摘　　要：太阳能上升气流塔热发电技术是一项新兴的太阳能热利用技术。本文以干旱半干旱地区草场保护为导向,太阳能上升气流塔装置中进行牧草或其他农作物种植,为养殖用草提供来源以及经济效益,并且在内部集成相变材料储热,调控棚内作物适宜生长温度。结果表明:在经过相同时长的加热及冷却后,相变蓄热层最终的中间层平均温度比铝制蓄热层高1.09%,证明了潜热释放对棚内温度调控的有效性,并且建造太阳能上升气流塔种植系统的成本相对于其他大棚降温设备更低廉,能够在环境友好的前提下牧草种植和太阳能热发电并线运行,实现能源的层级利用。Solar updraft tower thermal power generation technology is a new technology of solar heat utilization.In this paper,guided by grassland protection in arid and semi-arid areas,grass or other crops are planted in the solar updraft tower device to provide sources and economic benefits for breeding grasses,and phase-change materials are integrated into the interior to store heat and regulate the suitable growth temperature of crops in the shed.The results show that:After heating and cooling at the same time,the average temperature of the final intermediate layer of the phase-change absorber is 1.09%higher than that of the aluminum absorber,which proves the effectiveness of latent heat release on temperature control in the shed.Moreover,the cost of the solar updraft tower planting system is lower than that of other greenhouse cooling equipment,which can realize grass planting and solar thermal power generation under the premise of environmental friendliness.Achieve hierarchical use of energy.
