Large split air conditioners have high COPs to save energy
Daikin has updated its ranges of R410A large split air conditioners.
Daikin Europe has updated its R410A range of FTXS/RXS heat-pump and FTKS/RKS cooling-only wall-mounted split air-conditioning units. The new 50, 60 and 71 class combinations of indoor/outdoor units have maximum COPs of 3.63 and EERs of 3.23. Visual appeal is achieved by a stylish flat design and striking optional all-white or white-and-silver colour schemes. Major technological refinements include Daikin’s high-torque, DC reluctance motor swing compressor, which reduces copper losses by about 30% with an 11% increase in cylinder volume and low-frequency operation. Using a DC fan motor increases efficiency across the motor-speed range by 20 to 40% over standard AC motors. A larger heat exchanger with two rows considerably increases heat transfer. The provision of Daikin’s titanium apatite photo-catalytic air-purifying filter maximises absorption of microscopic articles, decomposes odours, removes bacteria and enterotoxins and deactivates viruses.
