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。
This paper tests, analyzes and researches the effectiveness of the underground solar thermal system in a vegetable greenhouse in Xining. The results showed that the indoor average temperature of 18 measuring points at 9 sites rose to 17.9, 20.2, 19.1, 18.7, 18.5, 18.7, 18.7 and 18.9 respectively, 18.3 ℃; Compared with the outdoor average temperature, indoor annual average temperature increased by 12.2,9.2,10.8,10.7,10.7,11.1,11.0,11 .2 and 10.3 ℃, respectively. The dynamic balance of heat storage in underground greenhouse was as high as 568GJ. When the indoor temperature and temperature increase after the realization of a variety of vegetables, the annual growth and Evergreen, and produced a certain degree of economic benefits.
