摘 要: 将地热水作为农业温室的热源,温室内采用地面辐射供暖技术,充分利用地热资源,降低地热尾水温度。介绍了地热水温室供热系统的流程,计算了温室供热系统的热负荷。结合工程实例,以费用年值为经济指标,对供热系统的设计参数进行了优化设计。 Geothermal water is used as the heat source for agricultural greenhouse where the floor radiant heating technology is applied, which can make full use of geothermal resource and decrease the temperature of geothermal tail water. The flow process of geothermal water heating system in greenhouse is introduced, and the heat load of the greenhouse heating system is calculated. Using annual cost as economic indicator, the design parameters of the heating system is optimally designed based on an engineering example.
