To reduce global warming worldwide, it is important to spread the use of high energy efficiency products, such as inverter products, to all countries. Daikin Group is developing affordable air conditioners for South East Asian countries and studying ways to evaluate the energy efficiency of the inverter models.
? Inverter technology can reduce power consumption about 58%
Inverters are devices that convert the frequency by controlling the voltage, current and frequency. The inverter controls the compressor motor, the heart of the air conditioner. In addition, with conventional heat exchangers and motors modified, inverter air conditioners use 58% less energy than non-inverter models.
Daikin Group promotes the use of high-efficiency energy-efficient inverter air conditioners so that consumers use less energy during air conditioning and therefore emit less CO2.
? Solution to promote the use of wide frequency inverter products worldwide
Inverter products are more expensive than non-inverters, so they enter the market more slowly in Southeast Asia. However, since 2014, Daikin Group has developed dieu hoa nhat bai an phuc affordable air conditioner, especially for the Asian air conditioning market.
Inverter products are gradually gaining market share due to factors such as more efficient use of energy and increased awareness of energy in the community as a result of rising electricity prices in Southeast Asia. .
To help promote the development of inverter frequency converters, Daikin has created mechanisms for evaluating their energy efficiency. In the past, the most common indicator for evaluating the energy efficiency of air conditioners is the COP, in which energy consumption is calculated by constant efficiency without adjustment. air temperature. However, COP can not be used to properly evaluate the performance of inverter products, operating at optimum levels depending on changes in ambient temperature. Therefore, Japan’s air-conditioning industry has called for a transition to using APF (annual performance factor), and since 2013, APF has been used in ISO standards.
In developing countries, where APF began to be used, Daikin is working with the Japanese government and industry groups to be accepted by the APF as the industry standard and to create energy labeling systems. Partially supports the creation of evaluation criteria.
