Australia

All single and three phase air conditioners manufactured in or imported into Australia must comply with Minimum Energy Performance (MEPS) requirements. AS/NZS 3823.1.1 and AS/NZS 3823.1.2 and AS/NZS 3823.1.3 cover equipment utilizing one or more refrigeration systems with one outdoor unit and one or more indoor units controlled by a single thermostat/controller. They cover equipment utilizing single, multiple and variable capacity components.

New MEPS and energy labeling requirements for air conditioners with a cooling output up to 65kW came into force on 1 April 2010. Key changes include:

  • All products manufactured or imported have to be registered to AS/NZS3823.2-2009;
  • New ENERGY STAR rating labeling algorithm specified in AS/NZS3823.2-2009 based on annual efficiency (includes non-operating energy);
  • More stringent MEPS levels in cooling mode for many products;
  • Mandatory MEPS in heating mode for all applicable products.

There will be further changes in 2011, key ones include:

  • MEPS levels to be based on annual EER and annual COP (includes non-operating energy namely stand-by power and crank-case heater);
  • Mandatory power factor requirements come into force (minimum 0.85);
  • More information on MEPS and star labeling can be obtained in their website
China
China Energy Regulation

The new energy efficiency standard for fixed speed compressors was implemented officially on June 1st, 2010 and published by General Administration of Quality Supervision and National Standards Commission. The implementation of this new standard has changed the threshold of energy efficiency (from COP 2.5 to 3.2) due to its reduced three levels from the earlier five levels.

India

Energy regulation in India was made mandatory in Jan 2010. The regulation is applicable to systems up to 7kW and single phase windows and wall mounted fixed speeds only.

The Bureau of Energy Efficiency (BEE) was set up in March 2002 to provide a legal framework for the government’s energy efficiency initiatives in the country. Emerson climate Technologies, India has been working closely with BEE in their effort to implement the efficiency program. The table below shows future revisions of 2012 and 2014.

Japan

The Energy Conservation Law, established in 1979, underwent further revisions and in April 1999, introduced the ‘Top Runner Program’ to advance energy efficiency of machinery and equipment. Air conditioners were among the first eleven product items covered under this program.

Top Runner Program aims to raise the energy performance of future products above than that of the most energy efficient product in the current market. For manufactures failing to comply with the obligation, punitive actions (e.g. recommendation, publication of failure, order, penal charges up to 1M yen) are taken against.

Framework of Top Runner program

Target standard value: APF (Annual Performance Factor) – the standard value which manufactures are required to meet. It is set based on the value of the most energy efficient product (Idea of Top Runner) in the category.

Target Fiscal Year: Time limit by when target standard value must be achieved -

FY2010 for RAC: 4kW or lower (started from FY2005) 
FY2012 for RAC: Over 4kW and 28kW or lower (started from FY2007)
FY2015 for PAC: (Started in FY2007)

Judgment method of achievement: Judged on a weighted average for each category per manufacturer. The measurement method is JIS standard. And manufactures are required to display energy efficiency (APF) in catalogs, on product bodies, etc.

South Korea

The five level efficiency standards have become mandatory for both cooling and heating. Heat pumps have a separate standard/method of tabulation. Both these standards take into consideration the seasonal variation.

Taiwan

The new energy efficiency and labeling program for air conditioners with a cooling output of up to 71kW will come into force on January 1, 2011. In case of air-cooled systems, the minimum efficiency level will be increased from the existing level of 2.85 to 3.15.
