摘　　要：利用日光温室燃池加热系统、地中热交换系统的有机结合,在冬季运行,可以提高温室地温及室内气温,并能有效降低温室内湿度 在夏季运行,可有效降低温室内气温等进行测试。结果表明：热交换一侧与对比侧室内平均气温分别为24.7、25.4℃,变化不大。但在风机运行期间（测试期间风机在10：00~16：30运行）,热交换侧与对比侧室内平均气温分别为30.3、35.4℃,平均降温5.1℃ 热交换侧最高气温为32.0℃,对比侧最高气温达38.0℃ 夜间的气温较对比侧略高 地中热交换管道进、出口空气平均温度分别为24.7、19.8℃,平均降低气温4.9℃。Fire-pit and underground heating exchange system in the greenhouse integrated fire pit heating system with un- derground heating exchange system, and this system can increase soil and air temperature, reduce humidity inside green- house during it operating in the winter daytime. Air temperature inside greenhouse was reduced greatly with fire-pit and underground heating exchange system in summer. Testing results indicated that average air temperature was respectively 24. 7℃ ,25. 4℃ both heating exchanged area and contrast area, which temperature difference was small. But average air temperature was respectively 30. 3℃, 35. 4 ℃ both heating exchanged area and contrast area during blower operating （operation time of blower was from 10：00 to 16：30 during testing）, and average air temperature was reduced 5. 1 ℃. maximal air temperature of heating exchanged area was 32. 0℃, and maximal air temperature of contrast area was 38. 0℃. But at night air temperature was higher in heating exchanged area than contrast area. Furthermore experiment results indicated that air average temperature was respectively 24.7℃, 19. 8℃ at import and exit of underground heating -exchanged pipes, and average air temperature was reduced into 4.9℃.
