本发明涉及一种利用太阳能、空气能、地热能和空调余热实现冷热电联供系统，属于能源与环境技术领域。The invention relates to a combined cooling, heating and power supply system utilizing solar energy, air energy, geothermal energy and air-conditioning waste heat, and belongs to the technical field of energy and environment.
背景技术Background technique
供热、供冷与供电在现代生产生活中扮演着越来越重要的角色。一个世纪以来，供热、供冷与供电严重依赖于化石燃料。虽然近年来随着超临界朗肯循环等技术的应用，煤电效率逐步提高（现在世界上最新技术已经能达到近50%的热效率），但电力工业依然是二氧化碳及二氧化硫严重污染物主要的排放源，同时随着石化燃料的枯竭，开采的成本和难度会越来越大，因此加大新能源开发的力度，减少对化石燃料的依赖，使用更清洁的能源是目前人类的必然选择。Heating, cooling and power supply are playing an increasingly important role in modern production and life. For a century, heating, cooling and electricity have relied heavily on fossil fuels. Although in recent years, with the application of supercritical Rankine cycle and other technologies, the efficiency of coal power has gradually increased (the latest technology in the world can now reach a thermal efficiency of nearly 50%), but the power industry is still the main emitter of serious pollutants such as carbon dioxide and sulfur dioxide At the same time, with the depletion of fossil fuels, the cost and difficulty of mining will increase. Therefore, it is an inevitable choice for mankind to increase the development of new energy, reduce dependence on fossil fuels, and use cleaner energy.
太阳作为世界上最丰富的永久能源，辐射功率达3.8 x 1023 kW，其中，地球截取的太阳辐射能通量为1.7x 1014 kW，比核能、地热能和引力能储量总和还要大5000多倍。我国属太阳能资源相当丰富的国家，国土面积的2/3地区年日照时数大于2200h，单位面积太阳能辐射总量高达5016MJ/m2。因此，研究太阳能发电技术对我国乃至全人类的持续发展有重要意义。按转换方式的不同，可分为光伏发电及光-热-电两种方式。随着光伏材料（晶材料或非晶材料）生产工艺的日臻完善，光伏发电系统的成本逐渐降低，光伏发电技术也得到越来越多的产业化应用，但一般光伏发电的效率均在10%以内，因此加强对光伏发电系统余热的回收利用，提高太阳能的综合利用效率已成必然选择。As the most abundant permanent energy source in the world, the sun has a radiant power of 3.8 x 1023 kW, among which, the solar radiant energy flux intercepted by the earth is 1.7 x 1014 kW, which is more than 5000 times larger than the sum of nuclear energy, geothermal energy and gravitational energy reserves . China is a country rich in solar energy resources. The annual sunshine hours of 2/3 of the country's land area are more than 2200h, and the total solar radiation per unit area is as high as 5016MJ/m 2 . Therefore, the study of solar power generation technology is of great significance to the sustainable development of our country and even all mankind. According to different conversion methods, it can be divided into photovoltaic power generation and light-thermal-electricity. With the improvement of the production process of photovoltaic materials (crystalline materials or amorphous materials), the cost of photovoltaic power generation systems has gradually decreased, and photovoltaic power generation technology has also been more and more industrialized, but the efficiency of general photovoltaic power generation is 10%. Therefore, strengthening the recovery and utilization of waste heat from photovoltaic power generation systems and improving the comprehensive utilization efficiency of solar energy has become an inevitable choice.
地热能、空气源能与太阳能一样，是一种新的清洁能源，在当今人们的环保意识日渐增强和能源日趋紧缺的情况下，对地热资源的合理开发利用已愈来愈受到人们的青睐。其中距地表2000米内储藏的地热能为2500亿吨标准煤。全国地热可开采资源量为每年68亿立方米，地热量为973万亿千焦。相比空气源，地源场的温度相对稳定，尤其在寒冷或严寒地区，很多时候热泵系统不能用空气源作为低温热源，此时地源将是热泵取热热源的最佳选择。此外，在普通供能系统中，夏季空调时均将冷凝排热直接排外，造成较大能量浪费。因此如何合理综合利用太阳能、地热能、空气能及空调冷凝余热、构建高效供能系统依然是一个重大课题。本发明专利利用光伏电池板的余热辅以空气热源和地热源耦合热泵，辅助加热热泵的取热热源能在空气源和土壤源之间进行切换，空调冷凝余热可用于加热热水，利用一套装置，根据不同的需要实现生活供电、冬季供暖、夏季空调供冷及卫生热水供应，同时有效避免冬季室外余热回收装置冻裂。当前我国正进行新农村城镇化建设，该系统十分适合我国广大村镇（尤其是普通太阳能冬季易发生冻裂的地区）、林牧区等地区因地制宜建设分布式供能系统。Geothermal energy and air source energy, like solar energy, are new clean energy sources. With people's increasing awareness of environmental protection and energy shortages, the rational development and utilization of geothermal resources has become more and more popular. Among them, the geothermal energy stored within 2000 meters from the surface is 250 billion tons of standard coal. The national geothermal exploitable resources are 6.8 billion cubic meters per year, and the geothermal energy is 973 trillion kilojoules. Compared with the air source, the temperature of the ground source field is relatively stable, especially in cold or severe cold regions. In many cases, the heat pump system cannot use the air source as a low-temperature heat source. At this time, the ground source will be the best choice for the heat pump to obtain heat. In addition, in the general energy supply system, the condensation heat is directly discharged outside during air conditioning in summer, resulting in a large waste of energy. Therefore, how to rationally and comprehensively utilize solar energy, geothermal energy, air energy, and air-conditioning condensation waste heat to build an efficient energy supply system is still a major issue. The patent of this invention uses the waste heat of photovoltaic panels to supplement the air heat source and the ground heat source to couple the heat pump, and the heat source of the auxiliary heating heat pump can be switched between the air source and the soil source, and the condensed waste heat of the air conditioner can be used to heat hot water. According to different needs, it can realize domestic power supply, winter heating, summer air-conditioning cooling and sanitary hot water supply, and at the same time effectively prevent the outdoor waste heat recovery device from freezing and cracking in winter. At present, my country is carrying out new rural urbanization construction. This system is very suitable for the construction of distributed energy supply systems in my country's vast villages and towns (especially in areas where ordinary solar energy is prone to freezing and cracking in winter), forest and pastoral areas and other areas according to local conditions.
