Energy Saving and Emission Reduction Promote Air Source Heat Pump Development

The “air source heat pump—floor warming system”, which extracts energy from the air as a heat source and can effectively interface with a low-temperature hot water surface radiant heating system, has never received much attention from the media like this time. With the acceptance of the "Energy-saving Energy Efficiency Research of Air-source Heat Pump, Solar Energy and Low-temperature Hot Water Floor Heating Building Heating System" Ministry of Housing and Urban-Rural Development, People's Daily, Jinghua Times, Beijing News, Beijing Morning Post, China Real Estate News, China After quality reports, HC media and other media have reported on this heating method with the theme of “new heating methods to make the city’s sky blue”, the Beijing TV station “Beijing Youzao” also introduced this new type of heating system. So that the air source heat pump - floor heating system more attention.

The spring is getting brighter

“You watched the Beijing TV station's report on the air source heat pump-floor heating system?” Recently, the air source heat pump-floor heating system has received extensive media attention. This has allowed Beijing Wangwang, who has been focusing on promoting this heating system for the past two years. Wu Shi'an, general manager of Anjia New Energy Technology Development Co., Ltd. (hereinafter referred to as “Wang An Jia”) was excited to ask everyone.

Wu Shi'an, who is a participant in the science and technology project of the Ministry of Housing and Urban-Rural Development “energy-saving energy efficiency research of air-source heat pump, solar energy and low-temperature hot water floor heating building combined heating system” disclosed: In recent years, Wang’s main business has been solely engaged in electric floor heating construction. Adjusted to engage in the promotion and application of new energy and floor heating systems, the company's operating conditions are flourishing. Due to the shortage of manpower, the project the company is currently contracting has already made him overwhelmed. Huang Kaichen, deputy general manager of Guangdong Aoxin Heat Pump Air Conditioning Co., Ltd., was also thrilled that the air source heat pump-floor heating system has attracted much attention. After attending the Shanghai Heat Pump Exhibition and the Beijing HVAC Exhibition, Huang Kaichen said excitedly: “Whether it is a heat pump exhibition in Shanghai or a HVAC exhibition in Beijing, air-source heat pump manufacturers have attracted many booths before Visitors to the consultation. From the active use of exhibition companies to carry out product promotion and viewers are very concerned about the air source heat pump products, I am confident about the future promotion of air source heat pump heating products."

In fact, because the air source heat pump - floor heating system has been widely concerned about and excited by the Beijing Tsinghua Sorin Energy Technology Institute (hereinafter referred to as "Tsinghua Solan") Director Jiang Pengbo and Chief Engineer Xu Jie. According to Jiang Bobo, the number of projects for installation of air source heat pump-floor heating systems signed by Tsinghua Solan in recent years has been increasing year by year. Among them, the construction projects of nearly 2,000 square meters of housing for more than 100,000 square meters in a district of Xi’an, Shaanxi Province have all adopted the air-source heat pump-floor heating system developed by Tsinghua Solan, and this project is also the current application of air source heat pump-floor heating system in China. One of the largest single project area. In this regard, Xu Jie is hard to hide his excitement: "We can clearly feel the arrival of spring air-source heat pump-floor heating system."

In fact, since last year, companies that are naturally sensitive to changes in the market environment have already felt the “water temperature” of the gradual warming of the air source heat pump-floor heating system, and have turned their attention to this area. According to Wu Shi'an, only 20 companies producing or installing air-source heat pump-floor heating systems last year had only 20, and at least 100 companies in China have already indicated that they want to promote the heating system. Among them, Zhuhai Gree Electric Co., Ltd. (hereinafter referred to as "Geli") and Daikin (China) Investment Co., Ltd. (hereinafter referred to as "Daikin").

It is understood that Gree is very optimistic about the prospects of air-source heat pump heating market is increasing the attention and promotion of air-source heat pump supporting heating system. At the HVAC exhibition in the past two years, Gree has unveiled its own triple-sourced air-source heat pump system that integrates cooling, domestic hot water, and heating. And last year, the company had already established plans to continuously promote this product in 10 cities across the country. Not long ago, the head of Gree Chongqing Branch took a team of dozens of distributors to actively participate in the floor heating technology exchange meeting organized by Chongqing Wuyi Technical College. They seriously discussed and learned about the air from experts in the industry. Source heat pump products and floor heating systems need to combine the technical conditions and should pay attention to matters. The reason why Daikin was the first supporter of the “Energy Efficiency Research for Air-source Heat Pump, Solar Energy, and Low-temperature Hot Water Floor Heating Building Heating System” project of the Ministry of Housing and Urban-Rural Development was that the company was optimistic about the air source heat pump—the floor heating system was vast. Market prospects.

Wu Shian and Others believe that Gree and Daikin have been paying close attention to the application of air-source heat pump heating systems over the past two years to promote air-source heat pump-floor heating systems, fully demonstrating that this heating system is ushering in its Promotional application of spring. Shanghai Anzhen HVAC Equipment Engineering Co., Ltd. Lin Feng even estimates that in the next five years, all air-conditioning companies will be involved in air-source heat pump heating products.

