摘要
对西宁市一座蔬菜温室地下蓄集太阳热能系统的功效进行了测试、分析和研究。结果表明：９处１８个测温点的室内年均温分别升至１７．９、２０．２、１９．１、１８．７、１８．５、１８．７、１８．７、１８．９、１８．３℃；与室外年均温相比，室内年均温分别升高了１２．２、９．２、１０．８、１０．７、１０．７、１１．１、１１．０、１１．２、１０．３℃；温室地下增蓄的热量动态平衡值高达５６８ＧＪ。当室内地温和气温升高以后，实现了多种蔬菜的周年生长和四季长青，并且产生了一定的经济效益。
Measurement, analysis and study were conducted on the efficiency of the system of storing the solar heat energy under the ground of a vegetable greenhouse, located in Xining in the QinghaiTibetan Plateau. A total of 18 measuring temperature points was set inside and outside the greenhouse, at the air,the surface of the ground,and 5,10,15,20,40,60,80 cm deep under the ground respectively. The temperature at each point was measured every day for a whole year. Correlation coefficients, regression equations and other parameters were calculated, with results indicating (in the order of points mentioned above) that: 1. the indoor annual average temperatures rose to 17.9,20.2,19.1,18.7,18.5,18.7,18.7,18.9,18.3 ℃ respectively, 2. the indoor temperature increments were 12.2, 9.2, 10.8, 10.7, 10.7. 11.1, 11.0, 11.2, 10.3 ℃,compared with the outdoor annual average temperatures, 3. the dynamic equilibrium of the heat stored under the ground by the system reached to 5.68 GJ. After both the earth and the air temperatures inside the greenhouse rose, many kinds of vegetables grew in and kept it green all the year, and therefore, definits economic benefits were produced.
