[Abstract]:Green building has the characteristics of friendly with nature, energy saving and high efficiency. It is closely integrated with the elements of site, climate, natural energy and resources. It can effectively meet all kinds of use functions and create a harmonious work and living space with nature at the same time. Multi-function energy system is a kind of total energy system which is compatible with environmental protection. It embodies the idea of integration of multi-energy synthesis and multi-function output, and is the mainstream direction and frontier of the development of energy power system. It is also an important form of economic, efficient and large-scale application of renewable energy in buildings. Based on green building and multi-function energy system, based on the idea of bionics, this paper puts forward a green building multi-functional energy system, which follows the principle of "opening up resources and reducing expenditure, using energy scientifically", to the performance of all kinds of energy components inside and outside the building system. The influence of energy grade and its subsystems on energy utilization efficiency was studied. The integration of green building multi-functional energy system takes the integrated cascade utilization of energy and energy as the main line, and considers the characteristics of low grade and multi-working conditions of building energy use system in an all-round way. In this paper, the concept of building energy and space energy saving is put forward, by analyzing the applicability of building energy and system integration design, the role of renewable energy in building energy supply system can be greatly improved, and the energy consumption of building body can be reduced. It also reduces the demand for fossil energy, by analyzing the multifunctional properties of the building envelope, the multiple demands of space and the characteristics of various renewable energy sources, with the help of multi-source heat pumps and energy storage systems, A multifunctional energy system based on building energy is proposed, which can solve most of the energy needs of buildings and create a form of building energy supply system in harmony with nature. Based on the above analysis, this paper also proposes a photovoltaic radiator with the properties of multi-energy output of electrothermal cooling, which can make comprehensive use of solar energy, air source and space low temperature source, compared with the photovoltaic panel with pure power generation. The efficiency of generating electricity can be increased by 3 / 16, and the efficiency of collecting heat is 45%, and the refrigeration capacity is 30 / 80 W / m ~ (2). As a building enclosure structure, photovoltaic radiation plate can also play an active insulation and other role. This multi-functional property enables buildings to optimize energy systems according to their own needs. In addition, a multifunctional energy system based on photovoltaic radiation plate coupled low temperature difference radiation terminal, multi-source heat pump and energy storage technology is proposed, and its integrated design and operation mode are analyzed. Through the engineering practice of 2010 solar energy decathlon competition Sunflower solar house, Dongying Huaxin Environmental Protection Technology Co., Ltd., zero energy consumption comprehensive building, the application performance of the proposed green building multifunctional energy system is studied. The results show that the multifunctional energy system of green building can greatly reduce the building energy consumption, and can completely solve the cold, warm and electric demand of the building under the condition of low comprehensive cost. In this paper, the multi-functional requirements of the building space, the multi-functional properties of the enclosure structure, various renewable energy sources and energy-saving technologies are integrated, which provides a reference for the integrated design and system control of the green building multi-functional energy system. At the same time, it provides a new idea for the utilization of renewable energy in construction and its industrialization development.
