温室地下贮热系统设计研究

Research on Design of the Underground Heat Storage System in Greenhouse

为了降低温室环境调控能耗,根据育苗不同阶段对气温与土壤温度的要求,设计了温室地下贮热系统,并阐述了系统的组成和贮热原理;同时,分析了各设计参数对系统贮热性能的影响。这样不仅为系统设计与理论分析奠定了基础,对其它类似地下贮热系统的设计、研究也具有参考意义。

In order to reduce the energy consumption in the environment control, the underground heat storage system was designed in the greenhouse based on different requirements of air temperature and soil temperature during different seedling phases. This paper introduces the constitution and heat storage principle of the system. At the same time, the influence of design parameters to heat storage performance of the system is analyzed in details, which will not only establish the basis for the system design and theory analysis, but also provide essential reference for the design and study of other similar underground heat storage system.
