| 摘 要： | 试验研究了一套主动式太阳能塑料大棚增温系统。它以空气为载热介质，土壤为蓄热介质，白天利用太阳能空气集热器加热空气，由风机把热空气抽入地下，通过地下管道与土壤的热交换，将热量传给土壤储存。夜间热量缓慢上升至地表，从而使土壤保持恒温。经过连续4 d的加温试验得出：与利用自然辐照的对比温室相比，主动式太阳能塑料大棚的夜间气温平均升高3.8℃，地温平均升高2.3℃，系统蓄热量可达228.9～319.1 MJ。试验结果证明，这种结合太阳能空气集热器和土壤蓄热的塑料大棚增温系统，能有效地提高棚内的气温和地温，具有良好的发展前景。

| Abstract: | An active solar heating system with soil heat storage for plastic film greenhouses was studied.In the system,outside air was heated by solar air collector and then pumped into underground pipes.The heat carried by air was transferred through pipes to the soil and stored for use at night.In the night,heat rised slowly to the ground surface to maintain the soil at constant temperature.After continual running of the active solar heating system for four days,it showed that during the night,the average air tempe... |