In recent years, the reasons for the rapid development of air source heat pump-floor heating systems in China have been analyzed. According to Jin Jizong, Secretary-General of the Building Heating Branch of the Beijing Construction Engineering Material Association, this is primarily due to the maturation of air source heat pump technology and installation technology for floor heating systems. . Kim Jong-jung said that in recent years, air-source heat pumps have solved problems such as frost formation and defrosting in low-temperature working environments, thus ensuring efficient heating in cold climates and solving the problem of air-source heat pump-floor heating systems including secondary and secondary workers. Technical loops such as mass loop heat transfer and local heat distribution control. Second, it is the need for energy conservation and emission reduction in China. Jin Jizong said that at present, the heat source for heating and hot water for domestic residents is still coal-based, and it is well-known that coal will emit large amounts of carbon dioxide in the combustion process, which in turn will cause serious air pollution problems. The air source heat pump as the heat source device and the floor heating system as the end system is one of the heating modes with the lowest carbon dioxide emissions. Using the air source heat pump-floor heating system will greatly reduce the carbon dioxide emissions. Therefore, under the background of the country's vigorous advocacy of "energy conservation and emission reduction", the application of air source heat pump-floor heating systems can be described as just the right time.

Healthy development owes the east wind

There is no doubt that the current market environment of this heating system has improved a lot compared with the situation where the air source heat pump-floor heating system was frequently encountered in the marketing process several years ago. However, due to the lack of relevant policy support and industry standards, the promotion of air source heat pump-floor heating systems still faces some resistance. “When we introduce our customers to our air source heat pump heating products, customers often ask whether 'air source heat pump is a renewable energy device' and this makes it originally a renewable energy product but has not been listed as renewable energy. The air source heat pump of the product catalog is currently very sloppy." Speaking of the policy discriminatory encountered in the promotion process of the air source heat pump-floor heating system, a salesperson of air source heat pump products is particularly helpless.

In fact, since the birth of the air source heat pump-floor heating system, its energy-saving effect has been recognized by the relevant departments: On March 28, 2002, the Department of Science and Technology of the Ministry of Construction was responsible for the “air-cooled heat pump heating system for cold regions”. The appraisal results suggest that Tsinghua Solan's above technology "combined with radiation floor heating, used in winter heating in cold areas, reliable operation, safe use, has obvious energy-saving and environmental protection effects, with the domestic first, the international advanced level." In 2008, in the book “Best Energy Saving Case” edited by the National Development and Reform Commission, “100 energy-saving technologies (equipment) are widely used in industrial production and people’s lives in the ten years from 1998 to 2007”, air-source heat pump floor heating technology was impressive. In the column. These two times by the relevant national competent authorities for the air-source heat pump floor heating technology of the affirmation and promotion, are based on the Beijing heating season real-time monitoring of the data obtained as the scientific basis, but let the industry regret that the ground-source heat pump When the water source heat pump was identified as a national renewable energy device, the air pump was removed from the list of renewable energy equipment.

It is understood that on December 17, 2008, the air source heat pump was identified as a renewable energy device in the European Union and enjoyed the corresponding support and subsidies from relevant countries. In countries such as Japan, France, Germany and Australia, for the use of air source heat pump heating users, the country provides a price subsidy of 10%-30% depending on the price of the air source heat pump. In China, only a few cities such as Ningbo, Ningbo, and Tianshui include air source heat pumps as renewable energy or government agencies that have explicitly introduced and encouraged the application of technologies. In stark contrast to the situation of air source heat pumps, both ground source heat pumps and water source heat pumps that can also provide heating sources for residents are listed as national renewable energy devices in China. The units that promote the use of these two types of equipment can therefore enjoy National finance support and subsidies in related areas. Obviously, the identity of air source heat pump non-renewable energy equipment makes it impossible to compete fairly with water source heat pumps and ground source heat pump “stations” on the same starting line.

However, what is gratifying is that in 2012 the National Development and Reform Commission promulgated the "Energy-saving Products Huimin Engineering High-efficiency Energy-Saving Household Water Heater Promotion Regulations", which provided certain preferential policies for air source water heaters. Experts who have been fighting for preferential policies for the development of air source heat pump industry have stated that with the continuous maturation of air source heat pump technology, government authorities should promulgate some favorable policies to promote the development of air source heat pump heating systems.

While enterprises are desperately looking forward to the "policy of the policy," consumers are also looking forward to the arrival of "national standard Dongfeng" for air source heat pump heating products. Some consumers stated that the air source heat pump heating products on the market are mixed and mixed. Some manufacturers claim that their air source heat pump units can fully adapt to the cold weather in the winter in the north, but actually “hidden” electric auxiliary heating devices in heat pump units. It is this kind of electrical auxiliary heating devices that make many home owners' winter heating costs ridiculously high.

As for the phenomenon of false publicity and production products in the air-source heat pump industry, Professor Li Yuanzhe of Tsinghua University once called for: Air-source heat pump manufacturers should start from their own, strengthen self-discipline, and ensure product quality through standardized production. However, according to Kim Jizong, Beijing Municipal Construction Engineering Material Association and the Beijing Architectural Design and Research Institute compiled the “Guidelines for the Application of Residential Air-source Heat Pump Heating and Solar Domestic Hot Water Combined System Technology” to Beijing’s housing and urban and rural areas. The approval of the construction committee will help to better regulate and promote this building energy-saving heating technology.
