Description

Solar energy and building integrated composite energy system

technical field

The invention relates to a system in the technical field of energy saving, in particular to a composite energy system integrating solar energy and buildings.

Background technique

Among the huge energy consumption in China, the energy consumption in the construction field accounts for 25-30%, which includes residential heating, air conditioning, lighting, hot water and so on. As a new clean energy, solar energy can be collected and utilized in most parts of China. Integrate the solar-based energy system with the building, provide heating for the building in winter, provide air conditioning in summer, and provide domestic hot water during transitional seasons and other energy saving periods. This method can effectively share the energy demand of buildings, reduce the pressure on the power grid, and clean Safe, no greenhouse gas emissions. At present, conventional energy sources such as fossil fuels are increasingly scarce, and their use costs are getting higher and higher. At the same time, the gradual improvement of building energy conservation will make solar energy occupy a more important position in the future building energy supply. The integration of solar energy and buildings is a very promising Future energy use.

The core of the solar energy and building integrated composite energy system is a reasonable energy utilization method. The longest-developed form of solar energy utilization system is the solar domestic hot water system, but this utilization method has a single function and cannot meet the needs of various energy sources in different seasons of the building. The other is the solar photovoltaic system that has attracted attention in recent years, but this system has high cost and low power generation efficiency, and its role in buildings is not obvious. From the perspective of energy quality, the most suitable way to use it is to use the floor for heating in winter, and to use dry fan coil unit or radiant cooling in summer and cooperate with independent dehumidification system for air conditioning. Because the hot water prepared by solar energy in winter is about 40-50°C, if the hot water in this temperature range is used for convection-based heating methods such as radiators, the efficiency is low, and it is very difficult to use a large-area floor to heat the space through radiation. suitable. In summer, solar energy can be used to prepare hot water near 80°C, which has a certain cooling capacity. However, there are still few systematic ways to use solar hot water for cooling at present, and only a few low-rise large public buildings have adopted absorption cooling. But in fact, in the temperature range of about 80°C, the efficiency of absorption refrigeration is difficult to exert, and for general buildings, the heat capacity of solar collectors cannot match the heat demand of absorbed refrigerant, and the operating effect and economic benefits are poor. Therefore, This refrigeration method is difficult to promote.

After searching the literature of the prior art, it is found that the Chinese invention patent name is: solar floor radiation heating, cooling and hot water supply device, and the application number is: 01224543.7. This patent discloses a heating and cooling system based on radiant floor. The system uses absorption chillers that are only suitable for large low-rise buildings in summer cooling, instead of high-efficiency adsorption technology for heat utilization, and the cooling end uses floor radiation instead of floor radiation, which is more comfortable and controllable Radiant ceiling plus independent dehumidification system.
