indoor and outdoor units can be extended up to 90 metres, with a height difference of up to 30 metres. These ample limits make it possible to place the outdoor unit on the roof. The maximum height difference between indoor units in the same system may be up to 15 metres, thus covering 4 or 5 floors in the same system.
All models of Panasonic’s FS Multi series are equipped with DC inverter compressor technology for higher EER operation. The new design attains quiet and efficient operation whilst reducing running costs.
The cooling function will remain stable indoors even when the temperature out-side drops to -15 ºC, thus meeting users’ different needs. Moreover, the Heating function operates from -15 ºC to 43 ºC.
A host of silencing technologies achieves super-quiet operation. We've also improved operating efficiency and reduced energy consumption.
