Seasonal efficiency: measuring true performance in real-life situations
Environmental issues such as global warming and decreasing stocks of fossil fuels have resulted in the need for more efficient climate control systems. This has been expressed in aggressive European environmental targets to be met by the year 2020, commonly referred to as the 20-20-20 targets. To effectively realise these targets, Europe has also mandated more realistic measurements of actual system efficiency: so called seasonal efficiency.
Seasonal efficiency is a more accurate representation of actual system performance:
- Where previously efficiency was measured at a single outdoor temperature (35°C for cooling, 7°C for heating), seasonal efficiency uses a range of outdoor temperatures that more accurately reflect actual performance over an entire season.
- Where previously efficiency was measured with systems running at full capacity (most systems seldom operate at full capacity), seasonal efficiency emphasises the more realistic partial load efficiency.
- Where previously efficiency measurements ignored auxiliary modes such as standby, seasonal efficiency includes the significant levels of energy consumption that take place while the system is “off”.
Seasonal efficiency measurements on air conditioning systems thus reward designs that optimise overall energy use over an entire season under real-life conditions.
Daikin continues to rise to the challenge
While the legislation mandating the seasonal efficiency standard for comfort cooling systems under 12 kW will only come into effect in 2013, Daikin Europe N.V. has already taken pioneering steps towards its implementation. In addition to providing industry-relevant input to the legislators drafting the standard, Daikin was the first to already publish season performance figures for its residential and commercial air conditioners and the first (already in 2010) to integrate Eco-design principles (designing for seasonal efficiency) in its Sky Air Seasonal Inverter line for light commercial use.
In line with its leadership role in seasonal efficiency, Daikin Europe N.V. is proud to announce a further expansion of the Sky Air seasonal efficiency portfolio. The improved seasonal efficiency of the new Sky Air units results in substantial energy savings for shops, restaurants, offices, and small hotels.
The Sky Air seasonal efficiency indoor and outdoor portfolio
The Sky Air seasonal efficiency lines offer two paths to seasonal efficiency: the RZOG-L Seasonal Smart for top seasonal efficiency, and the RZOSG-L Seasonal Classic for applications requiring less flexibility. Both lines of outdoor units offer improvements of more than 40%* with respect to present Sky Air systems.
*FCQHG100F + RZQG100L7V1 SEER values compared with previous FCQH100D + RZQ100D9V1
And the full range of indoor units supported by both systems make either solution a logical choice for small business owners concerned about economy and ecology. The new FCQG & FCQHG Round Flow Cassette is setting the standard for comfort and efficiency. It boasts 360° air distribution and optional room and floor sensors, depending on the current room temperature, occupation levels, and even the location of people in the room. The FBQ-C8, FDQ-C, FDQ-B concealed ceiling units feature an inverter driven fan for maximum partial load efficiency, an enhanced controller for optimum, efficient system control, and whisper quiet operation. Completing the line-up are the equally redesigned FVQ floor-standing unit as well as the new FAQ wall-mounted unit, both with a new casing. The FFQ 600x600 4-way blow cassette and FHQG ceiling suspended cassette have been redesigned to be able to deliver high seasonal efficiency values. Thus there is a Daikin seasonal efficiency solution for a range of light commercial applications, and for a range of budgets.
The Sky Air seasonal efficiency portfolio is just one more reflection of Daikin Europe N.V.’s continuous concern for ever-more efficient, cost-effective and environmentally friendly building comfort solutions.
