First VRVIII heat recovery installed
Daikin Europe N.V. (27/08/2007)
Our First VRVIII heat recovery is installed in the Dynamostraat office building in Rotterdam.
The Dynamostraat office building in Rotterdam-Zuid (southern part of Rotterdam) is the site of the first Daikin VRVIII heat recovery system in Europe. The project is an initiative of BPA BV, with its sister company Maasbouw handling the contracting work and Ster Airconditioning Rotterdam BV the climate control. The six-floor, 12,000-m² building near the multi-functional complex Ahoy will initially be home to two occupants.
Tight specifications ideally suited to VRVIII
BPA wanted a high-quality building with good ventilation, heating and cooling, and the lowest possible energy use. Hence, the project had strict specifications with respect to flexibility in the case of building rearrangement, low energy consumption via heat recovery as well as quiet operation. Daikin was awarded the contract based on the ability of VRVIII to meet these demands and on the professionalism of Daikin A/C Netherlands in handling the tender.
Flexible building zoning
The building will initially house two occupants, the Rotterdam Department of Youth Services and the Department of Social Services, with energy use monitoring per occupant. If in the future another building arrangement is chosen with more occupants, the system must be able to adapt to this and retain energy monitoring per occupant. VRVIII and Daikin’s in-house control system, iManager, meet this requirement, and allow easy reconfiguration of the building zones.
Efficient operation via heat recovery
To obtain the desired optimum energy use, heat recovery was chosen. VRVIII H/R systems allow excess heat generated in one part of the building to be transferred to other parts of the building where heat is needed. VRVIII H/R has the best energy efficiency ratings in the industry, while maintaining the highest levels of comfort due to the possibility of continuous heating during defrost cycles, quick changeover between heating and cooling modes, and the ability to provide optimum climate control per chosen building zone.
Efficiency over previous VRV models is due among others to a 3-10% increase in the airflow rate, a new three-wall heat exchanger supporting increased piping lengths (the longest in the industry, up to 1,000 m), and built-in high efficiency compressor. VRVIII H/R supports 14 types of indoor units. The new system also uses less refrigerant and complies with the European directive on hazardous substances (RoHS).
One of the best specs in the industry
Further VRVIII novelties brought to the BPA project include the system’s ultra-quiet operation during night mode, optimum management of R-410A refrigerant via auto-charge and refrigerant containment check, as well as its unprecedented ease of installation. All of these benefits enable Daikin to meet the strictest requirements.
The BPA building consists of 21 outdoor units and more than 300 FXSQ type ducted indoor units, all managed by Daikin’s iManager control system. The project is scheduled for completion in August of 2007, with the first occupant taking possession on 1 September.
