Report Compiled on New Energy Efficiency Standards for Home-use Air Conditioners
February 8, 2022
A working group on energy efficiency standards1 established under the Agency for Natural Resources and Energy (ANRE) has compiled a report on the new energy efficiency standards for home-use air conditioners.
Today, a working group on energy efficiency standards established under the Agency for Natural Resources and Energy (ANRE) compiled the Report on New Energy Efficiency Standards for Home-use Air Conditioners2 after a meeting on January 13, 2022 based on the Act on the Rational Use of Energy (Act No. 49 of 1979). The group has been discussing these standards since December 2019.
Outline of the next energy efficiency standards for home-use air conditioners
Target equipment:
Home-use air conditioners, including those that are non-ducted and wall-hung type, those that are not (cassette-type, through-the-wall, standing, etc.), and those that are multi-type
Target fiscal year:
(1) FY2027 (Non-ducted wall-hung type)(2) FY2029 (other non-ducted wall-hung type, multi-type)
Category:
10 categories are set based on three elements: unit form, cooling capacity, and specifications (Non-cold regions/Cold regions)
Energy efficiency standard:
The next energy efficiency standards for home-use air conditioners are as follows.3 Next energy efficiency standards are expected to have an improvement of up to a maximum of 34.7% (4.0 kW for non-ducted and wall-hung type) compared to current energy efficiency standards.| Unit form | Cooling capacity | Current energy efficiency standard (APF) |
Next energy efficiency standard (APF) |
Improvement rate4 (%) |
| Non-ducted wall-hung type | 2.2 kW | 5.8 | 6.6 | 13.8% |
| 2.5 kW | 5.8 | 6.6 | 13.8% | |
| 2.8 kW | 5.8 | 6.6 | 13.8% | |
| 3.2 kW | 5.8 | 6.6 | 13.8% | |
| 4.0 kW | 4.9 | 6.6 | 34.7% | |
| 4.5 kW | 5.5 | 6.5 | 18.2% | |
| 5.0 kW | 5.5 | 6.4 | 16.4% | |
| 5.6 kW | 5.0 | 6.3 | 26.0% | |
| 6.3 kW | 5.0 | 6.1 | 22.0% | |
| 7.1 kW | 4.5 | 5.9 | 31.1% | |
| 8.0 kW | 4.5 | 5.7 | 26.7% | |
| 9.0 kW | 4.5 | 5.5 | 22.2% | |
| 10.0 kW | 4.5 | 5.3 | 17.8% |

2. Report on home-use Air Conditioners compiled by the Working Group on Classification Standards for Air Conditioners and Electric Water Heaters of the Energy Efficiency and Conservation Subcommittee of the Committee on Energy Efficiency and Renewable Energy under the Advisory Committee for Natural Resources and Energy
3. The table indicates some energy efficiency standards for non-ducted wall-hung type units with a large number of shipments. For details on the next energy efficiency standards, see the attached summary materials.
4. The improvement rates of the next energy efficiency standards are calculated in relation to the current energy efficiency standards. In addition, the next energy efficiency standards are calculated using energy efficiency standards non-cold regions, and the current energy efficiency standards are calculated using energy efficiency standards for dimension-defined type.
