Intended for use on larger air conditioning projects, Daikin Europe has extended its R-410A Sky Air Super inverter driven range of air conditioning systems with the addition of new 8HP and 10HP versions. Designated RZQ200 and RZQ250 the units offer cooling capacities of 20 and 25kW and heating capacities of 23 and 27kW respectively. The company claims that the units generate maximum energy efficiency, particularly in ?mid? to ?low? load settings, thereby reducing electricity consumption. Motor efficiency has also been improved by optimisation of the inverter sine wave curve, which evens out motor rotation characteristics, while use of a DC fan motor is claimed to provide good operating efficiency.
