BEIJING – China's top economic planner said Wednesday it would ban sales of energy-wasting air conditioners from June 1 by raising the market threshold based on their energy efficiency.
New standards will evaluate each model according to their coefficient of performance (COP), the efficiency ratio of the amount of heating or cooling provided by a heating or cooling unit to the energy consumed by the system. The higher the COP, the more efficient the system.
The standards vary in accordance with an air conditioner's rated power output. The statement said the average COP level would be raised by 23 percent with the advent of the new standards.
The new system divides air conditioners into three categories with the lowest COP requirement being 3.0, the threshold for market entry. Currently, there are five categories with 2.6 being the lowest, and the top three categories with a COP level of at least 3.0 are deemed energy efficient, compared with the 3.4 level in the new system.
China is the world's biggest producer and market for air conditioners, which consume 100 billion kilowatt hours of electricity each year, and more than a third of the total power used in the peak summer time, according to the statement.
The new standards would result in 3.3 billion kilowatt hours of electricity saved each year, said the NDRC.
At present, more than half of air conditioners in the Chinese market are deemed energy efficient, which the NDRC attributed to government efforts to promote energy efficient home appliances through subsidies.
The NDRC said major producers in China already had the ability to make air conditioners in accordance with the new standards.
The standards were formulated by the NDRC in cooperation with China's quality control and standardization authorities as well as major home appliance producers.
