Phase Change Thermal Storage Solar Updraft Tower:A New Path for Clean Energy Level Utilization
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
