温室地下蓄热系统温度的分布试验

Temperature Distribution of the Underground Heat Storage System in Greenhouse

设计了温室地下蓄热系统,并测试了系统冬季白昼蓄热与夜间加温时温室内空气温度、地坪温度。结果表明,系统蓄热时,温室内纵向最大气温差为1.9℃,地坪温度沿温室横向、纵向变化幅度小,且随着蓄热过程的进行,气温、地温趋于一致;加温时,温室内纵向最大气温差为0.8℃,地坪横向、纵向最大温差分别为0.6℃、1.9℃,温度分布均匀。

An underground heat storage system in greenhouse was designed. In the experiments, the air temperature and floor temperature in the greenhouse were measured during heat conservation in the day and during heating at night in winter. The results indicated that the maximum air temperature difference along longitude of greenhouse was 1.9~C, and the floor temperature varied evenly and tends to consistent along longitude and transverse of greenhouse during heat storage. During heating, the maximum air temperature difference along longitude of greenhouse was 0.8℃, while the maximum temperature difference along transverse and longitude of the floor was 0. 6℃ and 1.9℃ respectively.
