Daikin Europe N.V. has introduced a mini heat pump version of its R-410A VRVIII air conditioning system. Designated VRVIII-S, the new version operates both on single and 3-phase electrical supply and is available in 4, 5 and 6hp models with capacities of 11.2, 14.0 and 15.5kW (cooling) and 12.5, 16.0 and 18.0kW (heating).
Intended as an extension to the VRVIII system, VRVIII-S is designed for installation in six to nine unit applications and is therefore, ideal for use in the light commercial sectors. A particularly important feature is the ‘night quiet’ mode, which can be set to cut in automatically eight hours after peak daytime temperature and run for nine hours before returning to normal operating mode. Alternatively, the night set mode can be customised with site set starting and ending times. During the night time period operating sound of the outdoor unit is reduced progressively in three increments of 3dBA down to 41dBA.
VRVIII-S incorporates all the technically advanced features of the larger VRVIII for example auto charging, an important environmental and installation feature which enables VRVIII-S to control the amount of additional refrigerant charging during commissioning operation.
