コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

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.

技術要求

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.

試験方法

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.

よくある質問

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.
