For a long time, solar energy and building applications have mainly focused on domestic hot water, which is limited by multiple factors such as product technology and market demand. For a period of time, the market application has fallen into a phased conundrum. Some real estate developers stated that “solar energy applications must not only be systematically designed in construction drawings, but also be installed and commissioned professionally during construction and installation. If solar thermal energy only provides domestic hot water, it is time-consuming and cost-effective.” But some solar water heaters The company is trying to change this state.

Solar thermal energy is an important step

Recently, Four Seasons Mu Ge formally announced that the solar thermal heating and heating project at General Guanxin Village in Pinggu District, Beijing has achieved stable operation for two consecutive years. The successful application of solar energy in solar energy heating in residential buildings has opened up a large area in the future. Promotion.

The General Pinggu District of Beijing is a gateway to the east end of the Ming Dynasty Great Wall in Beijing. The General Guanxin Village is a demonstration village for new rural construction in China. In May 2009, Four Seasons Mugee provided a solar thermal floor heating system solution for the construction of the entire new village, and completed the system design, construction drawings, installation design, on-site construction, and connected machines from the early stage of the project within 5 months. A series of work such as adjustment and operation monitoring have achieved the promotion of solar thermal energy companies in large-scale construction for heating in winter. Siji Muge consists of solar collectors, storage tanks, controllers, system piping, etc., together with the floor coil heat dissipation system, auxiliary heat source heating system, ground floor heat storage system, etc., through the winter good insulation technology, summer Anti-overheating technology not only achieves radiant floor heating in the heating season, but also provides sufficient domestic hot water in the non-heating season. In addition to the use of solar energy to provide domestic hot water, 171 conjoined villas can also use solar-powered new energy heating in the winter. For only one heating season, they can save up to 2,160 to 3,240 yuan per household.

From the solution of hot water to the supply of heat energy, this is a revolutionary step in the application of solar thermal energy. It marks the integration of solar energy with solar energy as an important part of integrated clean energy solutions. Li Jun, president of Beijing Four Seasons Muge Solar Energy Technology Co., Ltd., said: “The successful application of this project through two winters shows that Siji Muge has become the first company in China to master the solar heating system solution, and it is available in other regions and other projects in the future. Promote the overall strength of solar heating systems."

Solar companies should accelerate transformation

Despite the promotion of policies, solar energy and building integration are showing signs of heavy blowout, but Xu Wei, deputy chief engineer of the China Academy of Building Research, believes that the current integration of solar energy and architecture is mainly to provide hot water for domestic use, and in higher technologies such as heating and cooling. The level of application also lacks large-scale success stories. At the same time, many solar energy companies are mostly manufacturers, and they do not have the ability to solve system problems such as engineering design, construction and installation, and after-sales services.

Liang Junqiang, deputy director of the Building Technology Development Center of the Ministry of Housing and Urban-Rural Development, also pointed out that “The combination of solar energy and architecture must be guided by market demand and provide a personalized and systematic solution. We must not only sell products but more systematically. The service."

In this regard, Jun Li, President of Four Seasons Mu Ge, pointed out that “In the integration and application of solar energy and architecture, after more than 10 years of technology accumulation and marketing, Sige Muge has provided for different cities, different architectural forms, and different functional requirements. The comprehensive strength of the one-stop system integration solution, from solar hot water to solar heating, and cooling in the future, the establishment of solar thermal energy as the main subject for market demand, and compatibility with the auxiliary energy such as electric energy, air energy, and gas New Energy Solutions In addition, Four Seasons Mu Ge proposed the 'urban hot water bank' strategic goal, previously compiled long-range control technology, for civil, commercial, industrial applications and other fields, to provide a safe, convenient, massive solution of light and heat integration. ”

According to Zhang Xiaoyao, deputy general manager of Beijing Four Seasons Mukai, “The layout of the whole industry chain has provided us with powerful power support for system integration experts, and continuous product technology innovation has provided us with rapid response capabilities to meet market demands, from hot water to thermal energy. , From flat plates, glass tubes to metal pipes, from roof-type, balcony-style, embedded, from multi-storey, high-rise and small high-rises, villas to large-scale integrated buildings, from domestic hot water to industrial production, agriculture, and animal husbandry. We can provide personalized, integrated solutions for solar thermal systems.”
