【Abstract】 It is of momentous positive significance of recycling the vapor resource from the agriculture facility such as greenhouses for increasing the amount of water used in facility agriculture, and improving the humidity environment of air in the greenhouse. According to the principle of temperature disparity between soil and air, this paper designed a soil-to-air heat exchange vapor recycling system and it can be used in the agriculture facility, such as a greenhouse. The following preliminary conclusion is obtained by testing the characteristics of the structural system: The recycled amount of vapor in this vapor recycling system of soil-to-air heat exchange is directly proportional to the diameter of the pipes, the length of the pipes and the amount of air pumped.更多还原
