Minimum allowable values of energy efficiency and energy efficiency grades for unitary air conditioners
单元式空气调节机能效限定值及能效等级
GB 19576-2019 is a current mandatory Chinese national standard for Minimum allowable values of energy efficiency and energy efficiency grades for unitary air conditioners. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Nov 1, 2020.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to unitary air conditioners driven by motor-driven compressors with an indoor unit static pressure of 0Pa. It specifically covers standard unitary air conditioners, units for computer and data processing rooms, units for communication base stations, and constant temperature and humidity units. This standard does not apply to VRF (Variable Refrigerant Flow) systems, rooftop air conditioning units, or ducted air conditioning (heat pump) units.
Technical requirements
The standard categorizes energy efficiency into three grades, where Grade 1 represents the highest efficiency and Grade 3 represents the minimum allowable value. Products must meet at least the Grade 3 requirements to be legally sold in the Chinese market. The evaluation metrics vary by product type and cooling type (air-cooled or water-cooled), utilizing indicators such as SEER, APF, IPLV, AEER, and COP. For air-cooled unitary air conditioners, the standard sets different grade thresholds based on cooling capacity (CC) ranges, using Seasonal Energy Efficiency Ratio (SEER) for cooling-only models and Annual Performance Factor (APF) for heat pump models. Water-cooled models are evaluated using the Integrated Part Load Value (IPLV). Specialized equipment, such as computer room air conditioners and constant temperature and humidity units, are evaluated using the Annual Energy Efficiency Ratio (AEER). The standard also mandates that products with electric auxiliary heating must have manual switches, visible status indicators, and the auxiliary heating must not automatically activate when the outdoor dry-bulb temperature is 0°C or above. Strict tolerances are defined: the measured energy efficiency value must not be less than 95% of the labeled value, and the calculated seasonal power consumption must not exceed 110% of the labeled value.
Testing methods
Energy efficiency testing must be conducted in accordance with referenced standards. For standard air-cooled and water-cooled unitary air conditioners, as well as constant temperature and humidity units, testing follows GB/T 17758-2010. For computer and data processing room units, testing follows GB/T 19413-2010. Communication base station units are tested according to JB/T 11968-2014. The standard also specifies optional calculation methods for SEER testing under specific temperature conditions.
FAQs
What products are regulated under GB 19576-2019?
It applies to motor-driven compressor unitary air conditioners with an indoor unit static pressure of 0Pa, including units for computer rooms, communication base stations, and constant temperature/humidity types. It excludes VRF systems, rooftop units, and ducted air conditioning units.
Are there any major updates from the previous GB 19576-2004 version?
The 2019 version removes the 'energy efficiency evaluation value' and inspection rules found in the 2004 version. It also revises the energy efficiency grade indicators and updates the minimum allowable values to align with newer industry standards.
How are the energy efficiency metrics like SEER and APF tested under this standard?
Testing is conducted according to referenced national and industry standards such as GB/T 17758-2010 and GB/T 19413-2010, which define the specific laboratory conditions and calculation formulas for these metrics.
