Climate change has turned the planet warmer and heat waves are spreading. Recent studies have shown that the worldwide use of air-conditioning for domestic, commercial and industrial use consumes around 1 trillion kilowatt-hours per year. Avoiding the use of air-conditioning is extremely difficult because of the hot summers especially in warmer countries.

The use of air conditioning, especially in Cyprus, is a necessity because of the high temperatures. However, increasing energy cost and environmental concerns call for  energy efficient air-conditioning systems, that will optimise temperature, air and humidity to provide the ultimate in comfort throughout the year,with minimum energy consumption.

The EU has  legislated  a set of directives that aims to ensure that the greenhouse effects will be minimized, by setting some energy targets for 2020.

These targets, known as the ’20-20-20’, set the following objectives:

  • A 20% reduction in EU greenhouse gas emissions, from 1990 levels
  • An increase by 20% of the share of EU’s energy consumption produced from renewable resources
  • A 20% reduction in the EU’s energy consumption.

In order to achieve the above targets, the EU has established a framework of minimum requirements Eco-Design [2009/125/EC] for energy-related products (domestic electrical appliances, lighting, heating, etc) and products that indirectly affect energy consumption(window frames, glazing).

Regarding the air-conditioning area, as of 1st January 2013, all air-conditioning units with capacities of up to 12 kw (about 40.000 btu/h) are subjected to the Eco-Design directive and need to meet minimum energy efficiency levels. All air-conditioning units that do not comply with the terms of the directive will not be allowed to carry the CE label and therefore cannot be imported and sold anywhere in the EU.

1.1 Seasonal Efficiency

As from 1 January 2013, all air-conditioning products must exhibit the Seasonal Energy Efficiency Ratio (SEER) and Seasonal Coefficient of Performance (SCOP) on their labels. Manufactures are obliged to publish the seasonal labels on a free- access website so that products can be compared easily by customers. The previous method –nominal efficiency- presented an important gap between the registered and the actual efficiency.

The new energy label has many classifications in different colours, varying from dark green (most efficient) to red (least efficient). The information on the label not only includes the seasonal efficiency ratings, and the seasonal coefficient of performance, but also the annual energy consumption and the sound power values for the indoor and outdoor unit.

1.2 Seasonal Efficiency

As from 1 January 2013, all air-conditioning products must exhibit the Seasonal Energy Efficiency Ratio (SEER) and Seasonal Coefficient of Performance (SCOP) on their labels. Manufactures are obliged to publish the seasonal labels on a free- access website so that products can be compared easily by customers. The previous method –nominal efficiency- presented an important gap between the registered and the actual efficiency.

The main differences between the two methods are:

  • Seasonal efficiency, measures heating and cooling performance across a range of outdoor temperatures, over an entire heating or cooling season, whereas the nominal efficiency, measures the performance at one fixed outdoor temperature.
  • Seasonal efficiency measures the performance at various load conditions, whereas nominal efficiency measures the equipment running at full power.
  • Seasonal efficiency takes into account auxiliary modes, such as stand-by, giving a better representation of the real performance of an air-conditioner.

1.3 Daikin in Cyprus

Today Daikin can supply the Cyprus market with a complete line of air-conditioning products that excel not only in terms of their quality characteristics, but also for their top seasonal efficiency ratings.

Daikin offers the perfect balance of temperature and fresh air all year round.
