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 domestic solar water heating systems with a heat storage water tank volume of less than 0.6m³. It covers various types including compact, separate direct, separate indirect, and integral collector storage (ICS) systems. It is essential for manufacturers to ensure their solar water heating products meet the mandatory energy efficiency limits before entering the Chinese market.

技術要求

The standard establishes the energy efficiency grades for domestic solar water heating systems, categorized into Grade 1, Grade 2, and Grade 3, with Grade 1 representing the highest efficiency. It introduces the Coefficient of Thermal Performance (CTP), which is calculated based on the ratio of daily useful heat gain and the average heat loss factor. Specifically, the standard defines the minimum allowable values of energy efficiency as Grade 3, which is a mandatory requirement. Products failing to meet this threshold are not permitted for manufacture or sale. Additionally, the evaluating values of energy conservation are set at Grade 2, serving as a benchmark for energy-saving products. Manufacturers must ensure their products meet at least Grade 3 requirements to comply with Chinese regulations.

試験方法

The evaluation of energy efficiency relies on testing the daily useful heat gain per unit contour aperture area and the average heat loss factor. These parameters must be tested according to the procedures outlined in referenced standards such as GB/T 19141, GB/T 18708, GB/T 26970, and GB/T 26971. Accurate testing under specified conditions is crucial for determining the correct CTP and subsequent energy efficiency grade.

よくある質問

What products are regulated under GB 26969-2011?

It regulates domestic solar water heating systems with a storage tank volume under 0.6m³, including compact, separate, and integral collector storage systems.

Is GB 26969-2011 a mandatory standard?

While most of the standard is recommended, Section 5.3 regarding the minimum allowable values of energy efficiency (Grade 3) is mandatory. Products not meeting Grade 3 cannot be sold in China.

How is the energy efficiency grade determined?

The grade is determined by calculating the Coefficient of Thermal Performance (CTP), which integrates the tested daily useful heat gain and average heat loss factor against standard minimums.

The summary above provides a high-level overview of GB 26969-2011.
