Description
技术领域technical field
本发明涉及新能源与节能环保领域，尤其涉及一种利用海水冷能和热能的空调系统。The invention relates to the fields of new energy, energy saving and environmental protection, in particular to an air conditioning system utilizing seawater cold energy and heat energy.
背景技术Background technique
节能减排是中国能源发展的基本国策，加强用能管理，采取技术上可行、经济上合理以及环境和社会可以承受的措施，降低消耗，合理有效的利用能源是现今发展的趋势。在我国的东南沿海和南部沿海地区，日照较强，夏日都在半年以上，空调使用的耗电量十分巨大，而在北方，海洋会被冰面覆盖，冰面下的水温高于环境温度。Energy saving and emission reduction is the basic national policy of China's energy development. Strengthening energy management, adopting technically feasible, economically reasonable, and environmentally and socially acceptable measures to reduce consumption and rationally and effectively use energy is the current development trend. In the southeast and southern coastal areas of our country, the sunshine is strong, and the summer is more than half a year. The power consumption of air conditioners is very huge. In the north, the ocean will be covered by ice, and the water temperature under the ice is higher than the ambient temperature. .
海水的比热容较土壤或空气大，在夏日，其温度比环境低，在冬日，其温度比环境高，而且深层海水在夏日吸收太阳光线较少，在深度1000米处的水温约为4－5℃，冬日因4℃的海水密度较大，深层海水温度为4℃左右。夏日利用10℃左右的低温海水制冷或冬日利用4℃左右的海水预热，可以节约大量电能。The specific heat capacity of seawater is larger than that of soil or air. In summer, its temperature is lower than that of the environment, and in winter, its temperature is higher than that of the environment. Moreover, deep seawater absorbs less sunlight in summer. The water temperature at a depth of 1000 meters is about 4 -5°C. In winter, the seawater at 4°C is denser, and the deep seawater temperature is about 4°C. Using seawater at a temperature of about 10°C for cooling in summer or seawater at about 4°C for preheating in winter can save a lot of power.
专利CN 104596010A提供了一种直冷式海水空调系统，主要由暖气片、供水泵、抽排水管路、管口电滤器和渗滤池组成。工作原理为将海洋底层低温海水抽上来经过渗滤池过滤，送至防腐蚀暖气片中给用户室内降温，但是其有两个重大缺陷，一是海水中盐分含量高，很难将其完全过滤，盐分会降低金属的使用寿命，会增加管路和暖气片更换次数；二是防腐蚀材料一般为有机材料，其导热系数小，会极大的降低换热器的换热性能，增大系统功耗。Patent CN 104596010A provides a direct-cooling seawater air-conditioning system, which is mainly composed of radiators, water supply pumps, pumping and drainage pipelines, nozzle electric filters and percolation tanks. The working principle is to pump up the low-temperature seawater from the bottom of the ocean, filter it through the percolation tank, and send it to the anti-corrosion radiator to cool the user's room. However, it has two major defects. One is that the seawater has a high salt content and it is difficult to completely filter it. , the salt will reduce the service life of the metal, and will increase the number of pipe and radiator replacements; second, the anti-corrosion materials are generally organic materials, and their thermal conductivity is small, which will greatly reduce the heat transfer performance of the heat exchanger and increase the temperature of the system. power consumption.
