Heat, open trapdoor and make it that dehumidification process is more efficient, the extraneous air of relatively dry is delivered to the bottom of crop, makes work
Thing grows in the environment of a relative stable and uniform；Cold-heat exchanger freezes during summer, and blower fan and wet curtain are engaged and can had
Effect reduces indoor temperature.
（2）Large area uses glass wall, adds illumination, reduces windowing area, reduces the thermal loss caused by windowing,
And keep indoor carbon dioxide to be maintained at a higher level, crop yield can be improved 30% or so.
（3）The rotating speed of blower fan is adjustable so that energy expenditure more optimizes, and energy loss reduces.
（4）Band pressure condition is had been in greenhouse, the inside greenhouse weather with pressure condition is more uniform, and breather pipe is located at
Under planting groove, heating and cooling and titanium dioxide Carbon diffusion beneficial to crop.
（5）Fly net can keep off the insect in the external world in outdoor, and so as to reduce influence of the pest and disease damage to crop, colleague is reduced
The usage amount of agricultural chemicals.
