China's ground-source heat pump industry urgently needs to establish a standard system

Abstract: According to Xu Wei, chairman of the National Geothermal Heat Pump Committee, the total area of ​​ground source heat pump used in China reached 139 million square meters by 2009, and the total sales of market-related products have exceeded RMB 1.6 billion. It is estimated that by 2020, the market size of China's ground source heat pump will increase by 5 to 8 times than that at present.

However, in emerging industries with such a large market size, the currently implemented standards are only the national standard “Ground Source Heat Pump System Engineering Specification” (GB50366-2009) compiled in 2009 and revised in 2009, and the national standard “Water source for equipment production”. "Heat pump unit" (GB19409-2003) and a few others, seriously lags behind the development of the industry. From the perspective of the industry's own development, the lack of sound ground source heat pump manufacturing standards and application specifications, the lack of engineering construction quality supervision; from the perspective of industrial policy, the construction and operation of ground-source heat pump project supervision is not strict; these will lead to poor project operation reliability , hinder the healthy development of ground source heat pump technology.

People in the industry call for leading the healthy development of the industry, we must first establish a standard system, rely on norms to lead. During the “12th Five-Year Plan” period, the country will continue to give strong support to the ground-source heat pump industry. Enterprises should seize the opportunity to adjust their development strategies in a timely manner in accordance with market changes, and at the same time strengthen industry self-discipline and learning and improve their own technological level.

He Fang, the secretary general of the Geothermal Heat Pump Professional Group of the China Renewable Energy Society, said that, overall, the market is not regulated and lacks a market access system and a scientific evaluation system. This is the most important factor that restricts China's ground source heat pump technology promotion work. . At the expense of quality, the vicious competition has been growing. At the same time, for the current application of ground-source heat pump in China presents the trend and characteristics of city-level, ultra-large-scale use, whether in terms of technology or management, the risk of mutual heat interference between adjacent ground source heat pump projects should be highly valued. .
