Daikin Europe NV has introduced a new air to air heat pump system that’s fitted with a unique front panel that heats up like a conventional radiator and releases warm air into the room.
Called Nexura, it’s designed for heating and cooling residential premises and small offices. Called Nexura FVXG, the system comes in three sizes with heating capacities from 4.5 to 8.1kW and cooling capacities from 3.0 to 5.6kW.
Operating noise is 22dBa in normal operating mode and 19dBA in radiant mode, while the controller’s built-in weekly timer, which allows a 7 day schedule to be programmed with 4 different actions per day.
The Nexura has a COP of 4+ and can be used either in single room format with one indoor unit connected to one outdoor unit or in multiple room format with up to 9 indoor units connected to a single outdoor unit. Indoor units can be built-into enclosures or wall or pedestal mounted.
Extra energy efficiency is achieved via the ‘night set’ mode, which prevents over heating or over cooling and when the timer is switched on, the temperature is set at 2 deg C lower during warming and 0.5 deg C higher during cooling to prevent rapid temperature changes during sleeping hours.
The titanium apatite photo-catalytic filter traps microscopic dust particles, breaks down odours and absorbs organic bacteriological and viral contaminants. Overall system control and efficiency is via Daikin’s inverter technology, enabling compressor speed to be varied according to heating or cooling demand.
The company claims this provides stable room temperatures, reducing energy consuming stops and starts, returns energy savings some 30% greater than traditional on/off systems and prevents overloading when other household appliances are in use.
