With the development of “coal to electricity”, clean heating has gradually become a hot word, and air source heat pump is becoming more and more recognized as an important technical means of clean heating. As a large northern province, Shandong has long been in action for reducing coal and coal. In 2017, the list of rural heating pilot counties (towns) was announced, and five pilot counties (cities, districts) and 12 pilot towns were identified to effectively improve the clean heating coverage in rural areas. It is understood that in the first five pilot counties, air source heat pumps have been clearly marked as the main force for clean heating, and the application of air source heat pumps in the Shandong region has also attracted industry attention.

On March 24, 2017, the technical policy of clean heating-air source heat pump heating policy sponsored by China Energy Conservation Association Heat Pump Professional Committee and China Heat Pump Industry Alliance, Danfoss Automatic Control Management (Shanghai) Co., Ltd. and Guangdong Midea HVAC Equipment Co., Ltd. It will be held in Jinan, Shandong Province. The leaders from the China Energy Conservation Association, the Science and Technology Center of the Ministry of Housing and Urban-Rural Development, the Shandong Provincial Energy Conservation Office, the Shandong Provincial Urban and Rural Construction Department, the Shandong Provincial Energy Conservation Supervision Team, and the Shandong Energy Conservation Association have come to the site. To jointly discuss the policy and technology development trend of air source heat pump in 2017.

At the meeting, Song Zhongkui, secretary general of the China Energy Conservation Association and secretary general of the Heat Pump Industry Alliance, first delivered a speech. He mentioned that with the acceleration of development, although the proportion of renewable energy applications is gradually increasing, there is still a gap between the speed and demand of energy development. Under this circumstance, green development has become a necessity. The development of air-source heat pumps has also made a leap forward under the policy push. The release of the policy has also changed from the previous “bottom-up” proposal to the “top-down” promotion. This is a huge boost to the development of the industry, and it also gives enterprises confidence in the future development of the industry, hoping to achieve the industry's output value of 50 billion by 2020. Such a goal is not out of reach. Last year, Beijing had “21 million coal-to-electricity” and air-source heat pumps accounted for 164,000. He said that such a volume will have a greater growth by 2017. It is expected that the application of air source heat pumps in Beijing's “coal to electricity” in 2017 will reach 300,000 sets, while Tianjin, Hebei, Shanxi, Shandong and other provinces. Relevant policies will also be issued one after another. He hopes that through this forum, he can promote better technology and better products, realize the development of the industry through information exchange, promote the coal reduction and coal exchange work in Shandong, and greet the green water and blue sky as soon as possible.

Zhao Hengyi, deputy secretary general of China Heat Pump Industry Alliance, also expressed his views on the policy and market development of air source heat pump heating. In his view, the development of the industry is inseparable from the policy support, and the air source heat pump needs to enter thousands of households. Acceptance and promotion of the government.

Zhang Xuelin, director of sales of central air-conditioning heat pumps in the United States, also introduced air-source heat pump heating products and their applications. Shalu, market application manager of Danfoss Refrigeration Division, proposed a solution to adapt to the heat source of air source heat pump.

In addition to the discussion of air source heat pump trends and product solutions, experts and scholars shared the case and measured analysis of air source heat pumps. Dong Chongcheng, Chairman of the Heating Committee of the Architectural Society of China, conducted a survey and analysis of commercial projects for air source heat pump heating. The actual location was selected at Beijing Zhongguancun International School to test indoor air temperature, outdoor air humidity, temperature, heating system water flow, Supply and return water temperature system electric power and power consumption, etc. Understand the total heating capacity and total power consumption of the heat pump unit during the heating season, analyze the energy efficiency of the whole system, compare the energy consumption difference between the hydraulic balance valve and the temperature control valve, and summarize the application experience. .

   The actual measurement found that the air source heat pump has good heating effect in commercial buildings, and the temperature control valve can effectively control the indoor temperature, and can also improve the energy saving rate of the heating system and the heat pump unit, and is beneficial to the balance valve and the differential pressure bypass valve. The heat pump system operates efficiently and improves the heating quality. Dong Chongcheng also put forward three suggestions: air source heat pump should be installed with temperature control valve for commercial building heating; system operation, unit outlet water temperature should be matched with temperature control valve temperature setting; for installing balance valve, temperature control valve and pressure The system of the differential bypass valve should use a variable frequency water pump.

In addition, Xia Xingchen, the manager of the central air-conditioning heat pump market in the United States, shared the case of the heating project of the air source heat pump. The technical director of the Danfoss Heating Division, Kang Zhuang, also proposed the distribution and end temperature control scheme of the air source heat pump heating system.

Through the convening of this seminar, the participants have a clearer understanding of the policy trend and technological development of Shandong air source heat pump heating. With the further advancement of “coal to electricity”, Shandong may become the Beijing-Tianjin-Hebei Another big province of “coal to electricity”, and the promotion of air source heat pumps in Shandong may indicate that another leap in the industry is coming, but the development of the industry requires each heat pump practitioner to work together. As the coordinator of the event, Danfoss and Midea also acted as the leader in the field of heat pump, and had forward-looking understanding and advanced technical support for the air source heat pump field. In the just-completed heating season, the “coal to electricity” was made. Outstanding contribution, in 2017, how will they perform in this huge market in Shandong? let us wait and see.
