Refrigeration Express News: China continues to promote energy-saving and environmental protection policies. By 2015, the total output value of the energy-saving and environmental protection industry is expected to reach 4.5 trillion yuan, with an average annual growth rate of more than 15%, becoming a new pillar industry of the national economy. Meanwhile, Japan has long had a mature energy efficiency leader system covering products such as color TVs, air conditioners, washing machines, and refrigerators. China began to explore the introduction of a similar system in 2013, promoting energy-saving and environmentally friendly products, expanding market demand, and boosting consumption of energy-saving and environmentally friendly products. In October 2013, the replacement of old and new energy efficiency standards for variable frequency products led to a comprehensive upgrade and transformation of air conditioner products, and further accelerated the elimination of fixed-speed air conditioners from the market by variable frequency air conditioners. For consumers, the introduction of this energy efficiency standard is more conducive to eliminating their concerns about the cost of using new products. All signs indicate that high efficiency and energy saving are the trend, and the air conditioning industry is entering the era of variable frequency. DC motors for air conditioners, as high-efficiency and energy-saving components replacing ordinary motors, are also of great significance to energy efficiency level 1 and energy efficiency level 2 variable frequency air conditioners.
