Daikin air conditioning systems ready for new EcoDesign requirements
Daikin’s Sky Air Seasonal Smart and Seasonal Classic light commercial air conditioning systems are ready for new European seasonal efficiency legislation introduced on 1 January 2013.
The Energy Related Products Directive is the European Union’s latest response to the Kyoto Protocol. Since 1 January 2013, all air conditioning products with capacities of up to 12kW – typically those used for light commercial and residential applications – have had to meet minimum energy efficiency levels assessed throughout the year. As a result new energy labels have been introduced.
From January, non-compliant products can no longer be imported into Europe or sold by manufacturers. However those already held in stock by a distributor or wholesaler, or awaiting installation, are deemed to be “placed on the market” and can still be sold on through the supply chain.
Daikin’s latest innovations in air conditioning mean its Sky Air Seasonal Smart and Seasonal Classic ranges already meet the new seasonal efficiency legislation and therefore offer customers the highest levels of energy efficiency, reduced energy bills and lower carbon emissions. In fact, the Sky Air ranges also meet the even tighter energy efficiency thresholds coming into force in 2014.
The new seasonal energy efficiency ratings
The new Seasonal Energy Efficiency Ratio (SEER) for cooling, and the Seasonal Coefficient Of Performance (SCOP) for heating reflect more realistic operating conditions than previous measures. They consider seasonal variations by accounting for external temperature and energy efficiency at partial load capacities and take into account the energy consumption of products in auxiliary modes such as standby or off mode, or when the thermostat is off – again reflecting better real-life energy-performance.
Understanding the new energy labels
From 1 January 2013, affected products’ energy labels must show the SEER and SCOP values and energy consumption in both heating and cooling modes. The labels also display the sound power levels of indoor and outdoor units. Manufacturers are obliged to publish seasonal labels and other relevant data on a free access website so that products can be compared easily.
Daikin’s latest air conditioning systems – designed for seasonal efficiencies
Daikin’s Sky Air Seasonal Smart and Seasonal Classic ranges, which are designed for light commercial applications such as shops, restaurants, offices and data rooms, as well as some homes, were launched last year to meet the new legislation.
Their inverter-controlled heat exchangers and compressors have lower energy consumption as they need only the minimum power necessary to match the load. As a result, the units run most efficiently at the partial loads typically required in real life conditions.
The Sky Air ranges feature a number of innovations. Refrigerant tubes in the heat exchanger have smaller diameters than in previous units, allowing more tubes to be used, increasing the available surface area for heat exchange. The new units also use swing compressors (as opposed to the scroll compressors used in previous ranges), that offer better efficiency at partial load conditions. Finally, the shape of the fan has been improved to deliver optimal air flow distribution, with quiet operation.
The Sky Air Seasonal Smart range also features Daikin’s variable refrigerant temperature technology, which improves the comfort of occupants and improves efficiency, because the system continually adjusts the refrigerant temperature (and hence the discharge temperature) according to the total required capacity and weather conditions.
Using intelligent controls is an excellent way to ensure climate is controlled in the most energy-efficient way. Daikin’s new intelligent Touch Manager allows users to set system schedules on a weekly, monthly and annual basis, taking into account holidays and seasonal variations in demand throughout the year. It also enables air conditioning to be integrated with other systems, such as keycard control systems and occupancy sensors. The iTM’s Energy Navigator provides daily and monthly data and energy consumption projections so that performance can be monitored against targets and previous years.
By pinpointing equipment that is not performing in the most efficient way, building managers can adjust how a system operates (for example, switching off air conditioning in unoccupied rooms or at certain times of the day), resulting in smarter energy management and more energy efficient climate control.
With a wide choice of stylish, whisper quiet ceiling, wall and floor units, the Sky Air ranges are flexible enough to suit the needs of any shop, restaurant or office. The equipment is quick and easy to install, whether in a new build or refurbishment project.
Daikin continues to lead the way in energy efficiency
Although the current legislation only affects smaller and light commercial systems at present, consultation is already underway about setting new minimum energy efficiency requirements for systems of over 12kW.
By choosing Sky Air, specifiers, installers and end users can ensure air conditioning equipment meets the latest legal requirements and offers high levels of energy efficiency, thus and reducing energy consumption, carbon emissions and energy bills, while delivering optimal comfort levels.
