地气热交换水蒸气回收系统的回收量与温室内的环境要素———地气温度差、相对湿度、通风状况有关 .实验结果表明 :地气温度差越大 (>0 ) ,水蒸气回收量就越多 ,地气温度差等于 0℃或小于 0℃时 ,水蒸气回收量为零 ;回收量越多 ,相对湿度的降低幅度就越大 ,相对湿度越高 ,温室内的水蒸气量就越多 ;在温室内保持一定的空气流通性 ,会增加水蒸气回收量 .
The recovery of groundwater heat exchange water vapor recovery system is related to the environmental factors in the greenhouse, ie, the temperature difference of the ground air, the relative humidity and the ventilation status.The experimental results show that the larger the temperature difference (> 0), the water vapor recovery The more the amount of ground air temperature is equal to 0 ℃ or less than 0 ℃, the water vapor recovery is zero; the more the amount of recovery, the greater the reduction of relative humidity, the higher the relative humidity, the amount of water vapor in the greenhouse The more; in the greenhouse to maintain a certain degree of air circulation, will increase the amount of water vapor recovery.
