Introduction
To regulate the energy efficiency of room air conditioners (hereinafter referred to as air conditioners) that implement energy efficiency label management
The measurement and inspection work is based on the requirements of JJF 1261.1-2017 Energy Efficiency Measurement and Detection Rules for Energy Products.
Finalize the specification.
This specification replaces JJF 1261.2-2010, compared with JJF 1261.2-2010, except for editorial modifications, the main
To change as follows.
--- The name of the specification was changed from "Room Air Conditioner Energy Efficiency Labelling Metrology Test Rule" to "Room Air Conditioning"
Energy efficiency metering detection rules";
--- Add "Introduction", replace "cited documents" with "reference documents" and replace "terms and definitions" with "
Languages and units of measure";
--- "5.1 energy efficiency labeling" adds "energy efficiency information code" and "energy efficiency" 'leader' information"
And other requirements;
--- The original record format and test report format were revised accordingly (Appendix D, Appendix E).
The previous versions of this specification were issued as follows.
---JJF 1261.2-2010.
Room air conditioner energy efficiency
