Air-conditioner Environmental Program

The higher the coefficient of performance (COP*), the lower the energy consumption. Daikin is making air-conditioners more energy efficient by developing a variety of technologies that save power.

* COP is the energy consumption efficiency. COP = cooling (heating) capacity (kW) divided by rated power consumption. In Japan, COP is the index for energy efficiency performance.

*Results of the efficiency at Daikin’s 8.0kW class for commercial air-conditioners. Defined by the Japan Refrigeration and Air-conditioning Industries Association.

*Results of the efficiency at Daikin’s 2.8kW class for commercial air-conditioners. Defined by the Japan Refrigeration and Air-conditioning Industries Association.

Convenience stores, which are open long hours, have faced issues to
reduce the environmental impacts caused by consumption of large
amounts of energy for air-conditioning, refrigeration, lighting, etc. In order to provide solutions to the issue, Daikin has developed the CONVENI-PACK; a freezing, refrigeration, and air-conditioning system especially designed for the convenience stores; to reduce energy consumption by integrating freezing, refrigeration, and air-conditioning capabilities into one system. The system reduces annual energy consumption by approximately 50% compared to the conventional system by utilizing the heat exhausted from freezers and refrigerators for heating the store in winter. The system was widely recognized for its excellent energy-efficiency and won the FY2003 Award of Minister of Economy*, Trade and Industry of Energy Conservation Grand Award in Japan.

AirNet ECO System
In buildings with multiple air-conditioners that operate for long hours, efficient operation is vital for reducing electricity consumption. That’s why the Daikin Group is developing energy efficient systems that give maximum effect with minimum energy. These systems control the entire air-conditioning system, not just individual air-conditioners, as well as refrigeration equipment systems. An example is the AirNet ECO system*. This system gives energy-efficient operation with minimum wasted energy by analyzing two factors: weather conditions around a customer’s building based on forecasts from 850 weather stations around Japan and calculations from remote monitoring systems based on the operating state of customers’ air-conditioners.

* AirNet ECO System is currently only available in Japan.
