New High Efficiency VRV® III Heat Pump and Heat Recovery Models from Daikin Europe
Story
Pioneering Daikin VRV climate control technology for commercial buildings is extended with the introduction of new and upgraded VRVIII models with higher COP/EER ratings for both heat pump and heat recovery ranges.
Heat pump range
Efficiency has been increased in the heat pump range with a redesigned small footprint 8 HP model with a COP of 4.50 (+5,4%) and EER of 4.29 (+6.5%) and the addition of a high COP 12 HP model with a COP of 4.37 (+10%) and an EER of 3.89(+12%). Combinations of existing small foot print models and the upgraded 8 HP model offer improved energy efficiencies in variety of configurations, whilst overall efficiency throughout the high COP range also benefits from the inclusion where possible of the new 12 HP high COP model.
Heat recovery range
The extended VRV heat recovery range also benefits from the high COP upgrade and returns the best efficiencies currently available on the market and this is the first time that Daikin has introduced a high COP heat recovery range alongside a small footprint modular range. Upgraded 8 HP units with a COP of 4.31 (+5%) in cooling mode and 4.38 (+2%) in heating mode plus 12 HP units with a COP of 3.84 (+4%) in cooling mode and 4.24 (+1%) in heating are available in stand-alone format. The modular series benefits from the addition of an upgraded 8 HP model and a new high COP 12 HP model.
All the new models also feature automatic refrigerant charging and testing, saving time and ensuring an optimum refrigerant charge for top performance.
Continuous heating
Combination systems using heat recovery models also provide continuous heating during defrost and oil return cycles since only one outdoor coil at a time is defrosted, allowing the other units to continue to provide (reduced) heating capacity to the entire system, resulting in a higher integrated heating capacity and a significant increase in user comfort.
Year round cooling
VRVIII heat recovery models also feature a year round cooling option (known as technical cooling), allowing cooling even at ambient outdoor temperatures down to -20° C and supporting piping lengths to 165m or 1,000m in total. The technical cooling facility can be set up in the field. Rapid changeover from cooling/heating is also possible whilst the ability to control each zone separately – heating or cooling only those rooms where it is needed – keeps operating costs down to a minimum.
